It is proposed a seismic data acquisition device () intended to be placed on an ocean bottom floor, comprising a polymeric casing () defining a chamber that houses at least art of a data acquisition system (); and a metallic device () in which the polymeric casing () is trapped, the metallic device () comprising two metallic beams () that extend on opposite sides of the polymeric casing (). It is also proposed a method for assembling such a device and a corresponding method for seabed seismic data acquisition.

Hybrid seismic data acquisition device and corresponding methods

An ocean bottom node for collecting seismic data, the ocean bottom node including a compounded housing including an electronics housing and a pinger housing, electronics located inside the electronics housing, and a battery pack configured to supply electrical power to the electronics. The pinger housing is permanently open to an ambient water while the electronics housing is sealed from the ambient water, and the pinger housing is configured to selectively and directly attach to the electronics housing.
