The MIO research laboratory is a component of the OSU-Pytheas Institute and is under the joint direction of Aix-Marseille University, Toulon University, the CNRS and the IRD. Our goal is to better understand the oceanic system and its evolution in response to global changes. The MIO constitutes a center of expertise in marine biology, ecology, biodiversity, microbiology, halieutics, physics, chemistry, biogeochemistry and sedimentology. Our working environment is the world ocean, alongside its continental, atmospheric and sediment interfaces. We strive for an ocean environment with a future !
