Glacial and tectonic development of the Antarctic Peninsula
Intermediate resolution seismic data were used to investigate the glacial history of the Pacific-Antarctic continental shelf. The objective was to determine the nature of ice sheet erosion and deposition on the continental shelf and to use these observations to reconstruct the glacial history of the...
