EK60 Water Column Sonar Data Collected During OD0703

Description

AFSC Inter-Vessel Comparison of NOAA Ships Oscar Dyson and Miller Freeman in the Bogoslof Island Area (OD0703, 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 comparison of NOAA Ships Oscar Dyson and Miller Freeman in the Bogoslof Island area of Alaska 1-10 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 1 March and arrived in Dutch Harbor on 10 March. The EK60 echosounder system was calibrated at the start of the cruise in Captains Bay, Dutch Harbor and again at the end of the cruise in Portage Bay (Makushin Bay), Unalaska Island, Alaska on 10 March.
