The project is designed to contribute to answering important questions in climate change: Which polar ice sheets are the most vulnerable to warming? How fast will sea levels rise? What will be the impact on global coasts during the 21st century? The response of polar ice sheets to modest increases in global temperature and the rate of future sea-level rise remains highly uncertain. The project plans to examine the retreat of the polar ice sheets during the last warm interglacial period and the sea-level record archived in the Australian coastal sediments and morphology. It plans to use this unique sea-level signal to fingerprint the ice sheets that contributed the excess meltwater to the oceans and to map the configuration of the southern Australian coast under higher sea levels than present.

该项目旨在回答气候变化中的重要问题：哪些极地冰盖最容易受到变暖的影响？海平面上升的速度有多快？在21世纪世纪，全球海岸将受到什么影响？极地冰盖对全球气温温和上升的反应和未来海平面上升的速度仍然非常不确定。该项目计划研究最后一次温暖的间冰期期间极地冰盖的退缩以及澳大利亚沿海沉积物和形态中存档的海平面记录。它计划利用这一独特的海平面信号来识别为海洋提供过量融水的冰盖，并绘制澳大利亚南部海岸在海平面高于目前的情况下的配置。
