Geomorphology of the onset area of a paleo-ice stream, Marguerite Bay, Antarctic Peninsula.

The article outlines the research conducted by John B. Anderson and colleagues on the geomorphology of palaeo-ice stream of the onset area of Marguerite Bay in Antartic Peninsula. Result shows that both glacial and melt-water erosion shows the onset area of the ancestral ice stream. The large structures indicate that they formed over repeated glacial cycles that occurred during the Last Glacial Maximum. It reveals that those glacially sculptured geomorphic figures within the area co-exist with anastomosing, radial and relatively straight channels which become increasingly focuses in a seaward direction.
