Melting Antarctic ice sheets are responsible for 28% of global sea level rise in recent decades, and can contribute more than 1 metre of sea level rise by year 2100, and a staggering 15 metres by 2500. Increased glacial melt rates are best understood by studying changes in the circulation of water around the Antarctic coastline. The combination of physical processes that must be resolved in this region places a high demand on ocean observations and modelling systems. This project uses a series of high-resolution ocean and ice experiments, cross-validated with observations, to provide a deeper understanding of how waters at the Antarctic margin respond to both anthropogenic and natural climate forcing.

近几十年来，融化的南极冰盖造成了全球海平面上升的28%，到2100年可能导致海平面上升1米以上，到2500年可能导致海平面上升15米。通过研究南极海岸线周围水循环的变化，可以最好地了解冰川融化率的增加。这一区域必须解决的物理过程的组合对海洋观测和建模系统提出了很高的要求。该项目利用一系列高分辨率海洋和冰实验，并与观测结果进行交叉验证，以更深入地了解南极边缘的沃茨如何对人为和自然气候强迫作出反应。
