| Zusammenfassung |
| The process of Cenozoic Antarctic glaciation during Eocene-Oligocene transition
(around 34 Ma before present) is investigated utilizing a version of the Hamburg
Planet Simulator coupled with surface and sub-surface compartments of the
University of Victoria Earth System Climate Model.
A series of time slice experiments supports the hypothesis derived from recent
analysis of oxygen isotope ratios that the joint effect of orbital configuration,
decreased atmospheric carbon dioxide and opening of the Drake passage and the
Australia-Antarctic gateway not only leads to Antarctic, but to a rapid bipolar
glaciation. |
