Sammanfattning

Surface temperatures were 3 to 5 oC higher than normal in all areas. All nutrients showed, for the season, normal values, with the exception of silicate that showed enhanced concentrations in the eastern Skagerrak and the northern Kattegat. Oxygen concentrations below 2 ml/l were detected in the bottom water in the southern Kattegat and at depths greater than 10 metres at W Landskrona in the Sound. Oxygen concentrations below 2 ml/l were found at depths greater than 70 to 80 metres in the whole Baltic Proper, in the Arkona Basin from 30-40 meters. Hydrogen sulphide was present at depths greater than 125 metres in the eastern Gotland Basin and at the Norrköping Deep, from 100 metres at the Karlsö Deep and from 80 metres in the Bornholm Basin and in the Hanö Bight.
