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 and 12 stations with complete hydrography were sampled, 3 ordinary SMHI stations were sampled due to a storm during the SMHI cruise earlier in January. In the Kattegat area 12 stations were sampled with complete hydrography. The spring bloom had not started in the investigated area. Nutrients in the area showed concentrations normal for the season. Oxygen conditions in the bottom waters of the investigated areas were good and many stations showed values over 90% saturation.
