The surface temperatures and nutrients concentrations were normal for the season in all areas. Oxygen concentrations below 2 ml/l was generally found at depths exceeding 70 to 90 metres in the whole Baltic Proper. Hydrogen sulphide was found in the deep water at the station BY 4 east of Bornholm …

The surface temperatures were higher than normal, on the west coast up to 5 oC above mean for the season. Nutrient concentrations were normal for the season in all areas. Oxygen concentrations below 2 ml/l was generally found at depths exceeding 80 to 90 metres in the whole Baltic Proper. Hydrogen …

The temperatures varied between 4.6°C in the northern Baltic Sea to 10°C in the Kattegatt. The nutrient concentrations were normal for the season with a few exceptions. An intense alagal bloom was observed in the eastern Baltic Sea and an oxygen saturation of almost 140% was measured. Hydrogen …

The lowest temterature of the surface water was 2.5°C and the highest was 4.7°C. Hydrogen sulphide was found only in the eastern Gotland Basin, from 125 and 130 meters in the Fårö and the Gotland Deep respectively. In the Skagerrak, the Kattegat, the Sound and in the southern Baltic (BY1 and the …
