Dataset Overview | National Centers for Environmental Information (NCEI)

Water temperature, salinity, and others taken by trawl-mounted CTD from chartered fishing vessels during the 2021-2023 Alaska Fisheries Science Center Eastern and Northern Bering Sea Annual Summer Bottom Trawl Surveys (NCEI Accession 0286094)

Preview graphic

This dataset contains water column profile and bottom data taken by trawl-mounted CTD during the 2021-2023 in the Eastern and Northern Bering Sea during summer bottom trawl surveys conducted by the NOAA Fisheries/Alaska Fisheries Science Center/Resource Assessment and Conservation Engineering Division/Groundfish Assessment Program. Data include temperature, salinity, density, depth, pressure, sound speed, and buoyancy frequency. The data types are digital numeric in a netCDF file.
