This two-year award supports collaborative research in polar glaciology between Roger LeB. Hooke of the University of Minnesota and Wibjorn Karlen of the University of Stockholm. The investigators will conduct research on Storglaciaren, a small valley glacier in northern Sweden. Their principal objective is to develop a global model for predicting glacier motion from meteorological data. Dr. Hooke and his team, including an advanced graduate student and postdoctoral researcher, will spend several months in the field to work on three interrelated projects with their Swedish counterparts: (1) a water input model for the glacier, (2) studies of the relation between glacier velocity and water pressure, and (3) subglacier till rheology. Dr. Hooke brings to this collaboration his extensive expertise in glacier dynamics and hydrology. This is complemented by Dr. Karlen's work on Holocene climate changes, glacial and deglacial chronology. Both investigators are very familiar with Storglaciaren, the field site in Sweden and have been collecting data in this region for several years. Data from Storglaciaren will contribute to overall global studies on glaciology. In particular, the study on the rheology of basal till could be applied to other glacial areas including the fast-flowing ice streams of the Antarctica. These investigations will also be useful to modelers studying climate change effects on present day ice masses.

这项为期两年的奖项支持罗杰·勒布在极地冰川学方面的合作研究。明尼苏达大学的胡克和斯德哥尔摩大学的威比约恩·卡伦。调查人员将对瑞典北部的一个小山谷冰川--斯托格拉西亚伦冰川进行研究。他们的主要目标是开发一个根据气象数据预测冰川运动的全球模型。胡克博士和他的团队，包括一名高级研究生和博士后研究员，将在这一领域花费几个月的时间，与他们的瑞典同行一起开展三个相互关联的项目：(1)冰川水输入模型，(2)研究冰川速度和水压力之间的关系，以及(3)冰川下耕作流变学。胡克博士将他在冰川动力学和水文学方面的丰富专业知识带到了这次合作中。卡伦博士在全新世气候变化、冰川和非冰川年代学方面的工作补充了这一点。这两名调查人员都非常熟悉瑞典的野外地点斯托格拉西亚伦，几年来一直在收集该地区的数据。来自Storglciaren的数据将有助于全球冰川学的整体研究。特别是，基本耕作流变学的研究可以应用于其他冰川地区，包括南极的快速冰川。这些研究也将有助于模型师研究气候变化对当今冰块的影响。
