Summary: | Understanding the evolution and dynamics of the Antarctic cryosphere, from its inception during the Eocene–Oligocene transition (~34 Ma) through the significant subsequent periods of likely coupled climate and atmospheric greenhouse gas changes, is not only of major scientific interest but also is of great importance for society. Drilling the Antarctic Wilkes Land margin along an inshore to offshore transect was designed to provide a long-term record of the sedimentary archives of Cenozoic Antarctic glaciation and its intimate relationships with global climatic and oceanographic change. The principal goals were (1) To establish the timing and nature of the first arrival of ice at the Wilkes Land margin inferred to have occurred during the earliest Oligocene (reflecting Oligocene isotope Event 1 around ~34 Ma), (2) To reconstruct the nature and age of the changes in the geometry of the progradational wedge interpreted to correspond with large fluctuations in the extent of the East Antarctic Ice Sheet and ... |
