Raw acoustic data was logged continuously 24 hours/day for each of the four legs of the cruise. The data is stored as raw files on the AFSC network drive. Acoustic data collection in conjunction with bottom trawling operations allows us to address several difficulties in obtaining representative trawl samples such as: searches for trawlable location over untrawlable ground, seafloor characterization at abandoned stations, mapping seafloor areas without adequate NOS charting, and quantifying schools of off-bottom fish. underDevelopment Von Szalay, Paul paul.von.szalay@noaa.gov pointOfContact Von Szalay, Paul paul.von.szalay@noaa.gov custodian annually habitat,groundfish surveys,hydroaccoustic,time series,trawl, theme summer temporal Alaska,Aleutian Islands,Gulf of Alaska,Eastern Bering Sea Shelf place DOC/NOAA/NMFS/AFSC > Alaska Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
