Magnetic phenomena in the region of the south magnetic pole

Abstract

Magnetographs were in operation at Cape Evans, the base station of the British (Terra Nova) Antarctic Expedition (77° 38' S., 166° 24' E.), during 1911 and 1912. A second set was in operation at the base station of the Australasian Antarctic Expedition in Adelie Land (67° 0' S., 140° 40' E.) during 1912 and 1913. There were synchronous records for seven months, April to October, 1912. Having been charged with the discussion of both sets of magnetic curves, a unique opportunity was afforded me of studying magnetic phenomena occurring near the south magnetic pole, which is intermediate in position to the two stations. With the approval of Sir Douglas Mawson and of the Committee for the Publication of the Scientific Reports of the British Antarctic (Terra Nova) Expedition, I propose in the present paper to give some of the prominent results of the intercomparison.
