The phenomenon of glacial isostatic adjustment with its unique temporal signatures is one of the great opportunities in geosciences to get information about Earth processes. It contains information about the recent climate forcing, being dependent on the geologically recent on- and off-loading of ice sheets. It gives a unique chance to study the dynamics and rheology of the lithosphere and asthenosphere with an increasing detailed modelling, and it is of fundamental importance in geodesy, since the global reference frames, Earth rotation and Polar motion are influenced by it. Analysis of data from satellite missions aimed at determining environmental change on the Earth's surface require accurate accounting of the GIA gravitational signal. For example, in order to discern present-day ice mass balance in Antarctica, Gravity Recovery and Climate Experiment (GRACE) observations must be corrected for a large, and poorly constrained, GIA signal. Modelling of GIA observables frequently incorporate features such as non-linear mantle flow and laterally heterogeneous Earth structure and may include sophisticated treatments of shoreline and ocean-load evolution. Contributions are welcomed on all aspects of GIA observation and modelling, including recent advances in modelling techniques, inferences of Earth structure and rheology, and analysis of observations that require correction for the GIA signal in order to isolate environmental change.

This session is a venue to present recent results of the Dynamics of Quaternary Climate (DynaQlim) project and of COST Action ES0701 “Improved Constraints on Models of GIA”.
