Present-day ice sheets are melting, and the meltwater generated by them is contributing to sea level rise. Numerical ice sheet models are being used to predict future changes, though the linkages between ice sheet hydrology, ice dynamics and climate remain unclear. My research program provides empirical verification data (e.g., past ice sheet margins, meltwater channel type and character) vital for improving these models and their predictions, and for unraveling the history of past ice sheets. Specifically, the research in this application will:

如今的冰原正在融化，它们产生的融水正在导致海平面上升。数值冰盖模式被用来预测未来的变化，尽管冰盖水文、冰动力和气候之间的联系尚不清楚。我的研究项目提供了经验验证数据（例如，过去的冰盖边缘，融水通道类型和特征），这对于改进这些模型及其预测，以及揭示过去冰盖的历史至关重要。具体而言，本应用程序的研究将：
