Siple Dome Glaciology and Ice Stream History

9316338雅各布斯该奖项是为了表彰对Siple Dome及其冰流C和D之间的周围地区的冰川学研究计划。这项工作的目的是描述Siple Dome的动态环境和冰层，以帮助评估Siple Dome作为潜在的深层冰核地点，并确定该地区过去的冰流形态是否与现在不同。这项工作包括利用雷达回波探测测量冰层内部层的形状和连续性，并在标准GPS测量的基础上确定速度场。这项工作的目标与了解西南极冰盖(WAIS)的动态、其过去的历史及其未来的潜在行为，包括对全球海平面的可能影响有关。这项工作是华盛顿大学、科罗拉多大学和圣奥拉夫学院的合作项目。***

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. ***
