Siple Dome Glaciology and Ice Stream History

9316338 Eschebel该奖项是为了支持一项对Siple Dome及其在Ice Streams C和D之间的环境进行冰川学研究的计划。 这项工作的目的是描述动态环境和冰地层，以帮助评估作为潜在的深冰芯网站的Siple圆顶，并确定该地区的冰流流的配置是否在过去与现在不同。 这项工作涉及利用雷达回波探测测量冰层内部的结构和连续性，并根据标准的全球定位系统测量确定速度场。 这项工作的目标是了解南极西部冰盖（WAIS）的动态，其过去的历史和未来的潜在行为，包括对全球海平面的可能影响。 这项工作是华盛顿大学、科罗拉多大学和圣奥拉夫学院之间的合作项目。 ***

9316338 Jacobel This award is for support for a program of glaciological studies of Siple Dome and its surroundings between Ice Streams C and D. The purpose of the work is to characterize the dynamic environment and ice stratigraphy to aid in the assessment of Siple Dome as a potential deep ice core site, and to determine whether the configuration of ice stream flow in the region was different in the past than now. The work involves measurements of the configuration and continuity of internal layers in the ice, using radar echo sounding and determination of velocity field, based on standard GPS surveying. The goals of the work are relevant to understanding the dynamics of the West Antarctic Ice Sheet (WAIS), its past history and its potential future behavior, including possible effects on global sea level. This work is a collaborative project between the University of Washington, the University of Colorado and St. Olaf College. ***
