The Earth's internal magnetic field varies on timescales of months to billions of years. The
field is generated by convection in the liquid outer core, which in turn is influenced by the …

After many years spent by paleomagnetists studying the directional behavior of the Earth's
magnetic field at all possible timescales, detailed measurements of field intensity are now …

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 …

Paleomagnetic data are useful in many applications in Earth Science from determining
paleocurrent directions to analyzing the long-term behavior of the geomagnetic field. In this …

We have reviewed paleomagnetic data available for the Eurasian, African, North American
and Indian plates over the last 200 Ma. Selection criteria are those generally accepted, with …

In 1995, two groups [Kageyama et al., 1995; Glatzmaier and Roberts, 1995a, 1995b]
reported results of numerical integrations of fully three‐dimensional, fully nonlinear …

It is now widely thought that geomagnetic polarity reversals occur spontaneously as a result
of normal dynamo action rather than being externally triggered. If this is the case, then it may …

The magnetic field of the Earth is by far the best documented magnetic field of all known
planets. Considerable progress has been made in our understanding of its characteristics …

Recent numerical simulations have yielded the most efficient geodynamo, having the largest
dipole intensity when reversal frequency is low. Reliable paleointensity data are limited but …

Knowledge of palaeointensity variation is required for determining the full vector variation of
the geomagnetic field as a function of geological time. This provides essential constraints for …
