This project aims to provide new insight into how ice flow processes influence Antarctic ice loss - a serious unsolved problem in predicting how much Antarctica will contribute to sea level rise. Using a state-of-the-art ice sheet model and real-world glaciological observations, this project expects to generate new knowledge of the mechanisms, and environmental and climatic conditions that control ice flow. Expected outcomes of this project are improved estimates of Antarctica’s contribution to future sea level rise. This project should provide substantial benefits in Australia and internationally, particularly in regions vulnerable to rising sea levels, by producing a sound evidence base for policy and mitigation strategies.

该项目旨在为冰流过程如何影响南极冰川流失提供新的见解--这是预测南极洲将在多大程度上导致海平面上升的一个严重悬而未决的问题。利用最先进的冰盖模型和真实世界的冰川观测，该项目有望产生关于控制冰流的机制以及环境和气候条件的新知识。该项目的预期结果是改进了对南极洲对未来海平面上升的贡献的估计。该项目应为政策和缓解战略提供可靠的证据基础，从而在澳大利亚和国际上带来实质性的好处，特别是在易受海平面上升影响的区域。
