"Rates of Melting of the Large East Antarctic Ice Sheet under near Future Environmental Conditions"

The East Antarctic Ice Sheet (EAIS) has an ice volume equivalent to 52m of global sea level rise. Understanding the response of this vast ice sheet to warmer temperatures is critical given anthropogenic climate warming predicted for the near future. In particular, low-lying, marine based areas such as the Wilkes Subglacial Basin, may be vulnerable to periods of climatic warmth. The Pliocene (~2.6 to 5.3 million years ago) is a suitable analogy for future conditions as global temperatures were similar to those predicted for the end of this century. Global mean sea level estimates for this epoch are substantially higher than present and imply a contribution from the EAIS. Previous work has shown that the ice sheet margin at Wilkes Subglacial Basin, retreated by several hundred kilometres in response to warmer periods during the Pliocene. I will be analysing the geochemical composition of detrital material deposited offshore to identify the likely location the ice margin and how rapidly it varied.
