Paleobathymetry and sediment thickness of the Southern Ocean since 34 Ma
Paleobathymetric models and sediment thickness estimations give insight into the development of the Antarctic Ice Sheets, Southern Ocean current systems and opening of the Southern Ocean Gateways since the Eocene/Oligocene Boundary. A more sophisticated assessment of the paleobathymetry and the sedi...

Paleobathymetric models and sediment thickness estimations give insight into the development of the Antarctic Ice Sheets, Southern Ocean current systems and opening of the Southern Ocean Gateways since the Eocene/Oligocene Boundary. A more sophisticated assessment of the paleobathymetry and the sediment deposition in the Southern Ocean are essential for robust reconstructions of paleoclimate and paleooceanographic scenarios.For this reconstruction, we used all available reflection seismic data (refer to Hochmuth et al.

Paleobathymetric grids are calculated using the backstripping method as implemented in the BalPal code (Wold et al. 1992). Plate tectonic reconstruction follows Müller et al. (2018).
