    • EK60 Water Column Sonar Data Collected During OD0606

    Metadata Updated: June 9, 2023

    AFSC Inter-Vessel Comparison of NOAA Ships Oscar Dyson and Miller Freeman on the Eastern Bering Sea Shelf (OD0606, EK60). The Midwater Assessment and Conservation Engineering (MACE) program of NOAA National Marine Fisheries Service (NMFS), Alaska Fisheries Science Center (AFSC) conducted an inter-vessel acoustic-trawl (AT) comparison of NOAA Ships Oscar Dyson and Miller Freeman on the eastern Bering Sea shelf 3-14 July 2006. The inter-vessel comparison was conducted aboard NOAA Ship Oscar Dyson, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation. The vessel is equipped with a Simrad EK60 split-beam echosounder system utilizing five frequencies (18, 38, 70, 120, and 200 kHz). The vessel departed Kodiak, Alaska on 3 July and arrived in Dutch Harbor, Alaska on 14 July. EK60 echosounder systems on the Dyson were calibrated in Three Saints Bay, Kodiak Island, Alaska on 3 July with a follow-up post-cruise calibration conducted in Captains Bay, Dutch Harbor, Alaska on 14 July.", "metadata_author
