Geomagnetic observations have been made at both bases, in cooperation with the Australian Geological Survey Organisation (AGSO), since early 1970s to provide information on the secular variation of the magnetic field. The magnetic observations and recording carried out by the ANARE expeditioners during 1994 were processed by AGSO's observer at Mawson. Results indicate the secular variation of the field at Casey was relatively unchanged over the year, while the field at Davis has decreased by some 30 nT in total field strength, and moved westerly by some 8 minutes in declination.
