Cruise reports from the marine monitoring

In Skagerrak and Kattegat, surface salinity was much lower than usual, which indicate a strong influence of outflowing Baltic water. The mapping of nutrients in the Kattegat showed small variations and overall normal concentrations. In the Baltic Proper the concentrations of phosphate and silicate …

The surface water temperatures were normal for the season in all investigated areas. All nutrients in the surface layer, except silicate, showed normal concentrations. The oxygen concentrations in the bottom water of the Sound and Kattegat were higher than normal, but lower than normal in the …

Nutrient levels were largely normal in the whole investigated area. In the Baltic Proper, oxygen concentrations below 2 ml/l (hypoxia) were found at depths exceeding 70 to 80 metres, while a total deficiency of oxygen (anoxia) was found below 70 to 125 metres. All parameters in the Gulf of …

The surface water temperatures were normal for the season in all investigated areas. All nutrients in the surface layer in the southern Baltic Proper were lower than normal. The oxygen concentrations at the bottom in the Sound and in the eastern Kattegat were higher than normal, but lower than …

Surface water temperatures were normal in the whole area. Salinity in the surface water were normal in the main part of the area, except for the Eastern Gotland Basin were it was below normal. Surface nutrient concentrations in the whole investigated area were normal for the season. Oxygen …

Skagerrak: The surface temperatures varied between 10-14 oC. The nutrient concentrations above the halocline showed low but, for the season, normal values. A strong bloom of Emiliania Huxleyi was observed in the area. Kattegat and the Sound: The surface temperatures varied between 12-13 oC in …

Surface water temperatures were normal in the whole investigated area. Salinity in the surface layer of the Eastern Gotland Basin was clearly below normal. Surface nutrient concentrations were normal for the season. Oxygen concentrations below 2 ml/l were present at depths exceeding 60-80 …

Surface water temperatures as well as all nutrient concentrations were normal for the season in all areas. In the Skagerrak and in the Kattegat, the spring bloom was over. An ongoing spring bloom was observed in the northwestern part of the Baltic. Oxygen concentrations below 2 ml/l were found …

Surface water temperatures were normal for the season in all investigated areas. All nutrients in the surface layer were low and had increased since the last observation, which is normal for the season. The oxygen conditions in the Kattegat bottom water were relative good. The oxygen condition …

In all regions the surface water temperatures were over the normal. In some regions in the southern Baltic and in the Sound the concentration of phosphate was higher than normal. Also silicate concentrations were elevated, while the nitrogen components showed, for the season, normal values. The …
