The Case Study of using ocean-bottom seismographs based on R-sensors' sensors in the Arctic to assess seismic hazards.
To find a solution, there were used the first results of several pilot deployments of the ocean-bottom seismographs developed by Shirshov Institute of Oceanology and Ilyinskiy A.D., a sole proprietor, in 2018 – 2020.
The seismographs are equipped with two types of broadband molecular-electronic sensors of two modifications: CME-4111 (120 sec - 50 Hz) and CME-4311 (60 sec - 50 Hz). The sensors were made by R-sensors, Russia.
The research was conducted in the Laptev sea under different conditions.
The main characteristics of the broadband molecular-electronic sensors such as permissible installation angles, operation temperature ranges, sensitivity and dynamic ranges appeared suitable for obtaining records under the Arctic conditions to solve the seismological problems.
