    Abstract: Systems and methods for retrieving seismic data acquisition units from an underwater seismic survey are provided. The system includes an underwater vehicle with a base and an underwater vehicle interlocking mechanism. The underwater vehicle receives environmental information and identifies a seismic data acquisition unit located on an ocean bottom. The underwater vehicle obtains an indication to perform a non-landing retrieval operation. The underwater vehicle sets a position of the underwater vehicle interlocking mechanism to extend away from the base of the underwater vehicle. The underwater vehicle retrieves the seismic data acquisition unit by coupling the underwater vehicle interlocking mechanism with a seismic data acquisition unit interlocking mechanism. The underwater vehicle stores the seismic data acquisition unit and then sets the underwater vehicle interlocking mechanism in a second position to perform the non-landing retrieval operation for a second seismic data acquisition unit.

    Abstract: The present disclosure is directed to systems, methods, and apparatus for delivering seismic data acquisition units to, and retrieving from, an underwater vehicle. A sensor storage container can be tethered to a surface vessel, which can move on the surface with a non-zero velocity. The underwater vehicle can include a storage compartment to store seismic data acquisition units and a propulsion system to aid the movement of the underwater vehicle. The underwater vehicle also can include passive and active protrusions for coupling with corresponding receptacles on the sensor storage container. The sensor storage container also can include a propulsion system to aid movement of the sensor storage container. The propulsion systems of both the underwater vehicle and the sensor storage container can be controlled to allow the underwater vehicle and the sensor storage container to couple and allow transfer of seismic data acquisition units.

    Abstract: Systems and methods for delivering seismic data acquisition units to an ocean bottom are provided. A system includes an underwater vehicle including with sensors to determine environmental information. A control unit obtains, based on the environmental information and a policy, an indication to perform a fly-by deployment. The control unit sets an angle of a ramp with respect to a base of the underwater vehicle. The control unit identifies a launch event for a seismic data acquisition unit of a plurality of seismic data acquisition units stored in the underwater vehicle, and deploys the seismic data acquisition unit from the ramp towards the ocean bottom based on the identification of the launch event and the environmental information.

    Abstract: A method and apparatus for a seismic cable is described. In one embodiment, a method for performing a seismic survey in a water column is described. The method comprises providing a length of flexible cable from a cable storage device disposed on a vessel to a cable handling device adjacent the cable storage device. The flexible cable comprises a specific gravity that is greater than a specific gravity of water in the water column. The method further comprises routing the flexible cable to pass adjacent a workstation disposed on the vessel, deploying a free end of the flexible cable into the water column, attaching at least one of a plurality of seismic sensor units to the cable as the cable passes the workstation, and controlling the motion of the vessel and the rotational speed of the cable handling device to allow the flexible cable to rest on the bottom of the water column.
