Terra Nova Bay, Antarctica, Geomagnetic observatory, magnetic observations results, 2001-2002, 2002-2003

Abstract

These reports deal with activities undertaken at the Geomagnetic Observatory TNB in Antarctica during the austral summers 2001-2002 and 2002-2003. Since the Observatory was located very close to the Base, where the growing human activity gave rise to an increased artificial electromagnetic noise, during this campaign, the Observatory has been moved to a new site, called OASI, about 1 km away from the old site. In austral summer 2001-2002, geomagnetic absolute measurements have been performed at both sites, in order to evaluate possible spatial gradients between them. Conversely, the variometer measurements have been carried out only at the new site.
