| Summary: | During the 1986-87 austral summer a geomagnetic observatory was installed at Terra Nova Bay. During the firstyears both geomagnetic field time variation monitoring and absolute measurements were carried out only duringsummer. Since 1991 variometer measurements are automatically performed throughout the year, while absolutemeasurements are still performed only during summer. In spite of this, interesting observations were obtainedduring the life (quite long for Antarctica) of the geomagnetic observatory. In particular, this paper brieflypresents some of the most important results: studies on secular variation, daily variation (and its dependencefrom solar cycle and seasons) and geomagnetic higher frequency variations, such as geomagnetic pulsations. |
