Summary
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 normal in the central and northern parts. Due to the inflows during the autumn to the Baltic Proper the oxygen situation had improved in the Arkona Basin, the Hanö Bight and the western parts of the Bornholm Basin. In the eastern parts of the Bornholm Basin, low oxygen concentrations, just above 0 ml/l, were still present. Hence, the inflow had not reached this area.
