Directory entires that have specified Chukchi Sea as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

1. Alaska Fisheries Science Center surveys

The Alaska Fisheries Science Center (AFSC), under NOAA’s National Marine Fisheries Service (NMFS) is responsible for the development and implementa¬tion of NOAA’s scientific research on living marine resources in Alaskan waters. Research addresses more than 250 fish and 42 marine mammal stocks dis¬tributed on the US continental shelf and in adjacent pelagic waters. Twenty-seven commercially-important fish and crab stocks are assessed annually. The study of the effects of climate change on marine resources evidenced by loss of sea ice and ocean acidification in the Bering and Chukchi seas is a key research area. The AFSC leads a suite of fisheries research and assessment cruises in the Gulf of Alaska, Aleutian Islands and Bering Sea, which include: 1. Annual eastern Bering Sea shelf bottom trawl survey 2. Biennial (even number years) survey, eastern Bering Sea 3. Biennial (even number years) bottom trawl survey, Aleutian Islands 4. Biennial (even number years) summer Pollock survey, eastern Bering Sea shelf 5. Annual winter Aleutian basin Pollock survey 6. Annual winter Shumagin Islands Sanak Trough Pollock survey 7. Annual winter Shelikof Strait Pollock survey 8. Annual sable fish longline survey 9. Bering-Aleutian Salmon International Survey extended to the Chukchi Sea and the Eastern Bering Sea Shelf (BASIS).BASIS is a gridded fisheries oceanography survey that includes CTD and NPZ observations in addition to catches from epipelagic (0-20m) trawls. The AFSC is expanding marine fish survey effort in the Arctic Ocean, including: 1. Beaufort Sea Marine Fish Survey planned for August 2008, a cooperative project of NOAA, UA, UW and MMS (providing funding); 2. Inter-tidal and sub-tidal Marine Fish and Habitat (“ShoreZone”) Surveys near Point Barrow (Beaufort and Chukchi Seas) in 2006 and 2008; and 3. Chukchi Sea Marine Fish Survey, an extension of BASIS possible for August 2008, contingent on NOAA ship availability.

2. NASA Ice monitoring

NASA satellites (Figure 13) and numerous instruments provide high accuracy, stable, circum-Arctic measurements for ocean and sea ice observing, including surface vector winds over the ice-free ocean, sea surface temperature, marine phytoplankton and sea ice temperature. The NASA satellites and ocean and sea ice data sets include: 1. Passive microwave time series of sea ice extent begin in 1978 and are archived at NSIDC. 2. The major Synthetic Aperture Radar (SAR) time series is from the Canadian RADARSAT satellite launched in 1995. RADARSAT data of the Arctic Ocean are processed by the RGPS (RADARSAT Geophysical Processing System, yielding high-resolution charts of ice motion, age/thickness and deformation. All RGPS data are archived at the NASA-supported Alaska Satellite Facility (ASF), University of Alaska Fairbanks. 3. GRACE is a joint NASA/German mission that measures the changes in gravity associated with the changing mass of the ocean, land, and ice sheets. In experimental measurements, GRACE has measured the changes of mass associated with the shift of ocean currents in the Arctic Ocean. 4. The ICESat satellite is in a high latitude orbit (86°N) and can determine the free surface height of the Arctic Ocean up to that latitude. These laser measurements can be used to determine the geostrophic flow. ICESat also measures the height of the snow/air interface of the sea ice, which can be used to estimate sea ice thickness when combined with other data, e.g., snowfall and ice motion, or radar altimeter measurements of the sea ice freeboard. 5. Sea surface temperature (SST) and ice surface temperature (IST) are measured by NASA with the MODIS instrument aboard the Aqua and Terra satellites. The AMSR-E instrument on Aqua measures all-weather sea surface temperature. The follow-on instrument to MODIS is the Visible Infrared Imaging Radiometer Suite (VIIRS), scheduled for launch in 2010 on NPP (NPOESS Preparatory Project). The NPP follow-on satellite is the NPOESS (National Polar-orbiting Environmental Satellite System) series beginning in 2013. 6. Satellite-derived ocean color is used in combina-tion with environmental data to provide primary productivity. NASA currently provides ocean color from observations taken by the MODIS instrument on Aqua. Under present plans, the MODIS replacement is VIIRS on the NPP and NPOESS satellites. Because VIIRS on NPP is not expected to yield the same high quality of ocean color measurements as MODIS, there may be a gap in the high accuracy of these measurements.

3. Application of High-Frequency Radar to Potential Hydrocarbon Development Areas in the Northeast Chukchi Sea: Physical Oceanography of the Chukchi Sea OCS

Understanding the physical oceanography of the northeast Chukchi Sea through the collection of real time High Frequency Radar (HFR) surface current measurements from shore-based systems, deployment of sub-surface Acoustic Doppler Current Profilers (ADCP), and the use of Automated Underwater Vehicles (AUV). Providing oceanographic data sets for guiding the development and evaluation of ocean circulation, wave and oil spill trajectory models.

4. Submarine Operational And Research Environmental Database (SOARED)

The Submarine Operational And Research Environmental Database (SOARED)is comprised of a fixed relational environmental database using unclassified data collected during the Science Ice Exercises (SCICEX) during the past several years. It also includes publicly accessible gridded historical sound velocity, temperature and salinity data from 1900 from the US National Oceanographic Data Center. This project is a demonstration system to show ways to retrieve and analyze sound velocity, temperature and salinity profiles, bathymetry and ice thickness data using a mouse-driven GIS-based query.

5. Expedition of hydrographical vessel 'Nikolai Kolomeets'

The expedition by vessel 'Nikolai Kolomeets'included sampling of marine water, bottom sediments, benthos and plankton for studies of accumulation and transformation of OCs and estimation of related toxic effects on aqueous biocenoses. The marine studies took place during the period July-October 2000 in areas of the Pechora, Kara, Laptev, East-Siberian and Chukchi Seas.
