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. The broad aim is to understand the relations between upper mantle dynamics, mantle and lithosphere composition, and their physical properties, such as temperature and rheology, in order to study GIA, Quaternary climate variations and Weichselian (Laurentide and other) glaciations during the late Quaternary. The ILP regional coordination committee DynaQlim is a co-operation forum for these studies.
This Project DynaQlim related session, co-organized by Geodesy (G), Geodynamics (GD),Climate: Past, Present, Future (CL), and Geochemistry, Mineralogy, Petrology & Volcanology (GMPV), provides a forum for interdisciplinary discussions on the current status and achievements concerning following topics
- Glacial Isostatic Adjustment, observations and modelling
- Gravity change and uplift
- Further development of 3-D Earth modelling
- Physical and thermal properties of the lithosphere and asthenosphere
- Glaciation history and paleoclimate
- Ocean dynamics
