Central to these changes are the polar regions, oceans, and coastal and shelf seas, which play crucial roles in regulating the Earth's climate and supporting [...] ty and have a critical influence on both regional and global climate by affecting sea-ice cover, ocean circulation, atmospheric conditions and finally coastal areas.

provide answers to big questions on polar and global climate change. Future climate change in the Arctic and Antarctic depends on feedbacks governed by small-scale processes: How do the surface fluxes of [...] momentum and particles change as the atmosphere becomes less stable, and as sea ice gives way to open ocean? How do clouds and precipitation change in response to changes in temperature, moisture, circulation

Over past decades, the Southern Ocean has substantially slowed global surface warming [...] Low-salinity water in the Southern Ocean kept CO₂ locked… Low-salinity water in the Southern Ocean kept CO₂ locked away for decades - New study reveals an overlooked oceanic carbon storage mechanism. Find [...] 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
