US International Trans-Antarctic Scientific Expedition (US ITASE): GPR Profiles and Accumulation Mapping
Listed in NASA Earthdata CMR
Snow accumulation rates typically show high variability over short distances.
Description
This data set contains accumulation rates using ground-penetrating radar (GPR) to detect isochronal layers in the firn in West Antarctica. These layers were then dated using results from ice core analyses.
These data show that accumulation rates along this profile have decreased in recent decades. The radar profile extends between two ice core sites taken along one of the US-ITASE traverse routes. Data are available via FTP in both ASCII and Excel formats.
