Spikes, V.B., G.S. Hamilton, S.A. Arcone, S. Kaspari, and P.A. Mayewski. 2004. Variability in Accumulation Rates from GPR Profiling on the West Antarctic Plateau. Annals of Glaciology 39. In Press.Snow accumulation rates typically show high variability over short distances. 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.VIEW RELATED INFORMATIONhttps://doi.org/10.7265/N5GH9FV6DocumentationGET DATAhttp://www.usap-dc.org/view/dataset/609269Get External DataPROJECT HOME PAGEhttp://www.earthscienceagency.com/products/absolute_earth/antarctic_snow_accumulation/Absolute Earth™ Antarctic Snow AccumulationCEOS IDN DIFVERSION 9.92005-04-062023-05-23NSIDCVersion SummaryNSIDCMinor VersionNSIDCCurrent Version1NSIDCFull Dataset CitationSpikes, V.
