Shannon information of the geomagnetic field for the past 7000 years [PDF]
Nonlinear Processes in Geophysics, 2010 The present behaviour of the geomagnetic field as expressed by the International Geomagnetic Reference Field (IGRF) deserves special attention when compared with that shown over the past few thousands of years by two paleomagnetic/archeomagnetic models ...

The model of the geomagnetic non-dipole field.
Journal of geomagnetism and geoelectricity, 1983 Yukutake's model separates the geomagnetic field into drifting and standing parts, not only fits well to the observed field for the past several hundred years, but also emphasizig the regularities of the westward drift of the geomagnetic non-dipole field. However, there are still some problems to be reinvestigated:a) In Yukutake's model the geomagnetic

April 2000 geomagnetic storm: Ionospheric drivers of large geomagnetically induced currents [PDF]
, 2003 International audienceGeomagnetically induced currents (GIC) flowing in technological systems on the ground are a direct manifestation of space weather. Due to the proximity of very dynamic ionospheric current systems, GIC are of special interest at high

Archaeological Prospection, EarlyView.ABSTRACT This study presents a multi‐method non‐invasive investigation of an approximately 4‐ha area associated with the long‐occupied coastal settlement of Rocavecchia (Apulia, southern Italy), situated between the prehistoric fortified peninsula and the Hellenistic‐Messapian walls.

Katz Fractal Dimension of Geoelectric Field during Severe Geomagnetic Storms
Entropy, 2021 We are concerned with the time series resulting from the computed local horizontal geoelectric field, obtained with the aid of a 1-D layered Earth model based on local geomagnetic field measurements, for the full solar magnetic cycle of 1996–2019 ...

The International Geomagnetic Reference Field [PDF]
, 2011 The International Geomagnetic Reference Field (IGRF) is an internationally agreed and widely used mathematical model of the Earth’s magnetic field of internal origin. We describe its inception in the 1960s and how it has developed since. We also describe

Journal of Quaternary Science, EarlyView.Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

Correlation‐based modeling and separation of geomagnetic field components [PDF]
Journal of Geophysical Research: Solid Earth, 2016 AbstractWe introduce a technique for the modeling and separation of geomagnetic field components that is based on an analysis of their correlation structures alone. The inversion is based on a Bayesian formulation, which allows the computation of uncertainties.

Oscillating magnetic field disrupts magnetic orientation in Zebra finches, Taeniopygia guttata
, 2009 Background Zebra finches can be trained to use the geomagnetic field as a directional cue for short distance orientation. The physical mechanisms underlying the primary processes of magnetoreception are, however, largely unknown.
