Acoustic-Trawl Survey of Walleye Pollock in the Eastern Bering Sea (DY1608, EK60)
The Midwater Assessment and Conservation Engineering (MACE) program of NOAA National Marine Fisheries Service (NMFS), Alaska Fisheries Science Center (AFSC) conducted an acoustic-trawl (AT) stock assessment survey on the eastern Bering Sea shelf during late spring/summer of 2016 to estimate the distribution and abundance of walleye pollock (Gadus chalcogrammus). The survey was conducted 12 June to 17 August aboard NOAA Ship Oscar Dyson, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation. The vessel departed Dutch Harbor, Alaska on 12 June and returned to Dutch Harbor on 17 August. The cruise was completed in three legs (leg 1, 12 June to 3 July; leg 2, 7-25 July; leg 3, 29 July to 17 August), with all port calls in Dutch Harbor, Alaska.
