Perturbations in the Earth's rotation induced by internal density anomalies: implications for sea-level fluctuations
Résumé
The effects of internal mass anomalies on the Earth's rotation are analyzed within the framework of linearized Liouville equations and Maxwell rheology for the mantle. Our approach is appropriate for a simplified modeling of subduction. Sea-level fluctuations induced by long-term rotational instabilities are also considered. -from Authors
