The report presents cruises carried out by the research vessels "G.O. Sars". "Johan Hjort", "Håkon Mosby",
"G.M. Dannevig", ''Jan Mayen" / "Helmer Hanssen" and some hired commercial fishing vessels on behalf of the
Institute of Marine Research and the University of Bergen during 2011. The charts mainly show CTD and trawl
stations, but some charts also include plankton stations. Beside tracks and stations, standard sections observed
are listed. A separate table lists the number of observations per month for the fixed stations along the Norwegian
coast. The cruises are reported to the International Council for the Exploration of the Sea (ICES) in the "Cruise
Summary Report". The data may be requested from the Norwegian Marine Data centre at the Institute of Marine
Research.
