On the West Coast as well as in the Arkona Basin, all nutrients were almost depleted. A strong bloom was ongoing in the Hanö Bight and in the Bornholm Basin. In the remaining parts of the Baltic Proper winter conditions prevailed. The deep water in the Arkona and Bornholm Basins as well as in …

The hydrographic situation in the bottom waters of the Hanö Bight, the northern part of the Bornholm Basin and the Midsjöbankarna were favourable for cod presence. The inflow of new water from Kattegat in January has improved the situation considerably. In some bottom areas (>70m) West and South …

Nutrient concentrations were normal for the season in most areas, with the exception of the Eastern and Northern Gotland Basins where phosphate and silicate showed elevated levels. After the latest inflow to the Baltic in January, the deep waters of the Arkona Basin, Bornholm Basin and the major …

Nutrient conditions in the surface layer were mostly normal for the season, in all areas. Surface temperature was slightly below normal. Oxygen concentrations below 2 ml/l, were found at depths exceeding 70 to 80 metres in the Bornholm Basin and in the western, eastern and northern Gotland …

The surface water nutrient concentrations were normal in almost all areas, with the exception of the phosphate and silicate concentrations, which were higher than normal in the Baltic Proper. Oxygen concentrations below 2 ml/l were found in the Baltic Proper at depths exceeding 60 to 80 metres. …

The bottom water oxygen conditions in the Kattegat were good, > 4.5 ml/l. At W Landskrona in the Sound, oxygen concentration in the bottom water was 2.58 ml/l. In the Baltic Proper oxygen concentrations below 2 ml/l were found at depths exceeding 60 to 70 metres. Hydrogen sulphide was found in the …

On the Öland side of the West Gotland Basin oxygen conditions at the bottom were good. The lowest recorded concentration was 3.1 ml/l at a depth of 66 meters. The lowest recorded concentration in the Bordholm Basin was 1.0 ml/l at a depth of 60 meters. Other 10 stations in the Hanö Bight had oxygen …

The bottom water oxygen concentrations in Kattegat Proper were not alarming low. The oxygen concentration at W Landskrona was from 25 metres and deeper 2.25 ml/l, corresponding to 38 % saturation. In the Baltic oxygen concentrations below 2 ml/l were found at depths exceeding 60 to 80 metres. …

In the central Kattegat, oxygen concentration near the seabed was not particularly low. An oxygen concentration below 2 ml/l was measured in Skälderviken however. In the Baltic Proper, oxygen concentrations below 2 ml/l were found at depths exceeding 60 to 70 metres. Hydrogen sulphide was found …

In the Skagerrak 11 stations with complete hydrography were taken. In the Kattegatt mapping of oxygen conditions in bottom water was performed, 12 stations with complete hydrography and 11 with oxygen and salinity near bottom were sampled. The lowest oxygen concentration measured in the bottom …
