The surface water temperatures were normal for the season in all investigated areas. All nutrients in the surface layer in the southern Baltic Proper were lower than normal. The oxygen concentrations at the bottom in the Sound and in the eastern Kattegat were higher than normal, but lower than 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

Surface water temperatures were normal in the whole area. Salinity in the surface water were normal in the main part of the area, except for the Eastern Gotland Basin were it was below normal. Surface nutrient concentrations in the whole investigated area were normal for the season. Oxygen Last updated: Apr 23, 2014

season in all areas with the exception of some lower silicate concentrations in the western Gotland Basin. Hydrogen sulphide was present at depths from 125 metres in the eastern Gotland Basin, from 90 metres in the western Gotland Basin, at Christiansö and in the Hanö Bight from 80 and 70 metres Last updated: Apr 23, 2014

Surface water temperatures were normal in the whole investigated area. Salinity in the surface layer of the Eastern Gotland Basin was clearly below normal. Surface nutrient concentrations were normal for the season. Oxygen concentrations below 2 ml/l were present at depths exceeding 60-80 metres Last updated: Apr 23, 2014

in Bornholm Basin, 125m in the Eastern Gotland Basin and 80m in theWestern Gotland Basin. The nutrient concentrations in the surface layer were normal for the season in all areas (more or less depleted). Silicate does not deplete in the Baltic Proper but the trend of concentrations lower than normal Last updated: Apr 23, 2014

report have been subject to preliminary quality control procedures only. Due to problems with the CTD-sond, salinity values are uncertain. 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 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 two minor inflows through the Sound in the beginning of late October and November, 20 and 40 km3 respectively, have reached the Gotland Deep and the bottom water in the Baltic is Last updated: Apr 23, 2014
