Scientists from the British Antarctic Survey have used hot-water drilling and autonomous underwater vehicles to observe ocean conditions beneath ice shelves. Recent advances in theoretical and computer modelling have used these observations to develop our understanding of the ocean processes controlling ice melting. The aim of this studentship is to improve the representation of this melting in climate models, in order to improve projections of sea level rise. Even on the fastest supercomputers, climate models cannot be run at a resolution high enough to resolve all of the ocean processes controlling melting. Melting must instead be included in the models using simplified representations of the underlying physical processes. The student will test and improve these representations in a state-of-the-art ocean model.

英国南极调查局的科学家们使用热水钻井和自动水下航行器来观察冰架下的海洋状况。理论和计算机模拟的最新进展利用这些观测结果来发展我们对控制冰融化的海洋过程的理解。该奖学金的目的是改善气候模型中这种融化的代表性，以改善对海平面上升的预测。即使在最快的超级计算机上，气候模型也无法以足够高的分辨率运行，以解决所有控制融化的海洋过程。融化必须包括在模型中，使用简化的基本物理过程的表示。学生将在最先进的海洋模型中测试和改进这些表示。
