Glaciers in the Amundsen Sea are rapidly thinning and retreating as a result of ocean-induced changes in ice-shelf buttressing. Projecting the future behaviour of these glaciers is challenging, in particular due to the complex feedbacks between ice and ocean dynamics. To better represent these processes, we explore results from an asynchronous coupling between a high resolution regional configuration of the 3D ocean model MITgcm, and a state-of-the-art ice flow model Úa. In particular, area-wide projections of ice shelf thickness and velocities over the next 150 years are obtained under two limiting scenarios, i.e. sustained warm and cold ocean forcing.
