An assessment of the near-surface accuracy of the international geomagnetic reference field 1980 model of the main geomagnetic field An assessment of the near-surface accuracy of the international geomagnetic reference field 1980 model of the main geomagnetic field
The new International Geomagnetic Reference Field (IGRF) model of the main geomagnetic field for 1980 is based heavily on measurements from the MAGSAT satellite survey. Assessment of the accuracy of the new model, as a description of the main field near the Earth's surface, is important because the accuracy of models derived from satellite data can be adversely affected by the magnetic...

More on the alleged 1970 geomagnetic jerk More on the alleged 1970 geomagnetic jerk
French and United Kingdom workers have published reports describing a sudden change in the secular acceleration, called an impulse or a jerk, which took place around 1970. They claim that this change took place in a period of a year or two and that the sources of the alleged jerk are internal. An earlier paper by this author questioned their method of analysis pointing out that their...

How the geomagnetic field vector reverses polarity How the geomagnetic field vector reverses polarity
A highly detailed record of both the direction and intensity of the Earth's magnetic field as it reverses has been obtained from a Miocene volcanic sequence. The transitional field is low in intensity and is typically non-axisymmetric. Geomagnetic impulses corresponding to astonishingly high rates of change of the field sometimes occur, suggesting that liquid velocity within the Earth's...
