Declination annual mean time series longer than 1 century provided by 24 geomagnetic
observatories worldwide, together with 5 Western European reconstructed declination series …

As a by-product of the construction of a new World Digital Magnetic Anomaly Map over
oceanic areas, we use an original approach based on the global forward modeling of …

This paper summarizes the results of the three previous papers in this series, which have
shown the presence of a pattern of magnetic anomalies, bilaterally symmetric about the crest …

Three new geomagnetic observatories have been established recently around the South
Atlantic geomagnetic Anomaly by GeoForschungsZentrum Potsdam (GFZ), Germany, in …

Analysis of palaeomagnetic data from the USSR, which Khramov and Sholpo have
separated into normal and reversed mean data, reveals that there is considerable and …

Secular variation of the Earth's main magnetic field is believed to originate in the Earth's
core.(The main field is operationally defined as comprising spherical harmonics of degree l⩽ …

Geomagnetic polarity reversal remains one of Nature's most enigmatic phenomena.
Dynamo theory admits solutions in pairs with reversed magnetic fields B and− B, but …

Variations of the Earth's magnetic field occur over an astonishingly wide time spectrum. Slow
changes with periods of a year to millions of years are of internal origin, sustained by fluid …

A two‐layer source model for marine magnetic anomalies can accommodate several
observations made on the shapes of anomalies in the Pacific and southeast Indian oceans …

Earth's magnetic field is unstable. Not only does it vary in intensity, but from time to time it
flips, with the poles reversing sign. Much of this behaviour remains a mystery, but a …
