It is primarily dipolar (i.e., it has two poles, the north and south magnetic poles) on Earth’s surface. Away from the surface the dipole becomes distorted. The field is variable, changing continuously, and its poles migrate over time.
Three different excursional paleomagnetic directions were reported from eight volcanoes of the Auckland volcanic field in New Zealand: north-down (ND) directions obtained from five volcanoes, Excursions and secular variation of the Brunhes epoch geomagnetic field in the Indian Ocean region, J.

K-Ar age determinations were made on two monogenetic volcanoes in the Auckland volcanic field, New Zealand, which have recorded the Auckland geomagnetic excursions. For the Wiri volcano with the north-down intermediate paleomagnetic direction, five samples gave a weighted mean age of 27 ± 5 (1σ) ka. For the Hampton Park volcano with the Cited by: Of entered MS prevalence data, 19 data were from Australasia, including Australia and New Zealand, 77 from Europe and 15 data were from North America.

I am very pleased that my book The Geomagnetic Field and Life is being published in English in the United States. Thanks to the initiative of Plenum Press, a publishing hause that is widely known in all countries, I have a great new opportunity to make direct contact with friends throughout the world.3/5(1).

These models include the magnetic field contributions from the Earth's crust. These models are suitable for applications where higher navigational accuracy is required.
The EMM is an epoch release of the Enhanced Magnetic Model, intended to. Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the Earth's outer core:.

Hence the age data provide additional information on geomagnetic polarity epochs and reversals of the earth's magnetic field. Together with previously published results, the new K‐Ar dates strongly suggest that a change from normal to reversed polarity occurred ± m.y. ago. Geotherraics (x97o) - SPECIAL ISSUE 2 U.

Unlike a classic bar magnet, the matter governing Earth's magnetic field moves around. Geophysicists are pretty sure that the reason Earth has a magnetic field is because its solid iron core is surrounded by a fluid ocean of hot, liquid metal. The flow of liquid iron in Earth's core creates electric currents, which in turn creates the magnetic.Virtual geomagnetic pole (VGP) groups for the New Zealand and French records early in the excursion are compatible with a dipole-dominated field that .Summary.
Using the results of spherical harmonic analyses of the geomagnetic field for some fourteen different epochs, including Gauss' first analysis for epochand the Erman-Petersen analysis for epochthe strength and axes of geomagnetic multipoles have been computed.
In particular, a dipole from the three first order spherical harmonic coefficients, a quadrupole Cited by:
