U.S.-Sweden Cooperative Research: Relation between Water Input, Water Pressure, Surface Speed and Basal Till Deformation

这个为期两年的奖项支持Roger LeB和Roger LeB之间在极地冰川学方面的合作研究。明尼苏达大学的Hooke和斯德哥尔摩大学的Wibjorn Karlen说。调查人员将对瑞典北部的一个小山谷冰川Storglaciaren进行研究。他们的主要目标是开发一个全球模型，根据气象数据预测冰川运动。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，将在该领域花几个月的时间，与瑞典同行一起开展三个相互关联的项目：(1)冰川进水模型；(2)冰川流速与水压关系的研究；(3)冰川下土体流变学。胡克博士为这次合作带来了他在冰川动力学和水文学方面的广泛专业知识。卡伦博士在全新世气候变化、冰期和去冰期年代学方面的研究补充了这一点。两位调查人员都非常熟悉瑞典的Storglaciaren，并在该地区收集了几年的数据。从storaglaciaren获得的数据将有助于全球冰川学的全面研究。特别是基土的流变学研究可以应用于其他冰川地区，包括南极洲的快速流动冰流。这些调查也将有助于建模者研究气候变化对当前冰质量的影响。

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.
