Pelagic Trawl Fish Dataset, Arctic Integrated Ecosystem Research Program, June 2018

These data are part of the ASGARD component of the Arctic Integrated Ecosystem Research Program (IERP), sponsored by the North Pacific Research Board (NPRB), Collaborative Alaskan Arctic Studies Program (formerly the North Slope Borough/Shell Baseline Studies Program), Bureau of Ocean Energy Management (BOEM), and the Office of Naval Research Marine Mammals and Biology Program. To investigate the dynamics of the spring season in the northeastern Chukchi Sea, we conducted trawl surveys in June 2017 to explore fish abundance and life history parameters. Demersal fishes were targeted with a 3 m plumb-staff beam trawl, while pelagic fishes were targeted using an Isaacs-Kidd midwater trawl. Catches were processed (see methods).
