Аннотация (русский):
A stratospheric balloon flight at 30km altitude measured the geomagnetic field intensity along a 6000km track extending from Kamchatka to near the Ural Mountains. When the CM model was used to remove the main and external fields from the observed data, magnetic anomalies of several 100nT amplitude and 250 to 750km wavelength are observed. In the eastern part of the track these anomalies appear to be due to the bodies of up to 5km depth and magnetizations of 0.12SI 0.01cgs.
