Trawl Catch and Species Abundance data from the 2020 Gulf of Alaska International Year of the Salmon Expedition

This dataset contains fish species abundance data and species-specific biometrics data collected in the Northeast Pacific Ocean using a midwater trawl net (the NPAFC 1142 research trawl net with a 3 mm cod end mesh size). These data were collected as part of the International Year of the Salmon (IYS) Gulf of Alaska High Seas Expedition conducted in March and April 2020, to further improve the understanding of factors impacting salmon early marine winter survival.
