Shumagin Islands Acoustic-Trawl Survey of Walleye Pollock (DY1001, 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 Gulf of Alaska (GOA) during
late winter of 2010 to estimate the distribution and abundance of walleye pollock
(Gadus chalcogrammus). The survey was conducted between 22 February and 9 March, 2010,
and included the Shumagin Islands, Sanak Trough, Morzhovoi Bay, Kenai Peninsula bays,
Prince William Sound, and Marmot Bay. The survey was conducted onboard NOAA Ship
Oscar Dyson, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation
in addition to 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/meterological
sensor data.
