Dynamic topography induced by global mantle flow
The picture below shows an example of computed dynamic topography due to mantle flow caused by density heterogeneities inferred from seismic tomography (left). It is compared to residual topography computed by substracting contributions due to crustal thickness variations and ocean floor age variations from actual topography (right). By backward advecting mantle density heterogeneities we compute dynamic topography and the mantle density anomalies and flow that cause it also in the geologic past - follow this link for pictures and movies. This project is done with Dietmar Müller and collaborators, especially Christian Heine.
