The Leibniz-Institut für Ostseeforschung Warnemünde (IOW) is a renowned research institution dedicated to interdisciplinary marine research in coastal and marginal seas. The institute focuses on studying the ecosystem of the Baltic Sea, with four sections covering Physical Oceanography, Marine Chemistry, Biological Oceanography, and Marine Geology. IOW conducts cutting-edge research in various key areas, including the study of small- and mesoscale processes, basin-wide ecosystem dynamics, ecosystem changes over time, and the interaction between coastal seas and society.

The institute aims to deepen our understanding of the ecological interface between land and open sea through its new research focus, STB - Shallow Water Processes. Besides its research activities, IOW also offers valuable educational resources for schools, such as free teaching materials on the topic of Plastic in the Sea. Additionally, the institute actively engages with the public through podcasts and provides regular updates on the latest research findings from its partner institutions.

With its commitment to fostering scientific excellence, the IOW is a trusted authority in Ostsee (Baltic Sea) research and a valuable contributor to understanding and mitigating the impacts of climate change
