A seismic survey system records seismic signals during a marine seismic survey. The system includes first and second clusters, each including a set of autonomous underwater vehicles (AUVs); each cluster being associated with a corresponding first or second unmanned surface vehicle (USV); and a central control unit located on a floating platform and configured to control the first and second USVs. The first USV follows its own path and the first cluster follows the first USV independent of the second USV or the second cluster.

1. A seismic survey system for recording seismic signals during a marine seismic survey, the system comprising: first and second clusters, each including a set of autonomous underwater vehicles (AUVs);each cluster being associated with a corresponding first or second unmanned surface vehicle (USV);
1. A seismic survey system for recording seismic signals during a marine seismic survey, the system comprising: first and second clusters, each including a set of autonomous underwater vehicles (AUVs);each cluster being associated with a corresponding first or second unmanned surface vehicle (USV); anda central control unit located on a floating platform and configured to control the first and second USVs,wherein the first USV follows its own path and the first cluster follows the first USV independent of the second USV or the second cluster. 2. The system of claim 1, wherein the first cluster has the AUVs arranged in a first pattern and the second cluster has a second pattern, different from the first pattern. 3. The system of claim 1, wherein each of the first and second clusters has less than 100 AUVs. 4. The system of claim 1, wherein the central control unit transmits commands via radio links to the first and second USVs. 5. The system of claim 4, wherein the first and second USVs communicate with acoustic modems with the first and second clusters, respectively. 6. The system of claim 1, further comprising: a base station configured to extend a radio range of communication between the first USV and the central control unit. 7. The system of claim 1, wherein the first USV comprises: a housing completely immersed underwater and including plural bays for receiving one or more AUVs of the first cluster during the seismic survey. 8. The system of claim 7, wherein the housing comprises: in each bay, a locking mechanism for locking an AUV when inside the bay;an interface for transferring seismic data from the AUV to a storing device on the housing; anda power connector for transferring electric power to the AUV. 9. The system of claim 7, wherein the housing comprises: a guiding system for guiding an incoming AUV in a corresponding bay. 10. The system of claim 1, wherein the first USV comprises: an acoustic underwater positioning and navigation system for determining a location of each AUV of the first cluster during the seismic survey; andan acoustic modem for transmitting a corresponding location to each AUV of the first cluster. 11. The system of claim 1, wherein the first USV detects positions of AUVs of the first cluster and the second USV detects positions of AUVs of the second cluster. 12. The system of claim 1, wherein the first USV follows a first path and the second USV follows a second path and the two paths are different. 13. The system of claim 1, wherein the floating platform is an oil rig and the first and second USVs are remote controlled from the oil rig. 14. A seismic survey system for recording seismic signals during a marine seismic survey, the system comprising: first and second clusters, each including a set of autonomous underwater vehicles (AUVs);each cluster being associated with a corresponding first or second unmanned surface vehicle;a central control unit located on a floating platform and configured to control the first and second unmanned surface vehicles; anda source vessel that generates the seismic signals,wherein the first unmanned surface vehicle follows its own path and the first cluster follows the first unmanned surface vehicle independent of the second unmanned surface vehicle or the second cluster. 15. A method for recording seismic data using a seismic survey system, the method comprising: deploying first and second clusters, each including a set of autonomous underwater vehicles (AUVs);assigning to each cluster a corresponding first or second unmanned surface vehicle (USV);remote controlling, from a central control unit located on a floating platform, the first and second USVs; andrecording the seismic data with the first and second clusters,wherein the first USV follows its own path and the first cluster follows the first USV independent of the second USV or the second cluster. 16. The method of claim 15, further comprising: sending first location information from the first USV to the AUVs of the first cluster; andsending second location information from the second USV to the AUVs of the second cluster,wherein the location information is related to positions of AUV during the seismic survey. 17. The method of claim 16, further comprising: adjusting a trajectory of an AUV based on location information received from a corresponding USV. 18. The method of claim 15, further comprising: instructing an AUV of the first cluster to dock in a bay of a housing attached to the first USV. 19. The method of claim 18, wherein the AUV determines by itself a need to dock with the housing. 20. The method of claim 18, further comprising: requiring permission from the first USV prior to docking with the housing.
