EK60 Water Column Sonar Data Collected During OD0704
AFSC Inter-Vessel Comparison of NOAA Ships Oscar Dyson and Miller Freeman in the Shelikof Strait Area (OD0704, 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 in the Shelikof Strait area of the Gulf of Alaska 11-25 March 2007. The inter-vessel comparison 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 equipped with five frequencies (18, 38, 70, 120, and 200 kHz). The vessel departed Dutch Harbor, Alaska on 11 March and arrived in Kodiak, Alaska 25 March. The EK60 echosounder system was calibrated at the end of the previous cruise in Portage Bay (Makushin Bay), Unalaska Island, Alaska on 10 March and a final system calibration was conducted in Uyak Bay, Kodiak Island, Alaska on 23 March.
