Future Prospects for Improving Knowledge of the History of the Antarctic Ice Sheet

The activities described above indicate continuing gains in significant new knowledge and a more broadly consistent understanding of Antarctic ice-sheet history through improved dating resolution, more careful field observations on land and more advanced geochemical techniques and drilling technology offshore. Understanding present-day ice-sheet behaviour is rapidly advancing through modelling studies integrated with ground truth for surface velocities and mass balance from remote sensing, ice core climatology data from ITASE (2007) and ongoing climate monitoring (AGCS, 2008). However, high-resolution data on geological time scales are still needed from key sectors of the Antarctic Ice Sheet to understand its past behaviour as a basis for credible projections for the future.
