Surface water temperatures were below normal in the central Skagerrak and in the Kattegat and Baltic Proper. Surface nutrient concentrations were low in the Skagerrak and Kattegat. Otherwise surface nutrients were normal in most areas with the exception of phosphate concentrations, which were above normal in the Arkona- and Bornholm Basins. Oxygen concentrations below 2 ml/l were found at depths exceeding 60-90 metres in the Baltic Proper, except in the Bornholm Basin. Hydrogen sulphide was found in the eastern and western Gotland Basins.
