In the Skagerrak, 10 stations with complete hydrography were taken. In the Kattegat mapping of oxygen conditions in bottom water was performed, 11 stations with complete hydrography and 19 with oxygen and salinity near bottom were sampled. The lowest oxygen concentration measured in the bottom …

High concentrations of phosphate were measured in the southern Baltic Proper. Silicate concentrations were elevated in the northern parts of the Baltic Proper, while concentrations were below normal in the south parts. The nitrogen components showed normal values. Oxygen levels in the deep …

Surface temperatures were normal throughout the area. Nutrient concentrations in the surface layer were normal for the season, except in the Arkona and Bornholm Basins where phosphate and silicate levels were higher than normal. At the Fårö Deep and western Gotland Basin, silicate concentrations …

Surface temperatures were normal or below normal throughout the area. No surface accumulations of cyanobacteria (blue green algae) were observed in the Baltic. Nutrient concentrations in the surface layer were normal for the season, except in the Arkona and Bornholm Basins where phosphate and …

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 …

High concentrations of phosphate were measured in the southern Baltic Proper. Also silicate concentrations were elevated, while the nitrogen components showed, for the season, normal values. The spring bloom in Skagerrak and Kattegat was over, while it was still ongoing in the Baltic. Hydrogen …

Nutrient concentrations in Skagerrak and Kattegat were normal for the season. In the Sound silicate concentrations were enhanced. The other nutrients showed normal values. Inorganic nitrogen (DIN) had been consumed in the coastal waters of Skagerrak and in Kattegat and in all stations in the Baltic …

Surface water temperatures were normal for the season in all investigated areas. All nutrients in the surface layer were at low concentrations, which is normal for the season. The oxygen conditions in the Kattegat bottom water were good, while they were relatively poor in the southern Baltic …

Surface water temperatures were above normal in the whole area. Salinity in the surface water of the Eastern Gotland Basin was clearly below normal. Surface nutrient concentrations were normal at most stations. Oxygen concentrations below 2 ml/l were present at depths exceeding 70-90 metres. …

This report offers results from two August cruises. The phytoplankton diversity was low in the Skagerrak and the Kattegat areas. Merely small species were found in high cell numbers, i.e. the coccolithophorid Emiliania huxleyi, known to colour the ocean turquoise when blooming. The chlorophyll a …
