MEaSUREs BedMachine Antarctica, Version 1

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, contains a bed topography/bathymetry map of Antarctica based on mass conservation, streamline diffusion, and other methods. The data set also includes ice thickness, surface elevation, an ice/ocean/land mask, ice thickness estimation errors, and a map showing where each method was utilized.本数据集隶属于美国国家航空航天局（NASA）的地球系统数据记录研发以服务研究环境（Making Earth System Data Records for Use in Research Environments，MEaSUREs）计划，包含基于质量守恒、流线扩散等方法构建的南极洲床形地形与水深地图。本数据集同时涵盖冰厚、地表高程、冰/海/陆掩膜、冰厚估算误差数据，以及标注各方法应用区域的地图。
