Abstract:
Glacial geomorphological data from the Ellsworth Mountains, Weddell Sea embayment. Satellite imagery and aerial photography, ground truthing, surveying and GPS traverses were used for geomorphological mapping. Additional photographic and weathering data were used to complement the field work. The project resulted in one of the most detailed geomorphological studies of any part of the WAIS (West Antarctic Ice Sheet), as well as the most comprehensive coverage for cosmogenic isotope analysis.
