摘要: 冰流速是反映在全球气候变化条件下南极冰盖变化及其稳定性最直接和最基本的指标之一,也是精确估算南极冰盖对全球海平面上升贡献的关键数据之一。光学遥感影像因其空间覆盖广、时间和空间分辨率高等优势,是南极冰流速大规模提取的重要数据源。本文首先对现有利用光学遥感影像进行南极冰流速提取的方法进行了综述,介绍了相关的软件和工具。然后,总结了20世纪60年代以来基于光学遥感影像生成的南极冰流速产品,并对南极典型区域的冰流速产品在物质平衡估算、冰架长时序变化监测等方面的应用进行了分析。最后,总结了光学遥感影像用于南极冰流速提取的优势及未来的发展趋势。

Abstract: Ice velocity is a direct and essential indicator of the stability of Antarctic ice sheet in response to global climate change. It is also one of the crucial data to accurately estimate the contribution of the Antarctic ice sheet to global sea level rise. Optical remote sensing imagery is an important data source for large-scale extraction of Antarctic ice velocity because of the advantages of data acquisition in fine temporal and spatial resolution. In this paper, we review the existing methods of Antarctic ice velocity reconstruction by using optical images, introduce relevant software and tools, and summarize Antarctic ice velocity products generated based on optical remote sensing images from 1960s to present. Furthermore, we demonstrate applications of the ice velocity products in some typical areas, such as mass balance evaluation, long time series changes monitoring of ice shelves, etc. Finally, the advantages and future development trends of optical remote sensing images for Antarctic ice velocity reconstruction are summarized.

Key words: optical remote sensing imagery, Antarctica, ice velocity, image correlation, feature tracking
