British (“Terra Nova”) Antarctic Expedition, 1910–1913: Terrestrial Magnetism

Abstract

BOTH of Captain Scott's Antarctic expeditions included observations of the earth's magnetism in their programme of scientific work, and the experience gained in the first was turned to good use in the second. The two magnetic observers were Dr. G. C. Simpson and Mr. C. S. Wright, to whom is due the credit for the fine work done at the base station. A noteworthy improvement was made by Dr. Simpson in the method of time-marking on the magnetograph sheets, which has since been adopted in some regula magnetic observatories. The magnetographs were in operation for nearly two years (February 1911 to November 1912); at the beginning of the second year Dr. Simpson was recalled to his official duties in India. Besides the continuous record of the three magnetic elements at Cape Evans, a considerable number of absolute measurements were made by the naval officers of the expedition, both in the “field ”(principally at Cape Adare) and at sea.
