The modeling of magnetotelluric field in the region of the islands Sredny and Pezhostrov of the White Sea.
Saltsberg A.V.

In July 2011 were carried out magnetotelluric sounding on two islands of the White Sea: Sredny and Pezhostrov. Recording was taken by station GI-MTS-1. For similar regions with limited opportunities for sounding especially actual the problem of constructing geoelectric profile by minimal source data. 
In the course of this work was performed processing of time series obtained from the soundings and made a one-dimensional inversion program MLAR described in [2]. Using results of the inversion and data available for this area was built preliminary model of researched region.
For the resulting model was solved 3D- direct task by program Mackie. On map of this area was selected individual points where possible to carry out soundings (i.e. island and adjacent parts of mainland), made 1D-inversion for impedance values obtained in the solution of 3D-direct task and compared with the local cut of model in these points. Shown that the results of this approach to interpreting in condition of limited information can be used as a starting model for further researches.
