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 Last updated: Apr 23, 2014

Skagerrak The surface temperatures varied between 10-14 oC. The nutrient concentrations above the halocline showed low but, for the season, normal values. A strong bloom of Emiliania Huxleyi was observed in the area. Kattegat and the Sound The surface temperatures varied between 12-13 oC in the Last updated: Apr 23, 2014

Surface temperatures in the Skagerrak and Kattegat were higher than normal while the temperatures in the Baltic were normal. Unusually high phosphate concentrations were measured at some stations in the Baltic. The other nutrients showed, for the season, normal values. Oxygen concentrations below 2 Last updated: Apr 23, 2014

The temperature as well as nutrient conditions in the surface layer were mostly normal for the season in all areas. The positive effect of the earlier inflows through the Sound was not any longer to be seen in the eastern Gotland Basin. The concentration of hydrogen sulphide was high.

Nutrient concentrations were normal for the season in all areas. An ongoing bloom preliminary of Aphanizomenon "baltica" and Nodularia spumigena was seen at stations in the Gotland Basins. In the deepwater of the Bornholm Basin, the Hanö Bight, southeast of Baltic Proper and east of Gotland the Last updated: Apr 23, 2014

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 at Last updated: Apr 23, 2014

All nutrients showed for the season normal surface koncentrations, with the exception of phosphate that in the western Gotland Basin were clearly above normal. Oxygen concentrations below 2 ml/l were found in the whole Baltic Proper at depths exceeding 70 to 80 metres. Hydrogen sulphide was found Last updated: Apr 23, 2014

Phosphate concentrations in the Baltic Proper remain much higher than normal for the season. Silicate measurements also showed high levels, while nitrate levels were normal. Nutrient concentrations in the Skagerrak, Kattegat and Sound were normal. In the Baltic Proper oxygen concentrations below 2 Last updated: Apr 23, 2014

Skagerrak The surface temperatures varied between 5.5 and 5.9 oC. The nutrients concentrations above the halocline showed, for the season, normal values. Kattegat and the Sound The surface salinity was higher than normal.The pycnocline started between 4 and 15 metres depth and was weakly developed Last updated: Apr 23, 2014
