1. A system for seismic exploration of a submerged sub-surface comprising: 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 housing connected to an upper end of the stem, anda radially extending support zone connected to the housing, said upper end projecting from the seabed; anda 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,wherein said module is configured to be disposed within said housing. 2. A system according to claim 1, in which the base includes a mooring element for an underwater vehicle. 3. A system according to claim 2, in which the module is fitted onto the base by means of a sliding motion then by a rotation about an axis parallel to the direction of the sliding motion. 4. A system according to claim 3, in which the support zone presents orifices extending in a direction not perpendicular to a longitudinal direction of the stem. 5. A system according to claim 1, in which the housing includes a slot for receiving a handle of the module. 6. A system according to claim 1, comprising means for sealing the housing in the absence of a module. 7. A system according to claim 1, in which the support zone presents an acoustic signature enabling identification thereof by a sonar carried by an underwater vehicle. 8. A system according to claim 1, in which the module has a density roughly equal to 1. 9. A system according to claim 1, in which the module includes a clock. 10. A system according to claim 1, in which the module includes means for transmitting and/or receiving of an acoustic signal. 11. A system according to claim 1, in which the stem of the base has a height ranging between 1 and 40 meters. 12. A system according to claim 1, in which the module is electrically connected to the base by a contactless coupling. 13. A system according to claim 12, in which the contactless coupling is a magnetic link. 14. A system according to claim 1, comprising additional bases connected to at least one of said bases by cable. 15. A method of seismic exploration of a submerged sub-surface, comprising the steps of: lowering near a predetermined seabed position, a base having an elongate stem and at least a seismic sensor within said stem, a radially extending support zone being connected to a housing connected to the upper end of the stem,anchoring the stem to the seabed while keeping its upper end projecting from the seabed,connecting a module including data storage means and a power source to the housing by means of an underwater vehicle,repeating the steps above for each seabed position at which seismic data must be acquired, anddisconnecting said modules from the respective bases after completion of the seismic acquisition by means of an underwater vehicle. 16. A method according to claim 15, in which the base is anchored to the seabed by free fall towards the seabed. 17. A method according to claim 15, in which the base is anchored to the seabed by driving said stem into the seabed.
