Expeditions

Researchers at GEOMAR are working around the globe to collect information about the state of the ocean. Their data and samples contribute to a more precise understanding of crucial processes from the seafloor to the atmosphere and the ocean’s role in the climate system. This also helps to better assess future changes and develop strategies that tackle climate change, ensure a sustainable use of the ocean, and protect us against marine natural hazards.
