West Antarctic Glaciology III

这一奖项是为了支持对南极西部冰原与罗斯冰架相连部分的研究。卫星图像分析、地面测量和机载和地面系统的雷达探测构成了这项研究的必要要素。这些活动是简单海岸项目和新的SeaRISE倡议的重要组成部分，其目标是：1)确定南极西部冰盖简单海岸地区的结构和物质平衡；2)确定该地区冰流的物理控制；3)利用数值模式预测该地区未来的行为。这些模型将通过以下方式得到加强：1)完成所有冰流集水区的调查，2)确定冰流D和E的地表速度，3)测量冰流D和E的流量，4)利用卫星图像检查地表波动区域的冰流流量。5)量化接地线上游接地区地表与床层之间的相对运动。

This award is for support of research to study the portion of the West Antarctic Ice Sheet which feeds in to the Ross Ice Shelf. Satellite image analysis, ground surveying, and radar soundings by both airborne and ground-based systems comprise the necessary elements of this research. These activities are an essential part of the Siple Coast Project and the new SeaRISE initiative which have as goals: 1) Determination of the configuration and mass balance of the Siple Coast region of the West Antarctic ice sheet, 2) Determination of the physical controls of ice flow in this region, and 3) Prediction of the future behavior of this region using numerical models. These models will be enhanced by: 1) Completion of the surveys in the catchment areas of all the ice streams, 2) Determination of surface velocities in ice streams D and E, 3) Measurements of the discharge flux of ice streams D and E, 4) Examination of ice stream flow in the area of a surface undulation using satellite imagery, 5) Quantify the relative motion between the surface and bed in the grounded region just upstream of the grounding line.
