| Zusammenfassung |
| In July of 1931, on the eve of International Polar Year II, an Arctic flight
of the Graf Zeppelin rigid airship was organized. This flight was a
realization of the idea of F. Nansen, who advocated the use of airships for
the scientific exploration of the Arctic territories, which were poorly
studied and hardly accessible at that time. The route of the airship flight
was Berlin – Leningrad – Arkhangelsk – Franz Josef Land – Severnaya
Zemlya – the Taimyr Peninsula – Novaya Zemlya – Arkhangelsk – Berlin. One
of scientific goals of the expedition was to measure the H and D geomagnetic
field components. Actually, the first aeromagnetic survey was carried out in
the Arctic during the flight. After the expedition, only preliminary results
of the geomagnetic measurements, in which an anomalous behavior of magnetic
declination in the high-latitude part of the route was noted, were published.
Our paper is concerned with the first aeromagnetic measurements in the
Arctic and their analysis based on archival and modern data on the magnetic
field in the Barents and Kara sea regions. It is shown that the magnetic field
along the flight route had a complicated structure, which was not reflected
in the magnetic charts of those times. The flight was very important for
future development of aero- and ground-based magnetic surveys in the Arctic,
showing new methods in such surveys. |
