1. Background

The Beaufort Regional Environmental Assessment (BREA) is an initiative to address oil and gas related issues in Beaufort Sea from a regional approach. The proposal was initiated and supported by stakeholders from the Inuvialuit Settlement Region, territorial and federal governments, and industry. It is a response to recommendations from the Beaufort Sea Strategic Regional Plan of Action (BSStRPA, 2008).

As environmental studies and planning for offshore exploration and production evolve, BREA will complement the existing work being conducted by the private sector in a regional perspective. It will assist in preparing all parties, including the federal government, to respond to new investments in oil and gas in previously unexplored areas of Beaufort Sea. The scientific information generated through BREA will allow more appropriate environmental assessments and regulatory processes for industry and regulators.

A necessary step to determine research priorities for future work to be undertaken through BREA is to review data collected during previous research programs and to identify environmental data gaps. In 2008, the Environmental Studies Research Fund (ESRF) conducted a data mining project with the objective to report data gaps relevant to the regulatory review, assessment and management of effects associated with offshore oil and gas exploration and development in the Canadian Beaufort Sea1. However, the scope of this study was mainly on technical reports and environmental assessments from industry and governmental agencies and did not cover academic-led science programs.

2. Objectives

Over the past decade, significant investments have been made through academic-led programs to research the Beaufort Sea environment. The objective of this report is to review and document the data collected in Beaufort Sea through these academic-led initiatives, mainly in the south Canadian Beaufort Sea-Mackenzie Shelf-Amundsen Gulf region, through the following research programs:

1. ArcticNet 2010 expedition including sampling conducted in and around EL446 and EL449 in collaboration with BP.

2. ArcticNet 2009 expedition including sampling conducted in and around EL446 and EL449 in collaboration with IORVL.

3. GEOTRACES and MALINA 2009 expeditions conducted in collaboration with ArcticNet as a contribution to the International Polar Year (IPY).

4. The Circumpolar Flaw Lead (CFL) System Study overwintering megaprogram conducted during the International Polar Year (IPY) in 2007-2008.

5. ArcticNet expeditions in 2005 and 2006.

ArcticNet - BREA data mining project 18

6. The Canadian Arctic Shelf Exchange Study (CASES) sampling program expedition conducted from 2002-2004 and including an overwintering expedition in 2003-2004.

A secondary objective of the report is to update the data collection efforts of other non-academic-led oceanographic programs in Beaufort Sea area over the last few years. In this report, the following program is documented:

7. The Beaufort Gyre Exploration Project (BGEP), based on the Joint Ocean Ice Study (JOIS, 2005-2010) and the Joint Western Arctic Climate Study (JWACS, 2003-2004).

This review provides BREA stakeholders with information as to what has been collected where (metadata), as well as indication of the environmental data gaps (topical and geographical) for Beaufort Sea.

3. Data sources

The following sources were scrutinized to record all relevant metadata:

1. The Polar Data Catalogue (307 metadata sets from the Beaufort Sea area and ~700 Radarsat images).2

2. All ArcticNet's annual reports, mission plans and cruise reports (which include reports of MALINA and GEOTRACES missions).3, 4

3. CFL's cruise reports.5-12 4. CASES' cruise reports.13-21 5. Some ArcticNet affiliated scientists in charge of studies related to valued ecosystem

components in Beaufort Sea were contacted to ensure that all past and recent studies are included.

6. BGEP's cruise reports.22-29

4.1. Data mining summary and topical data gaps

Based on the tables in annex (section 7), this section summarises all data collected throughout the science programs detailed in the objectives (section 2). In this report, research topics (hereafter referred to as “indicatorsˮ) were identified as data gaps if, during these science programs, 1) they were not or rarely studied compared to other indicators, and/or 2) sampling was limited to specific locations rather than covering a large area, and/or 3) sampling was restricted to a short period of time compared to sampling for other indicators. As physical, biological and geochemical processes constantly vary and as few are fully understood, all components and indicators would benefit from additional sampling effort. However, sampling related to topics identified as data gaps was scarce compared to other indicators.

4.1.1 Atmosphere Summary. Air quality and meteorological data were continuously recorded throughout CASES, CFL and ArcticNet missions. Sensors located on top of the CCGS Amundsen bridge recorded atmospheric CO2 and H2O concentrations while others located on a tower at the ship’s bow monitored winds, precipitations, temperature and irradiance. Meteorological data were collected by the team of Tim N. Papakyriakou (University of Manitoba). Cloud cover concentration and ceiling were also recorded by an all-sky camera and a ceilometer. Radiometer-equipped weather balloons were regularly launched and transmitted wind, temperature and humidity profiles. Metocean buoys were also deployed at the ocean-atmosphere or ice-atmosphere interface to record meteorological data near the surface. During CFL, the OASIS project focussed on atmospheric turbulences. Gary Stern's team (DFO Winnipeg) regularly collected air samples to measure ozone and contaminant concentrations (e.g. mercury, pesticides, organic contaminants), and ice-atmosphere buoys were deployed at different locations to monitor CO2 and ozone concentrations as part of JWACS and JOIS expeditions. During CFL, the SOLAS project focussed on the atmospheric concentration of DMS and other aerosols. Throughout all expeditions, meteorological data were continuously recorded by an Automatic Voluntary Observing Ship (AVOS) system installed on all Canadian Coast Guard icebreakers. Two satellites, ENVISAT and MODIS, also recorded irradiance, aerosol concentrations and cloud imagery since 2002. Data gaps. Several atmospheric variables were collected during all oceanographic expeditions documented in this report. However, atmospheric contaminant concentrations were not measured during JWACS and JOIS expeditions in the Deep Canada Basin. The

ArcticNet - BREA data mining project 20

studies documented in this report were mostly field-based and no data resulting from modeling of the atmospheric conditions were reported. 4.1.2 Ice and physical oceanography Summary. Ice and physical oceanography were priorities of CFL, CASES, ArcticNet, JWACS and JOIS missions. Several instruments were moored since 2002, mainly to record bottom ice depth and roughness, currents and water masses characteristics (e.g. salinity and temperature). Yves Gratton's team (INRS) deployed a CTD-rosette equipped with probes and sensors (oxygen, pH, fluorescence, nitrates and irradiance) at most station sampled along the cruise track of the CCGS Amundsen and a Moving Vessel Profiler (MVP) regularly measured on-track temperature and salinity profiles. The ship-mounted ADCP and thermosalinograph continuously measured currents and surface layer properties during all expeditions mentioned above. Turbulence in the water column was measured during CFL and JOIS 2009 expeditions. Snow and ice samples were collected on a regular basis by David G. Barber's team (University of Manitoba). Ice thickness and roughness, wave characteristics, surface temperature and ice/ocean surface microwave emissions were also monitored. Ice buoys and GPS beacons were regularly deployed to track ice motion during several months. Aerial ice surveys were occasionally conducted, and satellites (RADARSAT, MOBIS, ENVISAT) continuously monitored the ice and snow cover during the past decade. Data gaps. Knowledge on extreme and Potentially Unmanageable Ice Features (PUIFs) composed of old multiyear ice was identified as high priority for the construction of off-shore oil platforms. However, such features were not studied throughout the science programs detailed in section 2. Moreover, academic-led programs focussing on snow and ice characteristics were mostly conducted in southeastern Beaufort Sea and characteristics in the Deep Canada Basin are not as documented, especially during winter. Finally, ice and physical oceanography studies documented in the annex (section 7) were mostly field-based or remote sensing observational studies and no data from modeling studies were reported. 4.1.3 Chemical oceanography Summary. The concentration of contaminants (e.g. mercury, pesticides, organic contaminants) in sediments, water, air and living organisms (mainly zooplankton and fish larvae) was measured during ArcticNet, CFL and CASES expeditions (Gary Stern's team). Contaminant concentrations in snow and sea ice were also measured during CASES and CFL programs. Water samples were collected during GEOTRACES 2009 for estimating concentrations of trace-metals and of isotopes of various elements (e.g. Ra, Th, Pa, I, Si, Cr).

ArcticNet - BREA data mining project 21

Large-scale efforts have also been conducted to quantify water and atmospheric CO2 and CO concentrations and to describe the carbon cycle. Since 2002, an extensive program using long-term moored sediment traps was developed by Louis Fortier's team (Université Laval) to measure vertical particle fluxes. Sinking export of organic material was also measured from free-drifting sediment traps by Christine Michel's team (DFO Winnipeg). Oxygen, DMS and DMSP concentrations in the atmosphere and water were regularly measured throughout all missions documented in this report, with greater sampling efforts during the Arctic SOLAS program in 2009. Nutrient concentration profiles were determined on selected transects during CASES, CFL and ArcticNet surveys by Jean-Éric Tremblay's team (Université Laval). Finally, total gas concentration in ice was measured throughout the CFL expedition. Data gaps. Even if contaminant concentrations in sediments, water and atmosphere were regularly measured, little information is available from JWACS and JOIS expeditions in the Deep Canada Basin. Moreover, throughout the science programs detailed in section 2, studies on contaminant concentrations in fish were limited to larval and juvenile stages, and concentrations in marine mammals were only resolved for ringed seals and belugas near specific Inuit communities (mainly Ulukhaktok and Tuktoyaktuk). 4.1.4 Primary production and microbiology Summary. Understanding the dynamics of phytoplankton was highly prioritized throughout CASES, CFL, ArcticNet, JWACS and JOIS expeditions, particularly near marginal ice zones. Chlorophyll a and phaeopigment concentration profiles, along with turbidity data, were regularly measured from rosette sampling and from CTD sensors. Michel Gosselin's team (UQAR) determined the evolution of phytoplankton biomass and diversity on several transects in southeastern Beaufort Sea. In the same area, Christine Michel's team used free-drifting sediments traps to study primary production, Connie Lovejoy's team (Université Laval) studied microbial diversity and Jody Deming's team (University of Washington) documented viral abundance and diversity. Finally, PAR intensity was measured during all programs mentioned above using a probe on the CTD-rosette. Sea ice algae diversity and abundance, as well as chlorophyll a concentration in sea ice, were also measured, mainly during CASES, CFL, JWACS and JOIS expeditions. Sediment samples were regularly collected and analyzed for diatom markers, which are used as indicators of past primary production. During the MALINA expedition in 2009, several primary production indicators were measured and compared with remotely-sensed data (e.g. data from the SeaWIFS satellite). Data gaps. Primary production studies mostly focussed on phytoplankton biomass and diversity. Sampling of ice algae and water during the spring phytoplankton bloom, a crucial

ArcticNet - BREA data mining project 22

period for primary production in Beaufort Sea, was limited to specific locations in Amundsen Gulf and Franklin Bay during CASES and CFL programs. Lab-based incubation studies were scarce during the science programs documented in this report and no data from primary production modeling studies were reported. 4.1.5 Zooplankton Summary. Diversity, abundance, as well as vertical and horizontal distribution of zooplankton, were studied throughout ArcticNet, CASES and CFL programs (Louis Fortier's team). Since 2007, experiments and incubations were conducted to evaluate copepods egg production and respiration rates from samples collected in Amundsen Gulf. A Video Plankton Recorder (VPR) camera was used throughout CASES and MALINA programs to estimate diversity and abundance of zooplankton. Contaminant concentrations and stable isotope ratios in the zooplankton assemblage of southeastern Beaufort Sea were regularly measured (Gary Stern's team). Zooplankton samples were also collected during JWACS and JOIS missions for taxonomy, DNA analysis and biomass measurements. Data gaps. Knowledge about zooplankton contaminant concentrations and trophic interactions (based on stable isotope ratios) is limited in the Deep Canada Basin. Throughout the science programs documented in this report, respiration rates studies based on incubation experiments were restricted to samples collected in Amundsen Gulf. No modeling study related to zooplankton, or to the Beaufort Sea marine ecosystem in general, was reported. 4.1.6 Marine fish Summary. Existing data on marine fish mainly concern the larval and juvenile stages of the Arctic cod (Boreogadus saida) from southeastern Beaufort Sea. Sampling of the adult stage of Arctic cod was limited to a very specific area of Amundsen Gulf (Franklin Bay) during the CASES program and to opportunistic catches when deploying a multi-net sampler during CFL. An echosounder operated onboard the CCGS Amundsen continuously recorded fish echoes throughout CASES, CFL and ArcticNet expeditions. The resulting echograms were used to document the distribution of the adult stage, but in situ sampling for echo validation was only performed during CASES. Contaminant concentration and stable isotope ratios were also measured in the larval and juveniles stages collected in southeastern Beaufort Sea (Gary Stern's team). Data gaps. Knowledge about the distribution and ecology of adult marine fish in Beaufort Sea is scarce. Hydroacoustics data allowed documenting winter abundance and distribution of Arctic cod in Amundsen Gulf. However, no fish aggregation was detected the rest of the year, possibly due to a coastal and surface-related distribution. Moreover, echo validation was limited to the fish collected during CASES. Other recent US-led studies monitored the distribution of fish on the Alaskan Shelf and Slope (not detailed in this report), but basic

ArcticNet - BREA data mining project 23

biological data and distribution of adult populations of marine fish represent major gaps in the area. Information on contaminant concentrations in the adult stage and modeling-based studies is non-existent for the science programs documented in this report. Finally, no data on Inuvialuit marine fishing activities in coastal areas were reported. 4.1.7 Anadromous fish Summary. No academic-led study documenting the abundance or behaviour of anadromous fish in Beaufort Sea was conducted during the science programs detailed in section 2. However, DFO-led studies focussed on the effects of climate changes on Char collected in lakes (James Reist's team) and on mercury concentration in estuarine fish (Gary Stern's team). A previous data gaps analysis report1 also mentioned DFO-led studies on anadromous fish of the Mackenzie Delta. Data gaps. Data on anadromous fish distribution and migrations in Beaufort Sea are scarce compared to other indicators. Throughout the science programs detailed in this report, only one study documenting contaminant concentration was conducted and none analyzed stable isotopes ratios for trophic interactions. A single study was related to Inuvialuit fishing of anadromous fish and no modeling-based study was reported. 4.1.8 Marine mammals Summary. The distribution of marine mammals was monitored through long-term moored hydrophones that were deployed since 2005 by Yvan Simard's team (DFO Mont-Joli). In collaboration with Cornell University, hydrophones were also moored by ArcticNet in and around Exploration License areas (EL) 446, 449 and 451 during the 2008 and 2009 field seasons. Inuit wildlife observers were employed onboard the CGGS Amundsen to record encounters with marine mammals. Remote sensing studies and aerial surveys documenting distribution of belugas, bowhead whales and ringed seals were conducted. Finally, contaminant concentrations in belugas and ringed seals, as well as the general health situation of marine wildlife, were occasionally monitored. Only three studies documenting marine mammals harvested during Inuvialuit hunting activities in Beaufort Sea were conducted during the programs detailed in this report. Data gaps. Throughout the science programs previously mentioned, observations of marine mammal abundance were generally opportunistic rather than based on a rigorous survey. Programs documenting contaminant concentrations in marine mammals were limited to ringed seals and belugas near specific communities (mainly Ulukhaktok and Tuktoyaktuk). No study analyzing stable isotopes ratios for trophic interactions was reported and biological data were rarely collected. Information on Inuivialuit marine mammals hunting activities is also identified as a data gap due to community-based studies scarcity compared to other indicators.

ArcticNet - BREA data mining project 24

4.1.9 Noise in the environment Summary. Monitoring of ambient marine noise was limited to the hydrophones moored in southeastern Beaufort Sea (Yvan Simard's team), Deep Canada Basin and western Beaufort Sea (JWACS and JOIS programs). No study of ambient atmospheric noise was conducted throughout the science programs documented in this report. Data gaps. Apart from the moorings deployed in and around EL 446, 449 and 451 during the 2009 and 2010 field seasons, hydrophones were generally installed on mooring lines principally dedicated to physical oceanography. Consequently, no hydrophone arrays were deployed to systematically record environmental noise and vocalizations of marine mammals. As no study of ambient atmospheric noise was conducted throughout the science programs detailed in section 2, this indicator is considered as a data gap in Beaufort Sea. 4.1.10 Marine and migratory birds Summary. Knowledge about the abundance and distribution of marine and migratory birds is mostly limited to opportunistic encounters recorded by Inuit wildlife observers onboard the CCGS Amundsen. Other studies specifically focussed on breeding activities on Herschel Island, on the abundance and diversity around the Queen Elizabeth Islands, and on the Cape Parry murre colony. The health condition of King Eiders collected near Ulukhaktok was also monitored. Data gaps. As studies on birds were limited to specific populations or to opportunistic encounters during the science programs documented in this report, distribution and abundance of marine and migratory birds are considered as data gaps. Also, no study analyzing stable isotopes ratios to identify trophic interactions of birds was reported. Data related to Inuvialuit marine and migratory birds hunting were limited to two studies documenting health conditions of harvested animals. 4.1.11 Benthos Summary. The abundance and diversity of epibenthic and endobenthic fauna were regularly monitored by Alec Aitken's team (University of Saskatchewan) during CASES and by Philippe Archambault's team (UQAR) since 2007, using an Agassiz trawl and a box corer. Nutrient and chlorophyll a concentrations, bioturbation and biomarkers in the sediments were also measured since 2007. Throughout CASES, a bottom triggered camera was regularly deployed to study benthic diversity. During ArcticNet 2009 and 2010 expeditions, a camera-equipped Remotely Operated Vehicle (ROV) recorded videos of the sea bottom on specific transects. Finally, benthic community was sampled to measure contaminant concentrations throughout CASES, CFL and ArcticNet programs. (Gary Stern's team).

ArcticNet - BREA data mining project 25

Data gaps. The benthic community of the Deep Canada Basin was not documented during JWACS and JOIS programs. Studies analyzing stable isotopes ratios to identify trophic interactions in the benthic community were scarce throughout the science programs detailed in section 2. No model of the benthic community was developed. 4.1.12 Geology Summary. Bottom mapping and geological surveys were highly prioritized since 2002. The Geological Survey of Canada (Steve Blasco's team) conducted piston and box core transects for biochemistry analysis and paleoceanography on the Shelf and Slope of southeastern Beaufort Sea throughout CASES, CFL and ArcticNet programs. Sub-bottom mapping transects were conducted by the Ocean Mapping Group at the University of New-Brunswick (John E. Hughes Clarke's team) since 2004. A multibeam echosounder was concurrently operated to map the seafloor. Finally, images from the camera mounted on the ROV were used to document special features of the seafloor (e.g. mud volcanoes). Data gaps. Large-scale efforts were conducted to map and document the geotechnical characteristics of the seafloor during the science programs documented in this report, especially in Amundsen Gulf and on the Mackenzie Shelf and Slope. However, due to the CCGS Amundsen's draft, bottom and sub-bottom mapping of the coastal areas was limited to one survey onboard the Heron launch in 2006. Extensive mapping surveys of the Deep Canada Basin were conducted onboard the CCGS Louis St-Laurent and USCGC Healy throughout the United Nations Convention on Law of the Sea (UNCLOS) program (not detailed in this report). 4.1.13 Coastal erosion and longshore sediment transport Summary. Monitoring of coastal erosion and water level variations was limited to very specific areas (Herschel Island and Inuit communities) during the science programs detailed in this report. Bottom mapping of the coastal seafloor was conducted nearby Sachs Harbour onboard the Heron launch in 2006. GPS stations also monitored vertical motion of the coast and the ENVISAT satellite provided remotely-sensed images of coastal erosion. Data gaps. Throughout the science programs detailed in section 2, studies of coastal erosion and longshore sediment transport were limited to specific locations. Coastal bottom mapping data are also very limited compared to other indicators. These indicators are thus identified as data gaps. Finally, modeling of the coastal erosion was not conducted through these programs. 4.2. Science programs summary and geographical data gaps

Most of the existing data were collected in Amundsen Gulf and on the Mackenzie Shelf and Slope areas during CASES, CFL and ArcticNet expeditions. During these programs,

ArcticNet - BREA data mining project 26

oceanographic stations were defined according to the sampling activities that were conducted (e.g. full, basic, nutrients, mooring or CTD station). An example is provided in table 1.

Table 1. Deck operations that were carried out at sampling stations during Leg 4a of the Arcticnet 2009 expedition. Operations vary from one Leg to another following sampling requirements.

ArcticNet - BREA data mining project 27

Data were also collected during JWACS and JOIS expeditions (regrouped as the ''Beaufort Gyre Exploration Project'', BGEP), which focussed on the Deep Canada Basin and western Beaufort Sea. However, several indicators were not studied trough JWACS and JOIS expeditions and are consequently considered as data gaps in the Deep Canada Basin. Winter data are limited to CASES and CFL overwintering surveys, respectively conducted in Franklin Bay and Amundsen Gulf. Finally, three programs (GEOTRACES, MALINA and ARDEX) focussed on distinct indicators in specific areas. This section summarises the principal expeditions reported in this report.

4.2.1 Canadian Arctic Shelf Exchange Study (CASES) (http://www.cases.Québec-ocean.ulaval.ca/welcome_fr.asp) The CASES expedition was an international effort under Canadian leadership to understand the biogeochemical and ecological consequences of sea ice variability and changes on the eastern Beaufort Sea Shelf. In preparation for this overwintering program conducted in 2003-2004, two expeditions were conducted in fall of 2002. During the first expedition, eight lines supporting current meters and sediment traps were moored in the study area as part of the September 6 to September 24 expedition of the CCGS Sir Wilfrid Laurier. From September 22 to October 14, the second expedition completed a multidisciplinary synoptic survey of the physical and biogeochemical properties of the study area onboard the CCGS Pierre Radisson. During these 22 days, 34 scientists sampled over 110 stations covering the Mackenzie Shelf and Amundsen Gulf area (Fig. 1).30

The main thrust of the field program was the one-year (September 24, 2003 to September 09, 2004) survey of the CCGS Amundsen in Beaufort Sea. This arctic mission of unprecedented scope comprised three major parts: 1) a fall survey covering Amundsen Gulf and the Mackenzie Shelf and Slope (Fig. 2 and 3) from September to December 2003, including the recovery of the eight moorings deployed in 2002 and the deployment of 17 new mooring arrays; 2) overwintering (December 12, 2003 to June 1, 2004) of the ship in Franklin Bay for the monitoring of winter evolution of the ecosystem; and 3) spring/summer spatial survey of the region to monitor the Stamukhi Lake break-up, the opening of the Cape Bathurst Polynya and the development of the summer ecosystem, including the recovery and redeployment in August 2004 of 7 of the 17 oceanographic moorings. The annual mission of the CCCGS Sir Wilfrid Laurier to the study area was the opportunity to recover the remaining 10 moorings and to extend the sampling of the ecosystem until September 9, 2004. Overall, the CASES field program logged 543 days at sea, 377 of these days being directly chartered by CASES and 166 being contributed by national and international partners. This

ArcticNet - BREA data mining project 29

corresponded to a total of 14 544 day-scientists at sea, which made the CASES field program one of the largest and most comprehensive international effort to decipher the functioning of the Arctic Ocean shelf ecosystem and understand the biogeochemical and ecological impacts of the present decline in Arctic sea ice cover.31

CASES study area, bathymetry, and location of moorings and sampling stations (Source: Mucci et al. 2008)32 4.2.2 Circumpolar Flaw Lead (CFL) system study (http://web.mac.com/barber1818/iWeb/IPY-CFL/Welcome.html) The Circumpolar Flaw Lead (CFL) system study was a Canadian-led International Polar Year (IPY) initiative with over 350 participants from 27 countries. The study was multidisciplinary, integrating physical sciences, biological sciences and Inuvialuit traditional knowledge. The CFL study was designed to investigate the importance of changing climate processes in the flaw lead system of the northern hemisphere on the physical, biogeochemical and biological components of the Arctic marine system. The circumpolar flaw lead is a perennial characteristic of the Arctic throughout the winter season and forms when the mobile multi-year (MY) pack ice moves away from coastal fast ice, creating recurrent and interconnected polynyas in the Norwegian, Icelandic, North American and Siberian sectors of the Arctic. The CFL study was 293 days in duration and involved the overwintering of the Canadian research icebreaker CCGS Amundsen in the Cape Bathurst flaw lead throughout the annual sea-ice cycle of 2007-2008. The Beaufort Sea area was surveyed from 15 October, 2007 to August 7, 2008. Sampling was conducted in ''transect mode'' between October 18, 2007 and November 27, 2007 and 74 different open-water sites within Amundsen Gulf and southern Beaufort Sea were surveyed. The transects ran along the Mackenzie Shelf, west side of Banks Island, from

ArcticNet - BREA data mining project 31

the Mackenzie River, and along the pack ice edge (Fig. 4a). Four moorings were deployed during open-water sampling operations (Fig. 5) in collaboration with ArcticNet. On November 28, 2007, the ship entered a ''drift mode'' where it parked in a suitable ice floe until ice conditions or movement necessitated a move to another location. A suitable piece of ice consisted of an ice pan that was sufficiently large, thick, homogeneous and undisturbed, allowing researchers to set up equipment and collect samples on, over and under the ice. A total of 44 drift stations were sampled between November 28, 2007 and May 31, 2008 in northern Amundsen Gulf, south of Banks Island (Fig. 4b). Prevailing winds forced the sea ice and ship to drift along westerly vectors, in accordance with the Beaufort Gyre. Time spent at each drift site averaged 3±4 days, with the maximum duration being 22 consecutive days stationed on one floe.

Figure 4. a) Distributed open-water sample sites sampled in the fall of 2007 and the summer of 2008; b) drift stations and fast ice stations sampled in winter and spring of 2007-2008. (Source: Barber et al. 2010)33 Several fast ice sites were sampled throughout the ice melt season in May and June. The majority of these sites were located on the south side of Amundsen Gulf, at the entrance of Franklin and Darnley Bays (Fig. 4b) where a scuba diving program was conducted for sample collection. A total of 17 fast ice stations were sampled. Open-water sampling along the established transects resumed at the end of June 2008. Between June 1, 2008 and August 7, 2008 a total of 96 sites were sampled (Fig. 4a). Several transects from open water into fast ice or mobile pack ice were also conducted and many sites from the previous open-water

ArcticNet - BREA data mining project 32

season were revisited. In July 2008, four moorings were collected, serviced and redeployed33

(Fig. 5).

4.2.3 ArcticNet expeditions (http://www.arcticnet.ulaval.ca/) Since 2004, ArcticNet has been using the Canadian research icebreaker CCGS Amundsen to carry out sampling operations in the Beaufort Sea-Mackenzie Shelf-Amundsen Gulf region as part of its ongoing marine-based research program. The central aim of this research program is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Ocean. The main objective of ArcticNet’s 2005 research expedition in Beaufort Sea (September 1 to September 14) was to service and redeploy oceanographic moorings in the Amundsen Gulf-Mackenzie Shelf region. A myriad of physical, biological and geological measurements was also taken at sampling stations distributed throughout at the mouth of Amundsen Gulf (Fig. 6).

ArcticNet - BREA data mining project 33

Figure 6. Sampling stations in Beaufort Sea throughout ArcticNet 2005. Throughout ArcticNet 2006, the CCGS Amundsen surveyed the Beaufort Sea from September 30 to October 19. In addition to servicing and redeploying moorings, ArcticNet scientists sampled 44 oceanographic stations (Fig. 7). In total, over 100 ArcticNet researchers, students and technicians from twelve Canadian universities, four federal departments and two institutions from the United States were involved in the 2006 expedition.

ArcticNet - BREA data mining project 34

Figure 7. Sampling locations and cruise track of the CCGS Amundsen in Beaufort Sea throughout ArcticNet 2006. The ArcticNet 2007 expedition in Beaufort Sea started on October 15 and ended when the Amundsen reached Sachs Harbour on October 18, after servicing one mooring. This short mission was immediately followed by the CFL program. The ArcticNet 2008 expedition was conducted in the Canadian Arctic Archipelago after CFL. In 2009, sampling operations in the Beaufort Sea-Mackenzie Shelf-Amundsen Gulf region were carried out from the CCGS Amundsen from July 11 to October 14. During these 95 days, researchers sampled at over 140 oceanographic stations throughout ArcticNet (Fig. 8 and 9), GEOTRACES (Fig. 11) and MALINA (Fig. 12) programs. A total of 13 sub-surface oceanographic moorings and 12 moored hydrophones were deployed. In addition, a multitude of oceanic and atmospheric parameters were measured continuously using the Amundsen’s impressive array of continuous samplers. The ship’s EM302 multibeam sonar and Knudsen sub-bottom profiler collected over 7,000 km of high resolution bathymetry and sub-bottom data. From July 16 to July 30, the sampling effort was concentrated in and around EL 446 (Fig. 8) in collaboration with IORVL.3,4,34 In 2010, the CCGS Amundsen surveyed Beaufort Sea from August 12 to October 10 (Fig. 8 and 10). During these 59 days, researchers sampled at over 100 oceanographic stations (sediment cores and ROV stations are not shown). A total of 19 sub-surface oceanographic moorings and 12 moored hydrophones were deployed. In addition, a multitude of oceanic and atmospheric parameters were measured continuously. The ship’s EM302 multibeam sonar and Knudsen sub-bottom profiler collected over 3,500 km of high-resolution

4.2.4 IPY-GEOTRACES (http://www.geotraces.org/) The IPY-GEOTRACES program was conducted from August 27, 2009 to September 12, 2009 onboard the CCGS Amundsen. Science operations (Fig. 4) were performed to identify, characterize and quantify processes that control the distribution of key trace elements and isotopes in the global ocean and their sensitivity to changing environmental conditions. Research topics included: the supply of micronutrients to phytoplankton, contaminant dispersal in the ocean, and tracers of past and present ocean conditions. This initiative was prompted by the increasing recognition that key trace elements and isotopes are playing a crucial role as regulators and recorders of important biogeochemical and physical processes that control the structure and productivity of marine ecosystems, the dispersion of contaminants in the marine environment, the level of greenhouse gases in the atmosphere, and global climate.

4.2.5 MALINA (http://www.obs-vlfr.fr/Malina/about_us.html) The Malina oceanographic expedition was conducted onboard the Canadian research ice-breaker CCGS Amundsen from July 31 to August 24, 2009 and was led by the Laboratoire d'Océanographie de Villefranche-sur-Mer (France). The aim was to understand how changes in the ice cover, permafrost and solar radiation impact biodiversity and biogeochemical fluxes in the Arctic Ocean. In particular, in situ measurements were conducted over a network of sampling stations (Fig. 12) and compared with remotely-sensed data. In addition, underway measurements and water sampling were conducted during transit between stations.

4.2.6 ARDEX (http://www.cen.ulaval.ca/warwickvincent/ardexheader.html)

The initial sampling phase of ARDEX (Fig.13) was conducted by helicopter, from July 21 to 26, 2004. A second phase was conducted onboard the CCGS Nahidik from July 26 to August 3, 2004. ARDEX was a satellite program of CASES that allowed extending measurements into the Mackenzie River, freshwater-saltwater transition zone and delta. The primary objectives of ARDEX were to evaluate the properties of dissolved organic matter (DOM) in the river and coastal waters, and the photochemical, geochemical and biological processes regulating DOM dynamics. ARDEX data considered in the present report are limited to the Mackenzie Delta.

4.2.7 Beaufort Gyre Exploration Project (BGEP) - JWACS and JOIS (http://www.whoi.edu/beaufortgyre/index.html) The JWACS program was launched in 2002, and consisted in a scientific collaboration between Canada, the United States, Japan and China. The objective was to examine the impacts of climate variability on biological and physical ocean processes in the Canadian Basin and on Mackenzie Shelf (Fig. 14). Research topics included atmospheric science, potential environmental effects of oil and gas exploitation, physical and biological oceanography. JWACS was followed by the JOIS program in 2005, a scientific collaboration among researchers from Canada, the United States and Japan. Both programs were conducted from the CCGS Louis St-Laurent in late summer and fall.

5. Future updates

Due to time limitation, the following non-academic-led oceanographic program in Beaufort Sea was not documented in this data mining report: • The Canada's Three Ocean (C3O) program conducted during the International Polar Year (IPY) in 2007-2008 by Fisheries and Oceans Canada (DFO). A list of relevant peer-reviewed publications and technical reports published after the ESRF data mining study1 (2008) should also be provided in future updates. Principal sources to be considered (in order of priority) are: 1. The Arctic Science and Technology Information System (ASTIS) database (4000-5000 publications related to Beaufort Sea). 2. The Department of Fisheries and Oceans Canada Online Catalogue (WAVES). 3. The Canadian IPY Publication Database.

Southeastern Beaufort Sea, Amundsen Gulf

Ice-based direct observational study 2008-03-13 2008-04-24 papakyri@cc.umanitoba.ca The bail test was performed to derivate the permeability of the ice from the rate of penetration of sea water into a sac hole. After drilling a hole in the ice close to the bottom (usually between 2 and 10 cm of ice are left at the bottom), a tube was inserted into the hole and a floater is inserted into the tube. A laser, mounted on the top of the tube measured the distance between the floater (indicating the water level in the hole) and the top of the tube. The water level was increasing into the hole by addition of sea water coming through the ice. The difference between the water level at equilibrium and the water level at any time was put on a chart and the exponent of the exponential curve obtained gave the permeability.

Liver, muscle and kidney samples were analyzed for mercury concentration using cold vapour atomic absorption spectroscopy. Stable isotope analysis of 15N and 13C was carried out on lipid-removed liver and muscle samples by continuous flow, ion-ratio and mass spectrometry. Mercury and stable isotope analysis were also conducted on beluga prey species in the eastern Beaufort Sea collected in the summers of 2004 and 2006 (and earlier samples from 2002 and 2003). Fatty acid analysis was done on beluga blubber using gas chromatography. Satellite telemetry data of this beluga population (collected from satellite-linked transmitter tags on whales captured near Hendrickson Island in the summers of 1993, 1995 and 1997) was analyzed to determine habitat segregation by size, sex and reproductive status.

Ringed seals were harvested by members of the Hunters and Trappers Committee at Ulukhaktok on an annual basis. In 1993, 1995, 1996, 2002-2005, and 2007, tissue samples from 13-20 seals per year were chemically analyzed in laboratories. Additional samples from 1973 and 1977 were included in the analysis. Sex and morphometric measurements of the seals were recorded in the field. Organochlorine concentrations from blubber, including pesticides and PCBs, were analyzed with gas chromatography and electron capture detection. Mercury concentration in muscle tissues was measured by cold vapour atomic absorption spectroscopy and stable isotope ratios of nitrogen and carbon in lipid-extracted muscle tissues were analyzed by continuous flow ion ratio mass spectrometry. Sea ice parameters were measured from Canadian Ice Service ice charts.

Stable isotope analysis of 15N and 13C was carried out on lipid-removed liver and muscle samples by continuous flow, ion-ratio and mass spectrometry. Mercury and stable isotope analysis were also conducted on beluga prey species in the eastern Beaufort Sea collected in the summers of 2004 and 2006 (and earlier samples from 2002 and 2003). Fatty acid analysis was done on beluga blubber using gas chromatography. Satellite telemetry data of this beluga population (collected from satellite-linked transmitter tags on whales captured near Hendrickson Island in the summers of 1993, 1995 and 1997) were analyzed to determine habitat segregation by size, sex and reproductive status.

Ulukhaktok Lab-based (chromatography, spectroscopy, mass spectrometry analysis) and remote sensing observational study

1993-06-01 2007-06-30 Gary.Stern@dfo-mpo.gc.ca The dataset was developed to link mercury and organochlorine contaminant concentrations as well as stable isotope ratios of nitrogen and carbon in ringed seals with length of the ice-free season in the eastern Amundsen Gulf. Ringed seals were harvested by members of the Hunters and Trappers Committee at Ulukhaktok on an annual basis. In 1993, 1995, 1996, 2002-2005, and 2007, tissue samples from 13-20 seals per year were chemically analyzed in laboratories. Additional samples from 1973 and 1977 were included in the analysis. Sex and morphometric measurements of the seals were recorded in the field. Organochlorine concentrations from blubber, including pesticides and PCBs, were analyzed with gas chromatography and electron capture detection. Mercury concentration in muscle tissues was measured by cold vapour atomic absorption spectroscopy and stable isotope ratios of nitrogen and carbon in lipid-extracted muscle tissues were analyzed by continuous flow ion ratio mass spectrometry.

Morphometric measurements were recorded for each eider (mass, wing cord, head size, bill size, tarsus length). A visual estimate of body condition based on the collector's experience was also recorded. Each eider was dissected for estimation of body condition using whole body proximate composition analysis. A small sample of fat and muscle tissue was taken from the abdominal fat pad and from the breast muscle respectively prior to proximate composition analysis. Esophageal contents was reserved for identification and diet characterization. Tissue samples were used for diet characterization via fatty acid and stable isotope analysis. Proximate composition results were analyzed against morphometric analyses and observer estimates of body condition in order to evaluate their effectiveness as non-destructive estimates of body condition.
