The influence of frequency dispersion of conductivity (induced polarization) of rocks on the results of electromagnetic (EM) sounding was studied on the basis of calculation of electric field of verti...
The temporal and spatial variations of low frequency geomagnetic pulsations at polar cusp and cap latitudes
Geomagnetic pulsations Antartica
2015/10/8
Geomagnetic field measurements at two Antarctic stations are compared during two weeks in the local summer (January 1-15, 1992). Low frequency (0.6-6 mHz) pulsations are observed at each station near ...
