A system and method for deployment of a plurality of seismic recorder assemblies from a survey vessel on the ocean bottom is disclosed. The seismic recorder assemblies are self contained, autonomous nodal devices which are capable of receiving and recording reflected seismic energy and storing the data locally while operating for an extended period of time. The assemblies each have two or more attachment points for the connection of separate connecting cable segments.

1. A seismic data recorder array configured to be deployed on a bottom of a body of water, the seismic data recorder array comprising a plurality of individually powered autonomous seismic data recorders reversibly interconnected by separate mechanical connecting segments, each adjacent pair of seismic data recorders being reversibly connected by a corresponding mechanical connecting segment, each such mechanical connecting segment containing no electrical or optical communication means or electrical or optical conductors, and wherein adjacent connecting segments are not attached to one another and the seismic data recorders are configured not to communicate with one another when deployed in the array on the bottom of the body of water. 2. The seismic data recorder array of claim 1, wherein a maximum distance between adjacent seismic data recorders is established by a length of the respective connecting segment. 3. The seismic data recorder array of claim 1, wherein each seismic data recorder is reversibly connected to two separate and detached connecting segments, each segment being configured to connect to an adjacent seismic data recorder. 4. The seismic data recorder array of claim 1, wherein each of the seismic data recorders comprises a housing having at least two attachment points for reversible attachment to the connecting segment. 5. The seismic data recorder array of claim 1, wherein each of the seismic data recorders comprises a housing having at least two separate and spaced apart attachment points for reversible attachment to the connecting segments. 6. The seismic data recorder array of claim 1, wherein each seismic data recorder has a housing with first and second generally opposite end portions, the housing having a first connecting segment attachment point located on the first end portion and a second connecting segment attachment point located on the second end portion. 7. The seismic data recorder array of claim 1, wherein each of the seismic data recorders further comprises: a housing having at least two separate and spaced apart attachment points for reversible attachment to the connecting segments;at least one receiver enclosed in the housing for receiving seismic signals; anda power source enclosed in the housing for providing electrical power to the receiver. 8. The seismic data recorder array of claim 7, further comprising: a processor configured to control the operation of the receiver; anda memory device coupled to the receiver and configured to record the seismic signals. 9. The seismic data recorder array of claim 1, further comprising an anchor interconnected to one of the recorders. 10. The seismic data recorder array of claim 1, further comprising a floatable marker connected to at least one of the recorders. 11. The seismic data recorder array of claim 1, wherein the connecting segment comprises a metallic cable or chain. 12. The seismic data recorder array of claim 1, wherein the connecting segment comprises a non-metallic rope. 13. A seismic data recorder array configured to be deployed on the bottom of a body of water, the seismic data recorder array comprising a plurality of individually powered autonomous seismic data recorders reversibly interconnected by separate mechanical connecting segments, each adjacent pair of seismic data recorders being reversibly connected by a corresponding mechanical connecting segment, each such mechanical connecting segment containing no electrical or optical communication means or electrical or optical conductors, wherein adjacent connecting segments are not attached to one another and each of the autonomous seismic data recorders comprises a housing including at least two separate and spaced apart attachment points for attachment to the connecting segments corresponding thereto. 14. The seismic data recorder array of claim 13, wherein each housing includes first and second generally opposite end portions, each housing having a first connecting segment attachment point located on the first end portion and a second connecting segment attachment point located on the second end portion. 15. The seismic data recorder array of claim 13, wherein each autonomous seismic data recorder further comprises: at least one receiver enclosed in the housing for receiving seismic signals; anda power source enclosed in the housing for providing electrical power to the receiver. 16. The seismic data recorder array of claim 13, wherein each autonomous seismic data recorder further comprises: a processor configured to control the operation of the receiver; anda memory device coupled to the receiver and configured to record the seismic signals. 17. The seismic data recorder array of claim 13, further comprising an anchor interconnected to at least one of the seismic data recorders. 18. A method of deploying a seismic data recorder array on the bottom of a body of water, the seismic data recorder array comprising a plurality of autonomous individually powered seismic data recorders, each seismic data recorder having at least two connecting segment attachment points corresponding thereto, each pair of adjacent seismic data recorders being reversibly interconnected by a mechanical connecting segment containing no electrical or optical conductors, adjacent connecting segments not being attached to one another, the method comprising: reversibly affixing a first connecting segment to a first attachment point on a first seismic data recorder;reversibly affixing the first connecting segment to a first attachment point on a second seismic data recorder;reversibly affixing a second connecting segment to a second attachment point on the second seismic data recorder, anddeploying the recorders into the body of water;wherein the seismic data recorders are not configured to communicate the one another when deployed in the array on the bottom of the body of water. 19. The method of claim 18, wherein the first and second seismic data recorders each have a housing having generally opposite first and second end portions and wherein; the first attachment point of each seismic data recorder is located on the first end portion of that seismic data recorder; andthe second attachment point of each seismic data recorder is located on the second end portion of that seismic data recorder. 20. The method of claim 18, further comprising interconnecting a floatable maker with at least one seismic data recorder.
