Cruise report from KBV002 Triton week 14, 2013

Surface water temperatures were somewhat below normal in the whole investigated area. All nutrients showed concentrations typical for the season in the Skagerrak and Kattegat, while they in the Baltic Proper were above normal. The bottom water in the Arkona Basin was well oxygenated. Oxygen …

Cruise report from KBV001 Poseidon week 12, 2013

Surface water temperatures were below normal in all investigated areas. Nutrients in the surface layer were almost completely consumed in the Skagerrak and Kattegat and the spring bloom was in progress. In the Baltic Proper winter conditions still prevailed and nutrient concentrations were above …

Cruise report from KBV001 Poseidon week 9, 2013

In the western Skagerrak the spring bloom was ongoing and in the Kattegat it was in the beginning. The concentrations of phosphate and silicate were over to much over normal levels in the whole area. The bottom water of the Arkona Basin was well oxygenated. Oxygen concentrations below 2 ml/l were …

Cruise report from KBV002 Triton week 7, 2013

Surface water temperatures were normal in the whole area. Surface nutrient concentrations were normal at most of the visited stations. Oxygen concentrations below 2 ml/l were present at depths exceeding 70-90 metres. Hydrogen sulphide was found deeper than 90 metres in the western Gotland Basin and …

Cruise report from KBV001 Poseidon week 51, 2012

A new agreement with the Swedish Coastguard meant that only the Swedish west coast and south western Baltic Proper (Arkona and Bornholm Basins) were sampled. In Skagerrak and Kattegat, nutrient conditions were normal for the season, except in the south of Kattegat and the Sound, were phosphate …

Cruise report from KBV002 Triton week 49-50, 2012

In the investigated parts of the Baltic Proper, concentrations of phosphate were higher than normal, while inorganic nitrogen and silicate showed normal values. Oxygen concentrations below 2 ml/l (hypoxia) were found at depth exceeding 55 to 80 metres, while total lack of oxygen (anoxia) was …

Cruise report from KBV001 Poseidon week 45, 2012

A new agreement with the Swedish Coastguard meant that only the Swedish west coast and south western Baltic Proper (Arkona and Bornholm Basins) were sampled. In addition, due to problems with cranes on board, no CTD-measurements or zooplankton sampling could be carried out. In Skagerrak and …

Cruise report from R/V DANA week 40-42, 2012

The survey was completed in co-operation with SLU (Swedish University of Agricultural Sciences) and within the international acoustic survey in the Bothnian Sea and Baltic Proper (BIAS) during weeks 40-42. The oxygen situation in the Baltic Proper is severe. Low oxygen concentrations (<2 ml/l) were found at depths exceeding 50 to 100 metres in all basins. Hydrogen sulphide was also found deeper than 70 to 90 metres. For a more detailed description of the oxygen status in the Baltic, see: Report Oceanography No.45 Oxygen Survey in the Baltic Sea, 2012. http://www.smhi.se/publikationer
