The warm baroclinic inflow of Nov/Dec. 2009 ventilated the Bornholm Basin. From January to March, O2 concentrations of 2–3 ml/l were measured at 80 m depth. In the eastern Gotland Basin, this warm water mass was detected within the halocline in March, still containing 0.9-1.0 ml/l O2. The deep water was not oxygenated. The annual mean of H2S concentrations of -4.29 ml/l at 200 m depth was higher than the year before (-3.09 ml/l) and higher than the one measured at the end of the last stagnation period in 2002 (NAUSCH et al., 2011).
