Alaska Groundfish Tagging Map

The NOAA Fisheries has been tagging and releasing groundfish in Alaska waters since 1972. In that time, approximately 452,000 tags have been released and over 36,000 have been recovered.

Alaska Groundfish Age-Length Map Tool

The Alaska Fisheries Science Center collects a variety of biological information during its fisheries surveys. This tool provides information on the ages and locations of fish caught during various years (1980-2015) of our groundfish trawl and acoustic surveys along the Alaska shelf.

Alaska Longline Survey Data Map

The Alaska Fisheries Science Center (AFSC) conducts annual longline surveys to estimate the relative abundance of major groundfish species on the continental slope of the eastern Bering Sea, Aleutian Islands, and the Gulf of Alaska. The survey is primarily designed to assess sablefish and indices of abundance have been computed since 1979. Catch data from other species are also available. From 1979 to 1994, the AFSC conducted cooperative annual longline surveys with Japan, and then independently from 1987 to present.

Alaska Bathymetry Map

Bathymetry data can be analyzed to provide important information (e.g., slope and roughness) for defining Essential Fish Habitat. This mapping tool contains bathymetry data compiled by the Alaska Fisheries Science Center's Groundfish Assessment Program from the Aleutian Islands, Cook Inlet, the Central Gulf of Alaska and Norton Sound in Alaska.

Steller Sea Lion Field Season Map

Every year, biologists from the Alaska Fisheries Science Center Marine Mammal Laboratory survey the endangered Steller sea lion during the summer months in Alaska. This map provides a compilation of information collected during the 2016 field season, which included surveys via air, vessel and remote field camps.
