Abstract:
Reconstructing and predicting the response of the Antarctic Ice Sheet to climate change is one of the major challenges
facing the Earth Science community. There are critical gaps in our knowledge of past changes in ice elevation
and extent in many regions of East Antarctica, including a large area of Dronning Maud Land. An international
Swedish-UK-US-Norwegian-German project MAGIC-DML aims to reconstruct the timing and pattern of ice surface
elevation (thus ice sheet volume) fluctuations since the mid-Pliocene warm period on the Dronning Maud
Land margin of the East Antarctic Ice Sheet. A combination of remotely sensed geomorphological mapping, field
investigations, surface exposure dating and numerical modelling are being used in an iterative manner to produce a
comprehensive reconstruction of the glacial history of Dronning Maud Land. Here we present the results from the
first phase of this project, which involves high-resolution numerical simulations of the past glacial geometries and mapping of the field area using historic and recent aerial imagery together with a range of satellite acquired data.
