Low oxygen concentrations were found in the Laholm Bay 0.16 ml/l, in Skälderviken, 0.64 ml/l and in the Sound, just around 1 ml/l. In the rest of Kattegat, bottom water oxygen concentrations varied between 2 and 4.5 ml/l, highest in the northern part.

Surface temperatures varied between 15.5 and 17.5°C. Nutrient concentrations were normal for the season, nitrite and nitrate below detection limits (0.02 and 0.10 μmol/l repectively). Posphate between 0.02 and 0.3 μmol/l and silicate from 0.3 μmol/l in the Skagerrak to 10 μmol/l in the Baltic. …

The surface temperatures were between 14.3 and 17.7°C. Nutrient concentrations were normal for the season in mainly all areas. In the Skagerrak the surface salinity was <30 psu at the coastal stations and >32 at the western stations of the Å transect . In the Kattegatt the surface salinity ranged between 20 and 21 psu. Oxygen …

The surface temperatures were between 14 and 16°C. Nutrient concentrations were normal for the season in mainly all areas. In the Skagerrak the surface salinity was >30 psu with exception of the easterly station of the Å cross section, where the salinity was 24 psu depending on the transit of the …

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 …

Temperature as well as nutrient conditions in the surface layer were normal for the season in all areas. Oxygen concentrations below 2 ml/l were generally found at depths exceeding 60 to 70 metres in the whole Baltic Proper. Hydrogen sulphide was found in the deep water in the eastern Gotland …
