Surface water temperatures were normal, except for in the southern and eastern Baltic, where the temperature was higher than normal. In the Arkona and Bornholm Basins, phosphate- and silicate concentrations in the surface water remained high. The surface water streaming out of the Baltic led to …

In the Skagerrak, 9 stations with complete hydrography were taken. In the Kattegat mapping of oxygen conditions in bottom water was performed, 8 stations with complete hydrography and 12 with oxygen and salinity near bottom were sampled. The lowest oxygen concentration measured in the bottom …

Surface water temperatures were normal for the season in all areas. Phosphate and silicate concentrations were still enhanced in the Arkona and Bornholm Basins. Oxygen concentrations below 2 ml/l were observed in the bottom water of the Arkona Basin and at depths exceeding 70 to 80 metres in the …

Nutrient concentrations in the Skagerrak and Kattegatt were normal. Phosphate concentrations in the surface water of the Arkona and Bornholm Basins remain higher than normal. Oxygen concentrations below 2 ml/l were found at depths exceeding 70 – 80 metres in the entire Baltic proper. Hydrogen …

Surface temperatures were above normal in the whole area. Large amounts of blue-green algae were observed in the eastern and western Gotland Basins and north of Gotland. In the Arkona and Bornholm Basins surface phosphate and silicate concentrations were still high. In the southern Kattegat and the …

An early blue-green algal bloom of Aphanizomenom baltica and Nodularia spumigena was found near the northern and northwest coast of Gotland. Phosphate concentrations in the south and western Baltic Proper remain much higher than normal. Silicate measurements also showed high levels, while nitrate …

Phosphate concentrations in the south and western Baltic Proper remain much higher than normal. Silicate measurements also showed high levels, while nitrate levels were normal. Nutrient concentrations in the Skagerrak and Kattegat were normal. In the Baltic Proper oxygen concentrations below 2 …

Phosphate concentrations in the Baltic Proper remain much higher than normal for the season. Silicate measurements also showed high levels, while nitrate levels were normal. Nutrient concentrations in the Skagerrak, Kattegat and Sound were normal. In the Baltic Proper oxygen concentrations below …

Phosphate concentrations in the Baltic Proper remain much higher than normal for the season. Silicate measurements also showed high levels there, while nitrate levels were normal. Nutrient concentrations in the Skagerrak, Kattegat and Sound were normal. In the Baltic Proper oxygen concentrations …

Hydrographic conditions in the greater part of the Hanö Bight, the Northern Bornholm Basin , around the Midsjö Banks and east of Öland were favourable for cod and no oxygen concentrations below 2 ml/l were recorded. Below 70 to 95 metres depth, both west and east of Gotland, oxygen concentrations …
