The research proposed here focuses on quantifying the relationship between climate, ice dynamics and glacial sediment production across a range of temporal scales and climate regimes. These topics will be investigated using a combination of theoretical models and empirical field observations. Specific projects and locations include (1) exploring the influence of regional surface and ocean warming on the ice dynamics of polar outlet glaciers in Greenland and the Canadian Arctic (2) quantifying current changes in ice fluxes and sediment fluxes from temperate advancing and retreating glaciers in Patagonia and BC, and (3) exploring the signatures of glacial, fluvial and tectonic influences on the evolution of topography in the Pacific Northwest.

这里提出的研究重点是在一系列时间尺度和气候制度下量化气候、冰动力学和冰川沉积物产生之间的关系。这些主题将使用理论模型和经验现场观测相结合的方法进行研究。具体项目和地点包括(1)探索区域地表和海洋变暖对格陵兰和加拿大北极极地出口冰川冰动力学的影响(2)量化巴塔哥尼亚和不列颠哥伦比亚省温带进退冰川的冰流和沉积物通量的变化，以及(3)探索冰川、河流和构造对太平洋西北地区地形演变的影响特征。
