This was a multi-year project which follows earlier studies of long-term bottom trawling impacts in the same general region. The study area was within the Crab and Halibut Protection Zone 1 in Bristol Bay (management area 512; approximately latitude 58 degrees north and longitude 160 degrees west. In general, at-sea work was divided into three phases: (1) integrated biological and geological sampling before experimental trawling, (2) experimental trawling and (3) integrated biological and geological sampling after experimental trawling. Survey activities were conducted aboard the 47.2 meter (155 ft) chartered vessel Ocean Explorer. This was a commercial fishing vessel modified to support the research activities. Activity during phase 1 consisted of side scan assessments of seafloor morphology with an interferometric Klein 5410 side scan sonar towfish during night wheel watches, and epifauna trawls and collection of infauna and sediment grabs during daylight hours. All samples from a particular gear were collected in succession, so as to minimize time spent installing and configuring gear during phases (1) and (3). Assessment activities after the impact phase were a repeat of activities prior to experimental trawling. The research objectives address Congressional mandates (Magnuson-Stevens Fishery Conservation and Management Act of 1996) to investigate potential adverse impacts of fishing gear on essential fish habitats. The primary objectives of this study were to determine if bottom trawls have measurable and significant effects on soft-bottom habitat in the eastern Bering Sea and if so, are there fundamental changes that define a new recovery state. completed McConnaughey, Bob bob.mcconnaughey@noaa.gov pointOfContact McConnaughey, Bob bob.mcconnaughey@noaa.gov email custodian BACI design acoustic sediment classification side scan sonar trawl impact theme Bering Sea 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.
