Timing and Rates of Ice Sheet Thinning in the Ellsworth Mountains, Weddell Sea Embayment: Constraints on West Antarctic Ice Sheet Dynamics

The overall aim is to establish the timing and rate of thinning of the West Antarctic Ice Sheet (WAIS) from its maximum extent in an area inland of the Weddell Sea embayment. The specific objectives are (a) to date geomorphological evidence of ice sheet thinning in the Ellsworth Mountains using in situ cosmomogenic nuclides and (b) to infer WAIS dynamics (specifically grounding line and ice volume changes) in the Weddell Sea embayment through high-resolution glaciological modelling, constrained against the geomorphological record of elevation change through time. The importance of the project is that the past dynamics of the WAIS have implications for its future behaviour, and thus global sea level change.

Statement

To achieve our aim we will have a terrestrial field campaign in the Ellsworth Mountains in season 2005-06, mapping geomorphology and sampling bedrock, erratics and tills for subsequent cosmogenic isotope analysis. Exposure ages on these samples will allow us to determine the vertical thinning history of the WAIS across the mountain range. We will use a high-resolution glaciological model to tie this thinning history to a grounding line history for the WAIS in the Weddell Sea embayment.
