Antarctic sea ice extent has been in sharp decline since 2016, which is stressing the fragile Southern Ocean and Antarctic environments so vital to the global climate. This project aims to investigate a crucial candidate mechanism of sea ice loss by predicting rapid ice retreat in response to large Southern Ocean waves. New theory and modelling capabilities that account for wave–ice feedbacks will underpin the predictions, leveraging on recent research breakthroughs, including novel datasets derived from satellite and field observations. The outcomes are expected to quantify sea ice retreat due to ocean waves for the first time, with potentially major implications for coupled wave–sea ice modelling in climate studies.

自2016年以来，南极海冰面积一直在急剧下降，这给脆弱的南大洋和南极环境带来了压力，这些环境对全球气候至关重要。该项目旨在通过预测海冰在南大洋巨浪中的快速消退来研究海冰消融的一个关键候选机制。考虑到海浪冰反馈的新理论和建模能力将支持预测，利用最近的研究突破，包括从卫星和现场观测得出的新数据集。预计这一结果将首次量化海浪造成的海冰退缩，并可能对气候研究中的海浪-海冰耦合模型产生重大影响。
