Monitoring of Geomagnetic and Telluric Field Disturbances in the Russian Arctic

The influence of space factors on technological systems in the Arctic (power transmission lines, oil/gas pipelines) has become critically important. To examine depth these effects, an archive digital 1 min data from Soviet/Russian magnetic stations deployed along coast was created, starting 1983 to present. All various sources were converted daily files standard IAGA-2002 format and supplemented with quick-look magnetograms. Some are included already existing world field databases, but not all. Examples disturbances known excite intense geomagnetically induced currents power lines presented: irregular Pi3 pulsations perturbation events. database augmented global 3D model Earth’s conductivity structure. given example showed how combined usage geomagnetic enables one synthesize geoelectric response variations, assess distortions pipeline-soil potential. determine regions most susceptible hazard, a map normalized telluric fields created for uniform sinusoidally varying disturbance. This that largest electrotelluric potentials high resistivity (e.g., Kola Peninsula Ural Mountains). can be also useful support missions magnetosphere. is publicly available anonymous FTP site.
