Subglacial morphology in northern Palmer Land, Antarctic peninsula

Auteur :
CRABTREE, R. D.

Description :
Ice thickness and surface-elevation data gathered from radio echo flights over the Antarctic peninsula are presented as profiles for five major outlet glaciers in northern Palmer Land and as contour maps for an area of 8 000 km to the east of George VI Sound-Glacier profiles appear to be closely related to ice discharge especially to convergent and divergent flow. Comparison of subglacial topography with geological evidence of faulting suggests that the area around George VI Sound is a region where structure is an important influence on the pattern of glacial erosion.
