Scientists of the Groundfish Assessment Program of Alaska Fisheries Science Center's Resource Assessment and Conservation Engineering (RACE) Division conducted the tenth biennial groundfish assessment survey of the Gulf of Alaska during the summer of 2017. These surveys extend to 15 the series of surveys, previously conducted every 3 years between 1984 and 1999, which constitute the time series used in stock assessments of Gulf of Alaska groundfish resources. The survey area covered the continental shelf and upper continental slope to 700 m in the Gulf of Alaska from Islands of Four Mountains (170° W long.) and continued eastward approximately 2,800 km across the Gulf of Alaska to Dixon Entrance (133° 25' W long.). The survey was conducted aboard two chartered commercial trawlers, the FV Ocean Explorer and the FV Sea Storm. Trawl haul samples were successfully collected at 536 survey stations using standard RACE Division Poly Nor'Eastern high-opening bottom trawl nets with rubber bobbin roller gear.

Scientists of the Groundfish Assessment Program of Alaska Fisheries Science Center's Resource Assessment and Conservation Engineering (RACE) Division conducted the seventh biennial groundfish assessment survey of the Gulf of Alaska during the summer of 2011. These surveys extend the series of surveys, previously conducted every 3 years between 1984 and 1999, which constitute the time series used in stock assessments of Gulf of Alaska groundfish resources. The survey area covered the continental shelf and upper continental slope to 700 m in the Gulf of Alaska from Islands of Four Mountains (170° W long.) and continued eastward approximately 2,800 km across the Gulf of Alaska to Dixon Entrance (133° 25' W long.). The survey was conducted aboard two chartered commercial trawlers, the FV Ocean Explorer and the FV Sea Storm. Trawl haul samples were successfully collected at 670 survey stations using standard RACE Division Poly Nor'Eastern high-opening bottom trawl nets with rubber bobbin roller gear.

The eleventh in a series of comprehensive bottom trawl surveys of groundfish resources in the Gulf of Alaska (GOA) region was conducted from May 18 through July 31, 2009, by the Resource Assessment and Conservation Engineering (RACE) Division of the Alaska Fisheries Science Center (AFSC), Seattle, Washington. Since 1999 this survey has been conducted biennially; earlier surveys were conducted triennially between 1984 and 1999.

The tenth in a series of comprehensive bottom trawl surveys of groundfish resources in the Gulf of Alaska (GOA) region was conducted from May 25 through August 7, 2007, by the Resource Assessment and Conservation Engineering (RACE) Division of the Alaska Fisheries Science Center (AFSC), Seattle, Washington. Since 1999 this survey has been conducted biennially; earlier surveys were conducted triennially between 1984 and 1999.

The third biennial bottom trawl survey of Gulf of Alaska (GOA) groundfish resources was conducted from May 20 through August 9, 2003, by the Resource Assessment and Conservation Engineering (RACE) Division of the Alaska Fisheries Science Center (AFSC), Seattle, Washington. The standard biennial GOA survey area, established in 1999, stretches from the U.S.-Canada border at Dixon Entrance (54° 30' N latitude) to the Islands of the Four Mountains at the base of the Aleutian Islands (170° W longitude) including depths from approximately 10 to 1,000 m. The entire standard area was surveyed in 1999. Due to conflicting commitments in 2001, only the area west of 147° W longitude and depths to 500 m were surveyed that year. Although sufficient time and resources were available to survey the entire standard area in 2003, none of the vessels were equipped to fish as deep as 1,000 m. Consequently, hauls in the deepest strata (700-1,000 m) were eliminated from this year's survey design.

The ninth in a series of comprehensive bottom trawl surveys of groundfish resources in the Gulf of Alaska (GOA) region was conducted from May 18 through August 6, 2005, by the Resource Assessment and Conservation Engineering (RACE) Division of the Alaska Fisheries Science Center (AFSC), Seattle, Washington. Since 1999 this survey has been conducted biennially; earlier surveys were conducted triennially between 1984 and 1999.

Scientists of the Groundfish Assessment Program of Alaska Fisheries Science Center's Resource Assessment and Conservation Engineering (RACE) Division conducted the ninth Gulf of Alaska Biennial Bottom Trawl Survey during the summer of 2015. This survey extends to 13 the series of surveys, previously conducted every 3 years between 1984 and 1999, which constitute the time series used in stock assessments of Gulf of Alaska groundfish resources. The survey area covered the continental shelf and upper continental slope to 1,000 m in the Gulf of Alaska from Islands of Four Mountains (170°W long.) and approximately 2,800 km across the Gulf of Alaska to Dixon Entrance (133°25'W long.). The survey was conducted aboard three chartered commercial trawlers, the FV Alaska Provider, FV Sea Storm, and FV Cape Flattery. Trawl haul samples were successfully collected at 772 survey stations using standard RACE Division Poly Nor'Eastern high-opening bottom trawl nets with rubber bobbin roller gear.
