G11A:
Earth and Planetary Rotation: From Core to Crust Posters

Submit an Abstract to this Session



Session ID#: 22871

Session Description:
The Earth's rotation changes on a wide range of time scales, reflecting the wide range of processes affecting it, from external tidal forces to surficial processes involving the atmosphere, oceans, and hydrosphere to internal processes acting both at the core-mantle boundary as well as within the solid Earth itself. In addition, the periods of the resonances in the Earth's rotation depend upon the internal structure and constitution of the Earth. Observations of the Earth's rotation can therefore be used to place constraints on a wide range of dynamical processes of the solid Earth, including glacial isostatic adjustment, mantle anelasticity, core-mantle coupling, core flattening, core angular momentum, torsional oscillations of the core, and the strength of the magnetic field at the inner core and core-mantle boundaries. This session is a forum for discussing the use of rotation measurements to constrain the structure and dynamical processes of the Earth and other planets.
