Aeromagnetic Survey in the Vicinity of Prince Olav Coast, Antarctica
The aeromagnetic surveys in the vicinity of Lutzow-Holm Bay, Antarctica, were carried out by the 8th-llth Japanese Antarctic Research Expedition (JARE) during the period from January 1967 to January 1970, for the purpose of investigating the features of the geomagnetic field in the polar region.
