Polarity reversals of the geomagnetic field are a major feature of the Earth's dynamo.
Questions remain regarding the dynamical processes that give rise to reversals and the …

The dipole moment of Earth's magnetic field has decreased by nearly 9\% over the past 150
years and by about 30% over the past 2,000 years according to archeomagnetic …

More than 400 years ago William Gilbert said, ÒThe Earth itself is a great magnet. Ó Today,
we know that it is also a great magnetic tape recorder. This work is a comprehensive, up-to …

Direct observations of the geomagnetic field show that secular variation is strong in the
Atlantic hemisphere, and comparatively reduced in the Pacific region. The dipole has been …

The strength of the geomagnetic field has decreased rapidly over the past two centuries,
coinciding with an increasing field asymmetry due to the growth of the South Atlantic …

The Swarm mission was selected as the 5th mission in ESA's Earth Explorer Programme in
2004. The mission will provide the best ever survey of the geomagnetic field and its temporal …

We study numerically an extensive set of dynamo models in rotating spherical shells,
varying all relevant control parameters by at least two orders of magnitude. Convection is …

Indoor environments present opportunities for a rich set of location-aware applications such
as navigation tools for humans and robots, interactive virtual games, resource discovery …

Knowledge of the Holocene evolution of Earth's magnetic field is important for
understanding geodynamo processes in the core, is necessary for studying long-term solar …

Even a cursory historical look at the development of geology reveals that the cooling of the
Earth has always been a central issue (Birch, 1965; Fourier, 1824; Holmes, 1915; Joly …
