The first half deals with the Cenozoic glacial record of Antarctica, and the second half focuses on the Neoproterozoic glacial record of Rodinia. The glacially-influenced Cenozoic continental margin of Antarctica shows a large-scale subsurface seismic stratigraphy consisting of flat-lying topsets recording episodic aggradation of the continental shelf, that rest on seaward-dipping, wedge-shaped foresets formed by the progradation of the continental slope. Strata form topsets record aggradation by till deposition alternating with glacial-marine sedimentation. Strata from foresets record bedris flows and turbidity currents on the active slope close to a source of poorly-sorted glacial debris such as an ice sheet margin reaching the shelf break.
