Over past decades, the Southern Ocean has substantially slowed global surface warming [...] which are central to ocean circulation, carbon and heat fluxes. … Find out more Low-salinity water in the Southern Ocean kept CO₂ locked… Low-salinity water in the Southern Ocean kept CO₂ locked away for [...] Postdoc My aim is to better understand the ocean carbon sink and its changes, with a special focus on the Southern Ocean. I study how the physics of the ocean impact the return pathways of CO 2 to the surface

These transformations not only reshape Arctic ecosystems [...] freshwater, sediments, carbon, nutrients, and contaminants from land to ocean. These changes directly affect the Arctic ocean’s freshwater balance and circulation, sea-ice, marine food webs, greenhouse-gas
