Englacial Layers and Attenuation Rates across the Ross and Amundsen Sea Ice-Flow Divide (WAIS Divide), West Antarctica

View Catalog Page

Entry ID

NSIDC-0470

Summary

This data set contains the results of a model study of spatial variations of ice temperature and subglacial conditions using available ice-penetrating radar data around a future deep ice coring site near the Ross and Amundsen flow divide of West Antarctic Ice Sheet. The model data are based on radar data collected by the Support Office of Aerogeophysical Research (SOAR) at the University of Texas, and the University of Washington, in 2000. The data include values for attenuation estimates for individual radar profiles.

Data are available via FTP in MATLAB (.mat) and Portable Document (.pdf) formats.
