Abstract:
Three recent Ocean Drilling Program (ODP) cruises--Leg 178, Antarctic Peninsula; Legs 119 and 188, Prydz Bay--have drilled various parts of the Antarctic continental margin in an effort to constrain the history of the Antarctic Ice Sheet. Integration of geophysical, biofacies, and sedimentological data from these ODP legs suggests that a very similar style of continental margin growth has occurred along the Antarctic continental margin. Data from the Antarctic continental margin suggest that the shelf aggrades ("upbuilds") during periods of ice front retreat, whereas the slope progrades ("outbuilds") during episodes of ice advance to the shelf break. Because other glaciated continental margins have glacial marine successions similar to that of the Antarctic continental margin, it may be that a common or "unified" model of glaciated margin deposition exists, regardless of latitude and geological age.
