Density inhomogeneities are one of the main factors controlling Earth's dynamics at all levels. Thus, the gravity field should be used as one of the principal constraints in understanding surface tectonics and geodynamic modelling. Furthermore, it has been realized recently that seismic tomography can not provide a complete image of the Earth interiors and some of strong density anomalies (e.g. due to composition variations) are not detected by seismic methods. Therefore, joint modelling of seismic and gravity data may significantly improve our knowledge about structure of the Earth.

Globally complete and homogenous gravity and geoid models as well as their temporal variations have been recently produced with unprecedented accuracy with the new satellite missions. These data offer a unique opportunity to better understand global Earth structure and dynamics at all levels. At the same time, novel methods of the gravity data analysis have been developed.

In this intra-disciplinary symposium we invite papers, which are focused on the interrelation between the density structure and ongoing tectonic processes at all time and space. Furthermore, we invite contributions from geophysics, geodesy and mathematics focusing on general theoretical and methodological aspects of potential fields; from theory to applications including instrumental issues. Topics of particular interest are studies of Earth's geodynamic and tectonic processes from satellite data as well as investigations related to temporal variations of the Earth gravity field in all spatial and temporal scales.
