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 13 stations where complete hydrography were sampled, and 12 stations with only CTD. In the Kattegat area 11 stations were sampled with CTD and bottle samples, and 11 stations with only CTD.

During the expedition one of the monitoring stations, Anholt E in southern Kattegat, was sampled. The sea surface temperature was normal for the season. Concentrations of nutrients were slightly below normal.

Oxygen concentrations in the bottom water of the investigated areas were good and varied from 5.7 to 6.7 ml/l.
