Although understanding the response of ice sheets to a changing climate is a pressing issue of this century, our current knowledge of past ice-sheet changes remains limited by data sparsity. Sea-level variability provides direct insight into the history of ice volume fluctuations. Nevertheless, these local observations of sea level do not scale directly with ice volume variations. As ice sheets grow and decay over a glacial cycle, loads of ice, water, and sediment are redistributed over the Earth's surface. The redistribution of mass perturbs the Earth’s rotation axis and gravitational field through solid Earth deformation, producing a spatially variable pattern of sea-level change.
