Cruise report from KBV001 Poseidon

Most parameters showed values typical for the season, except phosphate and silicate that showed elevated concentrations in some parts of the Baltic Proper. Oxygen concentrations below 2 ml/l were observed at depths exceeding 50 to 80 metres in the main part of the Baltic Proper and from 125 …

Cruise report from R/V DANA week 38-42, 2011

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 38-42. The oxygen situation in the Baltic Proper is severe. Low oxygen concentrations (<2 ml/l) were found at depths exceeding 50 to 80 metres in all basins. Hydrogen sulphide was also found in all areas deeper than 70 to 90 metres. For a more detailed description of the oxygen status in the Baltic, see: Report Oceanography No. 42 Areal Extent and Volume of Anoxia and Hypoxia in the Baltic Sea, 1960-2011.
