This award is for support for a two year collaborative program for the development of data cumu-lation, as a technique to further exploit the favorable characteristics (in particular its high radio-metric sensitivity) of the Advanced Very High Resolution Radiometer (AVHRR) sensor data for mapping surface features on the polar ice sheets. The work will focus on the quantification of local surface relief and on the refinement of existing topographic data over the two focus areas of Green-land and Antarctica. Although no field work is proposed here, this work is potentially important to anticipated field activity in northeast Greenland, the Siple Coast ice streams and the ice divide area in West Antarctica. Characterization of the morphology and ice dynamics of the interior of large ice sheets is an important component of site selection for deep ice-core drilling.

该奖项旨在支持为期两年的数据累积开发合作项目，该项目是进一步利用高级甚高分辨率辐射计 (AVHRR) 传感器的有利特性（特别是其高辐射测量灵敏度）的技术用于绘制极地冰盖表面特征的数据。 这项工作将重点关注格陵兰岛和南极洲两个重点区域当地地表地形的量化和现有地形数据的细化。 虽然这里没有提出实地工作，但这项工作对于格陵兰岛东北部、西普尔海岸冰流和南极洲西部冰分水区的预期实地活动可能很重要。 大冰盖内部形态和冰动力学的表征是深部冰芯钻探选址的重要组成部分。
