Title: Mathematical modelling of the Antarctic ice sheet

Abstract: The Antarctic ice sheet is the largest body of ice in the planet and is expected to contribute significantly to future sea-level rise due to climate change. The majority of this sea-level rise is expected to come from Antarctica’s fastest-moving glaciers, known as ice streams. The rapid sliding of these ice streams is controlled by the presence and movement of water at the base of the ice.

To understand the complex dynamics of ice streams and the water beneath, we can employ PDE-based mathematical models. In this talk I will outline an example of such a model for the ice-water system, and discuss the structure and solutions of the resulting PDEs, along with the implications for the Antarctic ice sheet.
