GP51A:
The Polar Geomagnetic Field in the Northern and Southern Hemispheres


Submit an Abstract to this Session


Session ID#: 45207

Session Description:
Historical observations, paleomagnetic data and geodynamo theory attest to the unique properties of the geomagnetic field of Polar Regions. Observations from Polar Regions are challenging, yet they can provide a unique vantage point to obtain information on the dynamics of the geodynamo. We solicit both observational (satellite, historical, archeomagnetic and/or paleomagnetic records) and modeling results that constrain the polar geomagnetic field of both hemispheres and provide insights into the recent migration of the North and South Magnetic Poles, geomagnetic features such as the reversed flux at the core mantle boundary, the high latitude flux lobes, the polar vortex, the tangent cylinder, high latitude jets and how these impact our understanding of geomagnetic changes on all timescales. We also solicit studies on the impact of the polar geomagnetic field on Earth’s near space environment, Earth surface processes and the use of the polar paleomagnetic record in magnetic stratigraphy at all timescales.
