This work (Bulletin No. 55) is one of a series of papers intended to

illustrate the collections belonging to or placed under the charge of

the Smithsonian Institution and deposited in the United States National

Museum.The publications of the National Museum consist of two series—the

Bulletin and the Proceedings.

The Bulletin., publication of which was commenced in 1875, is a

series of elaborate papers issued separately and based for the most

part upon collections in the National Museum. The^^ are monographic

in scope and are devoted principally to the discussion of large zoolog-

ical groups, bibliographies of eminent naturalists, reports of expedi-

tions, etc. The bulletins, issued only as volumes with one exception,

are of octavo size, although a quarto form, known as the Special

Bulletin, has been adopted in a few instances in which a larger page

was deemed indispensable.

The Proceedings (octavo), the first volume of which was issued in

1878, are intended primarily as a medium of publication for newly

acquired facts in biology, anthropology, and geology, descriptions of

new forms of animals and plants, discussions of nomenclature, etc.,

A volume of about 1,000 pages is issued annually for distribution to

libraries, while a limited edition of each paper in the volume is printed

and distributed in pamphlet form in advance.

In addition, there are printed each year in the second volume of the

Smithsonian Report (known as the Report of the U. S. National

Museum), papers, chiefly of an ethnological character, describing col-

lections in the National Museum.Papers intended for publication by the National Museum are usuallj^^

referred to an advisory committee, composed as follows: Frederick

W. True (chairman), George P. Merrill, Otis T. Mason, James E.

Benedict, Walter Hough, T. W. Stanton, Leonhard Stejneger, and

Marcus Benjamin (editor).

A CONTRIBUTION TO THE OCEANOGRAPHY OF THE PACIFIC

By James M. Flint,

Medical Director, U. S. Navy; Curator, Division of Medicine.

INTRODUCTION.

In the early part of the year 1899 the U. S. S. JVero, a steam collier

of 4,925 tons displacement, which had been purchased for use during

the Spanish-American war, was fitted out by the Navy Department,

equipped with the necessary apparatus, and dispatched from San

Francisco under the command of Commander Charles Belknap, U. S.

Navy, with instructions to survey a route for a telegraph cable between

the United States, the Philippine Islands, and Japan.

On account of the illness of Commander Belknap, he was relieved

from command on the arrival of the ship at Manila by Lieut. Com-mander H. M. Hodges, U. S. Nav}^, who remained in charge of the

survey until its completion.

Several previous surveys having established a satisfactory route

between the coast of California and the Sandwich Islands, the actual

work of the JVero began at Honolulu, from which port the ship sailed

on the 6th day of May, 1899.

The following table of dates, distances, and number of soundings

furnishes an abstract of the cruise:

OCEANOGRAPHY OF THE PACIFIC. 6

TRACK. '

It would be unnecessai'}^ for the purpose of this study to attempt to

present in detail the exact courses followed by the vessel, which were

at times quite erratic, in the effort to find the most feasible location

for the cable. It is to be understood, therefore, that the accompany-

ing track charts do not represent the exact courses of the ship nor the

line determined upon for the cable or followed in the laying of it.

The stations charted, however, are supposed to be accurately located.

Before preparing the charts certain stations on the outward vojâge

were selected for careful examination of bottom material. The con-

siderations governing the selection were chiefly the depth, the macro-

scopic appearances of the bottom specimens, and the distances. These

stations were afterwards plotted and connected by a continuous line.

In a few instances outlying stations of especial interest have been

indicated on the charts, and a serial number and depth given for each.

On the first or diagrammatic chart the station numbers included

within each five degrees of longitude or latitude are given for both the

outward and homeward voyages. By means of this index it is easy to

locate approximately any station mentioned in the record.

DEPTHS.

The graphic representation of the contour of the ocean bed along

the course of this survey is less simple and satisfactory than usual,

because of the breadth of track explored and the large number of

soundings recorded. It should be noted, in examining the contour

charts appended, that-the lines are drawn from the localities indicated

on the track charts as stations selected for special examination of

bottom material, and one of the principal determining factors in the

selection was that of depth. Therefore, the contour charts may be

said to represent the extremes of elevation and depression along the

main line of the outward voyage only, without taking into account

intermediate or outlying irregularities of surface. The omitted sta-

tions can be easily supplied from the record if greater detail is desired.

Leaving the island of Oahu of the Hawaiian group, the depth

increases quite rapidly until it reaches about 2,500 fathoms. This

depth is reached less than 30 miles due north of the island. ' Fromthis point nearly to Midway Island there is a comparatively level

plain, broken only by two or three outlying peaks from the moun-

tain range whose highest summits show themselves as small islands or

reefs a little to the westward of the line of survey. One of these

peaks appears at station 93, where there is a sharp rise to 1,463

fathoms, which, however, as rapidly falls away to the normal level a

few miles to the northward. A smaller projecting spur is indicated at

station 106, 2,002 fathoms. Another sudden rise to 1,726 fathoms

4 BULLETIN 55, UNITED STATES NATIONAL MUSEUM.

appears at station 124, followed by depressions to more than 2,600

fathoms a few miles away, both to the westward and northward.

With these exceptions the range of variation is practically between

2,500 and 3,000 fathoms for the whole distance until the immediate

vicinity of the Midway Islands is reached.

About 30 miles to the southward and westward of Midwa}- Island a

very bold peak was discovered rising- abruptly from the ocean floor,

2,000 fathoms below the sea level, to a height only 82 fathoms below

the surface.

Passing from the vicinity of Midway Islands a nearh^ level plain is

found, extending about 1,000 miles to the westward, upon which the

extremes of depth of water are 2,926 and 3,382 fathoms. About mid-

distance between Guam and Midway Islands what is apparentlj^ a

mountain range is encountered, extending over 3^ of longitude, with

varying depths from 3,000 to 720 fathoms. On the westward side of

this mountain range another plain below the 3,000-fathom line extends

a distance of about 300 miles. From the western limit of this plain

until Guam is reached the contour is quite irregular. Extensive detours

both north and south of the direct course developed a mountainous

region, with peaks rising to 689 fathoms below the sea level, and val-

leys descending to a depth of more than 5,000 fathoms. Four sound-

ings below the 5,000-fathom line were made, with the record of 5,070,

5,101, 5,160, and 5,269 fathoms. These were in the ab3^ss now knowmas the "Nero Deep."" The last-named sounding was numbered 1488,

in latitude 12^^ 43' 15" north, longitude 145"^ 49' east, about 75 miles

east-southeast from the island of Guam, and is the deepest sounding

ever recorded, being onlj^ 66 feet less than 6 statute miles.

From Guam to Luzon the ocean bed is for the most part gently

undulating, at depths varying from 2,500 to 3,000 fathoms. About120 miles west of Gaum (station 688) there appears a sharp elevation to

1,346 fathoms, which however soon subsides to the normal depth of

about 2,700 fathoms. Again, about 600 miles from Guam (station

760) a rise to 1,560 fathoms is encountered. From the data at hand

this latter would seem to be a peak rather than a mountain range,

since soundings east, west, and south show speedy subsidence to nearly

normal depths. At station 784 the depth reaches 3,547 fathoms, with

several soundings in that vicinity below 3,000. Approaching Dingala

Bay on the east coast of Luzon and about 120 miles distant (station

864) another peak appears with summit only 821 fathoms below sea

level. In this instance also, soundings north, east, and west soon

develop normal depths.

From Guam to Yokohama the route lies to the westward of the

Ladrone Islands and to the eastward of the Bonin group. For a dis-

tance of 500 miles or more from Guam the soundings show a gently

undulating plain at an average depth of about 2,100 fathoms. Between

OCEANOGHAPHY OF THE PACIFIC. 5

latitude 21° 45' and 22" 8' north and longitude 143° 45' and 143° 20'

east three sharp peaks arise along- a line about 35 miles in length

and northwesterl}^ in direction. On the first, or most southerl}^, the

sounding record is 483 fathoms; on the second, about 18 miles awaj,

the record is 838 fathoms; and on the third, 20 miles farther to the

northwest, 802 fathoms. There are vallej^s 1,000 fathoms deep

between these peaks. The indications point to a continuous range of

mountains connecting the Ladrone Islands with the Bonin group.

After dropping downi the eastern slope of the above-mentioned peaks,

the depth increases by an easy gradient to 3,595 fathoms at station

1095, rising and falling gently until at station 1126 a sounding of 9Y2

fathoms locates an outljdng spur from the Bonin range. Still farther

to the northward and westward, at station 1135, the bottom drops

to 3,421 fathoms, followed by gentle slopes up to 1,500 and down to

2,900 fathoms, until the Gulf of Tokyo is reached.

GRADIENTS.

In computing the gradients from station to station serially on the

outward voyage onl}^ involving 1,100 soundings, sixty-nine localities

only are found where the gradient exceeds 10 per cent. These higher

grades are for short distances only, averaging less than 5 miles, and

confined to a few regions, especially to the vicinity of Midway Islands,

Guam, and the mountain range halfway between the above-mentioned

islands. Of the sixty-nine localities showing a grade above 10 per

cent, fifty have an incline between 10 and 20 per cent, eleven between

20 and 30 per cent, and six between 30 and 40 per cent. At the

entrance to Port Tarafofo, on the east coast of Guam, two soundings

one-fourth of a mile apart show a difference of depth of 123 fathoms,

equivalent to a gradient of about 51 per cent. Also on the declivity of

the peak southwest of Midway Islands, which rises to 82 fathoms

beneath the surface of the water, there is a change of depth of 1,269

fathoms (T,614 feet) in a horizontal distance of 1.8 sea miles, a gradient

of 70 per cent. With these few and localized exceptions the bed of the

Pacific Ocean, as developed b}^ this surve}^, though rising here and

there near to the sea level, and again descending to depths of 5 or 6

statute miles, follows easy gradients. On the great plain to the west-

ward of the Midway Islands, 1,000 miles in breadth, the average

gradient is less than 1 per cent—in one instance only rising to 4.5 per

cent, for a distance of 2 miles.

TEMPERATURES.

AIR AND SURFACE WATER.

The temperature of the air on board the ship, and of the water near

the surface, was taken at nearlj^ all the sounding stations. These sta-

tions numbered, on the average, about ten each day on the outward


voyage, and eight on the return voyage, distributed at nearly equal

intervals over the twenty-four hours.

The following table presents the results of certain computations

from the official records. (All temperatures are given in degrees

Fahrenheit.)

The high temperature average,between 800 and 900 fathoms, is due to

the exceptional record of 41°.! at station 1225, in immediate proximity

to the volcanic island of Oshima or Vries Island, at the entrance

to the Gulf of Tokyo; also two records of 39° at stations 1569 and

1570, on the summit of a high peak or ridge about 450 miles to the

eastward of the island of Guam. The average of the other four

records is 36^.97.

In the series of observations at depths between 1,000 and 1,500

fathoms there is record of 38° at station 1678, and 37°. 3 at the adjoin-

ing station 1677. These two stations are on one of the peaks of the

mountain range in midocean between Midway and Guam. There are

no other records of temperature above 37° at these depths.

Only two stations between the 1,500 and 2,000 fathom line record

temperature above 37°, namely: Stations 1000, 39°. 3 and 1009, 37°. 3,

about 60 and 120 miles, respectively, to the northward of Guam. There

is probability of error in one or both of these observations.

In making up the average of temperatures between 2,000 and 3,000

fathoms, 16 of the 266 observations have been omitted from the

calculations. In some of these cases "incorrect" is noted on the

original record; in others, the probability of instrumental or clerical

error is so much greater than the probability of existence of local

conditions capable of producing such deviations from the normal

range of temperature as to justify their exclusion. The omissions are

stations 131 (44°), 138 (51°.7), 140 (44°.8), 232 (39°.4), 243 (38°.2),

477 (38°.8), 479 (44°.5), 719 (67°.6), 722 (67°), 723 (67°), 962 (37°),

1508 (33°), 1511 (33°), 1512 (34°), 1513 (34°), 1514 (34°). The last five

of these rejected observations were taken b}^ a thermometer concern-

ing which it is noted: " Correction not known." This thermometer

OCEAlSrOGEAPHY OF THE PACIFIC. 9

being replaced b}^ another, the temperatures are again recorded at the

normal of 35° and above.

Of the 188 temperatures taken at depths from 3,000 to 4,000 fathoms,

10 have been excluded from the computation of averages, for the

reasons given above. They are the following: Stations 239 (52°), 244

(38°), 251 (38°.9), 257 (60°), 312 (38°.4), 422 (37°. 8), 489 (40°.2), 501

(37°.4), 790 (32°), 809 (22°. 9).

Three temperature observations were made between 4,000 and 5,000

fathoms, and two at depths of 5,070 and 5,101 fathoms respectively,

all in the abyss southward and eastward of Guam.The obvious inference from the above computation is that the tem-

perature of that part of the Pacific Ocean covered by this survey falls

rather rapidly from the surface to about 600 fathoms, then very slowly

to about 2,500 fathoms, where the normal temperature varies but

slightly from 35° F. Below 2,500 fathoms there appears to be a

slight rise of a fraction of a degree. But it is open to question if

this apparent rise may not be due to the effect of the enormous pres-

sure of three to five tons to the square inch, at these great depths,

upon the instruments.

CHARACTER OF BOTTOM.

The character of the bottom indicated on the record by abbrevia-

tions, refers onl}^ to the gross appearances of the material recovered

in the sounding cup, when fresh from the water. Translated into the

terms of the usual scientific classification, the brown mud ('"''br, m.")

of the record is generally the red clay of the oceanographer, or rarel}^

volcanic mud from deep water. With few exceptions what is desig-

nated coral sand ("co. s.") is globigerina ooze. The rock (R. or r.)

has, in every case examined, proved to be fragments of pumice or

manganeseiron concretions; the black specks also are almost always

particles of manganese iron. Except in the immediate vicinity of a

shore, gravel (G. or gvl.) is, in this part of the ocean at least,

coarse volcanic debris which has been distributed by wind or wave all

over the sea, and has finally found its way to the bottom. The sand

(S. or s.) so often noted consists of finer mineral particles from the

same source as above-mentioned, except near the shores of islands.

Other abbreviations than those just given, used in the columns for

character of bottom, refer to color, size, etc.^—bk= black; br= brown;

dk — dark; gy= gray; It— light; rd=red; wh= white; y. oryl=yellow;

lied clay.—Of the above-mentioned classes of deposits by far the

most extensive is red cla3^ This, as it appears in the specimens

received, is a smooth, sticky mud, varying in color from light yellowish-

brown (fawn color) to dark chocolate, these colors being somewhat

modified in individual instances by exposure to light, and especiall}^

b}^ drying. In composition it consists of (1) extremely fine, amorphous

particles of cla3êy matter, mosth^ hydrated aluminum silicate and the

debris of other minerals; (2) the remains of calcareous organisms

(foraminifera, coccospheres, and rhabdospheres), this constituent, how-

ever, rapidly disappearing at depths of about 2, 500 fathoms; (3) siliceous

organic remains (sponge spicules, radiolarian skeletons, and the frus-

tulesof diatoms; (4) mineral fragments, mostly of volcanic origin, at

least in this part of the ocean; and (5) certain products of local chem-

ical reactions, especially nodules, coatings, and grains of manganese

peroxide, crystals of phillipsite, and particles of palagonite. The pro-

portions of these constituents vary greath" along the line and even

from station to station. As has been stated, foraminifera disappear,

for the most part, at depths below 2,500 fathoms; radiolaria are likely

to be more numerous in the deeper waters; diatoms are nearl}^ ever}^-

where, but only occasionally in great numbers. Mineral fragments

may be so minute in some specimens that they pass over almost

entirel}^ in the fine washings, while in others they may be compara-

tively coarse. Volcanic glass is sometimes present in notable quantity.

Manganese-iron nodules, and concretions upon other minerals, are

almost universally present. They are the black specks ("bk. sp.") so

frequently recorded on the official records, the larger ones being gener-

ally referred to as rock C"' R.'') Phillipsite is a freqent constituent.

It is found as quite perfect crystals, single, twinned, or multiple, or

more frequently as spherules made up of crystals arranged radially. Thesimpler forms are found in great numbers at station 331 (2,997 fathoms),

and the spherules at station 495 (3,204 fathoms). Vertebrate remains,

teeth of sharks and other fishes, and otoliths, have not been observed

in this or other deposits, though carefull}- looked for.

This red clay deposit is indicated in 75 per cent of the soundings

from which specimens were received (1,043 out of 1,394), between the

Hawaiian Islands and the Philippines. It is conspicuously absent

except at three stations along the line from Guam to Yokohama, being

replaced at corresponding depths b}^ volcanic mud. It is probal)le

that this belt of volcanic mud does not extend far from the range of

volcanic islands along which the cable route passes.

The least depth at which a distinctly red cla}^ deposit has been noted

is at station 680—2,010 fathoms. It is always found in abysmal depths.

Ordinarily, as the contour line rises above the 2,500-fathommark foram-

inifera rapidly increase in numbers and perfection of form, and soon

justify the classification of the deposit under the head of globigerina ooze.

Glohigerina ooze.—Globigerina ooze is defined as a deposit containing

over 30 per cent of calcium carbonate, principally in the form of

minute shells of foraminifera. Other organic remains commonlyfound in this deposit are sponge spicules, radiolaria, diatoms, and the

ver}^ minute coccoliths and rhabdoliths. As a rule, in this part of the

Pacific Ocean globigerina ooze will be found wherever the depth is

less than 2,200 fathoms. The exceptions are found in the region of

volcanic islands or submarine volcanic peaks where the foraminifera

seem to be overwhelmed by volcanic sand, and in the vicinity of island

shores where coral sand or blue or green mud may predominate. Theglobigerina ooze, wherever found on the line of this survey, is composed

principally of the few species (about 20) of foraminifera known to be

pelagic. Bottom living species are rare and individuallj'^ few in num-ber. The proportion of mineral matter, other than calcium carbonate,

in this deposit is relatively small. Manganese concretions are gener-

ally present and sometimes quite numerous, and fragments of pumice

are common. Crystals and spherules of phillipsite a,re often noted.

The finer mineral fragments are quite lost in the mass of foraminifera,

but appear when the latter are dissolved out with acid. At one sta-

tion—643, 1,757 fathoms—the cavities of very many of the shells were

found to be filled with a siliceous deposit forming complete casts of the


interior of the shells, even to the minute foramina. These casts are

also noted twice in volcanic mud (stations 991 and 1065). Doubtless

examples of these casts might be found in many other samples of

globigerina ooze.

Diatom ooze.—Diatom ooze is the name given to a deep-sea deposit

of which the principal constituent is the siliceous frustules of diatoms.

Previous to this survey such a deposit had not been found in any

tropical waters, and was supposed to be " confined to the Southern or

Antarctic oceans, or to the northern parts of the North Pacific."

Unexpectedly, therefore, many distinct patches of characteristic diatom

ooze were found on the line, especially between Guam and Luzon,

latitude 11° 28' to 11° 50' north, and longitude 136° to 130° 30' east.

Along this tract, about 300 miles in length, diatom ooze was recovered

at stations, as follows:

Diatom ooze.

Station.

OCEANOGKAPHY OF THE PACIFIC. 13

In some instances complete frustules are found, but usually the valves

are separated and often much broken. A peculiar feature of this

deposit is the strict limitation of the patches. Nearl}^ pure diatom

ooze may be recovered from one station, and at the next, five miles

away, not a diatom appear in the desposit.

Radiolarian ooze.—No well-marked example of radiolarian ooze has

been found in the specimens examined. Though radiolaria are noted

in most of the samples, nowhere do thej^ appear as a dominating con-

stituent of the deposit. They are most numerous in the diatom oozes,

where they are generally conspicuous bj" the number of individuals,

but the number of species represented is not great.

Volcanic mud.—This is a deposit found in the neighborhood of

volcanic islands or submarine volcanic peaks. Its characteristic con-

stituents are pumice, glass, ashes, and the debris of volcanic rocks.

It is often mixed with a considerable proportion of foraminifera whentaken from depths less than 2,000 fathoms. Most often it is dark gray

in color, and is readily disintegrated by shaking with water, being

devoid of the sticky quality of red clay. This deposit is noted about

the islands-of Oahu and Guam, and nearly the whole distance fromGuam to Yokohama, where the route passes along nearly parallel to

the Ladrone and Bonin groups of volcanic islands, and at no great dis-

tance therefrom. The most conspicuous mineral constituent of this

deposit is volcanic glass. It appeals in various forms, the most fre-

quent being the fibrous or filamentous variety. This has the appear-

ance of having been drawn out when in a plastic state, sometimes into

long, extremel}^ fine threads, more commonly into larger threads or

ribands, furrowed longitudinall}^, broken into short pieces, and alwa}-

s

colorless and transparent as the finest artificial product. Anotherform is more massive, ragged in outline, dark brown, translucent,

with numerous large, rounded cavities, and not so conspicuously sug-

gestive of having been drawn out while cooling. A third variety

consists of very fine, angular, perfectly transparent ;md colorless

fragments, which often make up the bulk of the washed sediment.

Red palagonite, coating fragments of other minerals is more fre-

quently present in this deposit than in an}^ other.

Blue mud.—Blue mud is the deposit generally found in inclosed or

partially inclosed seas, and in the waters bordering continental land. It

is composed for the most part of the debris carried out from the land

by rivers or other currents. The few specimens collected by the JSfero

are blue-black in color, on the sides of the vial exposed to the light of

a dark steel-blue with metallic luster, and iridescent. The color is

said to be due to the presence of organic matter and iron sulphide.

The odor of hydrogen sulphide is evident in all the well-corked vials

of this mud. Except in deep waters foraminifera are more or -less

numerous. Radiolaria and diatoms are generally present, sometimes

(r/'t()i hunl.—Green mud is found under the same eonditions as blue

mud. It is said to oAve its color o'cnerally to the presence of the oli\e-

oreen mineral glaucouite. but sometimes to the presence of oro-anic

matter and its reducing- action upon iron peroxide. In some instances

the o-reeu color of the specimens has turned a bluish-black since

recovery, and from ])reseut appearances would be called blue mud.

In all the specimen-; of green mud the tinge of o-reen is faint, and the

greenish grains of sand comprise but a small part of the sediment.

A large part of the coloration must be due to extremely minute amor-

phous mineral matter, since the supernatant Avater in the settling-glass

remains cloudy and tinged with green after standing for an hour, and

is not cleared or decolorized by uitro-hydrochloric acid. ]So g-lauco-

iiitic casts of foramiuifera have been noted in these specimens. Green

mini is recorded at several stations in Oingala Bay. coast of Luzon,

and at till stations but one from ]So. li!17 to the anchorage near

Yokohama, a distance of about 70 miles.
