A method and apparatus for storing, deploying and retrieving a plurality of seismic devices is described. The apparatus includes a ramp device coupled to a portion of a trailing end of a vessel, a cable handling device positioned between the ramp device and a leading end of the vessel to define a cable path across the ramp device, and at least one conveyor system having a first end located adjacent the ramp device and a second end extending toward the leading end of the vessel. A deployment method includes providing nodes from a storage area to a workstation where the nodes may be attached to a cable. A retrieval method includes routing a cable through a workstation to detach nodes from the cable section and transfer the detached nodes to the storage area.
