Doctoral dissertation, Harvard University.http://dissertations.umi.com/gsas.harvard:11684http://nrs.harvard.edu/urn-3:HUL.InstRepos:12274557This thesis focuses on the long-term rotational stability of the Earth and terrestrial planets. One important class of perturbation is a reorientation of the solid planet with respect to a rotation pole that remains fixed in an inertial frame. These motions are driven by mass redistribution within or on the surface of the planet (e.g. glaciation, mantle convective flow). Long-term changes in the orientation of the rotation pole are called True Polar Wander (TPW).en-USGeophysicsAstrophysicsEarth Rotation VariationsIce AgeLithosphereMartian OceanPlanetary RotationTrue Polar WanderThesis or Dissertation2016-06-04
