Eutrophication and oxygen depletion are well-known threats to the ecological balance of the Baltic Sea, which is increasingly under pressure due to climate change. In this context, large saltwater inflows from the North Sea play a crucial role. They transport oxygen-rich water into the deeper layers of the Baltic Sea, counteracting oxygen deficiency and so-called dead zones.
In a recent study, researchers from Kiel University have now demonstrated for the first time that there are two different types of major saltwater inflows into the Baltic Sea. They arise due to different weather conditions and current patterns. These factors determine the composition of the respective inflows and affect the distribution of salinity and oxygen levels in the Baltic Sea in different ways
