The description of the session is given below. We would like to draw your attention to this session and encourage you to participate in it. The deadline for submitting abstracts is 15 January 2007. Hope to see you in Vienna! Best regards, Richard Gross and Hans-Peter Plag ................................. G4/GD17: What constraints do earth rotation, shape, and gravity measurements place on the dynamical processes of the solid earth? Measurements of the Earth´s rotation, shape, and gravity provided by the Global Geodetic Observing System show that they change on a wide range of time scales reflecting the wide range of processes affecting them, 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 frequencies of the resonances in the Earth´s rotation, including the Chandler wobble, the free core nutation, the free inner core nutation, and the inner core wobble, depend upon the internal structure and constitution of the Earth. Measurements of the Earth´s rotation, shape, and gravity 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, the tilt and rotation of the inner core, and the strength of the magnetic field at the inner core and core-mantle boundaries. This session will be a forum for discussing the use of Earth rotation, shape, and gravity measurements to constrain the structure and dynamical processes of the solid Earth. Richard S.
