In the deep water of the Bornholm Basin, baroclinic inflows were recorded repeatedly during the last years which influenced the oxygen situation positively with oxic conditions throughout 2011. In the deep water of the eastern Gotland Basin, temperature and salinity decreased further and showed extremely low standard deviations illustrating the exceptional low inflow activity. The H2S containing layer has a thickness of around 100 m with a mean H2S content of -3.98 ml/l at 200 m water depth (NAUSCH et al., 2012).
