The survey is carried out during February-early March, and covers the main cod distribution area in the Barents Sea. The coverage is in some years limited by the ice distribution. Three vessels are normally applied, two Norwegian and one Russian. The main observations are made with bottom trawl, pelagic trawl, echo sounder and CTD. Plankton studies have been done in some years. Cod and haddock are the main targets for this survey.
Swept area indices are calculated for cod, haddock, Greenland halibut, S. marinus and S. mentella. Acoustic observations are made for cod, haddock, capelin, redfish, polar cod and herring. The survey started in 1981.
