Ice Flow History of the Thwaites Glacier, West Antarctica

View Catalog Page

Entry ID

NSIDC-0463

Summary

This data set contains past flow lines of Thwaites Glacier. The flow lines were identified using layer patterns tracked between parallel radar layers, from a radar profile of the Thwaites Glacier catchment. The radar data was run and processed by the University of Texas Institute for Geophysics. The flow lines were identified from distinct layer patterns tracked between parallel radar layers.

Data are available via FTP in ASCII text (.txt) format.
