Strong saltwater inflow into the Baltic Sea detected

A large influx of saltwater into the south-western Baltic Sea is currently being detected. The autonomous measuring station operated by the IOW at the Darss Sill has been measuring a strong inflow of salty water throughout the water column since 20.12.2023, which is a comparatively rare occurrence. Over Christmas day, it will become clear whether the inflow is similar in scale to the major saltwater intrusion in 2014. Saltwater inflows are accompanied by oxygen-rich water that could aerate oxygen-poor, deeper basins in the Baltic Sea, which in turn prevents the formation of toxic hydrogen sulphide.
