Cenozoic palaeoenvironment of the Southern Ocean and East Antarctica : geological and paleontological evidence from the Kerguelen Plateau, Vestfold Hills and Prince Charles Mountains ...
Southern Ocean and Antarctic sediments from the Kerguelen Plateau, Vestfold Hills and Prince Charles Mountains contain evidence that suggest climatic conditions and ice sheet volume have fluctuated during the Cenozoic. Geological and palaeontological data show that at certain intervals the Antarctic...
