The Midwater Assessment and Conservation Engineering (MACE) program of NOAA Fisheries, Alaska Fisheries Science Center (AFSC) conducted acoustic-trawl (AT) stock assessment surveys in the Gulf of Alaska (GOA) during the winter and early spring of 2017 to estimate the distribution and abundance of walleye pollock (Gadus chalcogrammus). These surveys were conducted aboard NOAA Ship Oscar Dyson, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation. The primary instrument for the surveys was a Simrad EK60 split-beam echosounder system utilizing five frequencies (18, 38, 70, 120, and 200 kHz). The vessel departed Kodiak, Alaska on 1 March and conducted the Kenai Bays survey (including Port Dick, Nuka Passage, Harris Bay, Aialik Bay, Resurrection Bay, Day Harbor, and Port Bainbridge) 2-5 March. The Prince William Sound, Hinchinbrook Trough and Middleton Island surveys were conducted 5-9 March. A calibration of the echosounder system was conducted during the previous cruise on 14 February in Volcano Bay, Alaska. The vessel arrived at its homeport of Kodiak, Alaska on 10 March, 2017.\r\n \r\n \r\n Acoustic-trawl (AT) surveys of walleye pollock (Gadus chalcogrammus) in the Kenai Bays and Prince William Sound areas of the Gulf of Alaska, 1-10 March, 2017.\r\n \r\n \r\n completed\r\n \r\n \r\n \r\n \r\n NOAA National Centers for Environmental Information\r\n \r\n \r\n \r\n \r\n \r\n \r\n ncei.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/contact\r\n \r\n \r\n NCEI Contact Information\r\n \r\n \r\n Information for contacts at NCEI.\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n pointOfContact\r\n \r\n \r\n \r\n \r\n \r\n \r\n NOAA National Centers for Environmental Information\r\n \r\n \r\n Water Column Sonar Data Manager\r\n \r\n \r\n \r\n \r\n \r\n \r\n (303) 497-4742\r\n \r\n \r\n \r\n \r\n \r\n \r\n 325 Broadway, Mail Code E/NE42\r\n \r\n \r\n Boulder\r\n \r\n \r\n CO\r\n \r\n \r\n 80305-3328\r\n \r\n \r\n USA\r\n \r\n \r\n wcd.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n pointOfContact\r\n \r\n \r\n \r\n \r\n \r\n \r\n notPlanned\r\n \r\n \r\n \r\n \r\n \r\n \r\n Earth Science > Oceans > Ocean Acoustics > Acoustic Scattering\r\n \r\n \r\n Earth Science > Oceans > Aquatic Sciences > Fisheries\r\n \r\n \r\n Earth Science > Oceans > Ocean Acoustics\r\n \r\n \r\n Earth Science > Biosphere > Ecosystems > Marine Ecosystems > Pelagic\r\n \r\n \r\n Earth Science > Biosphere > Ecosystems > Marine Ecosystems\r\n \r\n \r\n Earth Science > Biosphere > Ecosystems > Marine Ecosystems > Benthic\r\n \r\n \r\n Earth Science > Biosphere > Ecosystems > Aquatic Ecosystems\r\n \r\n \r\n Earth Science > Oceans > Bathymetry/Seafloor Topography > Bathymetry\r\n \r\n \r\n Earth Science > Oceans > Bathymetry/Seafloor Topography > Seafloor Topography\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Science Keywords\r\n \r\n \r\n \r\n \r\n 2020-01-09\r\n \r\n \r\n publication\r\n \r\n \r\n \r\n \r\n 9.1\r\n \r\n \r\n \r\n \r\n NASA Goddard Space Flight Center, Earth Science Data and Information System\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.earthdata.nasa.gov/learn/find-data/idn/gcmd-keywords\r\n \r\n \r\n Global Change Master Directory (GCMD) Keywords\r\n \r\n \r\n The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.
