The Resource Assessment and Conservation Engineering (RACE) Division of the National Oceanic and Atmospheric Administration’s (NOAA) Alaska Fisheries Science Center (AFSC) conducted the Eastern Bering Sea Continental Shelf Bottom Trawl Survey of Groundfish and Invertebrate Resources from May 31, 2017 to August 07, 2017. This cruise continued the annual series of eastern Bering Sea crab and groundfish stock assessment surveys, which began in 1971. The survey covered the Bering Sea shelf between the depths of 20 and 200 m from Bristol Bay northward to latitude 62° N.

The Resource Assessment and Conservation Engineering (RACE) Division of the National Oceanic and Atmospheric Administration’s (NOAA) Alaska Fisheries Science Center (AFSC) conducted the Eastern Bering Sea Upper Continental Slope Bottom Trawl Survey of Groundfish and Invertebrate Resources from May 31 to August 10, 2016. This cruise continued the biennial series of eastern Bering Sea slope crab and groundfish stock assessment surveys, which began anew in 2002. The 2016 EBSS trawl survey is the sixth in this series of biennial groundfish surveys that incorporate the AFSC’s latest sampling technologies and protocols for survey design, catch data gathering, species identification, and net mensuration monitoring. The new standard survey covered the Bering Sea slope between the depths of 200 and 1200 m from Unimak Pass to the international date-line in Navarin Canyon.

The survey covered the Bering Sea shelf between the depths of 20 and 200 m from Bristol Bay northward to latitude 62° N.

The Resource Assessment and Conservation Engineering (RACE) Division of the National Oceanic and Atmospheric Administration’s (NOAA) Alaska Fisheries Science Center (AFSC) conducted the Eastern Bering Sea Continental Shelf Bottom Trawl Survey of Groundfish and Invertebrate Resources from May to July, 2008. This cruise continued the annual series of eastern Bering Sea crab and groundfish stock assessment surveys, which began in 1971. The survey covered the Bering Sea shelf between the depths of 20 and 200 m from Bristol Bay north to a latitude of 62° N.

The 2012 Eastern Bering Sea Upper Continental Slope survey was designed to sample the entire upper slope region from 200-1200 meters using a stratified random design. The goal was to distribute sampling effort in proportion to the survey area by depth and subarea. The survey area was divided into 6 physical subareas running south to north (1-6, Figure 1) that may represent distinct biological realms such as canyon areas (2, 4), steep rough slope areas (3,5) and broad gentle sloping areas (1, 6). Each subarea was further divided into five depth strata each covering approximately 200 meters in depth from 200-1200 meters. Table 2 shows the five depth strata, target depth ranges for each stratum, and the area and percentage each depth stratum represented.
