Geomagnetism

Geoscience Australia maintains a national network of geomagnetic observatories which forms part of a global observatory network. Data measured at these observatories show how the Earth's magnetic field changes in the Australian region due to processes taking place beneath the Earth's surface, in the upper atmosphere and in the Earth-Sun space environment. These data are used in mathematical models of the geomagnetic field, in resource exploration and exploitation, to monitor space weather, and for scientific research. The resulting information can be used for compass-based navigation, magnetic direction finding, and to help protect communities by mitigating the potential hazards generated by magnetic storms. Geoscience Australia also promotes public safety through the provision of compass and magnetometer calibration services.
