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 in 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 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 found in the Eastern, Western and Northern Gotland Basins at depths exceeding 70 to 80 metres. Hydrogen sulphide was found from 125 metres in the …

The temperature of the surface water in the Skagerrak was some degree higher than normal. The nutrient concentrations were higher than normal in the Kattegat and the oxygen content of the bottom water was lower. Nutrient conditions and surface water temperatures were normal for the season in the …

Nutrient conditions and surface water temperatures were normal for the season in all areas. Oxygen concentrations below 2 ml/l were found at the bottom in Skälderviken, in the Sound from 15 metres, in western Arkona bassin from 40 meters and in the rest of the Baltic Proper at depths greater than …

Nutrient conditions were normal for the season in all areas. Oxygen concentrations below 2 ml/l were found in the whole Baltic Proper at depths greater than 70 to 80 metres. Hydrogen sulphide was present in the Eastern and Western Gotland Basin at depths greater than 90 metres, in the Bornholm …

The surface water temperatures were higher than normal in all areas (although the temperature had dropped 1.5-2.5°C in the Skagerrak and northern Kattegat since the previous expedition) with the exception of the Western Gotland Basin. The temperature was 17.2-20.2°C in Skagerrak-Kattegat and …

The surface water temperatures were higher than normal in all areas with the exception of the western Gotland Basin. The temperature was between 19 and 20.8°C in the Kattegat – Skagerrak and between 16.4 and 19°C in the Baltic.The nutrient concentrations in the surface layer were normal for the …

Nutrient conditions were normal for the season in all areas. Oxygen concentrations below 2 ml/l were found in the whole Balic Proper at depths greater than 70 metres. Hydrogen sulphide was present in the eastern and western Gotland Basins at depths greater than 125 metres, in the Hanö Bight from 70 …

The temperature was normal, however in the higher region within normal values of the Skagerrak and the Kattegat. Nutrient concentrations in the surface layer were normal for the season in all areas, except the silicate concentration of the Baltic that was slightly lower. Hydrogen sulphide was …

The temperature and nutrient concentrations in the surface layer, were normal for the season in all areas. The spring bloom of phytoplankton had terminated in most of the areas covered. Only in the east part of the Baltic proper it was still going on. Hydrogen sulphide was present at depths greater …
