About the Project

The West Antarctic ice sheet contains enough ice to raise global sea levels by several metres and is considered particularly vulnerable to changing climatic conditions. Most of its ice is discharged through a few fast-flowing ice streams (moving at speeds of hundreds of meters per year), which channelize the ice flow from the interior of the ice sheet to its edges. Observations show that ice streams can accelerate and decelerate, widen, narrow, and meander on timescales of hundreds of years or less, thereby significantly affecting the rate of mass loss from the ice sheet.  

Models explaining these changes in flow on the basis of thermal or hydrological feedbacks have recently been developed, but the interplay between these different processes and external climate forcing is still poorly understood. However, these interactions are likely crucial for explaining the dynamic history of the West Antarctic ice sheet and for predicting its future contribution to sea level rise.

The goal of this project is to adapt a numerical ice sheet model to investigate the interplay between these dynamics and their role in ice sheet deglaciation. Simplified mathematical models will be developed to aid in the interpretation of the results and to build a conceptual understanding of leading order processes.

The successful student will expand his/her knowledge in glaciology, fluid dynamics and thermodynamics, and will learn to formulate mathematical models of physical processes. They will learn to solve the differential equations describing these models with a variety of numerical and analytical methods.

An undergraduate degree in geophysics, physics, mathematics, computer science or a related field is desirable, as is knowledge and/or interest in fluid dynamics and numerical solution of partial differential equations.

The Principal Supervisor for this project is Dr Marianne Haseloff.
