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，南极海冰范围急剧下降，这给脆弱的南大洋和南极环境带来了压力，该环境对全球气候至关重要。该项目旨在通过预测大规模海冰消退而研究海冰消失的重要候选机制。南大洋波浪。利用最近的研究突破，包括来自卫星和实地观测的新数据集，解释波冰反馈的新理论和建模能力将支撑预测。预计结果将量化海冰退缩。首次对海浪进行研究，对气候研究中的耦合波-海冰建模具有潜在的重大影响。
