EK60 Water Column Sonar Data Collected During OD0501
Acoustic-Trawl Survey of Walleye Pollock in the Gulf of Alaska (OD0501, EK60). The Midwater Assessment and Conservation Engineering (MACE) program of NOAA National Marine Fisheries Service (NMFS), Alaska Fisheries Science Center (AFSC) conducted an acoustic-trawl (AT) stock assessment survey of walleye pollock (Theraga Chalcogramma) along sections of the Gulf of Alaska shelf and shelfbreak from the Islands of Four Mountains to south of Prince William Sound, 30 June to 30 July 2005. The survey was conducted aboard NOAA Ship Oscar Dyson, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation, utilizing a Simrad EK60 split-beam echosounder system. The vessel departed Kodiak, Alaska on 2 July and arrived in Kodiak on 29 July. The cruise was completed in two legs with a port call in Dutch Harbor, Alaska 12-13 July. The EK60 echosounder system was calibrated at the start of the cruise in Three Saints Bay, Kodiak Island, Alaska on 2 June, and at the end of the cruise in Three Saints Bay on 28 July 2005.
