Preliminary report of electromagnetic soundings on East Ongul Island, Antarctica
Observations of the telluric field were carried out at Syowa Station (69°S, 39°35'E) in Lutzow Holm Bay, East Antarctica from May 22, 1995 to January 31, 1996. Telluric fields at Syowa Station have strong anisotropy which varies with frequency. Major axis of electrical variations at high freque...
