Description The research supported by this award has led to two key findings:

- Oceanic mixing in the cavity beneath Pine Island Glacier (one of the fastest-melting glaciers in Antarctica) is enhanced above a submarine ridge, and promotes the transport of heat toward the base of the glacier.

- The meltwater outflow from Pine Island Glacier is subject to a type of dynamical instability that prevents it from ascending to the ocean surface. An idealised model indicates that this instability is likely widespread around Antarctica, with important consequences for how accelerated Antarctic melting will influence the climate system.
Exploitation Route The above findings are likely to lead to significant advances in climate-scale models of ocean - ice sheet interactions.

Description In this award, we have resolved the long-standing question on why meltwater from the Antarctic Ice Sheet settles at depth instead of rising to the ocean surface. This will impact future climate-scale model development for climate and sea level rise projections.
