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.

该奖项是为了支持为期两年的合作计划，以开发数据量表，以此作为一种技术，以进一步利用高级非常高分辨率辐射计（AVHRR）传感器数据的有利特征（尤其是其高射量敏感性），以绘制极性冰纸上极性冰牌上的表面特征。 这项工作将集中于量化局部表面浮雕以及在绿地和南极洲的两个焦点区域中现有地形数据的完善。 尽管这里没有提出过现场工作，但这项工作对于东北格陵兰，Siple Coast Ice溪流和南极西部的ICE鸿沟地区的预期现场活动可能很重要。 大型冰盖内部的形态和冰动力学的表征是深层冰钻钻孔的重要组成部分。
