DIGITAL RECORDING MODULE FOR UNDERWATER RESEARCH Russian patent published in 2020 - IPC G01V1/38 

FIELD: measurement technology.

SUBSTANCE: invention relates generally to geophysical measurement systems, and specifically to seismic technologies for data collection and sensors. Invention is capable of simultaneously recording seismic and acoustic signals, realizing the seismic waves separation principle depending on the propagation direction. Technical solution is capable of receiving, digitizing, processing of accumulating or transmitting a recorded seismic-acoustic array of measurements. Invention can be used as an independent measuring complex, and as part of bottom braids, by means of cables being connected in series into a single measuring circuit. Invention can be used to solve tasks of seismic exploration in transit zones and on shelf, seismic and acoustic observations of water areas, monitoring of underwater in that situation, including in arctic region, etc.

EFFECT: invention provides improved quality of measurement data owing to use of a unique component base, molecular-electronic geophones as linear motion sensors and molecular-electronic hydrophones as sensors for recording an acoustic field in a medium; including invention reduces existing mass and dimensions parameters while maintaining high signal-to-noise ratio of device.
