Ice Dynamics and Surface Glaciology along US ITASE Traverse Routes in East Antarctica
Entry ID: hamilton_0440792

Abstract: This award supports a series of field measurements that will improve our understanding of the East Antarctic ice sheet. The objectives of this project are to take advantage of the overland traverse logistics framework provided by US ITASE and to collaborate with other US ITASE investigators to calculate rates of ice sheet thickness change (mass balance) on domes, along elevation contours and along flow lines in East Antarctica using precise global positioning system methods.

Purpose: The expected results include mass balance determinations for the Ross Ice Shelf sector of the East Antarctic Ice Sheet, an improved snow accumulation map for portions of East Antarctica, the deconvolution of ice dynamics effects from climate effects in ice core records, and an analysis of glaciological conditions near the onset of streaming flow leading to large outlet glaciers.
