Satellite Image Analyses for US ITASE Route Selection and Sampling Strategy

该奖项是对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的奖励。图像将被用来选择最安全的穿越路线和良好的冰芯钻探位置。雷达卫星图像被认为是绘制裂缝图的主要工具。寻找好的冰芯钻探地点将包括确定当地的坡度波动、冰流方向、埋藏的萨斯特鲁吉的方向和强度以及潜在钻探地点附近过去融化的证据。这项工作与理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地球物理研究中心的一部分收集的冰芯记录。

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.
