350 CALL TO ORDER AND INTRODUCTION

J. Knauss (EXCOM Chairman) convened the 7-8 January 1986 meeting of the JOIDES Executive Ccxnmittee which was held on Molokai, Hawaii. In the opening remarks, Knauss announced that the United Kingdom has formally joined the Ocean Drilling Program (effective 1 October 1985) and welcomed the return of Dr. J. Bowman, as a fu l l meonbeir, to the EXCOM. Knauss also welcomed Dr. M. Friedman, the new EXCOM representative for Texas A&M University and the new Principal Investigator for the ODP (replacing W. Merrell), and Dr. A. Hattori (Ocean Research Inst.). Meeting attendees were formally welcomed to Molokai by C. Helsley (EXCOM representative - Univ. of Hawaii, Inst, of Geophysics).

At this time, Knauss noted the following temporary changes in representation:

D. Spencer substituting for John Steele - Woods Hole Oceano-graphic Institution.

J. Orcutt substituting for W. Nierenberg - Scripps Institution of Oceanography.

351 ADOPTION OF THE MEETING AGENDA

The agenda was amended to include a discussion on the future operations of the ODP (in a broad context), the goals of the program (in view of new drilling techniques) and the inclusion of COSOD objectives into long range planning objectives. The agenda was further amended to include a discussion on the scheduling and timing of Planning Canmittee and the Executive Committee meetings and a discussion on the use of JOIDES RESOLUTION as a research platform by other oceanographic disciplines. These changes were proposed by J.Baker (JOI Inc.) and M. Keen (Canada) respectively. These items were placed under the heading of ANY OraER BUSINESS.

The membership unanimously accepted these changes.

352 MINUTES OF THE EXCOM MEETING, 25-27 SEPTEMBER 1985 (BONN-BAD GODESBURG,FRG)

D. Heinrichs (NSF) suggested the following change to the NSF Report section on page 4, paragraph 1, line 3. The sentence should now read:

"In light of this favorable evaluation, funding for the ODP has been approved for next 3 years at projected levels of support and

no additional evaluations are scheduled for the review of the science of the program."

It was moved by M. Friedman (TAMU) that these minutes be accepted as amended and seconded by B. Biju-Duval (France).

Vote: 15 for, 0 against, 0 abstain

353 NATIONAL SCIENCE FOUNDATIOJ REPORT G. Gross (NSF) reported that the United Kingdom has joined

the ODP and its monbership is retroactive to 1 October 1985. Gross further announced that a signing ceremony has been scheduled at the British Bnnbassy on 13 January 1986 and that EXCOM would be welcome to attend.

With regard to the issue of membership by the USSR and the ESF, Gross had no ne*s to r^xsrt.

D. Heinrichs (NSF) also reported that the addition of the United Kingdom to the ODP w i l l not directly affect the current budget for FY 86 of $32.5 M.

It was noted that the Graham-Rudraan legislation has been recently passed by the US Congress and that this law wil l affect a l l sections of the U.S. federal budget. Heinrichs stated that is unclear in the short term as to what effect this will have on ODP or at the NSF and that more information will be available after March 1986. However, in the meantime, NSF has begun to study the legislation for potential problems and is investigating potential options.

In closing, Heinrichs emphasized the inportanoe of including COSOD objectives into long range planning activities.

354 JOINT OCEANOGRAPHIC INSTITUTIONS REPORT

J. Baker reported that the Performance Evaluation Committee (PBC) has not yet canpleted its report. However, the Committee has met to examine the logging operations, the East Coast Repository and the ODP Databank at L-DGO in October, the shipboard operations at the St. John's, Newfoundland portcall in November, the science operations at TAMU (also in November) and the administrative operations at JOI in December. Generally the PEC indicated that they found the program to be working well and there were good interactions between the subcontractors and the JOIDES advisory groups. Baker further indicated that the report w i l l be ready in February 1986 and presented at the EXOOM meeting in Pipril 1986. Baker also stated that copies of the report could be made available to EXOOM before the meeting.

Discussion:

Knauss: Could you e3q)lain to whan the PEC will report?

Baker: The PEC i s a contractual obligation of the JOI contract with NSF and thus reports to the President of JOI, Inc.

In closing his section of the JOI Report, Baker mentioned that at this time there were no major items to consider concerning the preliminary budget analysis for FY 87. Heinrichs added that i t was agreed with NSF that JOI identify potential budgetary problems for FY 87. NSF will then review these areas with JOI and recormendations will be provided to the EXCCM and ODP Council at the April 1986 meeting. Further at that time the EXOCM may/nnay not require the POM to review the program. The process of review for FY 87 has begun and results (a refined budget and a program plan) will be released in sufficient time for the EXCOM evaluation. In closing, i t was indicated that the PCOM Budget Subconmit-tee w i l l not be asked to review the budget until after i t i s presented to the EXCOM and ODP Council at the J ^ r i l 1986 meeting.

J. Clotworthy reported that JOI met with NSF in October 1985 to ask for guidance in determining target figures for FY 87-88. These figures and their comparison to FY 84-86 are presented in ? )pendix A.

This budget (based on 5 moxibers) was refined for operations by JOI and the subcontractors and modified to provide a contingency in FY 87 to the TAMU budget. This contingency (APPENDIX B), to be included for each year, w i l l cover costs associated with resupply and other problems as operations are extended into the Southern Hemisphere and Indian Ocean. In addition, the change in funding between FY 86 and 87 (Appendix A) reflects an increase (10%) above the budgeted FY 86 costs.

These results were presented to the subcontractors, who examined the amount of funding at the stated level. After examination, TAMU concluded that they could deliver a program with engineering for the upcaning legs and operations at proper levels. However, two problem areas were identified in the TAMU budget: 1) Operations in the Weddell Sea wi l l require an ice patrol vessel; the proposed budget may be $250 K short of the necessary funds; 2) engineering development to support high temperature drilling in the Red Sea may have to be increased. In the L-DGO budget, additional funding (approx. $140 K) w i l l be necessary to purchase another Borehole Televiewer (BHTV) and Multichannel Seismic Tool (MCS). Further, JOI i s trying to hold i t s budget to the FY 86 level of $1.42 M vs. the target of $1.56 M. This includes suE?»rt for the JOIDES Office and the C»P Databank.

Further Clotworthy reported that in order to accomodate the JOI budget, JOI has proposed eliminating the non-U.S. administrative position at the JOIDES Office Ih'FY 87. This action is

proposed as the program is beyond the start-up stage and is now fully operational.

In response to an Action Item fron the September EXCOM meeting, JOI was asked to examine, in terms of funding and time, engineering activities at *IAMU. JOI has conpleted this review and there are 4 legs (Legs 109, 110, 111, in FY 86, and 116 in FY 87) dependent on oonpletion of engineering developnent tasks. Funding and time budgets appear adequate.

Corporate Overhead Absorbed By ODP In responding to ocmnents by EXCCM and PCCM members at earlier

meetings on the role that overhead costs have played during construction of the budgets for FY 85 & 86, J. Clotworthy defined General and Administrative overhead costs, as those that have been incurred for coitnon or joint objectives and which cannot be readily identified with a particular program requironent. These costs include salaries and expenses of corporate officers and accounting personnel and the costs of operating and maintaining corporate o f f i c e r s . General and Administrative overhead i s charged against a l l direct costs (i.e. is charged as a percentage of a l l direct work performed). It was pointed that direct costs or program costs are those readily identified to a particular contract. At JOI, these are (in decreasing size): ODP (the largest) , USSAC activities, NASA projects and NSF projects (the smallest) . Further, Clotworthy presented data that indicated the amount of overhead absorbed by ODP and the components involved (APPENDIX C).

In examining the budget for FY 85-86, Clotworthy pointed out that there were a number of items that were underspent (e.g. Communications) and these reductions (savings) reduced the levy on individual contracts. The figures indicate that the actual corporate overhead costs to the ODP were less than 10% below budget in FY 85. Furthermore, the percentage of overhead costs borne by the ODP contract i s steadily decreasing as other corporate marine science contract activities increase (APPENDIX C).

Discussion:

When asked i f Oregon State Univ. (the next location of the JOIDES Off ice under the present rotation system) was consulted concerning the elimination of the non-US manber of the JOIDES Office, JOI respcmded by stating the OSU had not been consulted and that the issue was open for debate. During discussion, i t was pointed out that the non-US partners i n i t i a l l y thought that the position wcaald rotate among the non-US members. Also in reviewing the effectiveness of the position at the present location (Univ. of Rhode Is.) , both the EXCOM and PCO! chairmen e:qpressed their strong support for the position as T. Mayer has shown great ccxn-petence in handling JOIDES Office/ODP business and has provided a

unique perspective to JOIDES affairs due to his knowledge of the European community. It was the consensus of the non-US manbers that the position should not be eliminated. It was agreed among the non-US members that the issue of support by the non-US members be tabled until the hpril EXCOM meeting. It was recommended by both the US and non-US members of EXCCM that funds be kept in the present budget for the non-US administrative position at the JOIDES Office. EXCOM Motion: The EXCOM reccnmends that funds be restored to the JOI budget for FY 87 to maintain the non-US menber position at the JOIDES Office.

(proposed by Durbaum, seconded by Bowman) Vote: 15 for, 0 against, 0 abstain

After deciding to keep the position in the JOI budget, the EXCOM next discussed whether the job should be f i l l e d on a full-time or part-time basis. There was discussion on the possibility of amalgamating the position with a research post. In the meantime, T. Mayer was asked for his views about the amount of time required for the position. Also the non-US menbers were reminded that a nomination for the job will be needed in the near future.

355 SCIENCE OPERATOR REPORT

P. Rabinowitz reported that for FY 84/85 there was a savings of $550K, the bulk of which came from less than expected expenses during the Miami, Fla. and Norfolk, Va. portcalls. Monies were further saved as the day rate did not increase and from the d r i l l -ship conversion.

TAMU has asked and received a verbal approval from JOI and NSF to appropriate these saved funds for the publication budget in FY 86. Vacancies in the publication staff will be fil l e d at this time and Request for Quotations (RFQ) have been solicited for the publication of the ODP Part B proceedings. These RFQ's have been sent to professional societies and commercial publications (including non-US publishers).

In FY 87, TAMU anticipates no major problems and should able to meet the PCOM objectives as the publications staff w i l l be online and there w i l l non-conservative levels in the drilling inventory. However, i t should be noted that the only half of the funds necessary for the ice patrol vessel are available and that fuel prices and day rates were based on present levels with no contingencies.

Discussion:

Durbaum: When will the development of high-temperature tools be i n c l u d e d i n t o the budget and how are these developments proceeding?

Rabinowitz: Funds for high tenperature tools are included in the FY 87 budget. High-temp, developments are progressing at the Los Alamos Laboratories.

Preliminary Results from Leg 105 (Baffin Bay-Labraidor Sea)

During Leg 105, M. Arthur (URI) and S. Srivastaya (Canada) were the co-chiefs, a total of three locations were drilled: Site 645 (Baffin Bay) and Sites 646 & 647 (Labrador Sea)-APPENDIX D, Sheet 1. The objectives of the cruise were to define the tectonic develofment of the Baffin Bay/Labrador Sea area, to develop the history of paleocirculation through these regions and determine their connection to the Arctic and Atlantic Ocean and finally to determine the timing and nature of major paleoclimatic changes and the frequency of oscillations between glacial and inter-glacial cycles which prevailed in these regions.

Site 645 (Baffin Bay)-APPENDIX D, Sheet 2 At Site 645, seven holes were drilled to a total depth

of greater than 1100 metersf below the seafloor. The material that was recovered included glacial drops tones and other ice-rafted debris and ^nerally was unfossiliferous. Dri l l i n g at this site has recovered a complete L. P l e i s t o c e n e sequence of glacial/interglacial cycles. Furthermore sedimentation rates suggest deposition has occured at ISm/vay.

Site 646 (Labrador Sea) APPENDIX D, Sheet 3

At Site 646, 2 holes were drilled to a total depth greater than 700 meters below the seafloor and penetrated seismic reflectors R3 and R4 (Miocene age).

Site 647 (Labrador Sea) APPENDIX D, Sheet 4

At Site 647, two holes were drilled to basement and penetrated reflector R2 which has been dated to be between 5.6 - 2.2 rm bp.

In presenting data on the weather/oceanographic conditions (APPENDIX E) during Leg 105, Rabinowitz ccramented that no d r i l l ing time was lost due to sea conditions although RESOLUTION did pull-out and re-enter d r i l l sites three times due to icebergs. It was also pointed out that this ability to work in heavy weather demonstrates a major advantage of RESOLUTION.

Leg 106 (Mid-Atlantic Ridge)

The objectives of Leg 106 were both scientific and technical. The scientific objectives were to determine the origin,nature and evolution of ocean crust of zero age at a slowly accreting plate boundary and to determine the processes of magmai generation and crustal accretion. Technically, the challenge was to spud into material of near zero crustal age. The co-chiefs for Leg 106 were R. Detrick (URI) and J. Honnorez (U. of Miami).

Operations were confined to two sites (Sites,648 and 649) along an area 70 km south the Kane Fracture Zone. For Site 648, Rabinowitz presented a l i s t of spud-in and engineering drilling systems that were required in order for the program to be a success. These systems consisted of: 1) a hard rock base structure; 2) a suspension, cementing and release system; 3) down hole coring motors; 4) development of a coring system ccmpatible with the coring motors; 5) d r i l l i n g and coring b i t s ; 6) an external TV/sonar system; 7) a slimmed down sonar tool to be compatible with the coring motor and TV system; 8) a modified re-entry cone with a gimballed seat and 9) special cements and mud system.

The result of this operation is that Leg 106 successfully spud 34 m into beure rock (^pendix F). However, operations were hampered by units of indeteminate thickness composed of volcanic rubble, which degraded hole oohditions and slowed drilling operations. It is proposed that Site 648 be deepened on Leg 109.

Site 649 was drilled along a hydrothermal vent area near the Kane Fracture Zone.

Discussion:

During discussion, the speed of d r i l l i n g operations was questioned and i t was asked i f the speed could be increased by d r i l l i n g with another technique. It was suggested by C. Helsley (Univ. of Hawaii) that JEPCO Drilling Services and/or Craddock Drilling Services be contacted since they have used very viscous drilling muds to d r i l l holes in Hawaii, with diameters similar to the ODP holes, to depths of greater than 2000 ft . in rubbly aa-aa lava. It was also suggested that new downhole seismic techniques be developed in order to determine the thickness of the rubble zone. It was further suggested that TAMU abandon continuous coring during d r i l l i n g and use very viscous drilling mud, with no circulation, after which the hole (in particular the rubble zones) could be logged to determine downhole lithology.

Ship Schedule

Leg 107

Written permission to operate was not received from Italy at the time RESOLUTION departed Malaga, Spairi. However, the US Dept. of State has indicated that a verbal"-agrieement does exist with Italy. Another potisntial problem is that 12 cases containing sen-

sors for the cryogenic magnetometer and spares for the XRF and the top drive system never reached the ship during the Malaga portcall. In hopes of having the equipment to do magneto-stratigraphy, the order of drilling has been reversed so to keep the ship within 100 miles of the I t a l i a n coast. With this strategy, once the cases are located they can be quickly ferried to RESOLUTION without the loss of a cruise objective.

Legs 108, 109 and 110

Staffing has ben cortpleted for the above legs.

Leg 112 (Peru Margin)

R. von Huene and E. Suess have been selected as Co-chiefs.

Leg 113 (Weddell Sea) An ice patrol vessel is needed and TAMU is presently investi

gating whether any drilling permits are required.

Discussion: The main topic of discussion was the problem of clearances.

It was pointed out the ship has s a i l e d three times with clearances caning at the very last second before the cruise. It was suggested during discussion that perhaps the matter of obtaining clearances should be handled on more than a part-time basis. Several EXCOM members were, however, skeptical i f a full-time-position would be an easier solution. The feeling by this group was that possibly too much attention paid to the issue would create even more problans. It was suggested, on the other hand, that perhaps more time is necesscury in asking for permission. In response, TAMU indicated that in previous cases enough lead time was given. However, in each case permission was granted at the last minute. In closing discussion, several EXCOM members suggested that formal and informal contacts for clearances be discussed at the ; ^ r i l EJflOOM meeting.

Workshops

Riser Drilling

TAMU plans to conduct an in-house workshop on riser drilling technology. This will be followed by a larger workshop which w i l l include the JOIDES community and vAiich will be held in conjunction with the TEDOOM.

Co-chiefs

TAMU plans to conduct an in-house workshop with past co-chief scientists in order to receive input for improving operations. The results will be made available to the EXC30M.

10

Discussion: Discussion of general ship operations revealed that the under

way geojîysical equipment is very much underutilized and in most cases not used until the ship ccmes onsite. It was suggested that the reason the problan exists is that with the increased cruising speed of the ship, the records become impossible to collect. A solution would be to slow the ship but this would occur at the expense of d r i l l i n g time. It was also noted that the Univ. of Utrecht has successfully used a profiling system on Royal Dutch Shell ships which reach cp to 18 knts cruisirKj speed and perhaps advice could obtained from them.

Given the stability of the drillship and the potential for the collection of high quality gravity data, i t was suggested that the US Navy be contacted to provide funds to collect such data from the more remote basins in the ocean (e.g. the Southwest Indian Ridge area).

It was also noted that the program has successfully operated for one year. EJCOCM approved a motion recognizing the efforts of a l l involved.

EXCOM Motion: As the JOIDES RESOLOTICW completes its first year of deep-ocean drilling, the JOIOES Executive Ccanmittee congratulates and commends the leaders, scientists and support staffs of the Ocean Drilling Program at Texas A&M University and at Lamont-Doherty Geological Observatory for their outstanding management cind operation of the new program. The acccmplishments of the f i r s t year have met and exceeded our highest expectations. Well done.

(proposed by Knauss, seconded by Heath)


356 WIRELINE LOGGING SERVICES CONTRACTOR REPORT

R. Anderson reported that on Leg 105, the seismic stratigraphy has been completed for a l l the logged holes and that results frcxn the Gamma Ray Spectrometry Tool (GST) log indicated a possible Milankovich cyclicity that may make i t useful for paleoenvironmental ajplications.

With regard to COSOD objectives on bad hole conditions and high temperature tool developnnent, work at L-DGO has produced a variety of tools that could be run through the drillpipe. However, the use of these tools has resulted in operational problems with the tools themselves and the drillpipe. On Legs 108 and 109, a sidewall entry sub will be used to allow tools on the end of the drillpipe to be retracted into the pipe during operations i f a bridge is encountered and-romain in that position until hole conditions improve. After consulting with TAMU and

11

SEDCO engineers, i t was concluded that the system must be modified to f i t within the drillstring.

Other Developments

The f i r s t f i e l d test of the Cryogenic Gaimia Spectrometry Tool is currently planned for Leg 111. This instrument has increased accuracy over the present GST and gives the wt.% of Ni, Mn, Cr, Mg, Na and Ti.

On Leg 109 advanced clay typing, the next generation of o i l field logging tools, will be used to determine wt.% of Al,

Quantitative evaluation of the Wireline Heave Compensator w i l l be conducted on Leg 110 in order to determine i t s response chcuracteristics.

On Leg 109, the German and French heat flow/conductivity magnetic gradicroeter will be used.

L-DGO seeks advice from the geochemical ocnmunity for logging projects that can be developed within the program and which will benefit marine geochemistry.

High Temperature Tool Development

A major impetus for high temperature tool development has come frcMti the Salton Sea Scientific d r i l l i n g project (SSSP) . Schlumberger/SSSP has conducted tests at the Salton Sea by cooling the tool below its failure point while anplacing i t in very hot hole conditions. At this time, however, no other ODP-sponsored development is occurring. L-DGO hopes to borrow other downhole high temp, tools from the USSAC program, US Geological Survey and Lawrence Berkeley Laboratory.

Wireline Packer Development

A proposal has been sent to AMOCO for use of their packer. The proposal consists of a 3 yr. project using their prototype on Leg 112. The prototype must be modified and miniaturized and AMDOO has been asked to develop a set of connections to attach to the bottom of the drillstring. The develcênt of this wet patch connection will allow for the use of other larger diameter tools.

Time in the Borehole In order to educate the JOIDES community to the potential

of logging and thereby increase the amount of time in the borehole through i t s increased use, L-DGO has scheduled a logging school for the PCOM and panel chairmen at their meeting on 20-25 January 1986. Further, the second version of the logging manual will be published in REVIEWS OF GEOPHYSICS. Under this format, topics and tools available for scient i f i c solutions w i l l be

12

presented. In closing this section, Anderson proposed that a logging school be held at each mectbex country.

Discussion: Bowman (UK): What costs are associated with setting up a school

in Europe? Anderson: The b i l l would include travel costs and expenses

associated for three people for one week.

Budget The present budget has a shortfall of $140 K and supple

mental monies cure needed iri order to purchase an additional BHTV and MCS system. Presently the OOP has only one of each and statistics from Schlumberger indicate that the effectiveness of the tools downhole increases from 68 to 91% when 2 tools are available.

The FRG is presently working in the Weddell Sea conducting site surveys using POLARSTERN. However, the austral summer of 1986 has had bad weather and POLARSTERN has encountered many difficulties in conducting seismic surveys in the area (i.e. only 400 km of seismic lines have collected to date). The FRG is also inproving the 3-D magnetometer with a f i e l d test scheduled for Leg 109, i f the PCOM agrees. Work also continues on a high resolution temperature log.

Proposals for d r i l l i n g in the So. China Sea to determine i f i t is the site of a paleo-subduction zone have been submitted to the JOIDES Office. Finally, the geological community of the FRG w i l l hold a colloquium on 13-14 March 1986 at the BGR in Hannover.

France

B.. Biju-Duval reported that France wishes to express i t s welcome to the UK on becoming, a manber of the ODP.

Biju-Duval also reported that in spite of budget cuts in oceanography at IFREMER, the ODP budget has been maintained at present levels for FY 86. This results in FFr 5.6 - 6.5 M available for ODP activities.

13

France is presently considering a multi-channel seismic (MCS) cruise in 1986 to the Red Sea and in 1987 to the southwest Pacific. However, reductions in the submersible program w i l l curtail some of the diving operations planned in 1986. Also, the Red Sea diving cruise, planned in cooperation with the FRG, is presently delayed because of problans in obtaining clearances.

Canada M. Keen reported that Canada wishes to join the rest of the

JOIDES comnunity in welccming the UK to the ODP. In Canada, the ODP i s receiving substantial amounts of

publicity as displays were held at the Canadian Offshore Resources Exposition in Halifax on 1-3 October 1985 and at the Annual Meeting of the Underwater Mining Institute in Halifax on 22-23 October 1985. Further a very successful portcall was conducted at St. John's, Nesi#foundland at the end of Leg 105.

A Canadian National Committee for ODP has been established with P. Robinson as Chairman. W. Hutchisai has been named Chairman of the Canadian COP Council and will act as Canada's representative to the ODP Council. M. Keen will represent Canada at EXCOM meetings and P. Robinson w i l l do the same at PCOM meetings. A secretariat has been established for a period of two years at Dalhousie University. Canadians have been present at a l l panel meetings since September 1985 and w i l l participate on a l l legs with the exception of Leg 107.

In closing, Canada has been active in the Indian Ocean with F. Gradstein developing programs and in the northeastern Pacific through the efforts of Hyndman and Davis of the Pacific Geo-science Centre.

Japan

K. Kobayashi reported that Japan wishes to welcome the UK to the ODP. Since September, two panel meetings have been held in Tokyo and these have given panel members an opportunity to meet with members of the Japanese geoscience community. In addition, a domestic ODP symposium will be held on 11-12 March 1986 in order to discuss ODP results.

Japan has built a high temperature (3-axis) cryogenic magnetometer for use in the East Pacific Rise program.

Japan has also developed the following schedule for site surveys in 1985/86:

United States J. Orcutt reported that USSAC has sponsored a number of work

shops during 1985 and w i l l continue to do so in 1986 (see APPENDIX F) . In the near future, USSAC will issue Requests for Proposals (RFP) for data syntheses of the East Pacific Rise and the Indian Ocean.

During 1986, 3 projects w i l l be jointly funded with the Mcurine Geology and Geophysics section of NSF. These are in the Arabian Sea, as part of the Neogene package, the Deformation Zone area in the Indian Ocean and DSDP Hole 504B in the east Pacific. Monies are also committed for funding site survey cruises to the Broken Ridge area on R/V CONRAD and in the So. Atlantic on POIARDUKE. '

United Kingdom J. Bowman thanked a l l of those who helped get the UK into the

ODP and expressed the enthusiasm of the UK geoscience community especially for Leg 109 activities. The funding to participate in the program was provided by a sizable contribution from the private sector (which consists of 6 UK oi l companies) and from 4 government departments. However, in spite of the involvement of the many contributors, the Natural Envirormait Research Council (NERC) will act as the main clearinghouse for handling funds. The UK coordinating committee w i l l be chaired by M. Audley-Charles and T.J.G. Francis will act as the PCOM representative. The coordinating committee w i l l meet in February 1986 to f i l l JOIDES panel vacancies.

Cruises conducted in Weddell Sea during last year have resulted in the collection of a substantial amount of multichannel seismic data. Tiiis information has been relayed to the JOIDES Office. NERC has conducted GLORIA surveys of portions of the US Exclusive Economic Zone (EEZ) during 1985 and has since joined with Marconi Underwater Systems for the commercial development of the GLORIA instrument. This situation has opened the way for the creation of a R & D program to develop the next phase of this instrument. Bowman reported that DARWIN is scheduled to cperate in the Indian Ocean during 1986.

European Science Foundation

J. Stel thanked the EXOCM for i t s invitation to the meeting and reported that the ESF Consortium met in Zurich after the SeptCTiber EXCOM meeting. At this meeting, the Scandinavian countries as a groisp indicated that they had made a joint request at ministerial levels to increase their i n i t i a l contribution to up to 40-50% of a f u l l subscription and the other ESF countries are expected to also increase their contribution. Fr<xn this show of enthusiasm, i t is hoped that 70-75% of a full ticket will be available in the near future. B. Munsch reported that the ESF has invited Australia to join the ESF Consortivm on the basis of a $300-500 K or 20% contribution and i t is anticipated that a f u l l monbership wil l be obtained by May 1986. The ESF has established a March deadline for a final decision on ODP. Hopefully, there w i l l be a positive decision at the 7 March 1986 ESF meeting in the Netherlands.

Stel also thanked the EXOOM for the series of DSDP Bluebooks and stated that the ESF is pushing for TV exposure for ODP in ESF Countries.

USSR There was no formal report on the membership status of the

USSR. However, several EXCOM members reported that informal contacts suggest a positive stance.

358 PIANNING CONMITTEE REPORT

R. Larson reported on the 8-10 October 1985 meeting of the JOIDES Planning Conmittee.

JOIDES Office Activities The JOIDES Office has produced Vol. XI, Special Issue No.4 of

the JOIDES Journal which is entitled Guide to the Ocean Dr i l l i n g Program. Copies have been distributed to both US and non-US man-bers and institutions. However, a mistake during the binding process has resulted in about 50% of the volunes being mispaginat-ed. A rerun of approximately 1500 copies has been done at no additional costs and a bulk shipment has been made to the non-US member countries. In addition, i f there are requests for individual or bulkmailings from the US, these should be directed to the JOIDES Office.

JOIDES PCOM Membership

The following changes were made at the October meeting:

T. Shipley replaced R. Buffler (Univ. of Texas), who has moved to the OTP Office at NSF.

16

P. Robinson has replaced J. Malpas as the Canadian representative

S. Levi temporarily represented Oregon State Univ. and replaced H. Schrader, who has moved to Marine Geology and Geophysics at NSF. N. Pisias has subsequently been named the PCOM representative from OSU.

JOIDES Panel Manbership The following changes occurred among the JOIDES Panel Chair

men: B. Taylor was named Chairman of WPAC

D. Rea was named Chairman of CEPAC

R. Schlich was named Chairman of lOP

J. Austin was named Chairmain of ARP

Larson also noted that since the October PCOM meeting, M. Purdy has resigned as Chairman of LITHP and M. Arthur has resigned as SOHP Chairman.

Logging At the meeting, the Planning Committee reiterated its require

ment that a standard logging package be run within a reasonable time period in each hole deeper than 400 m. A standard logging package was defined as a suite of sonic, electrical resistivity and active nuclecu: tools.

In an effort to educate the manbers of PCOM and the Panel Chairmen on the capabilities and potential of the logging suite, an evening seminar is planned at the January 1986 PCCM meeting.

SEDCO Limits for Days At Sea

The Planning Committee recognized the concern expressed by SEDOO in balancing the length of the odd and even numbered legs over a 1-2 year period and will include this consideration in its planning of future legs. However, the PCOM indicated that i t must be recognized that because the planning of lengths of legs is guided primarily by their scientific objectives, this consideration may not always be possible.

Panel Staffing

Larson alerted the EXCOM to fact that the present panel structure! may be changed at the January 1986 meeting and requested

17

that EXCOM give guidance to the boundaries of the potential changes. The reason for the potential restructuring relates to whether the panels are presently effective in planning future a c t i v i t i e s due to an apparent duplication of effort by the regional and thematic panels and the general acceptance into the schedule of regional panel d r i l l i n g recommendations at the expense of thanatic panel drilling recommendations. It was also pointed out that the changes would be applied only to the regional and thematic panels and not to the service panels.

Three possible options exist:

1) no change to the present structure. 2) chcinge to only thenatic panels and have working groups report

to them. 3) change to only regional panels and have thematic working

groups report to them. Discussion:

EXCOM Consensus: The present panel structure was emplaced to provide a check and balance system which was deemed necessary for planning. At this time (Jan. 1986), the Program needs stability and not change. PCCM is asked to accept the status quo. If more than minor changes are proposed, they should be brought to the EXCOM for discussion prior to inplementation.

Publications The PCOM reiterated i t s original publications policy of

publishing a Part A and Part B: Proceedings of the ODP. The PCOM Publications Subcommittee has investigated inhouse publication for Part B and has indicated that the $2 M estimated for publishing Part B at TAMU to be comparable to that of other large science operations (e.g. USGS). TAMU has sent RFQs to commercial publishers (e.g. Elseiver, Springer-Verlag) for bids on producing Part B.

Discussion: EXCOM Consensus: The EMXM agrees with the PCOM policy of publishing Parts A & B of the Proceedings of the ODP. It is also recon-mended that any contract with a commercial publisher would include benefits to the ODP i f costs are reduced by innova-tions/iitprovements in publishing.

Present Planning:

Leg 107

Leg 107 i s presently underway with 4 objectives: 1) to establish a Plio-Pleistocene section at DSDP Site 132; 2) to determine the post-and syn-rift history of the E. Sardinian

18

Leg 108

Leg 108 results w i l l concentrate on the shallow and deep circulation history of the NW African margin and the history of paleowind system in the region. The present plan is to d r i l l 12 shallow sites (less than 400 m), with no logging and with double HPC coring and 1 XCB to total depth-Leg 109

Planning i s open for Leg 109; however, i t is likely that i t will be committed to deepening the hole started on Leg 106. The default option is to d r i l l the hydrothermal area near the Kane Fracture Zone (KFZ) or to the transform valley of the KFZ. Leg 110

After consulting TECP and ARP, the PCOM determined the objectives of Leg 110 to be d r i l l through the decollement zone to collect hydrogeologic data above and below the disturbed zone. The default is to conduct a similar study using a series of single bit holes to d r i l l the material above the decollement from the toe area to the upper sections and to d r i l l a reference site (100 km) seaward of the wedge. Leg 111

Planning is open at this time and decisions will be made at the January VCOfl. Leg 112

Planning has not yet been discussed although site surveys have been completed. Leg 113

The PCOM reiterated its view of a 1 January 1987 start date. Leg 114

The PCOM needs an assurance from NSF that funds w i l l be available for site surveys.

Indian Ocean: Red Sea

19

The Red Sea Working Group is devising thanatic objectives. It should be noted that clearances may be a potential problem in this area.

Neogene Package

Plans c a l l for a series of double HPC and XCB sites off the Oman and Sonali margins. The area needs site surveys that wil l be done on CONRAD in mid-1986.

Kerguelen The program w i l l consist of two legs with resi^jply ocurring

at Reunion Is. between the legs.

Eastern Indian Ocean Site survey problens exist for the Broken Ridge, 90°East

Ridge and the Intraplate Deformation areas.

Miscellaneous Sites in the SW Indian Ridge (SWIR) and the Mascarene basin

have been added to the proposed program.

Pacific: Since WPAC is the only group that has considered a drilling

program, planning has been delayed until other appropriate panels have considered possible drilling options.

359 ROTATION OF PLANNING COMMITTEE MEMBERSHIP

In a paper written at the JOIDES Office (APPENDIX H), i t was noted that as of 1 January 1986 ten of the fifteen PCOM manbers w i l l have less than 2 years experience and the incoming PCOM Chairman will have been with the PCOM for only 11 months before taking over the helm. This situation results in a very rapid rate loss of corporate manory.

EXCOM Consensus: EXDOM approved the extension by one year past their planned rotation of J. Honnorez (Univ. of Miami) and/or D. Hayes (L-DGO) in order to provide continuity due to the relative inexperience of the present POCM monbers. It was suggested that future incoming PCOM chairman should serve on PCOM for 1-2 years before becoming chairman.

360 RO^TION OF THE JOIDES OFFICE

The EXCOM considered a position paper written by T. Mayer on the! pros and cons and suggestions for present rotation scheme of

20

the JOIDES Office (APPENDIX I). Also the problem of locating the JOIDES Office after OSU was discus&ed. Under the present plan, the Univ. of Hawaii would be next in line to host the office. However, because of the distance/time problem (from the mainland US) there has been a suggestion that Hawaii be skipped. It was the consensus of the EXOOM that the current rotation plan be maintained. However i t was suggested that some tasks presently carried out at the JOIDES Office could be centralized at JOI and the EXCCM Chairman was asked to determine which tasks could be transferred to JOI. This consensus was expressed in the following motion:

EXCOM Motion: TXCCM recommends continuation of the present system of a two-year rotation with the PCOM Chairman and Secretariat being co-located and that Hawaii be the next location of the JOIDES Office after Oregon State University.

(proposed by Maxwell, seconded by RetLeigh)


361 JOIDES JOURNAL DISTRIBUTION

After reviewing a position paper prepared by T. Mayer on the current distribution of the JOIDES Journal (APPENDIX J), the EXCOM recommended that WHOI, SIO and L-DQO review their practice of distributing issues to their industrial associates.

The issue of distribution to the UK and ESF was not discussed since the UK i s now an ODP manber and membership for the ESF looks favorable in the near future.

362 ANY OTHER BUSINESS OOSOD-2; Long Range Planning of the Ocean Drilling Program

Since the program has completed its f i r s t year of drilling, i t was unanimously agreed by the EXCOM that now i s the time to begin planning and designing a schedule for COSOD-2.

EXCOM Consensus: It was the consensus of the E50CX1M that the COSOD-2 meeting should be held in early 1987. It was further suggested that the PCOM begin a dialog and draft terms of reference for COSOD-2 at i t s January 1986 meeting. The results w i l l be presented at the April EXCOM and the PCOM May 1986 meetings. In addition, after the mandate i s formulated i n January, i t will be distributed by the JOIDES Office to EXCOM for comment. If there are no significant objections from the EXCOM then the PCOM is free to continue with planning. If problems exist, planning will be postponed until the May PCOM meeting. It was also suggested that holding COSOD-2 in Europe would raise the

21

visibility of the program among the Europeans (in particular, the government agencies and the various geological communities).

Timing of EXOCM and PCOM Meetings

Presently the EXCOM is meeting just before the PCOM and this situation is out of phase with the original meeting plan and hampers the EXOOM in its efforts to provide guidance to the POM.

During discussion, R. Larson (PCOM liaison) indicated that the d r i l l i n g program presently constrains the PCOM meeting schedule and this was supported by several of the EXOOM membership. It was also noted that EXCOM is now meeting three times/yr. (and tries to schedule i t s meetings about four months apart) while PCCXA meets three times a year with occasional additional meetings. Scxne EXCOM menbers asked i f there was a real need to meet 3 weeks before the PCOM. Finally, i t was noted that the only firm EXCOM meeting date is that which coincides with the ODP Council. The general consensus was that although i t would be useful to have EXCOM meet a few weeks before POMl, i t was not of such overiding iitôrtance that the EXCOM insist on developing i t s schedule around this goal.

Use of JOIDES RESOLUTION As A Research Platform for Other OoeanograE*iic Disciplines

D. Heinrichs reported that a meeting was held in Woods Hole, Mass. in September -1985 concerning using RESOLUTION as a floating oceanographic platform. Meeting conveners were P. Weibe (WHOI) and C. Miller (OSU) and R. Larson attended from JOIDES. Larson reported that the idea behind the meeting was a good idea in theory but the experimental time frames of potential users (biological, chemical and physical oceanographers) do not match with those of the ship schedule. It appears the interest is on time scales on the order of months, years, decades while the drillship operates in terms of days, weeks or months. After this information, interest in the dri l l s h i p by the potential users quickly waned and they considered other means of emplacing instruments for long periods of time. It was suggested by D. Spencer (WHOI) that there are a limited number of experiments (e.g. sedimait trap studies) for which the ship would be an ideal platform. It was also suggested that, with the advent of riser d r i l l i n g where the ship will be at a location for several months, the interest in using the drillship as an oceanographic platform will increase.

It was further suggested and agreed that i f a new idea were presented to the PCOM, then under present policy, i t could be included on a program.

ODP Brochure

22

NSF and JOI have suggested that the present brochure should be updated. A draft outline has been prepared at JOI that emphasizes the present aspects and the future of the ODP. Presently, the project is being funded by US monies but the format is flexible enough to be used as a base for other countries.

BOS Column J. Orcutt proposed, and discussed with thei JOIDES Office, the

development of an informational column to be placed in EOS to update the public on current and future activities. This column will not compete with the JOIDES Journal and w i l l not report cruise results.lt was also suggested that perhaps information could be sent to agencies in the non-US countries for inclusion in their journals and newsletters.

Third World Participation

J. Knauss reported that he sent letters to the IOC and to the Secretary of SCOR. SCOR informed him that the issue is on the agenda at i t s next annual meeting. Nothing has yet been received from the IOC.

TAMU also has investigated the possibility of establishing Junior Scientist positions for Third World scientists and the costs per person ranged from $22-62 K, depending on the length of stay. Additional details are found in a report to the EXOCM Chairman. The EXCOM Chairman further urged the non-US members to investigate funding possibilities in their respective countries.

363 FUTURE MEETING ARRANGEMENTS

29-30 Pspzil 1986 in Annapolis, Maryland

15-16 October 1986 on Vancouver Is., Canada

The EXCOM thanked C. Helsley for hosting the meeting and making arrangments for the luau and the field trips.

A t the Hawai i EXCOM mee t ing , JOI indicated that they had met wi th NSF i n October 1985 t o ask guidance i n de t e rmin ing t a r g e t f i g u r e s f o r Fy87-88. A pre l iminary analys is o f the prc^xased FY 87 budget by JOI indicated that there were no major items t o be c o n s i d e r e d a t t h i s t ime . I t was agreed that NSF would review potent i a l problem areas wi th JOI and reconnendations w i l l be p rov ided to the EXCOM and the ODP C o u n c i l a t the ^ r i l 1986 meeting. At that time the EXOCM may/may not r e q u i r e the PCOM t o r e v i e w the program.

T h i s l a t t e r o p e r a t i o n y i e l d e d a c r o s s -sec t ional view of an ac t ive hydrothermal vent (APPENDIX A ) . The success o f t h i s was a c r e d i t to the TAMU engineers and to the SEDGO d r i l l i n g team. HonnOrez commended the S i t e Survey p a r t y f o r t h e i r d e t a i l e d mapping o f p o t e n t i a l s i t e s . The success of the o p e r a t i o n was enhanced by u s i n g the M e s o t e c h s o n a r and t h e TV/camera system i n combination to provide precise navigat ion and l o c a t i o n o f the s i t e d u r i n g deployment o f the g u i d e b a s e and during b i t re-entry operations.

In f u r t h e r r ev i ewing Leg 106 ( ^ r a t i o n s , Hcmnorez noted that there were communication plrc^lems between the engineers and the d r i l l e r s and between the s c i e n t i s t s and the t e c h n i c i a n s . In add i t ion , Honnorez suggested that there could be a problan on Leg 109 i f a new d r i l l i n g crew i s used t o the deepen the a l r e a d y established hole and he recommended tha t the SEDOO crew used on Leg 106 be used s i n c e they a r e f a m i l i a r wi th po ten t i a l d r i l l i n g problems. The science party recomnoended the f o l l o w i n g f o r ope ra t i o n s on Leg 109: t ha t more and b e t t e r d r i l l b i t s be designed, that there be more and bet ter designed d r i l l i n g jcurs and t h a t the cementing process be improved to con t ro l the rubble problem encountered on Leg 106. In terms of the s c i e n c e l a b o r a t o r i e s , the s c i ence p a r t y recommended that the X-ray fluorescence (XRF) u n i t be r e p a i r e d and tha t a sample p r e p a r a t i o n a r e a f o r XRF/XRD samples be e s t a b l i s h e d near the XRF/XRD labs . The science party a l so reconinended that the nunber o f spaces f o r petrografAiic microscopes be i n c r e a s e d and t h a t p o i n t c o u n t i n g s tages f o r these instruments be obtained f o r modal ana ly s i s .

Hard Rock D r i l l i n g Guidebase

S . Howard (ODP/TAMU Engineer ing) reported that the assembly of the guidebase took place i n the moonpool o f RESOLUTION i n 17 hours i n d e t e r i o r a t i n g weather c o n d i t i o n s which l as ted 4 days. However, i f condi t ions are r i g h t , the t o t a l time f o r assembly and deployment should be 1 1/2 - 2 days. Due to the s i z e o f the s t ruc ture ( i t only j u s t f i t t e d w i t h i n the moonpool) and weight (40k l b s - i n a i r ) , i t was somewhat d i f f i c u l t to handle during deployment.

Deployment

During deployment, e lec t ron ic beacons on the foot pads determined the he igh t o f the guidebase above the s e a f l o o r and the beacon was landed at the summit of a volcanic plateau (Site 648B-S e r o c k i Volcano) i n an area o f very low s lopes ( l e s s than 5 degrees) covered by recent p i l l o w lavas . The giiidebase was deployed with one l eg i n a f i s s u r e and the o ther three on f i r m ground because the deployment team could not see under the s t ructure . In the fu tu re , a camera w i l l be attached to the s i d e o f the s t r u c ture i n order to provide a view of the foo t ing under each pad.

D r i l l i n g

At S i t e 648A, unsupported bare rock d r i l l i n g was achieved by using the mudmotor to d r i l l a s i n g l e b i t h o l e . A f t e r t h i s s i t e was established the guidebase was lowered on S i t e 648B. In reviewing d r i l l i n g operations (APPENDIX B , sheets 1-4), Howard i n d i c a t ed t ha t the t o t a l t ime f o r d r i l l i n g was 69 hours; the remainder o f the t ime was spent reaming and cenent ing the h o l e . Howard noted tha t the most d i f f i c u l t p a r t o f the operation was rubble col lapse i n the hole . However, the p r o b l ^ eased when the h o l e s i z e was reduced. Another problem noted a t S i t e 648A was the lack of freshwater needed to mix wi th the d r i l l i n g mud. The s i t u a t i o n was somewhat eased by m i x i n g the mud wi th seawater; however, i t was f e l t tha t t h i s s o l u t i o n may have c r e a t e d an a d d i t i o n a l problCTi d u r i n g d r i l l i n g as the v i s c o s i t y may have been changed. Howard concluded the s i t e summary f o r S i t e 648A by i n d i c a t i n g tha t the reason f o r t e r m i n a t i n g ope ra t ions wi th 6 days l e f t i n the program was tha t h o l e c o n d i t i o n s s t e a d i l y w o r s e n e d . The remain ing time o f Leg 106 was spent a t S i t e 649 (Snake P i t hydro-thermal vent area) . At t h i s s i t e cor ing motors were deployed but problems were encountered as another type o f co re catcher was needed to sample the sand-size hydrothermad. sediments.

Engineering Recoimendations

S . S e r o c k i (ODP/TAMU), on b e h a l f o f the o the r ODP/TAMU. engineers, made the fo l lowing recommendations f o r Leg 1 0 9 : c a s i n g should be set 40-60 meters below the seaf l o o r , the hole should be d r i l l e d out w i t h a 1 2 1 / 4 i n c h d r i l l b i t , 10 3 /4" f l u s h j o i n t c a s i n g should then be set and d r i l l i n g continued wi th the 9 7/8" d r i l l b i t . With the smaller diameter h o l e (9 7/8") the p e n e t r a t i o n r a t e shou ld increase dramat ica l ly (APPENDIX B ) . In add i t i on wi th a smaller diameter hole , no more reaming w i l l be necessary as d r i l l i n g w i l l be i n much more s t a b l e c o n d i t i o n s and should r e s u l t in reduced wear on the b i t d e s i g n . F u r t h e r , ODP/TAMU engineers recommended that a va r i e ty of b i t designs wi th improved cu t t i ng s t ructures should be taken on Leg 109 . Hie hole shou ld be e a s i e r to keep c l e a n due to i t s s m a l l e r d i a m e t e r . P resen t estimates wi th t h i s l e ss aggressive s trategy i n d i c a t e t ha t r a t e s of up to 10 meters/day of penetrat ion are poss ib le and that in 40 days approximately 200-250 meters can be d r i l l e d u s i n g h i g h v i s c o s i t y d r i l l i n g mud. Serocki c losed the.report by i n d i c a t i n g that the most d i f f i c u l t part of the program has been acocnplished.

583 WIRELINE LOGGING SERVICES OPERATOR REPORT

R. Anderson (L-DGO) reported that the Terralog Log Analys is System, placed on RESOLUTION d u r i n g e a r l y 1985, i s g i v i n g ve ry good r e s u l t s . When a p p l i e d t o Leg 103 d a t a , a seismogram was generated f rom the l o g g i n g da t a t ha t c o r r e l a t e d w i t h do lomi te " s t r i n g e r s " observed i n the l i t h o l o g i c data. Present ly , L-DGO i s inves t iga t ing poss ible solut ions to the prctolem of logging i n bad h o l e c o n d i t i o n s and problems a s s o c i a t e d w i t h the s w e l l i n g o f c lays using the f r e shwate r d r i l l i n g mud. The TAMU eng inee r ing group has been asked to invest igate ways i n which the problem of c l ay swel l ing can be eliminated or i t s e f f e c t s reduced. Anderson i n d i c a t e d that a second e d i t i o n of the ODP Logging Manual w i l l be published during 1986 which w i l l anphasize the s c i e n t i f i c uses f o r the t o o l s . The manual may a l s o be p u b l i s h e d i n the 1986 e d i t i o n of REVIEWS OF GEOPHYSICS. Anderson c l o s e d h i s i n t r o d u c t o r y remarks by s t a t i n g tha t an a d d i t i o n a l $140 K i s needed i n the L-DGO budget f o r the purchase of a second Borehole Te lev iewer (BHTV) and M u l t i - c h a n n e l Seianic (M::S) systan. He noted that the a v a i l a b i l i t y of backup too l s increases the success r a t e o f l o g g ing from 68% to 98%.

Leg 107 (Tyrrhenian Sea)

On Leg 107, logging analyses from the Terralog system w i l l be compared w i t h t ha t o f the Energy Systems l o g g i n g package. I n a d d i t i o n a C a l i f o r n i u m atomic source w i l l p l a c e d on the sh ip , p r i o r t o Leg 109, f o r use i n the n u c l e a r c o n b i n a t i o n t o o l . The nuc l ea r combina t ion t o o l w i l l be b u i l t i n to a sonde 95 f t . high and shou ld y i e l d i n f o r m a t i o n f o r c l a y t y p i n g , i n c l u d i n g t h e weight percent of aluminum.


The L-DGO Borehole Research Groap has lowered the p r i o r i t y o f thru-the-pipe logging due to p o t e n t i a l damage t p the s t r u c t u r a l i n t e g r i t y o f the d r i l l p i p e by hole condi t ions when not ro ta t ing

14

at the bottcxn of the hole. On Leg 108, a sidewall e n t r y sub (APPENDIX E) developed by IFP (France) w i l l be tested as an alternative to thru-the-pipe logging.

R. Ja r r a r d (L-D<30) also indicated that the co-chiefs now favor the inclusion of sonic and lithologic logs into the c r u i s e plan, i f clearance problens create more operations time. The Borehole Research Group estimates that logging at Sites MkUA, MAU 5 and SLR lA w i l l take 18 hrs./hole, with 11 hours devoted to the nuclear combination t o o l , 3 hours for hole preparation and 4 hours for the Long Spacing Sonic tool (I£S).

Because of t h i s request, Anderson asked guidance from the PCOM on whether, based on the uncertain logging workload, t o include a Schlumberger f i e l d engineer i n the logging party. The Downhole Measurenents Panel (DMP) favors logging on Leg 108 because of the p o t e n t i a l for clay typing, possible detection of climatic cycles and seismic stratigraphic c o r r e l a t i o n . The PCOM indicated that based on this new information, i t should probably rescind the dec i s i o n made at the October 1985 meeting. A new motion proposed by von Herzen (WHOI) and seconded by Kastner (SIO) was as follows:

PCOM Motion: The Planning Ccxnmittee requires that the Leg 108 co-chief s c i e n t i s t s conduct a standard logging package at the three p r i o r i t y sites (MAU 4, MAU 5 and SLR lA). Options exist for logging the other site s .


MCTibers of the L-DGO Borehole Research Group (R. Anderson, R. Jarrard and M. Zoback) held an evening seninar f o r PCOM members and guests to explain the detailed measurentaits and interpretations that can be made with the present logging instrumentation. This seminar was adjourned and w i l l be resumed during the May PCOM meeting.

responded that the question could be answered on a number of l e v e l s . However, the COSOD objectives could be best addressed by establishing a global suite of drillholes (4, possibly 6, holes) for long term observation and sampling.

Sediments and Ocean History Panel (SOHP)- APPENDIX G (presented by M. Arthur-URI)

Discussion:

Discussion centered on the SOHP recommendation to d r i l l a deep stratigraphic test hole in the Somali Basin as part of deep st r a t i g r a p h i c tests program. During this time the deep d r i l l i n g capabilities of RESCLUTICXI, with a r i s e r , were discussed and i t was g e n e r a l l y agreed that there i s a substantial amount of interest for a deep hole i n the Somali Basin. Discussion a l s o indicated that from the standpoint of engineering f e a s i b i l i t y a d d i t i o n a l d r i l l i n g techniques may have to be developed. In c l o s i n g discussion, the Science Operator suggested that as a prelude to riser d r i l l i n g , a deep hole (approx. 2000 m deep) may be needed.

585 REVIEW OF JOIDES SCIEMTIFIC ADVISORY STRUCTURE

The Planning Ccmmittee agreed that since the chairmen of the JOIDES Panels were i n attendance at t h i s meeting, i t would be appropriate and very useful to discuss potential restructuring of the JOIDES panels.

Discussion of the present structure indicated that frustration with t h i s systan has resulted i n the resignations of the LITHP chairman and the SOHP chairman. "Rie frustration was based on a general feeling among LnHP and SOHP chairmen that there i s an apparent lack of coordination between the panels, there i s an unnecessary duplication of e f f o r t among the panels, there i s a f e e l i n g that the advice of the thenoatic panels i s largely ignored i n favor of recommendations from the regional panels and that some d i s c i p l i n e s within the geologic oonmunity (especially geochemistry) are not represented in the present structure and are being o v e r l o o k e d . L a s t l y , there was a general f e e l i n g of a majority of the chairmen that panel l i a i s o n s presently have too many meetings to attend and this system i s not an effective means of communicating information.

It was suggested and agreed by both chairmen and PCOM that one of the main problems i s one of communication between the panels and with PCOM. One possible solution was that an exchange of ideas between the panels occur at an annual meeting fo r panel chairmen and through j o i n t panel meetings. These would p>rovide chairmen with an opportunity to i n t e r a c t and develop d r i l l i n g suggestions into a well defined and unified plan without diqplicat-i n g ideas or o b j e c t i v e s and to r e s o l v e d i f f e r e n c e s between panels. Another suggestion was that the panel l i a i s o n system be improved to more effectively disemtninate information among panels and PCOM. I t was a l s o recommended that the responsibilities of SOHP be broadened into a geochemistry panel, an ocean h i s t o r y -stratigraphy panel and a sediroaiteury processes panel i n order to address the concerns of the geochemical and s e d i m e n t o l o g i c communities.

Discussion a l s o indicated that most panel chairmen generally supported the present structure of thematic panels with support

17

fron regional panels. In addition, the group further emphasized that the d r i l l i n g program should be driven by the thematic problems addressed by COSOD.

The consensus of PCOM was that i t was premature to change the panel structure at th i s time although i t was recognized that there have been d i f f i c u l t i e s , especially i n terras of communications, between thanatic and regional panels. In view of t h i s s i t u a t i o n a better inter-panel liaison network i s required. One effective neans of achieving this w i l l be to esta b l i s h a meeting of the panel chairmen, to be held during the summer (in addition to the annual meeting with PCOM). A second means i s to have r e l e vant panels hold overlapping meetings i n order to resolve conf l i c t s an p r i o r i t i e s . The development of d r i l l i n g plans should be based on an identification, by the thematic panels, of the global thematic objectives which may be best attained i n any p a r t i c u l a r region. Regional panels should take these themes as the basis for regional d r i l l i n g plans and there should be a further evaluation by the thematic p a n e l s . At t h i s time the res o l u t i o n of any conflicting advice from the regional and thonatic panels should occur. The PCOM w i l l then construct a d r i l l i n g plan based on this flow of advice. PCOM further agreed that although the Program i s placed within a 10 y r . framework, i t should be emphasized that the boundary conditions are flexible. It was the general consensus that while thematic panels w i l l continue to receive propos a l s , regional panels w i l l concentrate on d e t a i l e d p r o p o s a l review i n the develc^ment of the regional plans.

PCOM agreed that COSOD-2 may provide an opportunity for a review and possibly re-alignment of the panel structure. Meanwhile, PCOM w i l l consider ways to best include the views of the geochemical community into the planning process.

The above consensus was acdiieved with the Panel chairmen and later confirmed by POOM. M. Purdy (LITHP) requested that h i s d i s agreement with the above consensus of the PCOM be reflected i n the minutes of the meeting.

586 SHORT-TERM PLANNING

Revisions to the 1986 Ship Schedule

L. Garrison (TAMU) indicated that the schedule (APPENDIX C) has been changed to include a transit leg (Leg 112T) between Legs 112 and 113 with a po r t c a l l i n Punta Arenas, Chile. Ttiis adjustment occurs because Ccdlao, Peru w i l l be used as a p o r t c a l l f o r Legs 111 and 112 due to the difference i n fuel ($76/ton i n Dec. 1985) which could potentially save the program $150 K.

Leg 108 (NW Africa)

18

No problens are anticipated f o r Leg 108 other than those caused by clearance d i f f i c u l t i e s . The addition of a heat flow progrcun has been discussed and okayed with TfiMJ and the co-chiefs and w i l l be implemented by the physical properties specialist on RESOLUTION. In addition, engineering tests on the minicore systean and the sidewall logging sub w i l l be conducted.

Leg 109 (MARK-2)

It was consensus of the Downhole Measurenents Panel (DMP-APPENDIX M) and the Lithosphere Panel (LITHP) that the h o l e established on Leg 106 be deepened with some logging conducted at the s i t e (Site 648 B) and f u l l s u i t e of logging at DSDP Hole 395A.

Discussion:

During discussion the questions arose of how much d r i l l i n g time i s estimated to achieve a depth of 300 m and what are the options i f d r i l l i n g i s slower than expected ( i . e . i s there a cut-off time and are there options to t r y other techniques such bare rock spud-in without the guidebase). TAMU respcmded that current estimates are that approximately 36 days are needed to reach an estimated depth of 250 m. I t was the consensus of the groc^ that deepening Site 648B i s the highest p r i o r i t y of Leg 109 and that goal should remain the primary objective. I f <^>tions exist, they should be along the l i n e s of attempting d i f f e r e n t ways of bare rock spud-in.

Add i t i o n a l discussion was held concerning the reoomendation by LITHP and IMP that logging be conducted as part of the s c i e n t i f i c objectives f o r Leg 109. Hie following motion was proposed by Rcînson and seconded by Kastner.

PCOM Motion: Recognizing that d r i l l i n g into zero age crust i s a major goal of the ODP, the highest p r i o r i t y o f Leg 109 i s the deepening of Hole 648B including the logging package as reooranend-ed by the Downhole Measurements Panel. If no substantial progress i n d r i l l i n g i s achieved a f t e r 30 days the ranainder of the time w i l l be spent logging Hole 395A and the f i n a l backup for t h i s l e g w i l l be t o d e f a u l t to the Kane F r a c t u r e Zone as the f i r s t p r i o r i t y .

Vote : 11 for, 3 against, 0 abstain

Discussion then focused on determining to what extent and to what depth the rubble zone may continue to impact on d r i l l i n g plans. I t was generally agreed that better seismic experimaits were needed i n order to make that determination. Hussong proposed, seconded by Shipley, the following motion:

19

PCOM Motion: The Planning Ccxnmittee recommends that Wireline Logging Services investigate the development of a downhole seismic program, to be conducted at an early stage i n Leg 109 and at various stages of d r i l l i n g , to determine the structure below the hole (including i d e n t i f i c a t i o n of rubble zones) at S i t e 648B using downhole geophysical techniques.


I t was f e l t by various menbers of the PCOM that the back-tp plan for Leg 109 be more detailed. After discussion, the following motion was proposed by von Herzen (WHOI) and seconded by Rcînson:

PCOM Motion: The PCOM recommends that the Lithosphere Panel's (LITHP) p r i o r i t y objectives for Leg 109 be accepted as the back-up plan with the understanding that Kane Fracture Zone objectives have a higher p r i o r i t y than the Snake P i t hydrothermal area and the logging at Hole 418.


Leg 110 (Barbados)

TAMU indicates that there are no problems and that progress continues on d r i l l - i n casing develqproait.

Leg 111

Discussion indicated that LITHP (APPENDIX F) supported the French hydrothermal program at EPR 13ON and that DMP (APPENDIX N) supported deepening DSDP Hole 504B. Some PCOM members indicated that possibly Leg 111 should be a return to further deepen S i t e 648B, i f Leg 109 was a great success. It was generally agreed by PCOM that deepening and logging Hole 504B i s a major goal of ODP and would complement the work done at S i t e 648B. The TAMU engineers indicated that better d r i l l bits w i l l be a v a i l a b l e and are confident that the hole can deepened an addi t i m a l 500 m. The following motion proposed by Robinson and seconded by Kastner:

PCOM Motion: Recognizing the importance of sampling the deep oceanic crust and the d i f f i c u l t i e s of bare rock d r i l l i n g on the East P a c i f i c Rise (EPR) at t h i s time, the PCOM reocmnends that Leg 111 be primeurily devoted to the deepening and logging of Hole 504B.


20

In discussing the option of using Leg 111 for the continued deepening of^ S i t e 648A and deferring deepening of Hole 504B to a late cruise i t was generally agreed that mp and LITHP should be asked to consider this option. In the meantime, Kastner proposed the following motion, which was seconded by Cadet :

PCOM Motion: At t h i s stage i n the planning process, the prime objective of Leg 111 i s the deepening of Hole 504B. Dependent on the r e s u l t s from Leg 109, i n terms of substantial d r i l l i n g progress and the downhole experiments, PCOM w i l l consult LITHP and DMP regarding a decision to replace d r i l l i n g at Hole 504B by a third leg devoted to Hole 648B.


The PCOM considered the logging program for the 504B program as proposed by DMP (APPENDIX N). M. Salisbury indicated that t h i s program i s s i m i l a r to that prqposed for Hole 395A but includes a Vertical Seismic Profiling experiment. Robinson proposed and Hus-song seconded the following moticxi:

PCOM Motion: The PCOM recommends that the logging program as suggested by the DMP be adopted, with the inclusion of a V e r t i c a l Seismic P r o f i l i n g (VSP) experiment, i n t o the downhole measurements program for Hole 504B.

Vote 15 for, 0 against, 0 abstain

N. P i s i a s (OSU) indicated that a reconnendation of SOHP was that a double APC program be undertaken at 504B to recover a reference sequence for the late Neogene-Quaternary section of the eastern Pacific (APPENDIX G). In considering the recommendation, PCOM agreed to the following:

PCOM Consensus: I t i s the consensus of the POOM that a maximvm of 5 days be included i n t o the primary objectives of Leg 111 for d r i l l i n g double APC and XCB s i t e s i n the v i c i n i t y of Hole 504B with one s i t e to be a representative ôchaaical s i t e , as proposed by Mottl, and the other i s to be a paleontological s i t e .

Co-Chief Scientists for Leg 111:

The PCOM recommended that, f o r Leg 111, the team of Becker (UM) and Sakai (Japan) be suggested to lAMU.


TAMU i n d i c a t e d that co-chiefs have been selected and no l o g i s t i c a l problems are expected. However, no s p e c i f i c d r i l l i n g program has been developed and problems with clearances have not yet been investigated. D. Hussong indicated that before a d e t a i l ed program can be developed the s i t e survey data needs to be

21

evaluated by SOHP, TBCP, CEPAC and the co-chiefs. It was agreed that further planning be deferred until the site survey information has been evaluated by TECP, CEPAC and SCHP.

Leg 113 (Weddell Sea)

A review indicated that excellent s i t e survey data exist for the leg provided that POLARSTERN achieves most of i t s c r u i s e objectives. H. Beiersdorf (FRG) indicated that due to severe ice conditions, PQLARSIEHN has only been able to c o l l e c t less than 400 km of multi-channel seismic data on i t s current cruise. SOP had proposed Kennett (URI) and Fuetterer (Polar Inst.-FRG) as co-chiefs and SOHP had concurred. T. Francis proposed P. Barker (UK) and H. Beiersdorf proposed K. Hinz (BRG, PRC). It was agreed that the co-chief scientists team should consist of one geophysi-c i s t and one sedimsitologist/paleooeanographer.

The following motion was proposed by Francis (UK), to resolve the staffing problem, and seconded by Shipley (UT):

PCOM Motion: The PCOM recOTtmends the team of Barker (UK) and Futterer(FRG) be suggested to TAMU as co-chief scientists f o r Leg 113.


Discussion of Leg 113 plans indicated that while the SSP was generedly satisfied with the s i t e survey data, i t has however, requested that a piston core be taken at Site W4 and that heat flow studies be conducted at Site WIO. TAMU indicated that W4 may be covered with pack ice during operations and a contingency for this s i t e i s needed. Garrison pointed out the need for an i c e picket vessel.

NSF estimated that an i c e picket boat can be cheurtered for approx. $700 K for 60 days and TMfHJ indicated that Requests for Proposals (RFP) w i l l be sent for bids. Discussion then focused on other ships that may available i n the Antarctic at less expensive p r i c e s . T. Francis suggested that a B r i t i s h vessel may be a v a i l able.

TAMU a l s o indicated that problems exist for the Weddell Sea objectives of the SOP as ac^roved by POGM. These problems center on the development of a d e t a i l e d c r u i s e plan i n a 7 month time frame and the i n c l u s i o n of logging i n t o the science plan. In considering an a l t e r n a t i v e f o r W4 i t was the consensus of PCOM that, since WIO has a high SOP rating as an alternative, does not appear to have safety problems and appears to be predominantly ice-free at the time of the c r u i s e , WIO be a contingency to W4 and further the POOM agreed that the logging program suggested by DMP for Leg 113 be included into the general science plan.

22

Leg 114 (Atlantic Sub-Antarctic)

It was noted that NSF has funded J . LaBreque to carry out si t e surveys using the. R/V POIAR DUKE in Sept-Oct. 1986.

PCOM agreed to recommend that the Science Operator choose co-chiefs for t h i s leg from SOP and SOHP recommendations (P. C i e s i e l s k i - Univ. of F l a . and J . LaBreque- L-DQO) together with the unsuccessful names from Leg 113. Other possible names suggested were K. Hsu, J . Behrandt (USGS), B. Tucholke (WHOI), R. Stein (on DSDP Leg 91).

587 MEDIUM RANGE PLANNING (INDIAN OCEAN 1987/88)

Review of proposed d r i l l i n g i n the Indian Ocean:

Southwest Indian Ridge (SMIR)

There was discussion of the s c i e n t i f i c objectives of SWIR d r i l l ing including the optimum alignment of holes and the d i f f i c u l t i e s of conducting oblique seismic experiments (OSE) i n SWIR. It was noted that this leg i s dependent on s i t e surveys being obtained. PCOM considered plans for the Indian Ocean i n light of the above reviews and noted that i t i s NSF p o l i c y to devote s i t e survey funds ( i n FY 87) to West P a c i f i c targets. NSF stated that, i n EY87, there are unlikely to be any a d d i t i o n a l funds f o r Indian Ocean s i t e surveys as the NSF p r i o r i t y i s f o r West P a c i f i c surveys. Funds for FY86 appear to be f u l l y committed. To be succ e s s f u l , at this stage, our Indian Ocean s i t e survey program must be highly ocmpetitive, i n s c i e n t i f i c terms, with proposals f o r the West Pacific.

Neogene Package

In discussing the Neogene Package, as prqposed by W. P r e l l (Brown Univ.) and included i n the lOP program, i t was the consensus of PCOM to approve the program as proposed with the caveat that the d r i l l i n g program may require more than 1 l e g . Detailed planning i s dependent on s i t e surveys, to be conducted by P r e l l , with GLORIA data on the d i s t a l Indus Fan being done by Kidd (lOS).

Mascarene Basin/ F o s s i l Ridges

PCOM Motion: In view of the impossibility of obtaining s i t e surveys for t h i s l e g , the Planning Committee recommends that the Mascarene BasiiVFossll Ridges program be eliminated from the planning schedule.

Proposed by Robinson and seconded by Hcxmorez.

23


Red Sea Program

After discussing the program suggested by the Red Sea Working Graop, i t was the consensus of the POOM to accept the proposed s c i e n t i f i c program, with the following change: Site IB in the Nereus Deep should be a single b i t hole with no re-entry.

It was noted that France was obliged to pospone a si t e survey program using SURDIT and that there could be p o l i t i c a l problens i n obtaining clearances and safeguarding the ship i n the Red Sea.

Kerguelen-Antarctic Margin (Prydz Bay) Program

The PCOM re i t e r a t e d i t s October 1985 decision that the ship schedule be arranged around a normal port stop, r a t h e r than changing the ship's crew at Kerguelen, because of the extra costs involved (approx. $800 K). The POM asked TAMU to develop and present at the next meeting a straw schedule with the Prydz Bay program and intetrmediate p o r t c a l l s at Reunion or Mauritius I s . included. The PCOM agreed that Prydz Bay c^jectives (endorsed by SOP and SOHP) and the t e c t o n i c basement o b j e c t i v e s i n N. Kerguelen (proposed by lOP and TBCP) are the highest p r i o r i t i e s for these two legs.

Broken Ridge/90OEast Ridge

D i f f i c u l t i e s i n obtaining s i t e surveys for 90°E ridge were noted. PCOM accepted the p r i o r i t i e s f o r t h i s l e g as proposed by lOP and SOHP. The PCOM requested that T. Francis (UK) obtain and present at the next meeting a schedule f o r DARWIN. F r a n c i s indicated during discussion that DARWIN may be available for s i t e survey operations or 90^. It was also the consensus of PCOM that the Broken Ridge program be endorsed as proposed.

Intraplate Deformation Program

PCOM endorsed the program as prqposed with some reservations on the science, specificsdly the o r i g i n of upward flow of water i n surface tenîerature-dqpth profiles and the a b i l i t y to date the onset of deformation. The program was re f e r r e d to TECP and lOP for further ocmment. TAMU also suggested that the seismic data be examined by PPSP.

Argo-Exmouth

The PCOM generally approved the proposed plan but expressed concern that the use/success of a re-entry cone i n the proposed program be assessed by the Science Operator, DMP and the proponents. This ooncem was e ^ e s s e d as the Argo/Exmouth program i s one of the highest p r i o r i t i e s of the eastern Indian Ocean and

24

that, as currently planned, there may be insufficient time i n one leg to oorplete the prime objectives.

Rodriguez Ridge/Mascarene Plateau and Otway Basin Programs

These programs have been proposed as additional legs by lOP. The POOM agreed that the previously discussed programs are more s c i e n t i f i c a l l y interesting legs and have a much higher p r i o r i t y . Sane doubts were expressed as to the s c i e n t i f i c merit of Otway Basin margin d r i l l i n g . POOM agreed not to include these prcîosals in the Indian Ocean program at this stage.

In planning the Indian Ocean program, i t was the consensus of the POOM to devise potential alternate legs for SWIR due to potent i a l s i t e survey problems and for Red Sea d r i l l i n g to avoid potentially unsolvable p o l i t i c a l problems. The alte r n a t i v e s that were presented were an add i t i o n a l Neogene package leg, a deep stratigra£diic hole i n the Somali basin and 1 leg dedicated to the Makran. A f t e r discussing these options, the PCOM voted on the following motion as proposed by Robinson emd seconded by Keustner:

PCOM Motion: The PCOM requests that lOP, TBCP and SOHP consider alternatives for the Indieui Ocean D r i l l i n g program and that they do t h i s with a view that the Indian Ocean might be exited sooner than originally planned. Specifically, lECP should consider SWIR vs. Makran and SOHP should consider the additional Neogene leg vs. a Somali deephole.


TAMU requested that PCOM develop a f i r s t - o r d e r ranking of SWIR and Red Sea alternatives at this meeting so that ship planning may begin. In responding to t h i s request, POOM passed the following motion, proposed by Robinson and seconded by Honnorez:

PCOM Motion: I f Southwest Indian Ridge and the Red Sea programs are eliminated from Indian Ocean planning a c t i v i t i e s , the next p r i o r i t y f o r the f i r s t l e g i n the Indian Ocean w i l l be the Neogene Package.


588 LONG-TERM PLANNING (PACIFIC OCEAN 1989- )

Overall Time i n the P a c i f i c Ocean

I t was suggested that the time of circvinnavigation, as suggested by COSOD, imposes an unnecessary oontraint that should be removed. T h i s a c t i o n , i t was fu r t h e r suggested, would allow the s c i e n t i f i c objectivesto constrain the amount of time i n the area. I t was the consensus of the POOM that the panels (WPAC, CEPAC and

25

thematics) should develop 31ists of objectives/thenes/priorities (short range, medium range andlong range) developed i n 1, 1 1/2 and 2 year time frames forthe P a c i f i c . I t was agreed that i t i s essential for the chairmen of the thematic panels, the Pacific regional panels, SSP and DMP to meet p r i o r to the May PCOM to l i a i s e on Pacific planning problems. Discussion was closed by the following motion, proposed by Hayes and seconded by Beiersdorf:

PCOM Motion: WPAC, CEPAC, SOP and the thenatic panels should develop a s c i e n t i f i c program for the P a c i f i c Ocean under the i n i t i a l time constraint of a total of three years for this entire region with the time being partitioned a^ôximately equally between the western Pacific (the general area mandated to WPAC) and the ranainder of the P a c i f i c (including the Bering Sea and f a r Southern P a c i f i c ) . This time constraint and i t s d i v i s i o n are tentative and subject to revision i n consideration of subsequent sc i e n t i f i c arguments from the panels.


589 PANEL MEMBERSHIP

Panel Rotations

I t was the consensus of PCOM that the panels should propose a rotation scheme for membership (noting that non-US members are not r e q u i r e d to adhere to the rotation) and should suggest possible replacenents and additions to ensure as complete a d i s c i p l i n a r y cover as possible. PCOM w i l l decide on rotations and new membership at i t s May meeting following the above input from the panels.

Panel Chairmanships

PCOM agreed to the following names:

SOHP- R. Garrison (UC-Santa Cruz) L. Mayer (Dalhousie Univ.)

LITHP- D. Walker (L-DGO) A. Saunders (Leicester Univ.) J. Sinton- (Hawaii) R. Detrick- (URI) K. Macdonald- (UCSB)

The PCOM Chairman w i l l appoint new chairmei from the above l i s t s according to a v a i l a b i l i t y and i n discu s s i o n with appropriate PCOM members.

PCOM Liaisons

26

The following changes in PCOH/panels liaisons were made:

TBCP- add P.Robinson (Canada)

SSP- N. Pisias (OSU) replaces P. Robinson T. Francis (UK) replace H, Beiersdorf

TEDCOM- T. Francis replaces M. Kastner (SIO)

Panel Chairmai's Meeting PCOM agreed to appoint D. Rea (CEPAC) as chairman of this

group. It was agreed that the meeting would be held at OSU prior to the next POOM meeting. Subjects suggested for the agenda were: global review of thematic objectives of ODP; panel-panel and panel-PCOM ccxnmunications and improvements to working methods; resolution of Indian Ocean planning conflicts; identification of major objectives of Pacific Ocean drilling; input of geochemical advice; site survey and downhole measurements input.

590 ANY OTHER BUSINESS

Rotation of the JOIDES Office

PCOM was informed that the JOIDES Office w i l l rotate to Oregon State University as of 31 Septanber 1986 and that OSU w i l l be succeeded, in 1988, by the Hawaii Inst, of Geophysics. The non-US members of JOIDES were asked to submit recommendations (with f i n a l decisions made by the 5 non-US EXDOM members) for the non-US administrative position in the JOIDES office. With this rotation, D. Caldwell will succeed J. Knauss as the EXOOM chairman and N. Pisias will succeed R. Larson as the PCOM Chairman.

Meeting Schedule

28-30 May 1986 at L-DGO, Palisades, N.Y.

11-15 August 1986 Corner Brook, Newfoundland, Canada

POOM Chairman Absence in March-^ril

R. Larson informed the PCOM that he would be on a cruise to the Exmouth Plateau are during March-^^ril 1986. In his absense, he proposed that H. Beiersdorf act as Chairman until 20 March 1986 and that J. Honnorez hold the post u n t i l 10 A p r i l 1986. Panel meeting approval and proposals will be handled by T. Mayer (JOIDES Office). The POOM agreed to these aurrangemaits.

Lead Time in Planning

27

D. Heinrichs (NSF) enphasized that the PCOM should include 1-2 additional years of planning (beginning with the Western Pacific program) into i t s process at this stage i n order to give more focused, concise planning advice to NSF, JOI and EXCOM to enable draft budgets to be prepared. During discussion, H. Beiersdorf expressed his strong dissatisfaction with the i n i t i a l phases of Indian Ocean planning. R. Larson i n d i c a t e d t hat Western P a c i f i c planning may be as d i f f i c u l t as that for the Indian Ocean Program but he was confident that a genered. d r i l l i n g program w i l l be develc^jed by August 1986.

In c l o s i n g discussion, the PCOM asked how i t could interact with JOI and NSF i n order to have sane input into fund a l l o c a tions and what the deadline was for making constructive suggestions to the program plan for the upcoming year. Heinrichs responded by indicating that i n the short term, suggestions could be made at the May 1986 FOOM meeting and that i n the long term, suggestions can be made by October of any given year. Heinrichs closed by emphasizing that a program for the western P a c i f i c must be devel<^)ed by October 1986.

COSOD-2

In responding to a mandate by the EXCOM, given at i t s Jan. 1986 meeting, the POGM prepared a draft Terms of Reference for a COSOD-2meeting (APPEMDIX S). Offers to host the meeting were made by T. Francis (for Oxford or Ceonbridge, England) and by H. Beiersdorf and J-P. Cadet (for Strasbourg, France). The location w i l l be finalized at the May PCGM meeting. Tlie steering caamittee w i l l c o n sist of 12 members with one member from each of the non-US members plus a chairman. The non-US members were encouraged to confer with their national coimittees for naninations for membership and US members were asked to consider nominations. In addit i o n USSAC w i l l be asked to serve as a US nominating committee. POOM w i l l make the f i n a l s e l e c t i o n s . I t was suggested that the manbership be a mixture of people within and outside of ODP. However, a majority of the membership w i l l c o n s i s t of those people f a m i l i a r with ODP. Discussion of the Chairmanship was deferred u n t i l the May PCOM. The meeting w i l l be funded by co-mingled funds with travel to be a national responsibility.

the PCOM thanked M. Kastner f o r hosting the meeting and arranging the f i e l d t r i p . J . Winterer was thanked for acting as the f i e l d guide. W. Nierenberg was thanked for hosting a reception for the POOM and R. Anderson, M. 2toback and R. Jarrard (Wirel i n e Services Contractor) were thanked for the logging seminar. The meeting was adjourned.

TO: Roger Larson, Chairman, PCOM FM: Donald M. Hussong "^^/l RE: Report on meeting of Ad Hoe coanittee on ODP downhole packer

capabilities and plans

A group consisting of Keir Becker, Mike Stoms, Dave Huey, Glenn Foss, Dan Moos (substituting for Roger Anderson) and I met at the DSDP offices i n La J o l l a on 15 Novenber 1985. At the request of POOM we discussed the following topics:

1) the TAM packer that Kelr Becker i s developing for Leg 109 and later,

2) the TAM packer to be b u i l t with design Input from ODP engineers for Leg 110 and later, and

3) the wireline packer under consideration by the L-DGO logging group.

The results of our discussion can be sunnarlzed as follows: 1) Bceif r fMcifgr- Kler Becker*s packer, which i s being supported

by funding outside t t e ODP project, i s a straddle packer (2 seals that can be separated by a chosen amount of d r i l l string) that was tri e d on Leg 102 but faUed due to a ninor flaw. This packer i s being modified at TAM (the manufacturer) and Bscker i s confident i t w i l l be ready and tested for Legs 109* 110* l l l f and subsequent legs [ f i n a l testing i s scheduled for the week of 13 January 1986, so may already be conplete]. Becker i s personally prepared to ride the d r i l l s h i p to provide support for i t s use on Legs 109, 110, and/or 111.

Becker's packer cannot be in the d r i l l string during d r i l l i n g , and as presently planned oust be placed above the bumper subs i f used in d r i l l i n g because i t cannot take a substantial ccnpressive load. There i s sone hope that with good heave caqwnsation t h i s packer could be placed just above the b i t in the future. Logging and coring can be done through thi s packer, although u n t i l i t can rotated i t must be used with a reentry cone.

Dr. Roger L. Larson (January 10, 1986) - 2

It should be possible to modify this packer so that a pipe connecting the two inflatable seals that i s now external to the d r i l l pipe between the packer subs i s replaced by a modified pipe with an internal vent. This modification should allow rotation. The question would then ronain i f this packer can be placed below the bumper subs during d r i l l i n g . The packer might be strengthened by using a larger mandrel and top control sub. There are presently no plans to make the modifications to allow rotation or location near the d r i l l b i t .

The Becker packer has the advantages of being able to straddle a formation and also of not applying pressure to e d r i l l string when the straddled area i s pressurized.

fCuster pressure recorders monitor differences i n pressure between the two sides of both of Becker's packers.

Becker presently has the necessary funding to buy a flow meter ^ to f i t i n the d r i l l string on the packer sub so that the rate of flow i n or out of the packer can be measured.

This packer i s presently able to operate i n temperatures up to 100-125 Cf and seals are available Urnt can readily convert i t for operation at temperatures up to 200 C with available funds.

2) CffiP/TAM packer. TAM i s also building a new single-element packer for ODP that w i l l be ready for use on Leg 110. This packer can be rotated and f i t s i n the string as close as 10 m above the b i t . I t i s clean inside, so coring and logging can occur through i t . This packer presently has an 8.5 inch diameter, so i s wider than the rest of d r i l l string (8.25 inches above the b i t ) . OD? engineers at TANJ are presently Investigating reducing the outside diameter of th i s tool so that i t w i l l not be a "knuckle" in the d r i l l string.

Cost of the ODP/TAN packer w i l l be approxlnately $25»000 for the f i r s t tool and approximately $15fOOO for later duplicates. There w i l l be at least one of these ODP/TAM packers available for Leg 110; they hope that i f funds are available two of these tools w i l l be available for 110.

Becker w i l l provide a Kuster pressure recorder for use with the ODP/TAN tool vhen needed as long as he has one available.

3) wirgHna packer. At the tloe of our meeting the development of t h i s tool was on hold. The o r i g i n a l plan had been that AMOCO was to build a prototype of their design, test i t , and then help the ODP logging group to modify a sllm-llne version for ODP use. AMOCO has lo s t interest In building their prototype because of o i l patch econcnlcs.

The design concept Is to have a wireline lowered system that can i n f l a t e with a dounhole e l e c t r i c motor/pump to seal a 12 (plus) inch d r i l l hole. The tool would be a straddle packer that has four large sample chambers that are f i l l e d with f l u i d sucked from the formation between the packers (this would constitute a permeability t e s t ) . The tool requires


downhole real time sensors to indicate when water flushing through the tool i s actually from the formation. This i s a conqjlex tool, ljut» the ODP Wireline Services Group at L-DGO has $140K set aside with Mark Zoback at Stanford for f i n a l design, construction, and testing of such a device. This development, woric has not been pursued because i t i s the understanding of the L-DGO logging group that PCOM considers actual building of a tool to be outside their charge. I t seemed to the participants at this meeting that $140,000 should be adequate for the L-DGO logging group and Zoback to build, with a consultant or sub-contractor where necessary, a wireline packer on the AMOCO concept that could be available in one year. Moos w i l l check on the details of what directives PCOM should, give the Wireline Services Group at L-DGO that would make them comfortable to proceed with the construction of their own tool.

There was to be a meeting with AMOCO in Tulsa Just before Christmas with the L-DGO logging group, TAMU engineers, and TAM engineers to discuss the possibility of AMOCO releasing some of their design plans to OD? and TAM so that they could proceed with building some form of wireline packer. I f successful, the OD? funding now in reserve with Zoback could go to Tam so that they could build (possibly with the addition of supplementary funds of their own) a wireline packer for ODP, I t i s the goal of the L-DGO group that 3 tools are eventually b u i l t to provide necessary backup for operational use. I f these planned discussions with TAM are unsuccessful, the next steps would have to be to issue RFP's for wireline packer development, or go to other con?>anies (potentially including foreign companies) with plans similar to those presented to TAM, or to give further consideration to having a tool b u i l t at L-DGO.

[Subsequent to I n i t i a l preparation of this meeting report, preliminary agreements have been reached by TAM, OD? engineers, the L-DGO logging group, and (I presume) AMOCO, to build a compromise version of a wireline packer which w i l l f i t on the end of the d r i l l string and be operated using the logging wire and a side-wall sampling device. This tool w i l l apparently perform many of the functions desired from a wireline packer, but w i l l require a pipe t r i p (and thus a re-«ntry cone) to operate.]

I t i s clear that PCOM oust decide what kinds of packers are desired in the near future, and whether or not a wireline packer that s t i l l requires a pipe t r i p satisfactory and worth development. Keir Becker i s preparing a more detailed description of his packer t o o l , as well as other options, for presentation to the POOM at the January 1986 meeting.

Other point ft t/iat. r i m up at the BWting that dby be PBrtlnent;

Ross Barnes has outside funds to byild a pore water sample for use with an APC. He may be interested i n modifications to use this device with larger volume sanq>ling chambers i n a packer.


Ures Giesdce (SIO) has an outside proposal (not yet funded?) to put a string of large ("1 l i t e r ) sample bottles down a hole on Leg 110.

The old Lynes f l u i d sample bottles are s t i l l around and should be okay to adapt to sample in a TAM packer. The rest of the Lynes packer i s considered useless and i s to be surplussed.

The pressure core barrel can be refurbished and be ready for use by Leg 112 i f the ODP engineers are so directed. They should be informed to do this by the time of the January PCOM to expedite their scheduling; i f they are not informed by the time of the May PCOM i t w i l l be too late.

JOIDES Lithosphere Panel Annual Summary for 1985

MARK D r i l l i n g APPENDIX F DEC 2 3 1985

To begin on a positive note, i t i s clear that this was the highlight of the year. The exceptionally high quality s i t e survey work in the MAHK area, the successful planning for this leg capped by the trouble-free f i r s t bare rock guidebase emplacement were a l l a promising start to this f i r s t high p r i o r i t y lithosphere leg. The slow d r i l l i n g problems are s t i l l being assessed as t h i s i s being written and cannot be commented upon here.

2. EPR D r i l l i n g

EPR d r i l l i n g s i t e should have three characteristics: seismically defined magma chamber, f u l l photo coverage, and active hydrothermal a c t i v i t y but locate f i r s t s i t e i n downflcw zone i n order to minimize high temperature problons. Consensus was 'French* 13?N area probably best meets these requirements. However, l i m i t a t i o n of only two guidebases made EPR d r i l l i n g questionable and t h i s awaits planning decisions on 109 and review of 106 before progress can be made. Strong panel support exists for 'having a go' at hydrothermal d r i l l i n g so technical d i f f i c u l t i e s can be assessed early in the program.

3. 504B

The Panel considers the deepening of 504B to be an essential part of the f i r s t two years of d r i l l i n g . To emphasize the p r i o r i t y placed on this a formal d r i l l i n g proposal was submitted on behalf of the Panel. 4. Bare Rock Guidebases

The lack of funds for more than two guidebases was a dismaying occurrence: that planning for such a high p r i o r i t y d r i l l i n g target should be dominated by funding concerns so early i n the program was a source of considerable concern to Panel Members.

5. Indian Ocean

Many active discussions and careful proposal reviews led to setting our f i r s t four Indian Ocean p r i o r i t i e s as: 1. Red Sea, 2. 90E Ridge, 3. Aus-Ant. Discordance, and 4. SW Indian Ridge fracture zone. However, again i t must be stated that these are LITHP's p r i o r i t i e s only WITHIN the Indian ; Ocean. The Panel considers back-arc spreading center d r i l l i n g i n the Western P a c i f i c to be a higher p r i o r i t y than a l l of the above projects.

6. Western P a c i f i c

Planning for t h i s i s i n early stages but got o f f to an excellent s t a r t with Jim Hawkin's successful workshop. Proposals t o t a l l i n g almost s i x inches of double-sided xeroxes have recently been mailed to Panel Menibers: some concern e x i s t s as to whether such a volume of text can be reviewed adequately given e x i s t i n g procedures.

7. Lithosphere D r i l l i n g within ODP

Planning i s s u f f i c i e n t l y well-advanced that i t seems clear that LITHP's number one objective - c r u s t a l generation and magma processes - w i l l receive only three legs worth of e f f o r t during the f i r s t four years of the d r i l l i n g program. The Panel repeatedly expresses i t s f r u s t r a t i o n at t h i s ; and at i t s perception that ODP i s not adopting the philosophies of COSOD; and a t i t s concerns that the valuable and very l i m i t e d d r i l l ship resource i s being used as a g l o b a l l y wandering miscellaneous problem solver.

EXECUTIVE SUMMARY n | JOIDES SEDIMENTS AND OCEAN HISTORY PAPÊL

ACTIVITIES, 1985 APPEWD/X G

1) MEETINGS ^ h : -:r: - •• -The SOHP met twice in 1985, the first in Cambridge, U.K., Feb. 21-23 and the second at

LOGO. PaHsades, N.Y., July 75-l'S\ we met a third time on Jan.6-7,1986 at SIO,Xa Jolla, CA. 2) PANEL MEMBERSHIP

A) In the event that new member countries are not added, we recommended the following people to serve as members of SOHP, filling critical subject areas left vacant as the result of the withdrawal of our ESF and UK colleagues:

1. ) R.E. Garrison, UCSC; carbonate and silica diagenesis, sedimentary processes, (alternate: Pierre Biscaye, LEXXD: clay mineralogy, sedimentary processes)

2. ) John Barron (USGS; diatom biostratigraphy-Pacific paleoceanography) (alternate: R.C. Thunell, Univ. South Carolina; foraminiferal biostrat-paleoceanography)

B) Assuming that JOIDES panel structure remains the same, we have also recommended formal liaison between SOHP arid several regional panels as follows (liaison was lost due to several resignations):

1) P. Meyers to ARP (replaces Sarg) 2) R. Sarg to WPAC (replaces Shackleton) 3) L. Tauxe wants to be replaced on lOP (replace with L. Mayer) C) M. Arthur has resigned as SOHP Chairperson; SOHP nominates R.E. Garrison for the

new Chairperson (with Wolfgiang R Berger and Larry Mayer as alternates). 3) TECHNOLOGICAL DEVELOPMENTS

We continue to recommend as highest priority (approximate cnder of priority) the following technological improvements and/or acquisition and deployment of equipment already available for ODP: A) TECHNOLOGY

1. Heave compensation for the APC system (developed and tested on ODP Leg 105). 2. Drastic need for technology to avoid or moderate unstable hole conditions and to improve

ability to drill and recover fractured rock; should include mud technology for conditioning holes-necessaiy for deep penetration and drilling in accretionary prisms, etc.

3. A core-catcher system that would improve recovery in friable formations such as sand (recognizing that drilling in such formations is also a challenge).

4. Improved bits and drilling techniques that would allow better penetration and recovery in sequences characterized by pronounced lithologic contrasts (e.g., chert-chalk sequences that will be encountered frequently in the Pacific program).

s. Improved core liners (shattered or twisted during APC coring; is this quality control problem?)

6. Further improvement and routine availability of pressure core-barrel and in situ pore-water sampler to take advantage of unanticipated geochemical anomalies (gas-hydrates, salinity-alkalinity gradients, etc.). B) CORE HANDLING AND ARCHIVTNn

1. Improve color core photography, including routine deployment of continuous strip photography (using Tom Chase system as deployed on DSDP Leg 64).

2. Digital color record acquisition for s i ^ a l processing and permanent archive. 4) LONG-RANGE PLANS-RISER TARGETS

We were asked to consider our high-priority plans for riser drilling in 1992 or later should the riser system be deployed (assuming 1800m depth limitation); these arie:

1. Penetration, dating and characterization of major evaporite sequences, including the upper Miocene of the Mediterranean, the Miocene of the Red Sea and the lower Cretaceous of the South Atlantic-these are important for global geochemical mass balances, paleoclimate, hydrocarbon source bed and other considerations.

2. Penetration and recoveiy of gas hydrates and other gassy sediments such as in the Sea of Japan, Black Sea, Sea of Okhotsk and Cariaco Trench.

3. Penetration of continental slope structures and sequences, such as in the Niger Delta, the Gulf of Mexico, and offshore Northwest Africa.

4, Deeper riser drilling capability would significantly expand both the number of riser targets and their scientific attractiveness (SOOOm water depth).

5) MAJOR THEMES SOHP continued to endorse and develop scientific ocean drilling for the first 3 years of ODP

designed around the following major, high-priority themes: 1. Neoêne-OuatemaTv hiph-resolution sealevel. paleocliTnatic. hio-magneto-

chemostratigraphic records, global oceanic fluxes (carbonate, organic carbon. ttcX and land-sea interactions (Norwegian Sea; Baffin Bay-Labrador Sea; Northwest Africa; western Mediterranean; Peru margin; Weddell Sea and southern South Atlantic traverse; Kerguelan Plateau; Somalia and Oman margin; Mascarene-Chagos-Laccadive).

2. rnetaceous-Neogene hiph-latitude paleoceanofraphv-paleoclimatologv and biotic evolution (Norwegian Sea; Baffin Bay-Labrador Sea; Weddell Sea and southern South Atlantic; Kerguelan Plateau-Amery margin).

3. Mesgzpic-Ccnpzpic sea level changes, seismic stratigraphy, maior global uncppfomvties and global mass balances- deep stratigraphic tests (Moroccan Basin; SomaU Basin; Exmouth-Argo Abyssal Plain). This is one of our miyor themes for the entire PROGRAM! Detailed proposal for additional sites is available. 6) SPECIFIC RECOMMENDATIONS / PRIORTTIZATION OF REGIONAL DRILLING TARGETS _

SOHP ranked individual sites within PCOM-approved drilling legs of major interest to SOHP^^ and prioritized speciHc legs within regional drilling programs. The specific prioritizations and rationale can be found in our minutes; only a listing is supplied here"*:

D. Hole 504B (revisited; Leg 111 ?): urge double-APC coring of pelagic section-beautiful eastern Pacific late Neogene-Quatemaiy sequence.

E. Peru Margin (Leg 112): Strongly endorse 5-site depth and lateral transect of margin in Lima Basin for fluctuations in climate, productivity, oxygen-minimum zone, accumulation rates, and study of dolomite and phosphorite problems.(Recommend E. Suess, L. Kulm as co-chiefs).

F. Weddell Sea (Leg 113): l.)Wl, 2.)W2,3.)W4,4.)W5,5.)W10,6.)W6,7.)W7, 8.)W8. (Recommend J. Kennett and D. Futterer as co-chiefs).

G. South Adantic Traverse (Leg 114-ranks second priority to W1,W2,W4,W5 in Weddell Sea and S. Kerguelan-Ameiy objectives):( ranking sites in order SA-8, SA-2, SA-3, SA-5W). TOIAN OCEAN PROGRAM

1. Southern Kerguelan Plateau-Amery margin (high latitude paleoclimates-paleoceanography with Amery margin highest priority)(4 sites Piydz Bay; Kl-4 and KHP7,12, S.Kerguel. Plateau)

2. Oman margin-Owen Ridge-Somali margin-Indus Cone (with Oman-Owen Ridge highest priority)(ca. 5 sites, monsoon paleoclimate-upwelling-human evolution-Himalaya tectonics)

3. Somali Basin deep strarigrcphic test (near anomaly M-2S; 1 site)-part of deep stratigraphic tests program (ca. 2500m-multiple objectives incl.Tethys connections, black shales, African uplift)

4. Northern Kerguelan Plateau-southeast Indian Ridge transect (3 sites for Paleogene-Neogene paleoclimate transect-high latitude carbonate record: KHP3,1, S8B)

5. Exmouth Plateau-Argo Abyssal Plain (passive margin sequence to oldest Jurassic crust)(2 sites; EP-5 or possibly EP-2 and AAP-1; seismic straL important, conjugate to Somali deep hole)

6. Mascarene- Chagos- Laccadive (latitudinal-paleodepth transect)(6-8 sites) (RedSea)-if ship goes there, recommend APC coring on flanks of ridge for hydrothermal

sediments and site for paleoenvironment of sapropel sequence and evaporite-normal marine sediment sequence. Reconunend waiting for Red Sea with riser/BOP and high-T tools. "WESTERN" PACIHC PROGRAM

SOHP targets/objectives of high interest are (tentative ranking): 1.) Great Barrier Reef-Queensland Plateau transect, 2.)Japan Sea (Yamato Rise sites 1 and 3, Toyama Fan), 3.)Bonin transect (Sites C-F),4.)Sulu Sea (inner basin), 5.)S. China Sea (old crust)

SUBJECT: Executive Summary of 1985 A c t i v i t i e s of the Tectonics Panel

1) CHAIRMANSHIP I stood i n for Jeremy Leggett (UK) at our March meeting and was formally named Chairman i n A p r i l .

2) MARCH MEETINC AT LAMONT Most of the meeting, was devoted to a review, discussion, and ranking of d r i l l i n g proposals i n the Indian Ocean and Southern Oceans. Our procedures were l a r g e l y those established at our September 1984 meeting i n London. We had divided the oceans geographically and assigned a watchdog to each region. In March, each watchdog systematically summarized the thematic problems i n h i s region and how extant d r i l l i n g proposals would address them. We a l s o heard a report from the chairman of the Red Sea Working Group ( J . Cochran). We then p r i o r i t i z e d 10 and SO t a r g e t s u s i n g the voting system we devised i n London: 0 (lowest) to 10 (highest). Our top four p r i o r i t i e s were: Makran a c c r e t i o n a r y prism and slope basins ( 1 ) ; Indian Ocean i n t r a p l a t e deformation and f l u i d flow (2); SW Indian Ocean Ridge fracture zone ( t i e for 3); Bengal-Indus fans ( t i e for 3).

3) OCTOBER MEETING AT OCEAN RESEARCH INSTITUTE, TOKYO

a) Leg 110 Barbados Ridge: We recommended expending every e f f o r t Co d r i l l through the decollement at LAF-1 and then proceeding upslope to d r i l l LAF-2 and 3 if. time permits.

b) I n d i a n Ocean d r i l l i n g : We reversed our March ranking and chose SW Indian Ridge fracture zone over Makran as our top p r i o r i t y on the menu for May-June 1987. We also i n s i s t e d that basement be sampled on a l l parts (north, c e n t r a l , and south) of the Kerguelen plateau.

c) Western P a c i f i c : P r i o r to the meeting, I distributed copies of a l l ex i s t i n g proposals to each p a n e l i s t . I n Tokyo, the watchdogs ve appointed i n March reviewed the d r i l l i n g proposals for each region. We began t h i s review i n preparation f o r a formal ranking i n Spring 1986 along the lines of our March 1985 p r i o r i t i z a t i o n o£ Indian Ocean proposals. However, we decided i n s t e a d t o i d e n t i f y those prime g l o b a l thematic problems that can best be studied i n the Western P a c i f i c . In the future, we w i l l c r i t i c a l l y evaluate the: proposals that address these problems, and at our February 1986 meeting we w i l l prepare s p e c i f i c d r i l l i n g plans focused on our thematic o b j e c t i v e s : i ) The e v o l u t i o n of arcs and f o r e - a r c basement; i i ) The o r i g i n of back-arc basins; and i i i ) The tectonics of c o l l i s i o n s .

4) TECP PHILOSOPHY We have evolved from a reactive panel that simply ranked a l l proposals i n a reg i o n according to t h e i r thematic content, to one that w i l l independently advocate a Western P a c i f i c d r i l l i n g program focused on what we view as the key thematic problems i n the region.

r.»e 103 - G a l i c i a

In conclusion, ARP reiterates i t s recommendations on leg 103 d r i l l i n g that site 4b be d r i l l e d approximately one half to one kilometer east of i t s location i n "S c i e n t i f i c prospectus N°3"j this w i l l assure that the oldest and most complete section of synrift sediments which lap westward onto the pr e - r i f t sediments, w i l l be d r i l l e d . If the complete p r e - r i f t section and basement cannot be penetrated at this s i t e , then these objectives should be attacked at site 4a.

Ug 10"? - Ubrador Sea

Recommendations

ARP believes that Neogene and Paleogene paleoceanographic records should be aajor objectives at the leg 106 Baffin Bay and I^brador sea s i t e s . Furthermore, the Baffin Bay site i s s u f f i c i e n t l y unique that, i f conditions permit, time at th i s s i t e should be extended and d r i l l i n g should be continued as deep as possible even i f this reduces time available for the Labrador Sea si t e s . Conversely, i f weather precludes work i n Baffin Bay, then d r i l l i n g at Site LAS should be done to basement to ensure that Neogene and Paleogene objectives are attained.

Yucatan basin

The panel empdasize again that Yucatan d r i l l i n g must be a part of a suite of d r i l l i n g s i n the Caribbean basins. An up to date proposal must be prepared with the help of KUtgord.

Leg 107 - Tyrrhenian Sea :

KECCMMENDATION The ARP recommends unanimously the following order of p r i o r i t i e s for leg 107 in the T/rrheniah Sea:

Estimated D r i l l i n g Time Logging

S i t e 2 Site lb ( a l t . la) Site 3a ( a l t . 3a', then 4) Sit e 5b Site 7a

4.0 d 6.0 d

10.0 d 7.5 d 7.5 d

-O-1.5 d 1.5 d 1.5 d 1.5 d

35 6.0 d

Desicnated backups are s i t e s 5A. 6 and 8, in that order.

At both s i t e s 5b and 7a, ARP supports a s c i e n t i f i c r a t i o n a l e callir.;', fop penetration of both the o l d e s t observable sedimentary sequences and basement in order to estimate minimum oceanic (?) basement ages in both the Vavilov and Marsili basins.

At sites lb (la) and 3a (3a'/4), ARP recommends penetration to the base of the postulated s y n r i f t sequences discerned on both regional and s i t e - s p e c i f i c MCS profiles

Leg 108 - W Africa

RECOMMEKDATION

ARP has examined again the leg 108 proposed sites and their recently revised d r i l l i n g estimates. Estimated times seen unrealisticaly short, and a l l eleven, s i t e s may not be achieved. Better times are needed i n order to allow the s i t e s to be p r i o r i t i z e d i n an order which w i l l s a t i s f y as many s c i e n t i f i c objectives as possible. ARP recommends: 1. A l l sites be double-cored to maximize resolution and recovery, even i f

fewer sites can be occupied. 2. Logging not be done at any s i t e s . 3. Better estimates of d r i l l i n g times be provided by OOP 4. Sites be occupied i n order of p r i o r i t y , rather than in order of geographic

proximity, as much as feasible 5. Cochiefs should provide a p r i o r i t i z e d ranking of a l l eleven s i t e s to ARP

and SOHP.

Leg 110 - Barbados

J . Mutter - VSP on LAF 1 would be desirable. ARP agreed on t h i s suggestion

In conclusion the ARP position on leg 110 i s the following: ARP reaffirms i t s previous position that OOP proceed with Barbados leg 110. s i t e s LAF 1-6, regardless of the a v a i l a b i l i t y of advanced technology such as wireline packer or d r i l l - i n casing. ARP believes that the f i r s t p r i o r i t y objective i s to penetrate the decollement to oceanic crust, but the value of the leg as proposed does not hinge on t h i s target. ARP strongly advocates the s c i e n t i f i c objectives of s i t e s LAF 1-6 proposed by Mascle and Moore, also by Tectonics Panel and Caribbean Working Group, that embody a p a r t i a l transect across the Lesser A n t i l l e s forearc to investigate the changes in physical properties and deformation rates and mechanisms in the progressive growth of an accretionary prism. ARP recommends immediate review of a l l proposed s i t e s by Safety Panel and that HPF cores on Leg 110 be oriented.

Nevertheless ARP recommends that- i f bare mov n -^ndt. II oare rock drill.-i.ng doco not vvork Kane FZ

i s s t i l l a p r i o r i t y leg.

Sub antarctic d r i l l i n g

Reconunendation

The ARP, after reviewing the subantarctic d r i l l i n g plan submitted by SOHP to JOIDES, and while acknowledging i t s importance in providing potentially necessary "extra" time for Weddell Sea d r i l l i n g , recommends that this d r i l l i n g be considered within the broader perspective of South Atlantic d r i l l i n g targets. Unanimous.

Discussion on workshops

Within the next few years, ARP wiU promote workshops. The f i r s t one w i l l be devoted to the South Atlantic.

APPENDIX J

Southern Ocean Panel Meeting - Woods Hole, September 19-20, 1985

Major points i n minutes and updates;

1. Weddell Sea Leg: What i s the status of the support icebreaker?

2. Subantarctic Leg: S i t e surveys are to be conducted by J . LaBrecque between Ju l y to September, 86, almost c e r t a i n l y from the Polar Duke. W i l l obtain SCS, 3.5 kHz, piston cores, and magnetics and g r a v i t y data.

3. East Antarctic-Southern Kerguelen Leg;

a. Prydz Bay-East A n t a r c t i c Margin

F i r s t order problems of c l i m a t i c , sedlmentologlc and near-shore environmental hi s t o r y of East Antarctica e s p e c i a l l y i n Paleogene and Mesozoic. Nature of vegetation? Climatic conditions? Any i c e sheets? Major implications for global environmental i n t e r p r e t a t i o n s .

Shallow shelf sequences of dipping r e f l e c t o r s i s about 2,500 m t h i c k . Can be obtained by d r i l l i n g 3 to 4 sections with s t r a t i g r a p h i c overlap. Four sections of about 600 m penetration i s preferable.

Deep s i t e (3,000 m; o r i g i n a l l y K-4) i s problematic because of slumping. Also 900 m penetration i s needed. Australians have other p r o f i l e s that need examination. F i r s t order problem i s the age of the continental stripping r e s u l t i n g from i n i t i a t i o n of i c e sheets.

b. Southern Kerguelen

P r i o r i t i z a t i o n of s i t e s i s s t i l l preliminary because of planned s i t e surveys by French Investigators. K-11, K-5; K-12 and K-7. T h i s provides a minimum of depth coverage, together with s t r a t i g r a p h i c coverage, and basenent penetration.

4. Northern Kerguelen: Three primary s i t e s KH-1; KH-3A; KE-5A. Following d r i l l i n g plan suggested:

D r i l l KH-1 to 900 m i n t o top of r e f l e c t o r I I , then move to KH-3 and do exploratory d r i l l i n g to about 300-400 m to top of I I . Attempt re-entry, wash down and continue d r i l l i n g to basement; d r i l l KH-5. KH-4 renains as alternate basement s i t e . SOP l i k e s s i t e S8B and suggests keeping i t as an a l t e r n a t e s i t e . Considerable colleague pressure has developed to d r i l l t h i s s i t e .

sop's best estimate of d r i l l i n g plus logging times for d r i l l i n g KH-1; KH-3 and KH-5 are 57-68 days.

5. Because of the pressure of d r i l l i n g time required for accomplishing the numerous objectives of the East A n t a r c t i c margin and Rerguelen region coupled with long t r a n s i t times; SOP continues to strongly request crew change i n Kerguelen Island.

6. Workshop on the South P a c i f i c - A n t a r c t i c margin to be held In G a i n e s v i l l e , F l o r i d a on A p r i l 20-21, 1986. Cosponsored by SOP and CEPAC.

Summary of the Broken Ridge D r i l l i n g Program: The Response of the L i t h o s p h e r e to R i f t i n g Processes, and

A t e s t of Late Cretaceous Hotspot Models.

Broken Ridge, a r e l a t i v e l y shallow water p l a t f o r m i s o l a t e d from land areas i n the e a s t e r n Indian Ocean, was r i f t e d along i t s southern margin from the Kerguelen Plateau p r i o r to Middle Eocene time. By v i r t u e o f i t s d i s t i n c t i v e s e i s m i c s t r a t i g r a p h y ( F i g . 1), Broken Ridge i s an a t t r a c t i v e t a r g e t f o r OOP d r i l l i n g to determine whether r i f t f l a n k u p l i f t i s a p r e c u r s o r to act u a l r i f t i n g ( f i n i t e e x t e n s i o n ) , o r whether such u p l i f t i s a consequence o f the r i f t i n g p r o c ess. Furthermore, d r i l l i n g w i l l be able to determine whether Broken Ridge o r i g i n a l l y formed as the product o f Late Cretaceous hotspot volcanism. D r i l l i n g O b j e c t i v e s :

A t o t a l o f 4 primary s i t e s ( o r 7 s i t e s t o t a l i f contingency s i t e s are d r i l l e d ) are proposed on Broken Ridge ( F i g . 2) to address the f o l l o w i n g two o b j e c t i v e s : 1. A N-S t r a n s e c t o f holes a c r o s s the c r e s t o f Broken Ridge i n

The N-S t r a n s e c t o f 2 h o l e s ( o r 4 h o l e s i f the c o n t i n g e n c y s i t e s are d r i l l e d ) i s intended to c o n s t r a i n the u p l i f t / s u b s i d e n c e h i s t o r y o f Broken Ridge s i n c e the Late Cretaceous, and by p r o v i d i n g ages and paleodepths f o r the pre- and p o s t - r i f t sequences, the t i m i n g between u p l i f t and r i f t i n g at Broken Ridge w i l l be determined.

In an active r i f t i n g process, u p l i f t oreeedea actual r i f t i n g as heat i s introduced into the plate from below, presumably due to a convective thinning process.

P r i n c i p l e O b j e c t i v e s : . The program o f d r i l l i n g on the Nine t y e a s t Ridge i s based around

fo u r major themes, two o f which are o f broad general i n t e r e s t and two o f which are unique to the Indian Ocean.

The two problems o f g l o b a l i n t e r e s t are the major o b j e c t i v e s . They are: 1.

Summary of the I n t r a p l a t e Deformation, D i s t a l Bengal Fan D r i l l i n g Program

I n t r o d u c t i o n A unique example of i n t r a p l a t e deformation i s found i n the

Cen t r a l Indian Ocean b a s i n , south o f India ( F i g . 1 ) . Oceanic c r u s t and o v e r l y i n g sediments are deformed i n t o long-wavelength (-200 km) undulations and are d i s r u p t e d by c l o s e l y - s p a c e d (-5-10 km) f a u l t s showing a r e v e r s e sense o f motion ( F i g s . 2, 3 ) . G r a v i t y anomalies suggest t h a t the s u r f a c e o f oceanic Moho i s deformed i n t o u n d u l a t i o n s s i m i l a r to those observed i n the s u r f a c e o f the c r u s t . A l s o a s s o c i a t e d with the r e g i o n o f deformation d e f i n e d on the b a s i s o f s i n g l e - c h a n n e l s e i s m i c r e f l e c t i o n s p r o f i l e s are (a) i n t r a p l a t e earthquakes, whose f o c i l i e below the o c e a n i c c r u s t , and (b) abnormally high heat flow values d i s t r i b u t e d w i d e l y over the C e n t r a l Indian Ocean b a s i n . Many o f the measured s u r f a c e temperature-depth p r o f i l e s are n o n l i n e a r , c o n s i s t e n t with an upward flow o f water w i t h an average v e l o c i t y o f 7 x 10"^ m/s. Such f l u i d flow i s h i g h l y unusual i n view o f the t h i c k , uniform sediment cover o f Bengel Fan d e p o s i t s , and the age o f the u n d e r l y i n g c r u s t .

From the s t y l e o f the deformation and the f o c a l mechanisms determined f o r s e v e r a l i n t r a p l a t e events, we b e l i e v e t h a t the Indo-A u s t r a l i a n p l a t e i s deforming under l a t e r a l (-N-S) compression, which probably dates from Late Miocene time. However, the Late Miocene age i s p o o r l y c o n s t r a i n e d , stemming from a l i m i t e d number o f p i s t o n c ores from the deformation, and the age o f a prominent unconformity d r i l l e d at DSDP S i t e 218.

SUMMARY OF THE DRILLING PROGRAM FOR . , NEOGENE EVOLUTION OP THE INDIAN OCEAN MONSOON \ r. '-^ -

AND ITS RELATION TO MILANKOVITCH RADIATION CHANGES,jji^ . MOUNTAIN BUILDING, AND THE EVOLUTION OF MAN

The paleocllmatlc history of t r o p i c a l A f r i c a , the northern Indian Ocean, and southern Asia Is dominated by the evolution of the Indian Ocean monsoon. The monsoon c i r c u l a t i o n causes seasonal upwelllng along Arabia, transports t e r r e s t r i a l dust Into the Arabian Sea, and controls the p r e c i p i t a t i o n budget of t r o p i c a l A f r i c a and southern Asia. Long term variation of these c l i m a t i c and geologic processes r e l f e c t changes In the solar radiation budget of the Northern Hemisphere (I.e., Mllankovltch o r b i t a l cycles) and terrigenous boundary conditions such as the elevation of the Tibetan Plateau. Hence, the coastal uptrelllng, the productivity of the Arabian Sea, the eollan transport, the growth of the Indus Fan, the history of the oxygen minima zone, and the vegetation history of the surrounding continents are a l l affected by the in t e n s i t y of the Indian summer monsoon. This confluence of atmospheric, oceanic, and geologic processes gives r i s e to a number of important problems that can be uniquely addressed by d r i l l i n g In the northwestern Indian Ocean.

B r i e f l y , the major topics and objectives Include:

1. What Is the h i s t o r y of Neogene monsoonal upwelllng and how does I t vary In response to changing radiation budgets? The r o l e and evolution of the Indian monsoon as a major component of the global climate Is a major unanswered question In paleoceanography/paleodlmatology.

2. What Is the deposltlonal and dlagenetlc h i s t o r y of the highly organic r i c h sediments deposited i n the oxygen minima zone (OMZ) beneath the zone of proximal upwelllng? These sediments are expected to contain annual laminations (such as the gulf of C a l i f o r n i a ) which w i l l address questions of Interannual and decadal v a r i a b i l i t y and s t a b i l i t y of the OMZ.

3. How does the growth of the Indus Fan record the u p l i f t of the Tlbet-Hlmalayan complex, the deposltlonal h i s t o r y of the f l u v i a l Slwallks of Pakistan, and climate related changes In eustatlc sea level?

4. How Is the evolution of homlnid/homlnolds related to climate changes caused by the u p l i f t of mountains and changes In monsoonal pre c i p i t a t i o n ?

Proposed Sites

To address these problems, we propose an integrated transect of seven s i t e s i n the Western Arabian Sea and a d d i t i o n a l s i t e s ( 2 ) i n the Gulf of Aden and off East A f r i c a . B r i e f l y , these are:

1. Oman Margin s i t e s (NP 1, 2, 3) An HPC depth transect along the upper slope that crosses the oxygen minima

zone and w i t h i n the zone of proximal upwelllng. Sediments are organic r i c h and are expected to contain annual laminations. Due to high accumulation rates, penetration of 200M i s expected to obtain only Plio-Pleistocene age sediments. Proposal 31 of lOP. Survey to be completed 5/86.

-2-

2. Owen Ridge sites (NP 4, 3) Two HPC/XCB sites to obtain a Late Neogene high resolution history (around

10 MY) of upwelling and eolian deposition related to the Indian Ocean summer monsoon. Sites are located within the upwelling zone but above the effects of bottom processes on the margin and Indus fan. Proposal 30 of lOP. Survey to be completed 5/86. 3. Indus Fan sites (NP 6, 7)

Two HPC/XCB sites on the westernmost midfan to obtain a relatively continouus record of fine grained sediments that record the growth history of the fan. Sites to be located away from major channels on midfan to avoid sand lobes in the distal fan. Survey to be completed 5/86. Proposal reflects aspects of lOP proposals 14, 20, 33, 51, and 976. 4. Gulf of Aden (NP 8) and East Africa (NP-9)

One HPC/XCB at each site to recover the sequence of terrestrial components, such as pollen and volcanic ash, originating in East Africa within^ a well dated (bio-magneto stratigraphy) marine sediments. Comparison of the marine and continental paleodlmate data with the stratigraphy of hominld deposits is expected to give insights into the role of large scale climate changes in hominld and mammalian evolution. Proposal 68 of lOP.

Summary of the Red Sea D r i l l i n g Program

The Red Sea Working Group met at IFREMER, Brest, Ftance on September 23-25, 1985. A proposed d r i l l i n g program for one leg of work In the Red Sea (~ 60 days Including transit) was developed. This program Is based around four themes, two of which can be uniquely addressed In the Red Sea and are of general Interest in understanding the E^rth.

These two are:

1. Evolution of the Itthosphere through the transition from continental r i f t i n g to seafloor spreading as expressed by the nature of the igneous rocks produced at d i f f e r e n t stages i n t h i s process.

2. Hydrothermal a c t i v i t y and metallogenesis. The Sed Sea offers an opportunity to establish a "natural laboratory" in an active hydrothermal system, as well as to investigate f l u i d hot rock interactions and the hasement a l t e r a t i o n . >

TVro other themes are related to p r i o r i t i e s established by OPD panels. These are:

1. Miocene and, holocene paleoenvlronments and paleo-oceanography. The p a r t i c u l a r objective Is a study of Red Sea sapropels.

2. Mantle Section. The Red Sea presents an opportunity to obtain an unserpentlzed and undepleted mantle section.

A program was developed around those themes consisting of about 10 holes and about SO days of on-site d r i l l i n g . Roughly eight days of t r a n s i t are required f o r a D j i b o u t i - D j i b o u t i leg so that the program consists of a standard length (57-60 days) CD.P. leg.

The s i t e s which are proposed are as follows:

1. Transition from continental to oceanic d r i l l i n g . a) 17'-18*N - A x i a l trough (1, possibly 2 holes)

4-5 m.y. old sea f l o o r ( I s t hole) 2-3 m.y. old seafloor (2nd hole)

b) Nereus Deep - Northernmost seafloor spreading c e l l of propagating r i f t - This i s ah a c t i v e brine deep and thus the basalts are l i k e l y to be altered and more useful f o r hydrothermal and metallogenesis studies.

c) Bannock Deep - Southernmost of the small northern Red Sea deeps that have not reached the stage of seafloor spreading.

d) Shaban (Jean Charcot) Deep - The most northern of the small northern deeps a t which igneous rocks can be sure to be reached.

e) Mahablss Deep - seafloor spreading c e l l i n i t i a t e d under d i f f e r e n t circumstances then the southern deeps (nucleation point as opposed to propatlng r i f t t i p .

2 s i t e s : one on SW s i d e , one on NE side

2. Hydrothermal a c t i v i t y and metallogenesls. a) Nereus Deep - An active hydrothermal system In which a re-entry cone

w i l l be placed to establish a natural laboratory. Objective here Is not sediments, but rather to d r i l l 200m Into basement rock to study plumbing of a hydrothermal c e l l and rock f l u i d Interactions.

3. Pllocene-Holocene paleoenvlronment - faleooceanography. 7) Main trough 24*2I'N - high resolution biostratigraphy and sedlmen-

tology through the Holocene-Pliocene sedimentary sequence. b) Sudanese delta - second s i t e in shallower water to test o r i g i n of

Red Sea sapropels. 4. Mantle Section - Rresh, unserpentinized mantle periodotltes are exposed

on Zabargad Island and the submarine ridge extending away from the Island presents an opportunity to obtain a section of unserpentlzed, undeplated mantle.

F t i o r i t i e s The working group p r i o r i t i z e d Its s i t e s in terms of where they would >

carried out on a leg from Djibouti to Dj i b o u t i with higher p r i o r i t y s i t e s c the way north and lower on the way south. They are l i s t e d geographically In the order they would be done on such a program with estimated times and some d e t a i l s .

Prelixninaiy GEPMZ Ranking o£ Major P a c i f i c D r i l l i n g

26 SeptPiTiyr 1985

The following l i s t was conpiled of the major P a c i f i c problems relevant to the d r i l l i n g program. The l i s t i s a collection of themes rather than discrete d r i l l i n g legs. Site selection should provide some economy by locating holes for multiple objectives. Even so, i t i s clear that the number of important objectives far exceeds time presently allocated for d r i l l i n g i n the Central and Eastern Pacific.

The l i s t and rankings (low points equals high rank) are subject to revision as the themes become more defined. We have indicted the approximate time needed for each theme and the extent of surveying s t i l l required.

J2ilE_fifiala 1. Establish a state-of-the-art borehole measurements capability

within the Ocean Drilling Program.

2. Acquire a worldwide marine logging data base.

3. Expand the role of geophysics and borehole measurements in the Ocean Drilling Program by sponsoring sites and legs of interest to the borehole measurements community.

Tmn1»m»ntiktinn

To achieve the first goal, the Panel advocates a 3-pronged approach:

1. Contract with industry for the best available commercial logging

services. This has been achieved by LDGO through an extremely favourable

contract with Schlumberger under which Schlumberger maintains and operates

their most advanced field equipment from the D/V JOIDES Resolution while the

Project provides a teat platform for the company's experimental tools.

2. "Organized* equipment upgrades by LDGO. Many modifications or

pieces of equipment needed by the Program are too specialized for commercial

development or too complex and expensive for development by individual

investigators; these muat be developed directly or through subcontracts let by

LDGO. This effort baa been partially successful: the Panel's highest priority

tooKwirellas heave oompenaator) has been built and deployed but budget cuts

have prevented or seriously delayed the development and deployment of a l l

remaining toola on the Panel's high priority l l a t (wireline packer; digital

BHTV; multichannel sonio).

3. Equipment from individual inveatiaatora. To encourage both the

introduction of new equipaent and the widest participation in the Program, the

Panel has endorsed and, in many instances, solicited proposals from individual

investigators to develop and operate the following tools:

straddle Packer 3 Axis Magnetometer Magnetic Susceptibility HPC Water Saopler VSP Oblique Seismic Large Scale Resistivity Geotecbnical Wireline Re-entry

With the exception of the wireline re-entry and borebole geotecbnical

instrumentation proposals, a l l bave been funded. Proposals are currently being

sought for high temperature logging, geoteohnical tools and a borebole

graviaeter.

To achieve the second goal (a oompretaenaive marine logging data base),

the Panel adopted a "400 meter rule" stating that a l l holes over 400 m deep

sbould be logged. As an aid to the soientific party on each leg, the Panel has

instituted a review of the sites and objectives of each leg and designs a

downhole measurements program for each site which is tailored to meet the

objectives of the leg.

From its inception, the Panel has felt that, in addition to its role as

a service panel, i t has a responsibility to serve as a thematic panel for the

field of geophysics. To this end the panel sponsored and manned Leg 102, is

currently sponsoring the geophysical studies planned in Hole 395A on Leg 109,

has proposed a return to Hole 418A to deepen the hole into the dikes and

complete the borehole studies begun on Leg 102, and endorses the drilling and

logging efforts proposed at Site 504 and on the East Pacific Rise (Leg 111),

special Prolaeta

1. High TWPtratwr^ LwlrtIW« since many of the objectives of bare

rock/hydrothermal d r i l l i n g can only be met i f high temperature logging

equipment i s available, the Panel has set it s e l f the task of locating and

securing such equipment for ODP use. An extensive suite of gear is now

available for Leg 111 (Appendix 1).

2. Hydrogeolcgic Testing for Leg 110. Four sets of hydrogeologic

measurements (in addition to routine logging) are considered critical to the

success of the leg: pore pressure/in a l t u stress, water sampling, temperature

and borehole geotechnical. Current capabilities are as follows:

- Pore presaupe/in situ stress. Two packers (Lynes, TAM) will be available for pore pressure and stress measurements. Stress orientation can be measured with the BHTV.

- Water sampling. The TAM wireline packer will not be available (see above) but interstitial water can be obtained using the Barnes tool and satisfactory samples can be obtained from the aquifer ( i f it's overpressured) using the Barnes sampler and the PFS sampler.

- Temperature. Satisfactory measurements can be obtained using the HPC temperature probe, the Uyeda tool and Schlumberger logs.

- Geotechnical properties. No equipment i s available. A proposal by McClelland Englneera to upgrade existing equipment for deepwater use was rejected by the NSF.

Problea ATOM 1. Cuts to LDGO tool acquisition budget.

2. Long term measurements at high temperatures (electronics currently limited to about 225*'C).

3. Need for geotechnical/physical properties and geochemical working groups.

1985 ANNUAL REPORT OF SITE SURVEY PANEL J.W. PEIRCE, CHAIRMAN

DECEMBER, 1985

During 1985 the S i t e Survey Pannel (SSP) met i n June i n H a l i f a x and i n November i n Tokyo.

In o r d e r t o p r o v i d e a c o n s i s t e n t s e t of g u i d e l i n e s f o r the p l a n n i n g and assessment of s i t e s u r v e y s , the SSP f i n a l i z e d and r e f i n e d the S i t e Survey Data Standards m a t r i x (p.65 i n the s p e c i a l issue of JOIDES J o u r n a l ) . F u r t h e r a m p l i f i c a t i o n s to i t a r e b e i n g w r i t t e n , based on our e x p e r i e n c e from hands-on a s s e s s ment of s i t e s u r v e y s t h i s y e a r .

The s i t e s u r v e y d a t a f o r the C h i l e T r i p l e J u n c t i o n was f o r m a l l y reviewed i n A p r i l and found to be c l e a r l y i n a d e q u a t e . As no a d d i t i o n a l s i t e s u r v ey was p o s s i b l e , p l a n s f o r d r i l l i n g t h e r e have been dropped.

At the June meeting the SSP agreed t o t a k e on the r e s p o n s i b i l i t y o f f o r m a l l y a s s e s s i n g the s i t e s u r v e y d a t a s e t s f o r each d r i l l i n g package, b e g i n n i n g w i t h Leg 110. Because o f the e x t r a work l o a d o f t h i s r e s p o n s i b i l i t y , the SSP r e q u e s t e d a second member from the U.S. (Langseth and Duennebier have now r e p l a c e d O r c u t t ) and have asked the U.S. and Japan t o f i l l t h e i r v a cant a l t e r n a t e p o s i t i o n s .

To d a t e , p r e l i m i n a r y assessments have been done f o r the Peru T r e n c h , Weddell Sea and Nor t h K e r g u e l e n . S h o r t c o m i n g s have been i d e n t i f i e d , and the SSP and the Data Bank a re w o r k i n g w i t h the p a r t i e s i n v o l v e d t o get t h e s e gaps f i l l e d .

- 2 -

Advance input on s i t e survey plans has been given f o r the Sub-Antarctic, Southwest Indian Ridge, Neogene Package, and Makran areas. Detailed s i t e by s i t e assessment forms a r e compiled for mature d r i l l i n g proposals which have completed s i t e surveys with the data deposited in the Data Bank. A general summary i s available for the s i t e survey status in the Indian Ocean and a panel member has been assigned r e s p o n s i b i l i t y to. follow each major d r i l l i n g package. A similar summary i s in the i n i t i a l stages of preparation for the Western P a c i f i c .

The Data Bank budgeting s i t u a t i o n i s a matter o f great concern to the SSP. The cuts which were imposed in FY1986 were i l l o g i c a l i n concept and arbit r a r y in administration. The res u l t w i l l be that the Data Dank w i l l not be able to support the ODP community to the extent demanded, and most of the cuts w i l l be related to requests for d r i l l i n g proposals and for post-cruise science. F i r s t p r i o r i t y needs (SSP, PPSP and Science Operator) w i l l not be affected d i r e c t l y .

The SSP considers the maintenance of a well organized, centralized data base to be esse n t i a l to optimize the science of ODP. The ODP Data Bank must be funded adequately for SSP and PPSP to function properly. The SSP fee l s that PCOM has not supported the Data Dank as strongly as i t should have i n 1985. We trust that more support for the Data Bank w i l l be forthcoming from PCOM and the ODP community now that the JOI Review Committee has submitted i t s p o s i t i v e report.

APPENDIX P n

Report of the Information Handling Panel meeting, College Station, Texas, September 9-11, 1985

Summary

1. Publications policy. The IHP restated I t s firm committment to a strong ODP publication program, and concluded that the two-part program adopted l a s t year by PCOM s t i l l best meets the needs of the s c i e n t i f i c community. To deal with the current f i n a n c i a l s h o r t f a l l the Panel endorses the conclusions and recommendations of the PCOM Publications Review Subcommittee. Ve recommend that (I) post-cruise conferences proceed on schedule; (2) a l l necessary material for Part A volumes be ready at the post-cruise conferences; (3) as a temporary expedient basic, cheaply-printed I n i t i a l Core Descriptions be produced for the early legs; (4) as Part A volumes can be completed, they are shelved to await funding for publication; (S) Part B. manuscripts be scheduled as o r i g i n a l l y planned, and shelved when received to await funding for editing and printi n g . The Panel concluded that ODP must maintain r e s p o n s i b i l i t y for publication of "Part B" peer-reviewed s c i e n t i f i c reports i y some means, and our proposal for a Part B volume seems ultimately to serve best the s c i e n t i f i c community at a cost no higher than alternative proposals.

The IHP feels that the proposed "steady state" publications costs of $2.1 m i l l i o n are reasonable and In li n e with percentage publication costs of other large science programs. Ve recommend that publications be given a very high p r i o r i t y when and i f additional funding becomes a v a i l a b l e , to f a c i l i t a t e e a r l i e s t possible publication of Part A volumes. I f anticipated Improvement In funding does not occur, IHP asks to meet on an emergency basis to evaluate further options.

In our assessment, i f the results of the ODP are not published In an adequate and coherent form, the Project loses i t s only universally v i s i b l e product.

2. Logging data. IHP recomaenda that the routine wireline logging results be published, as edited and selected by the logging operator i n consultation with the science operator, i n Part A at the scale of the barr e l sheets. I f f i n a n c i a l or production constraints preclude t h i s , representative logs should be published and the presense of a l l logging data Indicated on the core descriptions. Hon-routine downhole measurements should appear as Individual s c i e n t i f i c experiments In Part B.

3. Other subjects. The following matters were also considered at the IHP meeting, and are covered i n the attached report.

(a) Logging data d i s t r i b u t i o n policy (b) Appointment of a l i a i s o n to IHP from the logging operator. (c) Sample curation po l i c y , e s p e c i a l l y regarding requests f o r

whole round core samples for destructive shipboard analysis. (d) Status of ODP data bases and data a q u l a i t i o n (e) Status of Nieropaleontology Reference Centers (f) Status of ODP computer services (g) Heed for representative sampling for consistent c o r r e l a t i o n

of various measurements, (h) Relation of ODP Data Bank at LDGO to other data banks and

services. (I) Request for a Japanese representative on IHP.

APPENDIX Q

ANNUAL KEPORT OF THE POLLOTION PREVENTION AND SAFETY PANEL

G. Claypool, Chairman, reported that during 1985 the PPSP met in New Orleans, La. in March and in Paris, France in October.

At the March meeting the Safety Panel discussed potential safety considerations for drilling in hydrothezmal areas and agreed that advice should be sought frcm experts (e.g. Los Alamos Laboratories) in the area of hot rock drilling. In addition, the panel examined proposed drilling sites for Legs 104 (Nooîan Sea), 105 (Baffin Bay) and Leg 106 (MABK).

Leg 104: PPSP reviewed 7 sites, approved 3 aa proposed and placed conditions on the remaining 4 sites. The panel also expxeased oonoem that previous drilling during D6DP (Site 341) demonstrated the presence of shallow biogenic gas and fluorescence suggestive of mlgrabed hydrocarbons. For that reason rotary drilling vas not approved in this area.

Leg 105: Having approved a l l Baffin Bay sites at the August 1984 meeting, the Safety Panel reviewed 8 prospective Labrador Sea sites. PPSP approved 4 as they were proposed, 3 with conditions and rejected 1.

Leg 106: PPSP approved both MABK-IA and MABK-IB as they were proposed.

At the Paris meeting, PPSP reviewed proposed drilling sites for Legs 107 (Tyrrhenian Sea), 108 (NW Africa), 109 (lARK II) and 110 (Barbados).

Leg 107: PPSP reviewed 16 possible sites, approved 9 as they were proposed, approved 4 with conditions and rejected 3.

Leg 108: PPSP reviewed 8 possible sites and approved a l l as they were proposed.

Leg 109: PPSP approved deepening of the Leg 106 WBK I site.

Leg 110: PPSP reviewed 7 proposed sites, approved 5 as they were proposed a i ^ approved 2 with conditions. The Safety Panel also advised that special aigineering methods may be required to d r i l l the high-pressure zone enommtered during D6DP Leg 78A drill i n g .

During 1985, the PPSP has also revised and rewritten the Safety Manu2d. this manuscript has been subodtted to the JOIDES Office for publication.

The f i r s t meeting had been q u i t e s u c c e s s f u l ! , and the members had had the o p p o r t u n i t y to d i s c u s s and give t h e i r b e s t advices about nine t e c h n i c a l items, the three more important being :

. hard rock spud-in

. h c r i r r o c k d r i l l i n g

. hard rock d r i l l i n g and r e c o v e r i n g .

A second meeting had been contemplated f o r the s p r i n g 1985, but Great B r i t a i n was then unable to commit as a f u l l member and consequently Dr F r a n c i s r e s i g n e d from h i s TEDCOM chairmanship. Some months e l a p s e d b e f o r e the French ODP r e p r e s e n t a t i v e body proposed my name as a candidate chairman f o r TEDCOM. I was nominated by the PLACOM i n June 1985.

P r i o r commitments and my p a r t i c i p a t i o n to the search and d i s c o v e r y of the T i t a n i c prevented me to work f o r TEDCOM before the month of September. From t h a t time u n t i l the end of November, I made c o n t a c t s with Dr Larson, TAMU e n g i n e e r i n g group people and a l l the TEDCOM members, w r i t i n g to them and c a l l i n g or v i s i t i n g them. Most of them answered e n t h u s i a s t i c a l l y , being very eager t o see t h i s committee brought to l i f e again and to p a r t i c i p a t e to i t s work.

Meanwhile, i n order t o get, as q u i c k l y as p o s s i b l e , answers to s p e c i f i c q u e s t i o n s , TAMU has taken the i n i t i a t i v e to o r g a n i z e and h o l d a t e c h n i c a l workshop. T h i s workshop took p l a c e e a r l y September i n C o l l e g e S t a t i o n (Texas) and was devoted to the examination o f the main t e c h n i c a l and e n g i n e e r i n g problems of the p r o j e c t , by an attendance of e n g i n e e r i n g and s c i e n t i s t s connected d i r e c t l y t o the p r o j e c t . The main o b j e c t i v e o f t h i s workshop was not to s o l v e the problems, but r a t h e r t o e s t a b l i s h p r i o r i t i e s between the problems t h a t have t o be s o l v e d by the manager of e n g i n e e r i n g and d r i l l i n g o p e r a t i o n s and h i s team.

Th i s workshop was a l s o an o p p o r t u n i t y f o r TAMU and Barry Harding to g i v e the a t t e n d i n g s c i e n t i s t an overview of the d i f f e r e n t equipments designed f o r and used by the p r o j e c t .

Attendees had to f i l l a form l i s t i n g more than 2 5 among them they ranked p r i o r i t y ONE :

. B i t development

. Heave compensator c o m p a t i b i l i t y f o r p i s t o n c o r i n g

. Hard rock spud system

. High temperature d r i l l i n g / c o r i n g adaptations

and s i x others were ranked medium p r i o r i t y . _*_

I I - TEDCOM GOALS

As I wrote i t to a l l the members l a s t October, I t h i n k s t r o n g l y t h a t TEDCOM must act l i k e a b r i d g e between the s c i e n c e p a r t y and the e n g i n e e r i n g p a r t y . For that purpose, TEDCOM members, a c t i n g with t h e i r knowledge and experience of the f i e l d , w i l l have three o b j e c t i v e s :

1. To ensure t h a t e n g i n e e r i n g and s c i e n c e are p r o p e r l y c o o r d i n a t e d , which means t h a t the e n g i n e e r i n g p r i o r i t i e s be coherent with the s c i e n c e p r i o r i t i e s but which means a l s o t h a t the s c i e n c e p r i o r i t i e s be compatible with the e n g i n e e r i n g and budget c a p a b i l i t i e s .

2. To be sure that the p r o j e c t make use of any r e l e v a n t experience-

3. To ensure t h a t the t e c h n o l o g i c a l aspects of the p r o j e c t are conducted i n the best way compatible with the a c t u a l budget and t h a t the R&D p r i o r i t i e s are sound.

ODP i s a l s o an i n t e r n a t i o n a l p r o j e c t i n which money, s c i e n c e and technology are to be shared. I t i s the reason why I want to g i v e TEDCOM a f o u r t h o b j e c t i v e :

4. To care t h a t f o r each l a r g e c o n t r a c t c o n c e r n i n g e i t h e r a purchase of equipment o r a development study, i n d u s t r i e s have been c o n s u l t e d on a world-wide b a s i s , and t h a t the best t e c hnology from the member c o u n t r i e s i s used everytime i t i s a v a i l a b l e .

TEDCOM must not be an a u d i t i n g body, a c t i n g d i s t r u s t f u l l y v i s - a - v i s TAMU engineering team. I f these four, o b j e c t i v e s , which I thin k each of you agrees with, are ODP o b j e c t i v e s , thus the r o l e of TEDCOM i s to help TAMU to f u l l f i l l them.

Br i n g i n g o u t s i d e views and h o p e f u l l y new id e a s , TEDCOM w i l l c o n t r i b u t e to a b e t t e r e f f i c i e n c y of the p r o j e c t .

I I I - TEDCOM PLANNING

I have proposed t h a t the next meeting w i l l take p l a c e i n M a r s e i l l e , February 17-20, us i n g the o p p o r t u n i t y of the p o r t c a l l of the J o i d e s RESOLUTION between l e g s 107 and 108. So the member c o u l d have a view of the s h i p , and have a b e t t e r comprehension of the problems.

I t w i l l be a l s o the o p p o r t u n i t y f o r the new chairman t o host the meeting i n h i s own co u n t r y .

The agenda of that meeting i n c l u d e s f i r s t an examination of the e n g i n e e r i n g accomplishments i n the past year of the budget problems, of the t e c h n i c a l problems. I t i n c l u d e s a l s o two mini seminars, one on hot rock d r i l l i n g , the oth e r on r i s e r d r i l l i n g . In our mind, t h i s mini-seminar on r i s e r d r i l l i n g w i l l be the f i r s t step towards a l a r g e r one which c o u l d be h e l d next f a l l .

TEDCOM meeting frequency i s not yet d e f i n i t e l y s e t . But we presume t h a t 8 months i n t e r v a l s would be re a s o n a b l e .

APPENDIX S DRAFT POOM i s asked to establish a Steering Ccramittee and tems of reference for COSOD-2.

1. POOM w i l l establish a aosOD-2 Steering Catmittee consisting of 12 members and a chairman including one representative from each of the non-US partner nations.

2. The Steering Carmittee i s mandated to:

a. plan and organize a OOSOD-2 meeting to be held no later than July 1987. Attendance at COSOD-2 i s open to the world s c i e n t i f i c oanmunity.

b. the prime objectives of COSOD-2, bearing i n mind the s c i a i t i f i c and technical progress of the Ooean D r i l l i n g Program, to date are to make reoommeidations for future s c i e n t i f i c and technologicl objectives for the ODP. As part of this charge, specied attention w i l l be given to the developnnent of associated s c i e n t i f i c programs within the d r i l l i n g program.

c. produce a rqport/ within 6 months of C0S(X)-2, for distribution to relevant funding agencies and to the s c i e n t i f i c ooramunity on a worldwide basis.

HIGHLIGHTS OF THE 20-24 JANUARY 1986 PLANNING COMMITTEE MEETING

The following are the highlights from the January 1986 meeting of the JOIDES Planning Committee.

NATIONAL SCIENCE FOUNDATION REPORT

G. Brass (NSF) reported that there i s no clear picture emerging that i n d i cates how the the Gramm-Rudnnan legislation w i l l a f f e c t the approximately $32 M budgeted for ODP operations during FY 86. NSF i s unable to make any long term forecasts for the $36 M proposed for the FY 87 budget as i t has not yet been sent to Congress for review.

Brass asked VCOfl members to develop liaisons with continental d r i l l i n g agencies both nationally (e.g. i n the US relevant groups are the Deep Observation and Sampling of the Earth's Continental Crust, Inc. (DOSBOC), the United States Continental Scienti f i c D r i l l i n g Program and the Salton Sea S c i e n t i f i c D r i l l i n g Project) and i n t e r n a t i o n a l l y i n order to encourage cooperation and the sharing of technologies between the various organizations.

REVIIW OF JOIDES SCIENTIFIC ADVISORY STRUCTURE

Discussion of the present structure indicated that frustration with the system has resulted i n the resignations of the LITHP chairman and the SOHP c h a i r man. The f r u s t r a t i o n was based on a general f e e l i n g among LITHP and SOHP chairmen that there i s ah apparent lack of coordination between the panels, there i s an unnecessary duplication of effort among the panels, there i s a f e e l ing that the advice of the thematic panels i s largely ignored i n favor of recommendations from the regional panels and that some d i s c i p l i n e s within the geologic ccranunity (especially geochemistry) are not represented i n the present structure and are being overlooked. L a s t l y , there was a general feeling of a majority of the chairmen that panel liaisons presently have too many meetings to attend and this system i s not an effective means of communicating information.

The consensus of PCOM was that i t was premature to change the panel structure at this time although i t was recognized that there have been d i f f i c u l t i e s , e s p e c i a l l y i n terms of communications, between thematic and regional panels. In view of this situation a better inter-panel liaison network i s required. One e f f e c t i v e means of achieving this w i l l be to establish a meeting of the panel chairmen, to be held during the suraner (in addition to the annual meeting with PCOM). A second means i s to have relevant panels hold overlapping meetings in order to resolve conflicts on p r i o r i t i e s . The development of d r i l l i n g plans should be based on an identification, by the thematic panels, of the global thematic objectives which may be best attained in any p a r t i c u l a r region. Regional panels should take these themes as the basis for regional d r i l l i n g plans and there should be a further evaluation by the thematic panels. At t h i s time the re s o l u t i o n o f any c o n f l i c t i n g advice from the regional and thematic panels should occur. The POCM w i l l then construct a d r i l l i n g plan based on th i s flow of advice. PCOM further agreed that although the Program i s placed within a 10 yr. framework, i t should be emphasized that the boundary conditions are f l e x i b l e . I t was the general consensus that while thematic panels w i l l continue to receive

; 1

proposals, regional panels w i l l concentrate on detailed proposal review in the development of the regional plans.

PCOM agreed that COSOD-2 may provide an opportunity for a review and possible re-alignment of the panel structure. Meanwhile, PCOM w i l l consider ways to best include the views of the geochanical ccramunity into the planning process.

SHORT-TERM PLANNING

Leg 108 (NW Africa)

No problems are euiticipated for Leg 108 other thein those caused by clearance d i f f i c u l t i e s . The addition of a heat flew program has been <3iscussed and okayed with TAMU and the co-chiefs and w i l l be implemented by the physical properties specialist on RESOLUTION. In addition, engineering tests on the rainicore system and the sidewall logging sub w i l l be conducted.

Leg 109 (MARK-2)

It was consensus of the Downhole Measurements Panel and the Lithosphere Panel that the tole established on Leg 106 be deepened with seme logging conducted at the s i t e (Site 648 B) and that a f u l l s u i t e of logging be conducted at DSDP Hole 395A.

Leg 110 (Barbados)

TAMU indicates that there are no problems and that progress continues on d r i l l - i n casing development.

Leg 111

Recognizing the importance of sampling the deep oceanic crust in order to expand our present knowledge of the lithosphere, the PCOM recommended that Leg 111 be primarily devoted to the deepening and logging of Hole 504B.

In addition, the PCOM recommended that a maximum of 5 days be added to -ne program for d r i l l i n g double APC and XOB sites in the v i c i n i t y of Hole 504B with one s i t e to be a represeintative geochanical and paleontological s i t e . A f u l l logging program w i l l be undertaken with the i n c l u s i o n of a V e r t i c a l Seismic P r o f i l i n g (VSP) e3?)eriment. The PCOM also indicated that any decision to replace d r i l l i n g at Hole 504B by a third leg devoted to S i t e 648B w i l l be dependent on good results and substantial d r i l l i n g progress on Leg 109.

MEDIUM RANGE PLANNING (INDIAN OCEAN 1987/88)

Taking i n t o account the inposs i b i l i t y of obtaining s i t e surveys for the Mas-carene Basin/Fossil Ridges program, PCOM revised the program for Indian Ocean d r i l l i n g which i s given i n Table 1.

In considering the a v a i l a b i l i t y o f s i t e surveys for the Indian Ocean program, the POOM reccramended that the Mascarene B a s i n / F o s s i l Ridges program be eliminated from planning due to the in p o s s i b i l i t y of obtaining the needed si t e surveys. The POCM also noted that the acceptance of the Southwest Indian Ridge

(SWIR) and the 90<âst Ridge programs into the schedule may be prejudiced i f si t e surveys are not conducted in thpse areas and that Red Sea d r i l l i n g may be i n doubt due to p o l i t i c a l problems (clearance d i f f i c u l t y and security). Should these legs be eliminated from the program, POCM identified an additional Neogene Package leg, the Makran and a Scmali Basin deep stratigraphic test hole as potent i a l backups and these proposals w i l l be the subject of further evaluation.

LONG-TERM PLANNING (PACIFIC OCEAN 1989- )

Overall Time i n the Pacific Ocean

The PCOM recanmended that WPAC, CEPAC, SOP and the thematic panels develop a sc i e n t i f i c program for the Pacific Ocean under the i n i t i a l time constraint of a t o t a l of three years f o r t h i s entire region. It was indicated that the time i n the area w i l l be partitioned approximately equally between the western P a c i f i c (the general area mandated to WPAC) and the remainder of the Pa c i f i c (including the Bering Sea and far Southern Pa c i f i c ) . However, the POCM indicated that '^'"is time constraint and i t s division i s tentative and subject to revision i n co. d-eration of subsequent s c i e n t i f i c arguements frem the panels.

PANEL MEMBERSHIP

Panel Rotations

I t was the consensus of PCOM that the panels should propose a ro t a t i o n scheme for membership (noting that non-US members are npt required to adhere to the rotation) and should suggest possible replacements and additions to ensure as complete a disciplinary cover as possible. POOM w i l l decide on rotations and new membership at i t s May meeting following the above input from the panels.

Panel Chairmen's Meeting

PCOM agreed to appoint D. Rea (CEPAC) as chairman of t h i s group. It s agreed that the meeting would be held at OSU p r i o r to the next PCOM meeti..j. Subjects suggested for the agenda were: global review of thematic objectives of ODP; panel-panel and panel-PCOM ooramunications and improvements to working methods; r e s o l u t i o n of Indian Ocean plannir^ conflicts; identification of major objectives of Pacific Ooean d r i l l i n g and the inclusion of geochemical, s i t e survey and downhole measurements input into planning.

ANY OTHER BUSINESS

Rotation of the JOIDES Office

PCOM was informed that the JOIDES Office w i l l rotate to Oregon State Univers i t y as of 31 September 1986 and that OSU w i l l be succeeded, i n 1988, by the Hawaii Inst, of Geophysics. With t h i s r o t a t i o n , D. Caldwell w i l l succeed J . Knauss as the EXOOM chairman and N. P i s i a s w i l l succeed R. Larson as the PCOM Chairman.

COSOD-2

In responding to a mandate by the E5ffX)M, given at i t s Jan. 1986 meeting, the PCOti prepared a draft Terms of Reference for a COSOD-2 meeting. Offers to host the meeting were made by T. Francis, H. Beiersdorf and J-P. Cadet. The location w i l l be finalized at the May POM meeting. The steering committee w i l l consist of 12 members with one member from each of the non-US menibers plus a chairman. Selection of the Steering Committee and i t s Chairman w i l l be made i n May. The meeting w i l l be funded by co-mingled funds with t r a v e l to be a national responsibility.

JOIDES EXECUTIVE COMMITTEE

COSOD-II ARRANGEMENTS

1. Following the previous EXCOM meeting instruction, the Planning Committee has established a mandate for COSOD-II and i s seeking nominations from a l l PCOM members and USSAC for a Steering Ccnmittee (see attached note). At i t s May meeting, the PCOM w i l l select the Steering Ccmmittee and i t s Chairman.

2. O f f e r s to host COSOD-II have been received from the Federal Republic of Germany (to be held at Geological I n s t i t u t e of the University of K i e l ) , from the U.K. (to be held at St. John's College, Cambridge University), w h i l s t France has proposed that COSOD-II should be held under European "auspices," possibly at Strasbourg. A formal o f f e r to o r g a n i s e COSOD-II has been r e c e i v e d from the European S c i e n c e Foundation (the f u l l organisation including France, the Federal Republic of Germany, and the U.K. - not to be confused with the ESF Consortium for ODP).

3. A meeting of the national PCOM representatives w i l l be held i n mid-April and a "consolidated" view as to the venue and convening o r g a n i s a t i o n f o r COSOD-II w i l l be made to the E x e c u t i v e Ccmmittee.

4. The E x e c u t i v e Committee i s asked to decide on the venue for COSOD-II.

COSOD-2

PCOM was asked by EXCOM at their 7-8 January 1986 meeting to establish a steering committee and terms of r e f e r e n c e f o r COSOD-2. The following terms of reference were agreed by the PCOM at their 20-24 January 1986 meeting.

Terms of Reference

1. The prime objective of COSCO-2 i s to make recotmendations for future s c i e n t i f i c and technological objectives for the Ocean Dr i l l i n g Program, bearing in mind the s c i e n t i f i c and technical progress of the ODP to date. As part of this charge, special attention w i l l be given to the development of associated s c i e n t i f i c programs within the ODP.

2. PCOM w i l l establish a CbSOD-2 Steering Committee consisting of 12 members and a chairman including one representative from each of the non-U.S. partner nations.

3. The Steering Committee is mandated to:

JOIDES EXECUTIVE CC»1MITTEE

PARTICIPATION BY THIRD WORID SCIENTIgTS

1. During the year since the previous ODP Council meeting, when the proposal to seek ways and means to involve geoscientists from the T h i r d World i n ODP was endorsed, the JOIDES O f f i c e has been pursuing contacts with a variety of i n t e r n a t i o n a l organisations. The results of these actions are summarised below:

2. World Bank - Contact was made with relevant Bank o f f i c i a l s and information sent to than, but i t was made clear by these o f f i c i a l s that the chance of World Bank support i s ranote.

3. U.N. Development Program/Committee for Coordination of J o i n t Prospecting for Mineral Resources (OCOP) - The EXCOM Chairman has written to the chairmen of CCOP/AS (East Asia) and CCOP/SOPAC (South P a c i f i c ) t o seek t h e i r c o o p e r a t i o n i n terms o f communicating with the geoscience coranunities in these areas and to seek funding support for such s c i e n t i s t s . A d d i t i o n a l l y , i n d i v i d u a l members of JOIDES and interested Australian scientists are known to have raised ODP at CCOP meetings and the JOIDES Off i c e , has sent information packs to a l l the identified contact points. So far, this effort has not e l i c i t e d a response.

4. ICSU/Scientif i c Ccanmittee on Oceanic Research - Communication has been established with the SCOR Executive Canmittee. I t i s hoped that the issue of cooperation with ODP and the involvement of Third World s c i e n t i s t s w i l l be on the agenda of the next SCOR General Meeting to be held in November 1986 i n Hdaart, Australia.

5. I n t e r n a t i o n a l Union of Geological Sciences (lUGS) - Both the present president (Dr. W. Hutchison, Canada) and the past p r e s i d e n t ( P r o f . E. Seibold, DFG/FRG and ESF President) are members of the lUGS Executive Committee so that ODP should be well represented at this level i n lUGS. In addition, the Chairman (Dr. K. HsU) and Secretary (Dr. J . Thiede) of the lUGS Ccnmission on Marine Geology have been deeply involved i n ODP. A l l the above are on both the JOIDES and TAMU mailing l i s t s so as to keep abreast of ODP developments. Recently, the editor of Episodes/ the lUGS quarterly, has i n v i t e d the JOIDES O f f i c e to submit a feature a r t i c l e on ODP which, i t i s hoped, w i l l be published i n June. lUGS and i t s organisations provide an important channel of communication to the non-ODP s c i e n t i f i c community.

6. UNESCO/IOC - Correspondence has been exchanged between the EXCOtA Chairman and the Secretary of IOC (Dr. M. Ruivo) . IOC has responded p o s i t i v e l y to say that i t s Guiding Group of Experts for the OSNLR (Ocean Science in relation to Non-Living Resources) has s t r o n g l y encouraged p a r t i c i p a t i o n i n ODP by s c i e n t i s t s from developing c o u n t r i e s . Information c o n c e r n i n g ODP and the forthcoming Indian Ocean d r i l l i n g plans have been sent to Dr. H.N.

Siddiquie (Member of the Guiding Group of Experts and Director, Indian National Institute of Oceanography) who has been asked to pass information to relevant s c i e n t i f i c contacts i n the Indian Ocean region.

Dr. Ruivo has a l s o o f f e r e d to study, case by case, and according to funds available, the possiblity of funding t r a v e l for p a r t i c i p a t i n g s c i e n t i s t s and has also offered to assist i n acting as an information conduit for ODP.

7. Association of Geoiscientists for International Development (AGIO) T h i s o r g a n i s a t i o n has been approached f o r a s s i s t a n c e i n disseminating information about ODP to i t s members, but, to date, no response has been received.

8. Miscellaneous - A l l opportunities are being taken to disseminate information about ODP to i n d i v i d u a l s c i e n t i s t s i n Third World nations, to encourage t h e i r p a r t i c i p a t i o n , and to ask for their assistance i n terms of p r o v i d i n g governmental c o n t a c t s f o r furthering ship's clearance requests and i n helping with s i t e surveys. In particular, proposals for d r i l l i n g have been received from PRC, South Korea, and the P h i l i p p i n e s . In the f i r s t two cases, the proposals have been acccn^nied by offers of assistance in s i t e surveys.

A p p r o a c h e s have a l s o been made t o JOIDES t o make presentations on ODP as a t o t a l program and on P a c i f i c Ocean p l a n n i n g i n p a r t i c u l a r t o the Fourth Conference of the Circum-Pacific Council for Energy and Mineral Resources to be held i n S i n g a p o r e i n August 1986. I t i s hoped t h a t the PCOM Chairman-designate and the chairmen of the JOIDES Western P a c i f i c and Central & Eastern P a c i f i c Panels w i l l be able to attend this meeting. This should provide a useful forum for dissemination of ODP information to the general Pacific s c i e n t i f i c community.

9. The Executive Committee i s asked to note the above actions and progress and to advise as to any other contacts which should be approached.

TO: EXCOM Members

I r e c e n t l y r e c e i v e d a l e t t e r from one of you which in c l u d e d the f o l l o w i n g paragraph.

" I t may be worth p o i n t i n g out t h a t a few of us c h a t t i n g a f t e r the l a s t EXCOM meeting f e l t t h a t we would have l i k e d b r i e f w r i t t e n r e p o r t s from PCOM, L-DGO, TAMU, JOI, and perhaps NSF, but th a t i s l e s s c r i t i c a l I suspect. C e r t a i n l y I have found myself i n w r i t i n g up my notes o c c a s i o n a l l y u n c e r t a i n , and w r i t t e n r e p o r t s would be h e l p f u l . I think t h a t the ' d i r e c t o r s ' of a 36 m i l l i o n d o l l a r program deserve and need w r i t t e n r e p o r t s from those r e s p o n s i b l e f o r implementing the program and spending the money."

JOIDES EXECUTIVE C0M4ITTEE

FUTURE MEETING ARRANGEa ENTS

1. The next meeting of the JOIDES Executive Ccanmittee has been arranged for:

15-16 October 1986 at the Pacific Geoscience Centre, Sidney, Bri t i s h Columbia

2. I t has been the practise for EXCm meetings to follow VCCM meetings by approximately 4 to 6 weeks, although this has not been the case recently. There are c e r t a i n firm ccmnitments for meetings (EXCCM meeting with the ODP Council i n the Washington area i n Spring and the January annual meeting of PCOM with i t s Panel Chairmen). It has been the tradition for both the EXOOM and PCOM summer meetings to rotate amongst the non-U.S. partner nations. It has also been the tradition for both conmittees to meet at the JOIDES O f f i c e host i n s t i t u t i o n f a i r l y e a r l y within the normal two-year r o t a t i o n period.

3. Bearing the above constraints i n mind and noting that the summer EXCOM meetings have rotated as follows:

1983 Swindon, England (host- U.K.) 1984 Strasbourg, France (host- France & ESF) 1985 Bonn, Germany (host- FRG) 1986 Sidney, B r i t i s h Columbia (host-Canada)

i t i s suggested that EXCOM should adopt a 1987 schedule which i s given below:

January 1987 PCOM Annual Meeting early Spring EXOOM with ODP Council (Washington, DC area)

early Summer POCM (Japan) late Sumnner EXOOM (Japan)

approx. Sept. POOM late October EXCOM (Oregon State University)

JOIDES Office 3/86

JOIDES EXEICUTIVE COMMITTEE

JOIDES OFFICE ARCHIVES

1. At the end of the period of the Miami JOIDES Office, which coincided with the substantive change from DSDP to ODP, many JOIDES records were transferred to DSDP to form part of the DSDP archive.

2. With the impending transfer of the JOIDES Office frem URI to OSU, i t is appropriate to consider, in principle, the need, i f any, to create an ODP archive and its possible location.

3. It i s estimated that a maximum of approximately two f i l e cabinet drawers of material will accumulate as archival material during any two-year JOIDES Office period. Rather than build up an archival c o l l e c t i o n which i s constantly transferred from institution to institution with the JOIDES Office, i t i s proposed that an archive should be established either at JOI, or by analogy with DSDP, with the Science Operator at TftMU.

4. The Executive Conmittee is asked to consider this issue and advise accordingly.

DOSECC UPDATE - 2 MARCH 1986

DOSECC (Deep Observation and Sampling of the Earth's Continental Crust, Inc.) i s a private, non-profit corporation formed in 1984 bv a consortium of universities to design and manage a national continental s c i e n t i f i c d r i l l i n g program. DOSECC UPDATE is a source of communications for those interested in the d r i l l i n g program. Items in the newsletter include information about DOSECC a c t i v i t i e s and plans, uocoming s c i e n t i f i c d r i l l i n g - r e l a t e d meetings, details of U.S. research d r i l l i n g projects, descriptions of holes being d r i l l e d by industry, government, and academe that may provide opportunities for add-on s c i e n t i f i c investigations, and information on continental s c i e n t i f i c d r i l l i n g programs in other countries. If you wish to change your address or add other recipients to the mailing l i s t , complete the enclosed response form.

DOSECC SCIENTIFIC INVES.TI5ATI0NS PROPOSAL SUBMISSION PROCEDURES Proposals requesting support from DOSECC should address s c i e n t i f i c experiments that can best be conducted with the use of the d r i l l to provide samples or access for downhole measurements. Requests for support of workshops to define experiments and to assemble potential p r i n c i p a l investigators in multifaceted projects are also encouraged. Acceptance of a proposal i s preceded by review by DOSECCs Science Advisory Committee (SAC) of the s c i e n t i f i c merit and cost effectiveness of the proposed experiment, assessment of the d r i l l i n g cost and f e a s i b i l i t y , and appraisal of proposed downhole measurements and sample studies.

The following general guidelines w i l l be used to prepare proposals for o r i g i n a l s c i e n t i f i c projects and for experiments to be added on to projects, but w i l l not be used for the awarding of contracts such as d r i l l i n g , logging, and technology, which are based upon specifications and work statements. Announcements inviting s c i e n t i f i c proposals to specific projects w i l l be made as opportunities arise. However, proposals appropriate for DOSECC support may be submitted at any time. S c i e n t i f i c investigation proposals submitted to DOSECC w i l l involve at least two steps; pre-proposals and f i n a l proposals. A pre-proposal submitted to SAC should outline b r i e f l y the s c i e n t i f i c experiments involved and indicate their significance in terms of expected gain in new knowledge. Pre-proposals must specify the reasons that d r i l l i n g i s required. The pre-proposal i s then distributed by SAC to reviewers for evaluation of s c i e n t i f i c


merit. Followinq return of the reviews, SAC w i l l consider the proposal at i t s next meeting and then inform the author of i t s decision. If the recommendation i s favorable, a meeting w i l l be arranged between the principal investigator (PI), the DOSECC D r i l l i n g and Engineering staff, and the Downhole Measurements Advisory Panel to evaluate the f e a s i b i l i t y of the proposal, estimate costs, and consider downhole measurements. If SAC recommends not to support the pre-proposal, review comments w i l l be provided to the PI, who may then consider submission of a revised proposal or request funding for a workshop to refine or modify the or i g i n a l proposal.

Following provisional acceptance of the pre-proposal and consultation with the DOSECC technical support groups, the PI w i l l prepare a f i n a l proposal containing a detailed science plan, a d r i l l i n g , logging, and sampling plan, and a budget. The f i n a l proposal i s reviewed by SAC and, i f found acceptable, receives a p r i o r i t y for inclusion in DOSECCs overall program. DOSECC management acts on SAC recommendations by placing the project in the d r i l l i n g schedule. Once a s c i e n t i f i c d r i l l i n g project i s approved and a p r i o r i t y i s set, SAC appoints a Science Experiments Panel (SEP) to work with the PI to refine the project and insure broad awareness in the s c i e n t i f i c community of research opportunities. Public announcements w i l l s o l i c i t secondary proposals made possible by the proposed hole. Secondary proposals w i l l be reviewed by SEP and assigned a p r i o r i t y , depending on compatability and relationship with the primary-project—for-which the hole is-being-rhrilled,- their — s c i e n t i f i c merit, and the estimated cost, SEP submits recommendations regarding secondary experiments to SAC for f i n a l review and approval. This entire procedure may take as long as two (2) years.

Funding for workshops may be requested to modify proposals that have been rejected or to develop new experiments and projects. Negotiations for support of workshops are i n i t i a t e d by a l e t t e r proposal of not more than two or three pages to SAC, which w i l l either approve the workshop, request more d e t a i l , or reject the request. SAC w i l l assist in workshop arrangements. Lead time should be at least six (6) months.

DOSECC anticipates ephemeral opportunities to arise p e r i o d i c a l l y in the form of add-on experiments to d r i l l i n g a c t i v i t i e s of industry or government. These may involve deepening a hole or additional experiments or sampling in a hole already planned or being d r i l l e d . In such cases, a special proposal may be presented to SAC requesting rapid s c i e n t i f i c consideration and response.

For d e t a i l s on proposal formats check the appropriate box on the enclosed response form.

ILLINOIS SaPEROEEP DRILL ROLE WORKSHOP A s c i e n t i f i c workshop w i l l be held in Champaign, IL, 1-4 A p r i l 1986, to refine proposals for d r i l l i n g a superdeep s c i e n t i f i c research d r i l l hole in southern I l l i n o i s . The p r i n c i p a l purpose of the workshop i s to prepare a detailed report on the s c i e n t i f i c objectives of the project, including downhole instrumentation.

CONTINENTAL SCIENTIFIC DRILLING GENERAL WORKSHOP On 12-14 June 1986, DOSECC w i l l sponsor a general workshop at the South Dakota School of Mines and Technology to offer s c i e n t i s t s the opportunity to present proposals for continental s c i e n t i f i c d r i l l i n g projects. The workshop is open to individuals and groups pursuing research that requires d r i l l i n g samples and/or downhole measurements to answer basic questions concerning the structure, properties, and dynamics of the continental crust. The agenda w i l l include discussion of DOSECC*s program; related Department of Energy and U.S. Geological Survey projects; DOSECC 1986 projects; new proposals for d r i l l i n g and related experiments; and current d r i l l i n g , coring, and logging c a p a b i l i t i e s , constraints, and costs.

Abstracts should be submitted to SAC by 15 A p r i l 1986 to be considered for the workshop program. Interested parties should contact DOSECC by checking the appropriate box on the enclosed response form.

DOSECC DRILLING PROJECTS SCHEDULE Science Experiments Panels ( S E P ) have met on the Cajon Pass (CA) and Creede (CO) research d r i l l i n g projects. Deepening of the Cajon Pass hole from 1.3 km to 5 km is expected to begin in late 1986. DOSECC plans to issue a Request for Bids for a d r i l l i n g contractor in March. A f i n a l proposal from the project p r i n c i p a l investigators w i l l be completed in May, followed~by an infogmotion session at the American Geophysical Union Annual Spring Meeting in Baltimore, MD, on 22 May, to s o l i c i t proposals for additional science experiment proposals. D r i l l i n g for the Creede project should begin in 1987 with shallow (1 km) holes in the caldera moat sediments.

DOSECC WORKSHOP ON CRATONIC PROCESSES

A DOSECC-sponsored workshop was held at St. Louis, MO, 23-26 February 1986, to bring together expertise in geology of the continental i n t e r i o r . Logging, downhole measurements, and regional geophysics were discussed for the purpose of planning a comprehensive program of s c i e n t i f i c d r i l l i n g i n the continental interior aimed at understanding the processes important in the origin and evolution of the stable craton. The workshop organizer, W. R. Van Schmus, Department of Geology, University of Kansas, Lawrence, KS 66045-2124 [telephone: (913) 864-4974], can provide further information.

SALTON SEA SCIENTIFIC DRILLING PROJECT

In mid- February 1986, the Salton Sea S c i e n t i f i c D r i l l i n g Project in Niland, CA, reached a depth of 9450 f t in a diabase intrusion, with an equilibrium temperature of about 350OC. Thirty-three 30 spot cores have been collected, and a flow test was conducted at about 6200 f t . Lost c i r c u l a t i o n has caused problems in d r i l l i n g and coring. The target depth of 10,000 f t should be reached in the near future. For further information contact Prof. Wilfred A. Elders, Institute of Geophysics and Planetary Physics, University of Ca l i f o r n i a , Riverside, CA 92521.
