Description
We provide a set of paleobathymetric/topographic reconstructions for the Cenozoic time (66 - 0 Ma). We have re-evaluated the evolution of the Northern hemisphere oceanic gateways (i.e. the Fram Strait, Greenland – Scotland Ridge, the Central American Seaway, and the Tethys Seaway) and embedded their tectonic histories in a new global paleobathymetry and topography model. Our new paleobathymetry model incorporates Northeast Atlantic paleobathymetric variations due to Iceland mantle plume activity, updated regional plate kinematics, and models for the oceanic lithospheric age, sediment thickness, and reconstructed oceanic plateaus and microcontinents. We also provide a global paleotopography model based on new and previously published regional models.
