PhD-project title: Paleogeography and paleotopography: dynamic constraints for paleoclimatic simulation at long timescales
The paleobathymetric reconstruction of the Southern Ocean is one of the key elements in circumantarctic paleoclimate modelling in terms of boundary conditions. Still, the plate-kinematic rotations of plates and plate segments of the Southern Ocean are far from being solved. The main task of this project is to fill the gaps by refining existing oceanic paleo-age and plate-kinematic grids and complete the integration of paleogeographic grids of the Southern Pacific region with that of the Australian-Antarctic Basin and the Tasman Sea.
In a second step, the paleobathymetry of the sea floor will be modelled using state-of-the-art tools and techniques. Special attention will be paid to the opening of oceanic gateways (e.g. Drake Passage, Tasmanian Gateway), as they provide deep-water pathways and thus have a major impact on the global oceanic circulation.
In the final stage, the new boundary conditions will be incorporated in the simulation of regional and global paleooceanographic and paleoclimatic scenarios (e.g. development of deep-sea currents, onset of Antarctic glaciation etc).
