Metadata Updated: February 8, 2018

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 the winter of 2012 to estimate the distribution and abundance of walleye pollock (Theraga chalcogramma). The surveys were conducted 5-15 March, departing from Kodiak, Alaska (4 March) and returning to Kodiak at the end of cruise DY1203 on 27 March; an intermediate personnel transfer was conducted in Kodiak on 19 March. The surveys were conducted aboard NOAA Ship Oscar Dyson, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation.
