Magnetic Observatory at Mario Zucchelli Station


Latitude: 74° 42’ S, Longitude: 164° 6’ E (Antarctica)

In the framework of the Italian National Program for scientific research in Antarctica (PNRA), during the austral summer of 1987 it has been installed at Terra Nova Bay the first Italian magnetic observatory on Antarctic land. Though the base is inhabited only during the summer period, since 1992 the observatory has been operating also during winter in automatic mode. The observatory consists of four amagnetic buildings for instrumentation, absolute measurements pillar, services and a room for acquisition, respectively.

Instruments

The observatory is equipped with two systems, both consisting of an Overhouser magnetometer to measure total intensity F and a vector magnetometer to measure the three components of the field in the reference frame of H, D, Z, materialized by three orthogonal sensors. Magnetometers are oriented in the magnetic meridian.


Geographic Co-ordinate:

Geomagnetic Co-ordinate:

74° 42’ S   164° 6’ E

80° S        307° 24’ E

Corrected geomagnetic coordinates are estimated for the epoch 2007.0 by the routine available at the NASA CCMD website.
