The year 2006 was characterized by the stagnation period which started in 2005. However, two baroclinic inflow events caused a certain improvement of the oxygen conditions in the Bornholm Basin esp. in the first half of the year. In the eastern Gotland Basin, the whole water column between 140 m depth and the bottom was free of oxygen. The annual mean for the 200 m level decreased from 0.80 ml/l (2004) over -0.23 ml/l (2005) to -1.58 ml/l in 2006. Also in the northern and western Gotland Basin, the stagnation was intensified (NAUSCH et al., 2007).
