A new agreement with the Swedish Coastguard meant that only the Swedish west coast and south western Baltic Proper (Arkona and Bornholm Basins) were sampled. In Skagerrak and Kattegat, nutrient conditions were normal for the season. In the south western parts of the Baltic Proper concentrations of phosphate and silicate were still high, while inorganic nitrogen showed normal values. Plankton activity was low in all areas. Oxygen concentrations below 2 ml/l (hypoxia) were found at depth exceeding 60 metres in the Bornholm Basin as well as in the Hanö Bight.
