Glacial isostatic adjustment on a rotating earth

We extend and complete previous work to compute the influence of perturbations to the rotation vector on a suite of observables associated with glacial isostatic adjustment (GIA). We emphasize observables relevant to present and future geodetic missions (for example, present-day 3-D crustal motions, relative sea-level change and geoid or absolute sea-level variations). Our calculations adopt spherically symmetric, self-gravitating, Maxwell...
