Description:
In the deep water of the southwestern part of Kiel Bay (Boknis Eck) the oxygen conditions have deteriorated significantly since the 1950s. Comparing data from Boknis Eck and Lightship Fehmarnbelt reveals that each distinct influx of salt-rich deep water from the Kattegat into the Baltic can be detected in the southwestern part of Kiel Bay a few weeks after it is observed in the Fehmarnbelt. Therefore, the frequency of deep water exchange seems to be about the same everywhere in the deeper parts of Kiel Bay. However, in summer, the oxygen content of the inflowing deep water is often very low when it reaches the northeastern part of Kiel Bay. For example, it was less than 40 % saturated in July 1984. This seems to contribute considerably to the general deterioration of oxygen conditions in this region
