Results of the Magnetic Expedition to Mongolia in 1913
Abstract Generated abstract
This report presents magnetic observations from the 1913 expedition to Mongolia, listing geographic coordinates, magnetic declination, and the horizontal component of the magnetic field for stations along a route from the Transbaikal region across Mongolia to the Altai and Barnaul area. The measurements are tabulated and reduced to the epoch 1913.7, providing a standardized dataset for comparing regional magnetic variation. An addendum includes two additional determinations made in Eastern Mongolia in 1914 by I. A. Molchanov, reduced to the epoch 1914.5.
