Abstract. This paper examines the results of magnetotelluric soundings in the eastern Fennoscandian Shield, in the Murmansk region and the Republic of Karelia, conducted as part of the FENICS experiment series in 2014, 2019, and 2024. During this series of deep electromagnetic sounding experiments, a magnetotelluric data set has been obtained using modern measuring stations. Observation points have been presented in the form of three profiles. Based on polar diagrams, as well as the Swift and Barr parameters, natural field data in the AMT-MT range corresponding to the two-dimensional approximation have been selected. The study has revealed the general nature of the apparent resistivity and impedance phase curves. A two-dimensional inversion of the magnetotelluric soundings along three profiles has been performed using the MARE2DEM program. At that two zones of low specific resistance have been identified, which are consistent with previous magnetotelluric studies along the SVEKA profile in the area of the Ladoga electrical conductivity anomaly, as well as with the general nature of regional geological structures.
