Electromagnetic sounding from observations taken during the first International Polar Year

Measurements of magnetic field variations and natural earth currents, made at Kingua Fjord on Baffin Island, have been analyzed to obtain information on the electrical conductivity structure in the region. It is shown first, that these observations from 1882 form a remarkably consistent set, and secondly, that the station site displays the characateristics of a 'normal continental station' located on crystalline rock. A similar treatment of magnetic measurements made at Fort Rae yielded inconclusive results, probably because of the station's proximity to the auroral zone.-from Authors
