Abstract
Measurements of the magnetic component of the Schumann resonance in the frequency range 6-14 Hz were performed
at high latitude location (TNB Antarctica; geographic coordinates: 74.7°S, 164.1°E; geomagnetic coordinates:
80.0°S, 307.7°E; LT=UT+13; MLT=UT–8; altitude=28 m a.s.l.), during the two years 1996-1997. TNB
is a particularly important observation site located in a region characterised by a high electromagnetic activity in the
ELF and VLF bands. Moreover its remote location in Antarctica provides the important advantage that electromagnetic
background noise is not corrupted by anthropogenic noise and that the continental lightning activity is very low.
The combination of low additional anthropogenic electromagnetic radiation and low atmospheric noise in this area
allows detailed investigations into wave generation and amplification in the polar ionosphere and magnetosphere not
possible anywhere else in the world. This paper reports the study of the magnetic power of the 8 Hz Schumann resonance
mode. For both the years considered diurnal and long-term seasonal variations were observed.
