Based on the IAG scientific assembly in Rio de Brazil, this volume combines papers in the fields of gravity and geoid, geodynamics, and geodesy in Antartica. The volume contains papers on recent progress in absolute and relative gravimetry, on models of the global gravity field, theoretical developments in physical geodesy, and many examples of regional gravity field and geoid models. Geodynamics chapters include papers on earth rotation and geopotential variations, reference frames and global deformations, as well as a section on the combination of space and terrestrial methods for deformation observations. The current status of geodesy in Antarctica is illustrated by a number of papers.
The changing role of gravity reference networks; past and future developments in geopotential modelling; a priori estimates of the solution of the geodetic boundary value problem; the European gravimetric quasigeoid EGG97 - an IAG supported continental enterprise; metrology of the Earth's rotation over 1988-1997; absolute positioning, tectonic plate motions and polar motion determination with the DORIS system; multi-parametric experiment for observing crustal deformations in southern Brazil; the ice-age geodynamics of Antarctica.
