Ocean Forced Evolution Of The Antarctic Ice Sheet

ACE PROJECT R1.2

OCEAN FORCED EVOLUTION OF THE ANTARCTIC ICE SHEET

The ACE CRC’s Project R1.2 team is working to understand how the Antarctic ice sheet is responding to a warming ocean, to improve projections of future sea level.


The rate at which ice discharges from the Antarctic continent into the oceans is presently the greatest source of uncertainty in forecasts of global sea level rise.  Recent observations suggest that the contribution to sea-level rise from the West Antarctic and the much larger East Antarctic ice sheet is increasing.

Reducing the uncertainty is important since the two great parts of Antarctica hold around 70 per cent of the world’s fresh water and more than 90 per cent of its ice. If the ice sheet melted completely, the global sea level would rise by about 60 meters.

The ACE CRC’s Ocean Forced Evolution of the Antarctic Ice Sheet project is working to provide public and private sector decisionmakers with improved information to guide informed policy decisions on sea level rise mitigation and adaptation.  To achieve this, researchers are working to understand how the Antarctic ice sheet is likely to respond to a warming ocean, and which regions face the greatest risk of increased ice discharge.

The project employs a wide variety of methodologies from field surveys of the Antarctic ice sheet to computer modelling of complex ocean-ice sheet interactions.  The scientific insights gained through this research are helping to improve the accuracy of ice-sheet computer models, and provide more reliable projections of future sea level.
