Investigating the Effect of Natural and Technogenic Atmospheric Disturbances of the Northern Hemisphere on the Electromagnetic Environment in the Antarctic (P-072)

摘要

This report results from a contract tasking National Academy of Sciences of the Ukraine as follows: The Project is aimed at studying the effect of high-energy natural and/or technogenic processes in the Northern hemisphere in the electromagnetic conditions of the Antarctic region. The observations are to be held at the Ukrainian 'Antarctic base (UAB) Academician Vemadsky' at 65 S, 64 W. The Antarctic is known to be the only continent where industrial production is prohibited and sizable electric power sources and consumers are absent. As a result, the electromagnetic 'climate' in the region is controlled mostly by processes in the lithosphere, atmosphere and magnetosphere. Besides, the Antarctic region is characterized by little, if any thunderstorm activity, that being the principal source of radio interference at low and middle latitudes at frequencies of fractions of one hertz to tens of megahertz. Hence, the natural conditions in the region are favorable for investigating the electromagnetic processes occurring in different parts of the world, such as the global thunderstorm activity, large-scale geomagnetic disturbances, the low frequency radiation from the lithosphere on the earthquake eve, and so forth.
