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 …

The bottom water oxygen concentrations in Kattegat Proper were not alarming low. In the Belt Sea concentrations below 2 ml/l were recorded at two stations, Fehmarn Belt and Mecklenburger Bucht. No surface accumulations of cyanobacteria were observed. Due to the ongoing inflow oxygen concentrations …

Nutrient concentrations in the surface waters were normal for the season almost everywhere, with the exception of phosphate, that in the south-eastern Baltic showed clearly enhanced values, and silicate that in the eastern and western Gotland Basins also showed values above normal. A …

Nutrient concentrations in the surface waters were normal for the season almost everywhere. The exception was phosphate which, south-east of Öland, was clearly above normal. Oxygen concentrations below 2 ml/l were found in the whole Baltic Proper at depths exceeding 70 metres. Hydrogen sulphide …

Nutrient concentrations were normal or near normal for the season in most areas. High values of phosphate and silicate were found in the west Gotland basin. The bottom waters in the Baltic Sea, from 70-80 metres had an oxygen concentration of less than 2 ml/l. Hydrogen sulphide was present in the …
