Ocean Drilling Program: Kerguelen-Heard Plateau - Cenozoic Variations in Southern Ocean Currents and Relationship to Climatic ChangesEntry ID: ASAC_259
Abstract: This data were collected as part of the Ocean Drilling Program. All data were collected on Leg 119. The cruise for Leg 119 began at Port Louis Harbor, Mauritius, and finished at the Port of Fremantle, Australia. The objective was to complete a transect, along with Leg 120, to study the Late Cretaceous to Holocene palaeoclimatic history of East Antarctic, tectonic history of the Kerguelen ... Plateau, and the late Mesozoic rifting history of the Indian plate from East Antarctica.
Samples are sediments. Good calibration standards for sediments not available.
More information can be obtained from the Ocean Drilling Program website.
The data obtained from the drilling is available on the Ocean Drilling Program website (see Download Paleontology Data).
From the abstract of one of the papers:
The timing and nature of the initiation of the Antarctic Ice Sheet is the subject of considerable discussion. Before Leg 119, the earliest known unequivocal Cenozoic glacial sediments were discovered in a Lower Oligocene sequence from the Ross Sea. Quartz grains of Eocene age from the Subantarctic Pacific Ocean were inferred from their grain texture to be ice-rafted. Previous results obtained by Leg 113 in the Weddell Sea indicate that glaciation at sea level first occurred during the late early Oligocene on East Antarctica and during the late Miocene on western Antarctica. Our new results show that glaciation is present during the earliest Oligocene and possibly the late Miocene.
