GEOMAR: Our World is the Ocean

GEOMAR explores the global ocean from the seafloor to the atmosphere to understand the ocean system and enable the development of sustainable solutions for pressing societal issues. Its research and its commitment to knowledge and technology transfer contribute significantly to preserving the function of the ocean and safeguarding it for future generations.

GEOMAR research covers a unique range of physical, chemical, biological and geological ocean processes. Members of the four research divisions Ocean Circulation and Climate Dynamics, Marine Biogeochemistry, Marine Ecology and Dynamics of the Ocean Floor cooperate in the three core themes Ocean and Climate, Marine Ecosystems and Biogeochemical Cycles and Ocean Threats and Benefits as well as the four Integrative Research Foci Atlantic Ocean Upwelling, Marine Carbon Sinks, Digital Twin Ocean and Metals in the Ocean. All work focuses on the open “blue” ocean.
