Relatively few cells were found at all stations which is normal for the season. A quite diverse community but with few cells of each species was however found in the Skagerrak area. The diatom genus Pseudo-nitzschia was found in high abundance at the outer station in Skagerrak (Å17) and at both …

Surface water temperatures, from the Skagerrak to Gulf of Bothnia, were lower than normal. Above normal phosphate and silicate concentrations were recorded in the surface waters of the Western Gotland Basin, in the Bornholm Basin and in the Gulf of Bothnia. Oxygen concentrations below 2 ml/l were …

The oxygen situation in the deep water of the Baltic Proper continues to be serious. The bad conditions measured during the beginning of the 2100-century continues.

The oxygen situation in the deep water of the Baltic Proper continues to be serious. About one sixth (~17%) of the bottom area in the Baltic Proper are affected by anoxia (oxygen free, with toxic hydrogen sulphide present) corresponding to ~10% of the water volume. Acute oxygen deficiency, with …

The Arctic summer sea ice extent is decreasing since the start of satellte observations 1979. On top of that, long-term trend variability exists, including record low extents followed by partial recovery. The latest example is the 2007 rapid ice loss event.

The major differences between the Skagerrak and Kattegat areas during the latest cruise were the high cell numbers of the diatoms Pseudosolenia calcar-avis and Pseudo-nitzschia spp. in the Kattegat phytoplankton samples. The species’ were present in the Skagerrak as well but in low cell numbers. …

Surface water temperatures were normal in the whole area and nutrient levels were also normal expect from silicate which was lower than normal in parts of the Baltic Proper and in the Kattegat. Oxygen levels in the deep water of the Arkona Basin and Hanö Bight were good. In the Bornholm Basin the …
