Early Pliocene alpine glaciation in Antarctica : terrestrial versus tidewater glaciers in Wright Valley

Climate change and variability. Special issue

Description :
The AA. present results of a test of the Hall et al. (1993, 1997) hypothesis that, in the early Pliocene, the alpine glaciers terminated at the edge of a Wright Valley fjord. The test consisted of re-mapping the surficial geology of the same 5 alpine glaciers mapped by Hall et al. (1997). The AA. used recently available microtopographic data derived from the Light Detection and Ranging (LIDAR) technique in addition to stereoscopic analysis of aerial photographs and the evidence of Hall et al. (1993). Further clarification of the frontal geometries and boundary conditions of the Wright Valley alpine glaciers in the early Pliocene is a prerequisite to modeling their early Pliocene fluctuations and reconstructing paleoclimate.
