Geomagnetic survey in East Ongul Island: estimation of the geomagnetic influence of the facilities installed by JARE-51 and JARE-52

During 2010 and 2011, some large facilities (e.g. a mechanical workshop, an atmospheric radar and a container yard) were constructed near the geomagnetic observation site at Syowa Station, Antarctica. Iron materials used in these facilities could potentially affect the geomagnetic field at the obser...

Description
Summary:During 2010 and 2011, some large facilities (e.g. a mechanical workshop, an atmospheric radar and a container yard) were constructed near the geomagnetic observation site at Syowa Station, Antarctica. Iron materials used in these facilities could potentially affect the geomagnetic field at the observation site. To evaluate the amount of artificial magnetic noise caused by the iron materials, we carried out magnetic surveys around Syowa Station before and after construction of the facilities. The results show that the iron materials generate a maximum of 1.0 nT of artificial noise at the geomagnetic observation site.
