EK60 Water Column Sonar Data Collected During DY1603

Description

Southeastern Aleutian Basin (Bogoslof Island) Acoustic-Trawl Survey of Walleye Pollock (DY1603, EK60). The Midwater Assessment and Conservation Engineering (MACE) program of NOAA National Marine Fisheries Service (NMFS), Alaska Fisheries Science Center (AFSC) conducted acoustic-trawl (AT) stock assessment surveys in the Bogoslof Island area of the southeastern Aleutian Basin during late winter of 2016 to estimate the distribution and abundance of walleye pollock (Gadus chalcogrammus). The surveys were conducted 4-8 March, departing from Kodiak, Alaska (2 March) and included the Umnak and Samalga Pass area. The vessel returned to the Kodiak, Alaska area on 13 March to exchange scientific personnel and depart for the following cruise (Gulf of Alaska/Shelikof Strait survey, 14-21 March, cruise DY1604). The survey was conducted aboard NOAA Ship Oscar Dyson, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation.
