Surface temperatures in the Skagerrak, the Kattegat and in the Baltic were normal. The nutrients showed, for the season, mostly normal values. The salinity of the surface water in the Skagerrak and the Kattegat was now normal. Oxygen concentrations below 2 ml/l were found at depths greater than …

Surface temperatures in the Skagerrak, the Kattegat and in the Baltic except the southern Baltic were higher than normal. The nutrients showed, for the season, mostly normal values. Oxygen concentrations below 2 ml/l were found at depths greater than 80 metres in the whole Baltic Proper. …

Surface temperatures in the Skagerrak and Kattegat were higher than normal while the temperatures in the Baltic were normal. Unusually high phosphate concentrations were measured at some stations in the Baltic. The other nutrients showed, for the season, normal values. Oxygen concentrations below 2 …

The temperature and nutrient concentrations in the surface layer were normal for the season in most areas. The surface salinity on the West-Coast was 10 to 15 psu lower than normal. High nitrate concentrations were measured in the Arkona Basin, two times normal winter values. The spring bloom of …

The temperature as well as nutrient conditions in the surface layer were mostly normal for the season in all areas. The positive effect of the earlier inflows through the Sound was not any longer to be seen in the eastern Gotland Basin. The concentration of hydrogen sulphide was high. Oxygen …

The hydrographic situation in the bottom waters of the Hanö Bight, the northern part of the Bornholm Basin and the Midsjöbankarna were favourable or sufficient for cod presence. Oxygen concentrations below 2 ml/l were found at depths exceeding ~70m in the Western Gotland Basin and in the western …

The temperature as well as nutrient conditions in the surface layer were normal for the season in all areas with the exception of southeastern Skagerrak, where a watermass with elevated nitrate and silicate concentrations were found. Oxygen concentrations below 2 ml/, were found at depths …

Increased nitrate and silicate concentrations of southern North Sea origin, 20 and 13 μmol/ respectively, were recorded in the Jutland current. In the Kattegatt the spring bloom had just began in patches. The lowest oxygen concentration measured in the bottom water of Skagerrak was 4.91 ml/l at …

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 …

Surface phosphate levels in the southeastern Baltic Proper, East Gotland Basin and Northern Baltic Proper were 1–2 standard deviations above the 1990 – 1999 average. This is possibly related to the re-oxygenation of the deep water the previous winter and spring, and the release of phosphate from …
