Histories of Accumulation, Thickness, and WAIS Divide Location, Antarctica

This data set contains radar internal layer and ice sheet topography data for two sites in Antarctica, along with associated model results from two studies. This project used geophysical inverse theory and a 2.5 D flowband ice-flow forward model to extract robust transient accumulation patterns from multiple deeper layers. Histories of divide migration, or the movement of the ice sheet and ice-surface evolution are also provided. The data used to solve the inverse problem, and the model solutions are provided. Internal layers, modern ice-surface velocities, and modern ice-sheet geometry at Taylor Mouth are available, as well as the pattern of accumulation inferred by Waddington et al. (2007). Data are available via FTP in Matlab (.mat) format. Supporting information is available as text files (.rtf and .txt).本数据集包含南极洲两个研究站点的雷达探测冰内部层与冰盖地形数据，以及两项相关研究的配套模型结果。本项目采用地球物理反演理论与2.5维流带冰流正向模型，从多层深部冰层中提取出可靠的瞬态积累模式。同时，本数据集还提供了冰盖分界迁移（即冰盖运动与冰面演化）的历史记录，以及反演问题求解所用的原始数据与模型解。此外，泰勒河口（Taylor Mouth）处的冰内部层、现代冰面流速、现代冰盖几何形态，以及Waddington等人（2007）推断的积累模式均已收录其中。 数据集可通过FTP协议获取，格式为Matlab (.mat)文件。辅助信息以文本文件（.rtf与.txt）形式提供。
