Abstract: It is described an underwater anti-dragging system for acoustic receivers. The system comprises a metal alloy frame comprising a base (1) for promoting fixation to an underwater substrate, a storage cell (2), adapted to enclose an acoustic receiver, and a protective arched structure (3) inside which the storage cell (2) is positioned. Such configuration therefore prevents the system from being dragged by the action of external agents, such as bottom operating fishing gears and coastal waves. The present application also relates to a monitoring system, comprising the underwater anti-dragging system described and acoustic receivers.

Abstract: A submersible node and a method 10 and system 100 for using the node to acquire data, including seismic data is disclosed. The node incorporates a buoyancy system 16 to provide propulsion for the node between respective landed locations by varying the buoyancy between positive and negative. A first acoustic positioning system is used to facilitate positioning of a node when landing and a second acoustic positioning system is used to facilitate a node transiting between respective target landed locations.

Abstract: A seismic pressure and acceleration sensor (222) can include a hydrophone (298) having a volume (296) encapsulated by an enclosure (246). The enclosure can include, a pressure-sensitive surface (227-1) and a pressure-insensitive support structure (292). The sensor can also include an accelerometer (294) positioned within the encapsulated volume. The accelerometer is mechanically isolated from the pressure-sensitive surface and mechanically coupled to the pressure-insensitive support structure.
