Abstract:

This contract used to support work on several different problems 1 Develop models to estimate the effects of atmospheric pressure loading on surface displacements and surface gravity. 2 Investigate the effects of aspherical core structure on the forced nutations. 3 We studied the possibility of aspherical structure inside the core, and its possible implications for geodetic and seismic constraints on the core-mantle boundary topography. Begin a study of the oceans response to pressure, and its implications for certain geodetic observations. So far, it has concentrated on trying to assess the accuracy of pressure data sets over the ocean. 5 Use monthly, global tide gauge data to investigate certain long period oceanic disturbances which have implications for the interpretation of geodetic eg., rotation, earth tide, crustal dynamics data.
