Estimation of the mantle conductivity of the southwestern part of the East European Platform
Геофизический журнал, 2015 Geoelectric structure of the mantle at the depth of 100—1000 km is determined through joint interpretation of magnetotelluric sounding in 115 sites in the territory of southwestern part of the East European Platform and geomagnetic induction sounding ...

Alexandria Engineering Journal, 2023 The geoelectric fields induced during geomagnetic disturbances (GMD) may affect the normal operation of technological systems at the Earth’s surface. The non-uniform Earth conductivity structure, especially large lateral conductivity contrasts, can lead ...

The use of the vertical component in geomagnetic depth sounding [PDF]
Geophysical Journal International, 1977 Summary. In previous papers, we showed how we found it possible to define the anomalous field by means of its horizontal components defined as the difference between the field recorded at a reference station and that recorded at stations on the anomaly. In the present short note, we extend this definition to the vertical component.

Methods of magneto-variation sounding of the Earth's mantle within the range of periods 10 4 -10 5 s
Геофизический журнал, 2010 Impedances of new generalized magnetovariation sounding method are estimated for the period range 10 4 -10 5 s using geomagnetic data of five east European observatories.

Space Weather, 2021 In the United Kingdom, geomagnetically induced currents (GICs) are calculated from thin‐sheet electrical conductivity models. In the absence of conductivity models, time derivatives of magnetic fields are sometimes used as proxies for GIC‐related ...

Donbas conductivity anomaly in the Karpinsky Swell
Геофизический журнал, 2023 Donbas Foldbelt (DF) and Karpinsky Swell (KS) are contiguous parts of a system of elongated sedimentary basins forming lineament from Poland through Pripyat Trough in Belarus, the Dnieper-Donets Basin (DDB) and DF in Ukraine, KS in Russia, across the ...

Donbas geoelectrical structure
Геофизический журнал, 2022 The Donbas was formed as the result of Late Devonian rifting of the East European craton. During the Carboniferous, the subsidence of the basin and sedimentation were at their maximum, and a 15-kilometer stratum of Carboniferous deposits formed in the ...

Observations of lower hybrid cavities in the inner magnetosphere by the Cluster and Viking satellites [PDF]
Annales Geophysicae, 2004 Observations by the Viking and Cluster satellites at altitudes up to 35000km show that Lower Hybrid Cavities (LHCs) are common in the inner magnetosphere. LHCs are density depletions filled with waves in the lower hybrid frequency range.
