High concentrations of phosphate were measured in the surface water of the southern Baltic. Silicate concentrations were also enhanced while nitrogen showed normal values. On the West-Coast nutrients concentrations, except for silicate, were normal or close to normal. Silicate concentrations in the Skagerrak were higher than normal for the season. The spring bloom in the Skagerrak coastal areas and in the Kattegatt were just at the beginning, while winter conditionsprevailed in the Baltic. In the Baltic Proper oxygen concentrations were below 2 ml/l at depths exceeding 80 metres. Hydrogen sulphide was found in the eastern, northern and western Gotland Basin.
