  From July 19 to August 08 2022, the MTS group consisting of 4 teams performed work on two profiles in the Kochkor district of the Naryn region, Ukok-2 and Chon-Tuz. On the profile "Ukok-2", which is located south of the village of Kochkorka, teams No. 1, No. 2 and No. 3 carried out work on magnetotelluric sounding (MTS) at 11 points. At 10 observation points, the duration of the registration of the MT field in the MTS mode was 60-65 hours, at the observation point FT21 in the deep MTS mode, the registration was performed in the form of two registration sessions, and the duration of each was about 240 hours. The work was carried out using Phoenix MTU-5 and MTU-5A measuring systems in the normal recording mode. At the same time, seismic fields were recorded at observation point FT21 using the installed gradient seismic installation.

  Before the start of the main work on the profile "Ukok-2", in the area of ​​the observation point FT15 (MTS), teams No. 3 and No. 4, using the multi-electrode station "Skala 48", carried out work on 24-hour monitoring in the amount of 37 blocks of measurements, duration every 40 minutes by methods of electric tomography and induced polarization, type of array configuration "Schlumberger".

  Chon-Tuz profile, which is located south of the village of Tuz, teams No. 3 and No. 4 performed work using the methods of electrical tomography and induced polarization using the “Skala 48” multi-electrode station to extend the profile worked out with the help of this station in 2021. Data registration was performed by two types of array configurations: "Schlumberger" and "Wenner". The station was operated using two multi-electrode cables, the length of each connecting cable is 120 meters, the installation of electrodes was carried out in increments of 5 meters, the total number of electrodes when deploying two connecting cables is 48 pieces. Taking into account the extended section, the length of the developed profile approximately increased to 4080 meters, the registration was carried out at 5 basic observation points.

  Upon completion of the main work on the profile, in the area of ​​the FT18 (MTS) point, 36-hour monitoring was performed in the amount of 51 measurement blocks, each lasting 40 minutes using the methods of electrical tomography and induced polarization, type of the “Schlumberger” array configuration.
