GEODYNAMICS.

Abstract

The Geodynamics Workshop at the Airlie House, Airlie, Virginia, in February 1983 was sponsored by the Earth Science and Applications Division of the Office of Space Science and Applications, National Aeronautics and Space Administration. The Workshop participants reviewed and discussed the status and accomplishments of space geodynamics projected to the year 1988. These included the expected achievements in measuring contemporaneous relative motions of several of the major plates (North American - Pacific, Nazca - South American, North American - Eurasian); epoch measurements of other plate combinations (Aegean - Eurasian, Caribbean - North American - South American) and determination of strain accumulation rate in the western U. S. It also included dramatic improvement in the ability to measure polar motion and changes in the length of day and the correlation of these phenomena with geophysical phenomena such as changes in average zonal wind and mean sea level, redistributions of the Earth's mass. In addition, significant results will have been achieved in the analysis of the Earth's gravity and magnetic fields.
