Abstract

The possibility of recording weak seismic waves using fiber-optic accelerometers placed on the ice cover is considered. The results of experimental studies of a fiber-optic accelerometer with a threshold sensitivity 10^-7 m/s² are presented. This experiment was held in winter in the Amur Bay (Sea of Japan). The results of recording seismic signals propagating in the ice cover during the motion of objects on ice are presented. The results of recording weak seismic signals propagating in the ice cover during the operation of a low-frequency hydroacoustic emitter are presented. The obtained results prove the possibility of using the presented fiber-optic accelerometer for recording weak seismic waves propagating in the ice cover to solve seismic monitoring problems in the Arctic offshore.
