Geology datasets in North America, Greenland and surrounding areas for use with ice sheet models

This archive contains data files for the sediment properties (distribution and grain size) and bedrock geology for the areas covered by North American ice sheets (including Greenland and Iceland). These datasets are distributed as shapefiles and NetCDF files. These files are intended for use in ice sheet models.

本归档文件包含覆盖北美冰盖（含格陵兰岛与冰岛）区域的沉积物属性（分布与粒度）及基岩地质数据文件。本数据集以形状文件（shapefile）与网络通用数据格式（NetCDF）文件形式分发，此类文件专为冰盖模型的应用场景设计。
