About us

We investigate the role of the deep ocean in the climate system, from its present and future stratification in climate models to its interactions with the cryosphere and atmosphere in in-situ and remote observations. We increasingly use deep learning to do so, to downscale the models, detect patterns in the sea ice, or find the drivers of observed variability.
