2001 was characterized by low inflow activity. Only in Oct./Nov. a stronger inflow event occurred (FEISTEL et al., 2003a) causing a rapid increase of the O2 content in the deep water of the Bornholm Basin up to 4.68 ml/l in December. The stagnation lasting since 1995 continued in all deep basins of the central Baltic Sea. In the eastern Gotland Basin, the anoxic water covered the layer between 125 m and the bottom whereby the H2S concentrations near the bottom layer were comparable to that measured at the end of the long lasting stagnation period in 1992 (NAUSCH et al., 2002).
