Our paper on a new ice shelf basal melt parameterisation is out! tc.copernicus.org/articles/19/...
Small-scale processes in the ocean drive ice shelf basal melt, and large-scale ocean models can’t resolve these processes. Therefore, models use melt parameterisations, but these can still be improved.

Stratified suppression of turbulence in an ice shelf basal melt parameterisation
Abstract. Ocean-driven basal melting of Antarctic ice shelves is an important process that affects the Antarctic Ice Sheet, global climate and sea level. Basal melting is controlled by small-scale pro...

From sea ice to ocean currents, Antarctica is now undergoing abrupt changes – and we’ll all feel them
The vast ice of Antarctica has long seemed impregnable. But sudden changes are arriving – from shrinking sea ice to melting ice sheets and slowing ocean currents.
