This award is for a program of satellite image analysis in support of the U.S. component of the International Trans-Antarctic Scientific Expedition (ITASE). Imagery will be used to select the safest traverse routes and good locations for ice core drilling. RADARSAT imagery is proposed as the primary tool for crevasse mapping. The search for good ice core drilling sites will involve determining local slope fluctuations, ice flow directions, orientation and intensity of buried sastrugi and evidence of past melt near potential drill sites. The work is directly relevant to understanding the mass balance of the Antarctic Ice Sheet and will help in the interpretation of the ice core records collected as part of ITASE.

该奖项是为支持国际跨南极科学考察（ITASE）美国部分的卫星图像分析计划而颁发的。 图像将用于选择最安全的穿越路线和冰芯钻探的良好位置。 建议将雷达卫星图像作为裂缝测绘的主要工具。 寻找良好的冰芯钻探地点将涉及确定当地的坡度波动、冰流方向、埋藏的雪层的方向和强度以及潜在钻探地点附近过去融化的证据。这项工作与了解南极冰盖的物质平衡直接相关，并将有助于解释作为国际空间地球物理学研究所一部分收集的冰芯记录。
