Low-frequency (0.7-7.4 mHz) geomagnetic field fluctuations at high latitude:frequency dependence of the polarization pattern
Geomagnetic pulsation MHD waves and instabilities wave polarizations Antartica
2015/9/28
A statistical analysis of the polarization pattern of low-frequency geomagnetic field fluctuations (0.7-7.4 mHz) covering the entire 24-h interval was performed at the Antarctic station Terra Nova Bay...
Local time behaviour of low frequency geomagnetic field fluctuation power at low latitude
Geomagnetic pulsation MHD waves and instabilities
2015/9/28
In this paper we present a statistical study of the local time behaviour of low frequency (0.7-4.0 mHz) geomagnetic field fluctuation power at a low latitude station (corrected geomagnetic latitude 36...
Time intermittency and spectral features of the geomagnetic field
nonlinear processes in geophysics geomagneticfield Earth's core fluid dynamics turbulence
2015/9/11
In the field of geomagnetism a number of studies have been devoted to the investigation of turbulence and intermittency in the outer core fluid motions. Here, in order to obtain information on such ph...
Low frequency geomagnetic field fluctuations at cap and low latitude during October 29-31,2003
magnetospheric ULF waves sun-earth interaction polar cap
2015/9/2
On October-November 2003 complex interplanetary structures, originated by a series of solar eruptions, hit the Earth, triggering violent Sun-Earth connection events. In this paper we analyze the low f...

Geomagnetic repeat station data crustal bias
2015/8/26
Geomagnetic repeat station surveys with local variometers for improved data reductions have been carried out in Germany for about ten years. For nearly the same time interval the satellites Ørste...

2015/8/26
The status of the Croatian Geomagnetic Repeat Stations Network (CGRSN) and Croatian Geomagnetic Network for Field Mapping (CGNFM), completed in 2010, was described. Standard and new survey practices a...
Repeat-station surveys: implications from chaos and ergodicity of the recent geomagnetic field
Magnetic repeat stations Chaos Ergodicity
2015/8/18
The present geomagnetic field is chaotic and ergodic: chaotic because it can no longer be predicted beyond around 6 years; and ergodic in the sense that time averages correspond to phase-space average...
