    Towards the Opening of a Magnetic Observatory at Dome C (Antarctica) (2008)
    Details
    Publication Date: 2017-04-04
    Description: The opening of a new magnetic observatory is one of the activities aimed at by the creation of a scientific base at DomeC, Antarctica (lat. 75° 06’S, long. 123° 21’E, elev. 3200m). There are many reasons supporting this objective: all Antarctic magnetic observatories providing absolute values are located along the shore and are therefore subject to coast effects and crustal field contamination. DomeC and Vostok will be so far the sole observatories free from these effects. On one hand, high latitude absolute observatories are very useful to global or regional modeling based upon satellite data, because, at high latitudes, only total field measurements can be used due to the strong influence of field aligned currents. On the other hand, the availability of magnetic data from the well distributed observatories of Terra Nova Bay (TNB), Scott Base (SBA), Dumont d’Urville (DRV), Casey (CSY) and Vostok (VOS) will provide strong support to auroral and polar cap ionosphere studies as well as asymmetry analyses between Northern and Southern hemispheres. This paper summarizes the results gathered during three summer campaigns, in 1999-2000, 2001 and 2003-2004.

    GEOSTAR deep seafloor missions: magnetic data analysis and 1D geoelectric structure underneath the Southern Tyrrhenian Sea (2008)
    INGV
    Details
    Publication Date: 2017-04-04
    Description: From 2000 to 2005 two exploring geophysical missions were undertaken in the Tyrrhenian deep seafloor at depths between around -2000 and -3000 m in the framework of the European-funded GEOSTAR Projects. The considered missions in this work are GEOSTAR-2 and ORIONGEOSTAR-3 with the main scientific objective of investigating the deep-sea by means of an automatic multiparameter benthic observatory station working continuously from around 5 to 12 months each time. During the two GEOSTAR deep seafloor missions, scalar and vector magnetometers acquired useful magnetic data both to improve global and regional geomagnetic reference models and to infer specific geoelectric information about the two sites of magnetic measurements by means of a forward modelling.

    Twenty years of geomagnetic field observations at Mario Zucchelli Station (Antarctica) (2010)
    INGV
    Details
    Publication Date: 2017-04-04
    Description: During the 1986-87 austral summer a geomagnetic observatory was installed at Terra Nova Bay. During the first years both geomagnetic field time variation monitoring and absolute measurements were carried out only during summer. Since 1991 variometer measurements are automatically performed throughout the year, while absolute measurements are still performed only during summer. In spite of this, interesting observations were obtained during the life (quite long for Antarctica) of the geomagnetic observatory. In particular, this paper briefly presents some of the most important results: studies on secular variation, daily variation (and its dependence from solar cycle and seasons) and geomagnetic higher frequency variations, such as geomagnetic pulsations.

    Description: These reports deal with activities undertaken at the Geomagnetic Observatory TNB in Antarctica during the austral summers 2001-2002 and 2002-2003. Since the Observatory was located very close to the Base, where the growing human activity gave rise to an increased artificial electromagnetic noise, during this campaign, the Observatory has been moved to a new site, called OASI, about 1 km away from the old site. In austral summer 2001-2002, geomagnetic absolute measurements have been performed at both sites, in order to evaluate possible spatial gradients between them. Conversely, the variometer measurements have been carried out only at the new site.

    Description: The Earth is immersed in a planetary magnetic field. The field is generated in the Earth’s core and can be measured at its surface. It shows mainly a typical dipolar profile with the dipole axis roughly parallel to the Earth’s rotation axis (tilting about 12°). At low latitudes the field reaches its minimum, while its maximum intensity is observable in polar regions, reaching there almost three times its equatorial value. The region around the Earth where the geomagnetic field extends is known as the Earth’s magnetosphere. This region contains a very low density gas of electrically charged particles and is the space around the Earth where many electric and magnetic phenomena happen.
