The surface temperature was over normal in Kattegat and the salinity in the surface layer was slightly over normal values in Skagerrak. All nutrients, in the surface layer, showed normal values for the season except for silicate which was below normal in the eastern Gotland Basin. In the Arkona basin the oxygen concentration in the bottom water had decreased and was now just below 3 ml/l. In the Bornholm basin the oxygen values were still around 2 ml/l in the deep water. In the remaining parts oxygen levels below 2 ml/l were found at depth exciding 70-80 meters. High concentrations of hydrogen sulphide were found in the eastern and western Gotland basin from 125 meters depth.
