Abstract

Mawson is an Australian National Antarctic Research Expedition base on the Antarctic mainland managed by the Australian Antarctic Division. Geomagnetic and seismological recording and processing equipment was maintained and calibrated by an observer provided by the Australian Geological Survey Organisation (AGSO) during 1994. Earthquake phase data was reported weekly to AGSO and to the National Earthquake Information Service (Boulder, Colorado) via email. Magnetic results were reported monthly to AGSO, and to the French Department de Geomanetisme et Paleomagnetism for use in the Oersted magnetic satellite project. Magnetic results indicate the secular variation of the field at Mawson was relatively unchanged over the year, with a three nanoteslas decrease in total intensity and a 5.5 minute increase in westerly declination. Magnetic data recorded at the Casey and Davis Antarctic bases was processed by the Mawson observer and indicated similar relative stability.
