Data Set ID:

Roosevelt Island Bedrock and Surface Elevations, Version 1

This data set consists of bedrock and surface elevation readings taken by ground penetrating radar and Global Positioning System (GPS) on Roosevelt Island, an ice dome within the Ross Ice Shelf. Locations were validated by GPS readings of poles set in the surface snow. The data was collected between November and December, 1997.

Data are available via ftp, and are provided in a text file with an accompanying file that provides GPS locations. Surface and bedrock elevations are given in meters above WGS84.
