This award supports the analysis and intepretation of glaciological data, primarily from Greenland and Alaska. The project will consist of three parts: 1) The analysis of glacier facies as a classification for all glaciers. It will focus on the importance of meltwater percolating and freezing within snow to both the heat and mass balance of glaciers and the extent to which facies boundaries can be determined from satellites and aircraft. 2) A synthesis of existing knowledge about snow accumulation on the Greenland Ice Sheet based on data from pit studies, snow and ice cores, and meteorological stations. This will demonstrate the extent of orographic control on the distribution of snow accumulation. 3) An analysis of snow pit and core data from the summit of Mt. Wrangell, Alaska, obtained between 1961 and 1989 to define the snow stratigraphy's relation to avaialable climatological data.

该奖项支持对冰川学数据的分析和解释，主要来自格陵兰岛和阿拉斯加。该项目将包括三个部分：1)冰川相分析作为所有冰川的分类。它将侧重于融水在雪中的渗透和冻结对冰川的热量和物质平衡的重要性，以及从卫星和飞机可以确定相边界的程度。2)基于坑研究、雪、冰芯和气象站数据的格陵兰冰盖积雪知识综合。这将证明地形对积雪分布的控制程度。3)通过对1961 ~ 1989年阿拉斯加Wrangell山顶雪坑和雪芯资料的分析，确定了积雪地层学与现有气候资料的关系。
