My research aims to improve representation of key physics in ice sheet simulations. Such simulations are increasingly used to assess possible rates of future sea level rise under climate change, and better constraints on ice sheet behaviour were identified as a key goal in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). In particular, I will address the dynamics of subglacial melt water drainage and its effect on ice flow speeds. This has been observed as a key process in both, Antarctica and Greenland, but there are currently only crude models available. My research will aim to incorporate current understanding into improved models, to constrain these models using field observations, and explore their implications for glacier and ice sheet behaviour as well as water discharge from these ice masses.

我的研究旨在改善冰盖模拟中关键物理的表征。此类模拟越来越多地用于评估气候变化下未来海平面上升的可能性，政府间气候变化专门委员会（IPCC）第四次评估报告将更好地限制冰盖行为确定为关键目标。我将特别讨论冰下融水排水的动态及其对冰流速度的影响。这在南极洲和格陵兰岛都被视为一个关键过程，但目前只有粗略的模型可用。我的研究旨在将当前的理解纳入改进的模型中，使用现场观测来约束这些模型，并探索它们对冰川和冰盖行为以及这些冰块的水排放的影响。
