A coupling device is provided for a sensor unit having at least one sensor located within a housing. The coupling device includes at least one supporting portion, wherein the supporting portion is configured for maintaining the sensor unit in a stable position, with the coupling device either resting on or being buried into the ground, and at least one rod, arranged in a plane which is essentially perpendicular to a peripheral surface of the supporting portion and linked to the supporting portion. The coupling device further includes a fastener for connecting the sensor unit to the coupling device. The supporting portion maintains the sensor unit in a stable position when resting on the ground, while the rod provides an additional stiffness to the housing.

Coupling device for seismic sensors

A system and method for detecting marine mammals and mitigating sound effects on them. The mammal detecting and mitigating system includes a first mammal monitoring system and a second mammal monitoring system. The first and second mammal monitoring systems are configured to be deployed away from each other, and the first and second monitoring systems communicate to each other such that the first mammal monitoring system is informed about a presence of a marine mammal detected by the second mammal monitoring system.

Seismic shooting with mammal mitigation system and method

A module is provided for processing geophysical data coming from at least one geophysical sensor. The module includes: an electronic board configured to enable the processing of geophysical data captured by the at least one geophysical sensor; and two cable sections each including, at one extremity, a connector designed to be connected to said electronic board. Each connector forms one half-shell and is arranged so as to cooperate with one other half-shell in such a way as to form a shell in which the electronic board is placed.

A stress-relief device is provided, which is configured for being mounted on a geophysical equipment or node connected to at least two cables. The device includes a case configured for surrounding the geophysical equipment or node and for making at least an opening for enabling a connection between each of the at least two cables and the geophysical equipment or node. The device also includes a housing for housing a portion of each of the two cables, the housing being configured for substantially preventing any movement of said portions of the two cables.

Stress-relief device for geophysical equipment or node

A connector is provided, which is configured for being connected to a similar connector. The connector has a global cylindrical shape around a longitudinal axis and includes a connection zone having comprising at least one electrical contact. A housing extends at least partly around the connection zone and has at least two projecting members. A cylindrical locking nut surrounds the housing and is at least partly movable relative to the housing. The housing and the locking nut are configured for respectively cooperating with corresponding locking nut and housing of the similar connector.

Connector, in particular for underwater geophysical operations

A seismic sensor, having a body which incorporates means for detecting and/or measuring waves, and, in the extension of said body, a tip for insertion into the ground, said tip extending between an upper end and a lower end, wherein said tip has at least two wings which together give said tip a V-shaped profile, said wings having between them at least one cavity which extends from said upper end to close to said lower end.
