Deep Earth Dynamics Modeling convection in the mantle requires numerical methods capable of handling extreme changes in material properties, time-dependent flow, and complex, heterogeneous structures. Geodynamical simulations allow us to address such outstanding questions as: What is the fate of lithospheric slabs as they descend into the deep mantle? What is the morphology and significance of rising plumes and in what regions of the mantle do they originate? Are there distinct geochemical reservoirs in the mantle? Advances in computation generate huge amounts of complex data, posing a significant visualization challenge that requires effective data exploration. In the KeckCAVES, we are developing tools and methods for integrating disparate geoscience information using interactive visualization. An integrated, interactive, and immersive visualization system is being developed that will allow scientists to design initial conditions for geodynamical simulations, to monitor and steer the progress of ongoing numerical simulations, and to interpret the resulting models. This steering will be performed by interactively manipulating simulation boundary conditions to fit data from seismic observations, such as modeling the shape of blobs or piles of material.
