Results of the Yenisei Magnetic Expedition of 1912
Abstract Generated abstract
This paper reports the results of the 1912 Yenisei magnetic expedition, presenting geomagnetic observations from a sequence of stations along the Yenisei region. The authors tabulate each station’s latitude and Greenwich longitude together with magnetic declination, horizontal component, and inclination, reduced to the epoch 1912.8. The dataset documents systematic geographic variation in the measured magnetic elements from Ust-Kan to Dudinka, while distinguishing interpolated values and measurements considered doubtful.
