Full description

The data include a 1:10,000 scale map of the surfical glacial and periglacial features of the Amery Oasis, East Antarctica. Features currently include:

areas covered by exposed bedrock, fluvial sediments and moraine
moraine ridges
streams (flowing during the 2003/04 season)
watercourses
lakes
cosmogenic exposure ages
degree of weathering

and includes areas of glaciers, glacial bedforms, scree and patterned ground.

Rock samples are currently held by Duanne White (as at 2015-09-23), but will eventually be archived at Geoscience Australia.
