In particular, he proposes to investigate the potentially first-order effects of graviational coupling between the mantle and solid inner core and the effects of the mantle's precession on the dynamics of the fluid core. The PI also hopes to gain greater confidence in the geodynamo simulations by simulating, with a modified version of the Glatzmaier-Roberts model, a proposed laboratory experiment is being conducted by D. Lathrop at University of Maryland and is separately funded.
