Magnetic observations at Georg von Neumayer station, Antarctica

Abstract

In 1981 a German permanent wintering-over base — the Georg von Neumayer station (GVN) — was established. Since then, geophysical and meteorological parameters have been recorded continuously. Although it seems that an antarctic ice shelf is not suited as base for a permanent geophysical observatory, it could be shown, that the continous registration of the geomagnetic field vector at GVN is very useful for studies of ionospheric and magnetospheric phenomena. In order to separate true time variations of the geomagnetic data from local disturbances at first many careful statistical studies of the measured time series were necessary. For instance contaminating swell-effects could be detected, and it is important to distinguish these from geomagnetic pulsations.
