The map shows the sampling grid for the eastern and northern Bering Sea shelf bottom trawl survey (June 1 and Aug ). The map will be updated several times each week to show the progress of the survey vessels and the bottom temperature (°C) in each 20x20 nautical mile grid cell.

The pool we do experience is “The cold pool,” which is actually a large mass of frigid water near the bottom of the eastern Bering Sea shelf with a temperature less than 2°C (36°F). We are able to get a snapshot of the cold pool each summer because our survey covers the entire eastern Bering Sea shelf. The eastern Bering Sea bottom trawl survey has been conducted annually since by the Resource Assessment and Conservation Engineering Division of .

The climate regime in the eastern Bering Sea has recently been dominated by a pattern of multi-year stanzas, in which several successive years of minimal sea-ice formation and warm summer temperatures (e.g., –, –) alternate with several years of relatively extensive sea-ice formation and cold summer temperatures (e.g., –). Book. Full-text available Out of 10, casts from the eastern Bering Sea continental shelf during –, 7, (%) passed quality control checks. Results of the Eastern and. The eastern Bering Sea bottom trawl survey has been conducted annually since by the Resource Assessment and Conservation Engineering Division of the Alaska Fisheries Science Center, National Marine Fisheries Service.   The National Oceanic and Atmospheric Administration׳s (NOAA) Alaska Fisheries Science Center bottom trawl survey samples demersal fish at over sites on the eastern Bering Sea continental shelf each summer on a 37×37 km 2 grid. Rugged conductivity–temperature-depth sensors (CTDs) were added to the net hauls to obtain gridded data sets of temperature and salinity .

The surveys sample depths from 10 m near the mainland to about m near the shelf break and divide the survey area into 37×37 km grid blocks with a sampling location at.
