Preliminary global paleogeographic maps through the Greenhouse-Icehouse transition: forcing of the Drake Passage and Asian Monsoons.
International audience Paleogeographic maps are essential for understanding Earth dynamics. They provide the necessary boundaryconditions for climate and geodynamic modeling, surface processes and biotic interactions. In particular, theopening and closing of ocean gateways and the growth of major mo...
