Description:
The Vostok ground magnetometer station is located in Antarctica (-78.463 S, 106.826 E) and has been operated by the Arctic and Antarctic Research Institute of St. Petersburg since 1958. The analog data have been digitized for 1978 and 1979, and for 1983-1995. A 1-sec digital magnetometer was installed in 1996. The station is part of the former Soviet Union's scientific exploration of Antarctica, which started in 1957 during the International Geophysical Year (IGY). It is located near the center of the Antarctic ice sheet, about 3488 m above mean sea level, and about 1250 km from McMurdo and about 1500 km from Mirny on the coast. Vostok is located in the polar cap at a high magnetic latitude. In 1978, the magnetic field at the surface was about 60950 nT, with an inclination angle of -77.682 degrees, a declination angle of -11.835 degrees, and an apex magnetic location of (-83.30, 53.56). In 2001, the magnetic field at the surface was about 59470 nT, with an inclination angle of -76.807 degrees, a declination angle of -12.019 degrees, and an apex magnetic location of (-83.31, 55.11). The apex magetic location of -83.3 is very close to the corrected geomagnetic (cgm) location of -83.4 cgmlat used for Vostok.
