Surface temperatures varied between 9 and 12 degrees C. Nutrient concentrations were normal for the season in all areas. Hydrogen sulphide was found at depths greater than 120-140 meters.

Surface temperatures varied between 15.2 and 16.8 degrees C. Nutrient concentrations were normal for the season in almost all areas. High fluorescence values were measured at the Å section in the Skagerrak, as well as in the northern part of the Sound. Hydrogen sulphide was found at depths greater …

Low oxygen concentrations were found in the bottom water at Lundåkrabukten 1.95 ml/l and Skälderviken 1.51 ml/l. In the south east parts of Kattegatt the oxygen concentrations varied between 2.3 to 3.0 ml/l.

During the expedition, the weather was mainly calm and sunny. The surface water temperatures were between 14.8-18.9°C in the whole area. Oxygen concentrations below 2 ml/l were found at depths greater than 70m in the Bornholm Basin, at the Landsort and the Karlsö Deep, greater than 80 m in the …

Nutrient conditions were normal for the season. Hydrogen sulphide was found in the deep water in large areas of the Baltic and oxygen concentrations below 2 ml/l were generally found at depths exceeding 60 to 80 metres in the whole Baltic Proper. In the whole Baltic proper there was a considerable …

Nutrient conditions were normal for the season. Hydrogen sulphide was found in the deep water in large areas of the Baltic and oxygen concentrations below 2 ml/l was generally found at depths exceeding 60 to 70 metres in the whole Baltic Proper. In the Skagerrak there was an ongoing bloom of a …

The surface water temperatures were normal for the whole area. The nutrient concentrations were low in all sea areas with exception of HS5 at the Jutland coast (high nitrate) and W Landskrona in the Sound (high silicate). These low values are normal for the season due to the algal blooms. Oxygen …

Surface water temperatures as well as all nutrient concentrations were normal for the season in all areas. In the Skagerrak and in the Kattegat, the spring bloom was over. An ongoing spring bloom was observed in the northwestern part of the Baltic. Oxygen concentrations below 2 ml/l were found …

Surface water temperatures were normal for the season in all areas. In the Skagerrak, high nitrate concentrations were detected along the Jutland coast, where there also was a high algal production. In the rest of the Skagerrak and in the Kattegat, the spring bloom was almost over. In the Baltic …

The weather was calm with weak southerly winds. It was mainly sunny weather with temporary fog. The surface nutrient concentrations were still at winter level in the Baltic with the exception of the Bornholm and Arkona basins. The spring bloom had started as was seen from the nitrate and …
