A relatively intensive baroclinic inflow of April/May caused only minor effects in the Bornholm Basin but could maintain oxic conditions in the depth. In the eastern Gotland Basin, H2S concentrations increased further (-3.09 ml/l) and were in the same range as at the end of the last stagnation period in 2002 (-3.82 ml/l). The same development was observed in the more northerly situated Fårö Deep. The MBI of January 2003 was unable to ventilate effectively the western Gotland Basin and stagnant conditions prevailed (NAUSCH et al., 2010).
