Cruise and backscatter data processing report for the 2018 Gulf of Alaska trawlability study (GOATS)

This study investigates the utility of mission-appropriate hydrographic technology and advanced acoustic-processing methods to statistically discriminate T and UT habitats in the Gulf of Alaska (GOA) bottom-trawl survey area. Five selected “blocks”, or groups, of stations were chosen to ensure efficient use of ship time and to cover areas that represent depths and slopes commonly encountered during the NMFS bottom-trawl survey. Additionally, International Hydrographic Organization quality bathymetry data were acquired and delivered for nautical chart updates thoughout the study area. 2020 NMFS (National Marine Fisheries Service) AFSC (Alaska Fisheries Science Center) Submitted https://doi.org/10.25923/hx3s-sn20 Public Domain 1861
