Expeditionsrapporter från utsjöövervakningen

The weather was windy, from 3 m/s to 22 m/s. The surface water temperatures were between 3 and 4.5°C in the Baltic proper, 2.5 and 4.5°C i the Sound and the Kattegatt. Oxygen concentrations below 2 ml/l were found at 140 m and deeper in both the eastern and the western Gotland basins.

The weather was windy, from 4 m/s to 34 m/s. The surface water temperatures were between 2.1 and 4.8°C in the Gulf of Bothnia, 4.7 and 6.8°C in the Baltic proper, 5.0 and 5.9°C i the Sound and the Kattegatt, and 4.4 and 8.4 in the Skagerrak. Oxygen concentrations below 2ml/l were found at 125 m …

Surface temperatures varied between 8 and 11 degrees C. Nutrient concentrations in the surface water were below normal for the season.

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°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 than …

Oxygen concentrations in the Kattegatt bottom water were mapped. 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.

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 eastern Gotland Basin and in the southeastern Baltic. Hydrogen …

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 HS 5 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 …
