The IOW is an independent research institution specializing in interdisciplinary study of coastal oceans and marginal seas. In particular, our work focuses on the Baltic Sea ecosystem. The institute is divided into four sections: physical oceanography, marine chemistry, biological oceanography, and marine geology. Our researchers also teach at the universities of Rostock and Greifswald.
Oxygen minimum zones caused by intense microbial degradation processes of organic matter are a characteristic feature of the Baltic Sea. The hostile living conditions of these so-called ‘dead zones’ become even more pronounced, when toxic hydrogen sulphide is produced by bacterial activity. To visualise the spatial and temporal distribution and dynamics of these areas, IOW now has published in the 100th issue of its journal “Marine Science Reports” a unique collection of over 250 maps covering data of more than four decades.
