DI004:
Connecting the evolution of the Earth’s magnetic field and the dynamics of the deep interior





Session ID#: 23048

Session Description:
Observations of the Earth’s magnetic field provide a window into the internal dynamics of the deep interior. Advances in paleomagnetic, archeomagnetic, observatory, and modern satellite measurements reveal that the geodynamo is ancient and seemingly persistent, yet the detail of how it operates and manifests in changes on yearly to millennial to million year timescales remain poorly known. Modelling the conditions representative of Earth’s core remain challenging, yet it is only by constraining such models with observations that a complete understanding of the core will emerge. This session seeks to bring together perspectives from the observational community with those from the modelling community to convene on the current state of the geodynamo and its evolution. We invite contributions that advance our understanding of the evolution of the field - from paleomagnetic to modern measurements - along with numerical models or theory that provide insight into the deep interior's history and dynamics.
