In Aug./Sept. 2002, the Darss Sill mast recorded inflowing water (FEISTEL et al., 2003b, 2004) in a thick bottom layer with high salinity and O2 content between 4 and 1 ml/l, which carried exceptionally warm water into the adjacent basins. In Oct./Nov. 2002, an additional small inflow occurred, which added even more warm water and caused a ventilation of the Gdańsk Basin by November. Warm water later propagated further towards the eastern Gotland Basin and improved the stagnation conditions slightly without terminating it (NAUSCH et al., 2003a).
