This project aims to use a high-resolution global modelling approach to understand how Antarctic dense water formation changed in past climates and how to predict future changes. The Southern Ocean is critical in the uptake of heat and carbon from the atmosphere into the deep ocean. The sinking of cold and saline dense water around the coast of Antarctica transports heat and carbon into the deep ocean. Climate models fail to simulate this process and little is known about how dense water formation responds to changes in climate. Identification of critical vulnerabilities associated with Antarctic ice shelf melting and sea level rise will guide Southern Ocean observation systems and Australian climate adaptation programs.

该项目旨在使用高分辨率全球建模方法来了解南极稠密水的形成在过去的气候中如何变化以及如何预测未来的变化。南大洋在吸收大气中的热量和碳进入深海方面至关重要。南极洲海岸周围寒冷和含盐的稠密海水的下沉将热量和碳输送到深海。气候模型无法模拟这一过程，人们对稠密水的形成如何响应气候变化知之甚少。确定与南极冰架融化和海平面上升相关的关键脆弱性将指导南大洋观测系统和澳大利亚气候适应计划。
