Our understanding of Earth's inner and outer core is progressing at a rapid pace thanks to cross-fertilization between a number of observational, theoretical and experimental disciplines.

Improved seismic observations continue to provide better images of the core and prompt refinements in structural and geodynamic models. Mineral physics provides constraints for dynamic, structural, and thermodynamic models. The heat budget of the core, paleomagnetic observations, and models promote the exploration of new dynamo mechanisms. Geomagnetic observations from both ground and satellite, along with magneto-hydrodynamic experiments, provide additional insight to our ever expanding view of Earth's core.

This session welcomes contributions from all disciplines, as well as interdisciplinary efforts, on attempts to proceed towards an integrated, self-consistent picture of core structure, dynamics and history, and to understand its overwhelming complexity.
