Numerical modeling of Mantle Convection IGPP Green Scholar Thorsten Becker uses the OptIPuter for the numerical modeling of mantle convection. Global circulation models, such as the one visualized in the 3-D volume rendering underneath Africa, are used to predict deformation in the Earth's lithosphere. Observations such as seismic anisotropy from surface waves can then be compared to modeling results, as shown in global map view for upper mantle depths around 200 km. The careful analysis of regions of match and mismatch of such comparisons allow researchers to better understand the relationship between flow and deformation, and so to gain new insights into mantle dynamics and plate tectonics. Our attempts to learn more about the effect of mantle flow on surface geology thrive on an inter-disciplinary approach, synthesizing mineralogy, seismology and geodynamics. IGPP researchers involved in this collaborative project include Donna Blackman, Gabi Laske, and Guy Masters.
