We infer the radial viscosity structure of the Earth's mantle from observations of long-wavelength geoid, glacially-induced sea-level changes, and changes in the Earth's rotation and gravitational field. We employ a combination of forward and formal inverse modeling of long-term mantle circulation driven by large-scale density differences deduced from seismic tomography. Based on the resulting unscaled mantle viscosity profiles, we model the time-dependent glacial isostatic adjustment of the...[Show more]
