Collaborative Research-New Applications of AVHRR to the Study of Small Scale Ice Sheet Surface Morphology: A Window on Regional Ice Dynamics

该奖项是为了支持一项为期两年的数据积累合作计划，作为一项技术，进一步利用先进甚高分辨率辐射计（AVHRR）传感器数据的有利特性（特别是其高辐射度量灵敏度），绘制极地冰盖表面特征。这项工作的重点是当地地表起伏的量化和对绿地和南极洲两个重点地区现有地形数据的改进。虽然这里没有提出实地工作，但这项工作对格陵兰岛东北部、简单海岸冰流和南极洲西部冰分水岭地区的预期实地活动具有潜在的重要意义。大冰盖内部的形态和冰动力学特征是深冰芯钻探选址的重要组成部分。

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.
