MTS Group News

  In the period from August 24 to September 08, the MTS Group consisting of 4 brigades carried out work on two profiles in the Kochkor district of Naryn region, Ukok-2 and Chon-Tuz. On the profile "Ukok-2", which is located south of Kochkorka village, team No. 1 and team No. 2 carried out work on magnetotelluric sounding (MTS) at 11 points. At 10 observation points, the duration of the MT field registration in the MTS mode was 16-18 hours, at the FT21 observation point in the DMTS mode, the duration of observations was about 300 hours.

  The work was carried out using Phoenix MTU-5 measuring complexes in the normal registration mode. The start of work was preceded by calibrations of recorders and sensors of MT stations. In all observation points, a control recording of at least 40 minutes was preceded to assess the level of interference and the settings of the parameters for recording the working record. The electrical components of MT field were measured using measuring devices with electric dipoles 50 m. long. The magnetic field components were measured using MTC-50 induction sensors. At all sounding points, the grounding of the dipoles was carried out using non-polarizing electrodes, the grounding of dipoles was carried out on the principle of “sensor to sensor” with previous years of observations. The orientations of measuring installations at these points completely repeated the previous deployments.

The monograph of coauthors from the RS RAS was awarded with the Diploma

In October 2021 Vladivostok hosted the 22nd Far Eastern Book Fair "Pechatny'y Dvor". About 300 books from 77 organizations were submitted for the Best Scientific Book competition. Published at the Institute of Marine Geology and Geophysics of the Far Eastern Branch of the Russian Academy of Sciences (with the recommendations of the RFBR reviewers) the monograph "Computational technologies in seismological studies (by the example of KNET, Northern Tien Shan)" by N.А. Sycheva, L.M. Bogomolov, S.I. Kuzikov received a Diploma in this nomination. Two co-authors of this monograph are employees of LGPS of Research Station RAS.

“Research and monitoring of geodynamically active zones” at EMS-2021

Director of the RS RAS Rybin A.K. took part as a convener of section 7 “Research and monitoring of geodynamically active zones” and a speaker at the VIII All-Russian School-Seminar on Electromagnetic Sounding named after M.N. Berdichevsky and L.L. Vanyan (EMS-2021). The school-seminar is traditionally the largest forum for all specialists dealing with electromagnetic methods of geophysics. The school-seminar was held from 4 to 9 October at the P.P. Shirshov Institute of Oceanology of the Russian Academy of Sciences (Moscow). The scientific program included seven scientific sessions covering the entire spectrum of academic and applied electromagnetic research and a series of review reports by leading scientists on the most pressing topics of modern geoelectrics. The format of the school was mixed - the broadcast was conducted on the EMS-2021 website. Employees of the Laboratory of Deep Magnetotelluric Soundings of the RS RAS made reports in offline and online formats.

Geodynamic processes occurring in active regions of the planet are manifested in various geophysical fields. The task of monitoring the processes of cracking is urgent, and the successful separation of the magnetotelluric field into endogenous and exogenous components allows us to detect the moment of activation of cracking. The solution of the problem of locating the activated volume is possible with the help of a three-component gradient installation for recording the seismoacoustic field near the day surface.

An article entitled «VOLUMETRIC AND SPATIAL SEGMENTATION OF THE TIEN SHAN LITHOSPHERE ACCORDING TO GEOPHYSICAL DATA» by the research team of the authors of the Laboratory of Deep Magnetotelluric Research of the RS RAS (Rybin A.K., Bataleva E.A., Nepeina K.S., Matyukov V.E.) is published in the scientific journal «Geodynamics & Tectonophysics», indexed by the international Scopus database of the third quartile (Q3).

The geological and geophysical materials on the deep structure of the crust and upper mantle of the Central Tien Shan were collected and analyzed under Project 16-17-10059 supported by the Russian Science Foundation. For the comprehensive analysis of geological and geophysical information, the data on the Northern Tien Shan were prepared under the state assignment of the Research Station RAS in Bishkek for 2019–2021, which was funded by the RF Ministry of Science and Higher Education (project АААА-А19-119020190063-2).

Regional GNSS measurements in Kyrgyzstan in 2021.

   This year, employees of GPS laboratory (RS RAS) conducted routine field measurements of the Kyrgyz GPS network sites based on the Global Navigation Satellite Systems (GNSS) method. Annual repeated surveys of the same GPS sites on the study area allow to fix the high-precision position of the site at the measurement time and to track the multi-year rate of its displacement to solve fundamental geodynamic problems, as well as to assess the danger of the population and vital objects.

   From May to September 2021, two campaigns (KGS21a from 25.05.2021 to 25.06.2021; KGS21b from 17.08.2021 to 15.09.2021) were carried out for measure regional sites on the territory of Kyrgyzstan (Fig.1).
