A system for seismic exploration of a submerged sub-surface comprises a plurality of bases () located at predetermined seabed positions, each base comprising an elongate stem penetrating the seabed, at least a seismic sensor () within said stem, a radially extending support zone () connected to the upper end of the stem, said upper end projecting from the seabed, and a respective plurality of modules () each incorporating a data storage unit and a power source, each module being mechanically and electrically connected to the upper end of said stem, said module being capable of being connected to, and disconnected from, the base by an underwater vehicle.

System for seismic exploration a submerged subsurface including implanted bases

A device for controlling steering of a towed underwater object, in particular a towed linear acoustic antenna. The device comprises a body having a longitudinal axis, the body being provided with a fastener for fastening it releasably to the towed object, and a plurality of stabilizer fins, each of which is coupled to the body and extends along an axis that is transverse to the longitudinal axis of said body, the angular position of each fin relative to the body being pivotable about its transverse axis by control, so as to modify the angles of inclination of said fins.
