Maud expedition, 1918-1925.
Maud expedition records, 1918-1925.
This collection contains geophysical data, computations, reports, and photographs made during the two Arctic voyages of the ship "Maud" between 1918 and 1925. Roald Amundsen, polar explorer, commanded the ship and H.U. Sverdrup was in charge of the scientific experiments and observations. The Carnegie Institution's Department of Terrestrial Magnetism provided instruments and computational aids, and published the expedition's scientific results.
The wooden vessel "Maud" departed Norway in July, 1918 under the command of polar explorer Roald Amundsen, with the aim of lodging in the ice pack above the Bering Strait and drifting across the Arctic Ocean. The "Maud" was well equipped with scientific apparatus for making meteorological, geophysical, and oceanographic observations, including geomagnetic instruments and computational aids furnished by the Carnegie Institutions Department of Terrestrial Magnetism. Meteorologist/oceanographer H. U. Sverdrup was in charge of the expeditions scientific work. During the next three winters, with the vessel icebound off the Siberian coast, important series of geomagnetic and auroral measurements were made, but the goal of drifting to the North Pole was unrealized. In August, 1921 the "Maud" reached Seattle for overhauling and preparations were made for another attempt. During the second phase of the expedition (1922-1925), the "Maud" was locked in the ice for more than two years and drifted northwest as far as the New Siberian Islands. Once released, the vessel headed eastward under its own power, but the expedition was forced to spend one more winter icebound during 1924-25. Extensive geomagnetic and atmospheric electricity data were collected during the drift and at winter quarters near Bear Island. The "Maud" finally returned to Nome, Alaska in August, 1925. The geophysical results of the expedition, prepared by Sverdrup, were published by the Carnegie Institution in 1927.
