Name: Leningrad Branch of the Institute of Terrestrial Magnetism, Ionosphere, 
and Radio-Wave Propagation 
(Leningradskoye otdeleniye instituta zemmogo magnetizma, ionosfery 
i rasprostraneniya radiovoln) 
Address: Leningrad 
Director: V. I. Pochtarev (1961) 
Deputy Director: -- 
Administrative Affiliation: Academy of Sciences, U.S.S.R. (1961) 
Selected Staff Members: -- 
Description: 
In July of 1961, this institute sent an expedition to Kamchatka 
to study geomagnetic changes prompted by volcanic action. In 1959, the 
Institute compiled a world magnetic-declination map based on data obtained 
by expeditions on the Soviet nonmagnetic ship, Zarya. This ship not only 
collects data on terrestrial magnetism, but also on the ionosphere and cosmic 
rays. It publishes a Trudy, and Kosmicheskiye Dannyye (Cosmic Data), monthly.
