This project aims to unearth the characteristics and controls of Antarctic ice sheet loss on timescales of 100s to 1000s of years. The polar ice sheets are getting smaller at an accelerating rate in response to a warming climate, but modern observations are not yet sufficient to determine whether current ice sheet loss marks the start of irreversible retreat. Through a combination of novel geological approaches and numerical ice-flow modelling, this project expects to generate new knowledge on the rates and magnitudes of ice sheet loss, and the processes that will dictate the amount of ice loss in this century and beyond. This work should be beneficial for managing the societal, economic and environmental impacts of future sea-level rise.

该项目的目的是发掘100至1000年的时间尺度上南极冰盖损失的特征和控制。响应温暖的气候，极地冰盖的速度越来越小，但是现代观察尚不足以确定当前的冰盖损失是否标志着不可逆的静修的开始。通过新颖的地质方法和数值冰流建模的结合，该项目预计会产生有关冰盖损失的速度和大小的新知识，以及将决定本世纪及以后的冰损失量的过程。这项工作应该有益于管理未来海平面上升的社会，经济和环境影响。
