Summary
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 13 stations with complete hydrography were sampled. In the Kattegat area 12 stations were sampled with ctd and bottle sample. High concentrations of nutrient were measured at 7.5N Hirtshals and 4.5N Skagen probably an influence of the Jutland current. The spring bloom had not started in the investigated area. Oxygen conditions in the bottom waters of the investigated areas were good and many stations showed values over 90% saturation throughout the water column.
