9316807 Raymond 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. ***

这一奖项是为了支持一个对simple Dome及其周围冰流C和d之间的冰川学研究项目。这项工作的目的是描述动态环境和冰地层学特征，以帮助评估simple Dome作为一个潜在的深冰芯地点，并确定该地区冰流的配置是否与过去不同。这项工作包括在标准GPS测量的基础上，利用雷达回波测深和速度场的测定，测量冰层内层的结构和连续性。这项工作的目标与了解南极西部冰盖（WAIS）的动力学，其过去的历史和潜在的未来行为有关，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的合作项目。＊＊＊
