Analysis of the physical parameters of the sedimentary cover rocks of the northwestern part of DDD in connection with its oil and gas bearing capacity

Density and volume magnetic susceptibility were studied from 8 boreholes drilled in north-western part of Dnipro-Donets Depression. The variations of these parameters were analyzed for the major rock types found in each of the wells. Magnetic susceptibility investigations of dry and fluidsaturated samples in heating process were pursued

Natural and technogenic components of megalopolis magnetic field

Magnetic storm influence becomes more and more interesting for people. In this article we describe measurable magnetic field data from different megalopolis regions and from the underground passenger transport on the Kyiv city example. There were five observation points evenly situated among the city, and one metro route with direct and reverse direction movement. Collected information shows general situation with magnetic noise in populous cities. Smartphones are very popular today so we have used one of them as a budget magnetometer in our research. 

EARTH'S MAGNETIC FIELD DYNAMICS: SPACE WEATHER AND SOLAR CYCLE EFFECT EXHIBITING

According to the “Odessa” and “Kiev” observatories total vector magnetic field variations data for 2008-2010 period, dynamics of the space weather manifestations were considered. Wavelet analysis application made the determination of structure changing in circadian period possible. The features of displaying 12, 8 and 6 hour periods are shown. The nature of their correlation and modulation in solar and geomagnetic activity changing is seen. Two stations changes differences that can result from the latitudinal dependence are examined. The existence of “Odessa” magnetic anomaly located on land and at sea is reviewedAccording to the “Odessa” and “Kiev” observatories total vector magnetic field variations data for 2008-2010 period, dynamics of the space weather manifestations were considered.

GEOMAGNETIC FIELD OF UKRAINE: ESTIMATION OF INTERNAL AND EXTERNAL SOURCES CONTRIBUTION

This article is considering some aspects of differentiation between internal and external sources of the Earth's magnetic field; it estimates also thecontribution of different sources into total field as well as its variations. The surveys results of ukrainian magnetic observatories were used to fulfil the task
