Call for abstracts, IUGG 1999 (Birmingham, England) --------------------------------------------------- We would like to bring to your attention to the IUGG symposium outlined below. The symposium is jointly sponsored by IASPEI and IAG. We would encourage anyone interested in this area of research to talk about their work at the symposium. The deadline for submission of abstracts is 15 January 1999. Further information about IUGG 1999 can be found on the World Wide Web at http:/www.bham.ac.uk/IUGG99/ JSS31 Geodetic Constraints on Tectonic Models ---------------------------------------------- A range of geodetic observations (e.g. GPS positioning, SAR interferometry, satellite altimetry, high-resolution satellite gravity fields) can provide strong constraints on the tectonics of both continents and oceans. In parallel with the recent advances in geodetic techniques, there have been developments in methods used to make the observations more accessible to further analysis (e.g. the construction of smooth horizontal velocity fields for the continents, and the construction of marine gravity fields) as well as developments of theoretical models used to interpret the observations (e.g. dynamical models of continental deformation and mantle convection). The aim of this symposium is to stimulate interaction between workers on the observational and theoretical sides of this area of research.
