Description

Volcanoes on Ice: Mantle Influence on Antarctic Ice Sheet Evolution. This project will constrain Antarctic mantle dynamics over the past 40 million years using a data-driven computational approach that integrates its volcanic record with complementary geoscientific observations. A major outcome will be the first Antarctic-wide reconstructions of topography and heat flow – surface manifestations of mantle convection that control ice-sheet behaviour. These will be used to explore why the Antarctic Ice Sheet (AIS) formed and how it has since evolved. Benefits include a transformational understanding of connections between the Antarctic surface and its deep interior, reducing uncertainties in forecasting the AIS’ response to climate change, and cementing Australia’s leadership in cutting-edge Antarctic science..
