Applications of Historical and Recent Satellite Data Sets for Geophysical Studies of the Modern Greenland Ice Sheet

主要研究人员将编制20世纪60年代初在格陵兰冰盖上获得的历史卫星数据的数字拼接。这些数据是作为Argon项目的一部分获得的，最近被解密供科学界使用。它们适用于地球偏远地区，特别是极地地区的地质和冰川学研究。他们将尝试获取从1962年至1964年在格陵兰岛收集的所有历史卫星图像。他们将利用卫星位置知识、可用的数字高程模型（dem）和可用的地面控制对每张图像进行正校正。至少两个覆盖整个格陵兰岛的数字马赛克将从正射电正校正数据中编译出来。马赛克将作为CDROM分发给其他用户。个人矫正将通过网络目录和浏览器进行。完成的马赛克将相互比较，并与最近编制的格陵兰岛图像地图进行比较。研究结果将用于研究冰盖边缘的变化、沿海冰川的裂冰锋、冰盖的运动和动力学。

The Principal Investigators will compile digital mosaics of historical satellite data acquired during the early 1960s over the Greenland Ice Sheet. These data were acquired as part of the Argon project and were recently declassifed for use by the science community. They are applicable to geological and glaciological studies of remote parts of the Earth and particularly to the polar regions. They will attempt to acquire all historical satellite imagery collected over Greenland from 1962-1964. They will orthorectify each image using knowledge of the satellite position, available Digital Elevation Model (DEMS), and available ground control. At least two digital mosaics covering all of Greenland will be compiled from the orthorectified data. The mosaic will be distributed to other users as a CDROM. Access to individual orthorectified will be made through a web-based catalogue and browser. The completed mosaics will be compared to each other and to more recently compiled image maps of Greenland. The result will be used to study changes in the ice sheet margin, calving front of coastal glaciers, ice sheet motion and dynamics.
