In the period from July 04 to July 25 MTZ group consisting of 3 brigades carried out works on the profile "Ukok-2", which is located to the south of Kochkorka village in Kochkor district of Naryn oblast. The works on magnetotelluric sounding (MTZ) were carried out at 11 points. At 10 observation points the duration of MT field registration in the MTZ mode was 36-43 hours, at the observation point FT21 in the GMTZ mode, the registration was carried out in the form of two sessions of registration, duration of each was about 240 hours.

The work was carried out using the Phoenix MTU-5 and MTU-5A measurement complexes in the normal registration mode. The beginning of the work was preceded by calibrations of the recorders and sensors of MT stations. At all observation sites, a control recording of at least 40 minutes was preceded by a control recording to assess the level of interference and settings of registration parameters. The electric components of MT field were measured using measuring installations with electric dipoles of 50 m length. The magnetic field components were measured using MTS-50 induction sensors. At all sounding points the grounding of dipoles was carried out with the help of non-polarizing electrodes, grounding of dipoles was carried out according to the principle "sensor to sensor" with the previous years of observations. The orientations of the measurement setups at these stations were fully repeated with the previous deployments.
