This DECRA project aims to significantly reduce the uncertainties in future projections of the Antarctic contribution to global and regional sea-level rise. This will be achieved by including, for the first time, the influence of interactions with the subglacial hydrologic system and surrounding ocean circulation on the ice sheet dynamics, using a coupled ice–ocean–hydrology model. This research will build on Dr Zhao's international expertise in ice sheet modelling and coupled ice–ocean modelling. This project provide substantial benefits to Australia and internationally, particularly in regions vulnerable to rising sea levels, by producing more accurate sea-level rise projections for policy and mitigation strategies.

这一DECRA项目旨在大大减少今后预测南极对全球和区域海平面上升的影响时的不确定性。这将通过使用冰-海洋-水文学耦合模型，首次包括与冰下水文系统和周围海洋环流的相互作用对冰盖动态的影响来实现。这项研究将建立在赵博士在冰盖建模和冰-海耦合建模方面的国际专业知识基础上。该项目通过为政策和缓解战略提供更准确的海平面上升预测，为澳大利亚和国际社会带来了巨大利益，特别是在容易受到海平面上升影响的地区。
