Main focus was on the lingering effects of the MBI of January 2003 in the deep water of the different basins. During the course of 2004, the oxygen content in the Bornholm and eastern Gotland Basins decreased continuously due to mineralisation processes. In the Gotland Deep, again anoxic conditions have restored below 200 m water depth indicating the beginning of a new stagnation period. In the Landsort Deep, traces of oxygen were found only shortly and the Karlsö Deep remained anoxic throughout the whole year (NAUSCH et al., 2005).
