ME70 Water Column Sonar Data Collected During DY1006

Description

Eastern Bering Sea Acoustic-Trawl Survey of Walleye Pollock (DY1006, ME70). The Midwater Assessment and Conservation Engineering (MACE) program of the Alaska Fisheries Science Center (AFSC; NOAA National Marine Fisheries Service) conducted an acoustic-trawl (AT) stock assessment survey in the eastern Bering Sea during the summer of 2010 to estimate the distribution and abundance of walleye pollock (Gadus chalcogrammus). The survey was conducted between 5 June and 7 August, 2010, along the eastern Bering Sea (EBS) shelf and in the Cape Navarin area of Russia. The survey was divided into three segments; leg 1 was 5 June to 24 June, leg 2 was 29 June to 16 July, and leg 3 was 20 July to 7 August, 2010. The survey was conducted onboard NOAA Ship Oscar Dyson, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation in addition to trawling and biological sampling capabilities. The primary instrumentation for the survey was a Simrad EK60 split-beam echosounder system utilizing five frequencies (18, 38, 70, 120, and 200 kHz) and a Simrad ME70 multibeam echosounder, with the ME70 transmit pulse synchronized to the EK60 system. This data set includes Kongsberg Simrad ME70 raw multibeam data, Seabird CTD data, and ship's navigation/oceanographic/meteorological sensor data.
