Project Description

The Antarctic Ice Sheet is one of the largest contributors to global sea level change and its contribution may increase sharply in the near future. It is therefore of considerable importance to quantify ongoing changes, to understand how these changes are driven by external factors, and to improve predictions of the future impacts on sea level.

The catastrophic collapse of several ice shelves in Antarctica between 1995 and 2002 has been a pivotal moment in the ice sheet’s contemporary history. Most recently, the Larsen B Ice Shelf disintegrated over the course of a few weeks in 2002, turning 3500 km2 of previously ice-covered waters into open ocean. This event highlighted the potential for sudden and rapid change, and the subsequent speed-up of the tributary glaciers demonstrated the importance of ice shelves for the stability of the entire ice sheet. To date, however, only limited numerical modelling work has been conducted on the impact of collapsing ice shelves on glacier dynamics, and it still remains to be demonstrated that numerical ice-sheet models can correctly describe the ensuing changes to continental glacier flow.

In this project you will work with a world-leading group of ice modellers at Northumbria University to advance our understanding of these important processes, and to test and improve the predictive skill of ice flow models. You will have access to a unique 30-year record of remote sensing data from the Larsen B area, covering the time periods both before and after the ice shelf collapse. Using state-of-the art numerical flow models, you will make projections for the impact of the collapse on sea level, and model results will be verified against data. Your contribution will be relevant for Antarctica-wide changes, guide future model improvements, and will help refine our understanding of future sea level evolution.

If you have strong numerical skills and a good background in physics, environmental sciences and programming, this project is well suited for you. An undergraduate or MSc degree in physics, mathematics or environmental sciences is essential. Please contact for further information.

Eligibility and How to Apply:

Please note eligibility requirement:
