In the period from July 16 to August 6, the MTS group consisting of 2 teams carried out work on the Ukok-2 profile, which is located south of the Kochkorka in the Kochkor district of the Naryn region. The works was carried out on magnetotelluric sounding (MTS) at 11 points. At 10 observation points, the duration of MT-field registration in the MTS mode was 36-43 hours, at the FT21 observation point in the DMTS mode, the registration was performed in the form of two registration sessions, the duration of each was about 240 hours.

The works was carried out using Phoenix MTU-5 measuring complexes in the standard recording mode. The start of the work was preceded by calibrations of the recorders and sensors of the MT stations. At all observation points, a control recording lasting at least 40 minutes was made to assess the level of interference and adjust the recording parameters of the working record.

The MT field electric components were measured using measuring installations with 50 m long electric dipoles. The magnetic field components were measured using MTS-50 induction sensors. At all sounding points, dipole grounding was performed using non-polarizing electrodes; dipole grounding was performed according to the “sensor to sensor” principle from previous years of observations. The orientations of the measuring installations at these points completely repeated the previous deployments.
