“…Выполнены эксперименты по комплексной регистрации волнового поля вибратора ЦВО-100 на суше и на льду Байкала с использованием сейсмометров и донной станции и в воде с помощью гидрофонов (ИФЗ РАН, ИВМиМГ СО РАН, ГИН СО РАН, ИЗК СО РАН 2020, 2021 гг.). На полученных сейсмограммах выделяются сейсмические волны, проходящие по кристаллическому фундаменту, по осадочным отложениям, а также в водной толще Байкала [Sobisevich et al, 2021]. Зарегистрированы акустические волны, генерируемые при работе вибратора и распространяющиеся в приповерхностном звуковом канале надо льдом Байкала на расстояние 85 км.…”

The article provides an overview of vibroseismic studies carried out in the Baikal rift zone using LargeScale Research Facilities – a powerful CVO-100 seismic vibrator, installed at the South Baikal geodynamic test site SB RAS. Research is carried out according to several methods focused on different tasks: study of the structure of the Earth’s crust and upper mantle in the BRZ, active vibroseismic monitoring, and verification of velocity models of the Earth’s crust. To study the structure of the Earth’s crust and the upper mantle, there were done the vibrator-generated wavefield recordings at the stationary regional network of seismic stations in the Buryat and Baikal branches of the Federal Research Center of the GS RAS, as well as the experimental studies involving the mobile networks deployment (ICMMG SB RAS, SIPE RAS, GIN SB RAS). The aim of the work is to carry out deep vibroseismic sounding of the Earth’s crust (vibro-DSS) at the junction of the Siberian platform, the BRZ and the Sayan-Baikal folded area. The methodology is based on the study of vibration seismograms with the determination of arrival times of the main groups of waves and their correlation with the velocity models of the Earth’s crust in the BRZ. A CVO-100 vibrator and a regional network of seismic stations are used to carry out active vibroseismic monitoring of the southern part of the BRZ. The active monitoring area is about 500×200 km. During vibroseismic monitoring, there were done thorough studies of seasonal variations of the vibrator-generated wavefield and the development of techniques for spectral correction of seismograms. A seismic vibrator CVO-100 was used to carry out experimental verification of the velocity models of the Earth’s crust, developed based on the BEST and PASSCAL experimental data. The vibrational deep seismic sounding (vibro-DSS) on the Baikal – Ulan Bator profile was carried out by the ICMMG SB RAS, GIN SB RAS and BB FRC GS RAS (Russia) in cooperation with IAG MAN (Mongolia).

The results of the development of scientific foundation of technology for passive geohydroacoustic monitoring of Arctic seas are presented, including theoretical studies of the conditions for the origin and propagation of wave fields generated by induced geodynamic processes in the layered structure “lithosphere – hydrosphere – ice cover”, the solution of a separate class of problems within the framework of a fundamental scientific problem, related to the search for innovative, environmentally safe geophysical technologies to outline the local heterogeneities, as well as the creation of prototypes, laboratory and full-scale testing of prototypes of new generation ice-based geohydroacoustic buoys. The method for estimating parameters of floating ice (thickness, density, Young’s modulus, Poisson’s ratio) in passive mode was proposed and tested in a field experiment. Particular attention is paid to the state of scientific and practical groundwork regarding the possibilities of developing methods for passive geohydroacoustic monitoring of the Arctic seas.
