The expedition was included within SLU:s International Bottom Trawl Survey and covered the Skagerrak and the Kattegat.

Mapping of winter nutrient conditions was performed in the Skagerrak at 11 stations where complete hydrography were sampled, and 10 stations with only CTD. In the Kattegat area 14 stations were sampled with CTD and bottle samples, and 10 stations with only CTD.

During the expedition one of the monitoring stations, Anholt E in southern Kattegat, was sampled. The sea surface temperature was above normal for the season. Concentrations of silicate and phosphorus were above normal for the season, and concentrations of dissolved inorganic nitrogen were normal for the season.

Oxygen concentrations in the bottom water of the investigated areas were good and aried from 4.3 to 6.8 ml/l.
