View Catalog Page

Entry ID

NSIDC-0518

Summary

This data set contains subglacial water flow paths beneath Thwaites Glacier, West Antarctica, interpreted from ice thickness and bed elevation measurements collected between 7 December 2004 and 31 January 2005 by the Airborne Geophysical Survey of the Amundsen Embayment (AGASEA) expedition. Data consist of an ASCII text file with geographical coordinates, hydraulic head, and bed and surface elevations, and a corresponding .pdf map.

Data are available via FTP.
