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，南极海冰范围一直在急剧下降，这强调了南部大洋和南极环境对全球气候至关重要。该项目旨在通过预测响应大型南部海浪的快速冰撤退来调查海冰损失的关键候选机制。解释波 - 冰反馈的新理论和建模能力将支持预测，并利用最近的研究突破，包括源自卫星和现场观测的新型数据集。预计由于海浪首次量化海冰的结果，在气候研究中对耦合波 - 冰模型的可能产生了重大影响。
