Описание: The theory of plate tectonics has become the foundation of modern Earth sciences. However, many questions remain on the fate of subducted plates and their effects on the Earth's surface geology. Answers to this question begs for a quantitative understanding of the internal dynamics of the solid Earth, a process only becoming tangible in the past decade due to the fast development of supercomputing. At the University of Illinois, my group has been using Blue Waters to construct such quantitative and deterministic geodynamic models. By now, we have developed the largest in-scale models of its kind, with up to 10,000 MPI cores for a single simulation. Most of our models use data assimilation that merges data from geology, tectonics and geophysics into the same geodynamic framework. Notable examples include our simulation of subduction and convection on a global scale, mantle processes below Yellowstone, and the long-term evolution of continental lithosphere.
