Summary: Although scientific evidence prior to that from ODP Leg 119 indicates the presence of an ice sheet on East Antarctica by at least the earliest Oligocene, the question as to the size and stability of that initial ice sheet is still contested. Current hypotheses include the presence of a small ice sheet in the earliest Oligocene with stepwise growth during the Neogene; the presence of a continental-sized ice sheet in the late Middle Eocene with no major evidence of subsequent deglaciation; and the presence of glacial ice in the earliest Oligocene with a major ice sheet during the mid-Oligocene, followed by growth and decay of several ice sheets with characteristics similar to the temperature ice sheets of the Pleistocene of North America but with changes over a longer time scale (millions of years vs. 100,000 yr). Principal results from Leg 119 suggest the presence of significant late Middle and Late Eocene glaciation in East Antarctica and the presence of a continental-size ice sheet in East Antarctica during the earliest Oligocene.
