Systems and methods for deployment and retrieval of ocean bottom seismic receivers. In some embodiments, the system includes a carrier containing receivers. The carrier can include a frame having a mounted structure (e.g., a movable carousel, movable conveyor, fixed parallel rails, or a barrel) for seating and releasing the receivers (e.g., axially stacked). The structure can facilitate delivering receivers to a discharge port on the frame. The system can include a discharge mechanism for removing receivers from the carrier. In some embodiments, the method includes loading a carrier with receivers, transporting the carrier from a surface vessel to a position adjacent the seabed, and using an ROV to remove receivers from the carrier and place the receivers on the seabed. In some embodiments, an ROV adjacent the seabed engages a deployment line that guides receivers from the vessel down to the ROV for “on-time” delivery and placement on the seabed.

1. A system to facilitate deployment of ocean bottom seismic (OBS) units secured to a deployment line at spaced intervals, comprising: a vehicle configured to travel through an aqueous medium;a guide, coupled to a side of the vehicle, configured to travel through the aqueous medium and control the deployment line, the guide comprising: a first member coupled to the side of the vehicle;a second member coupled to the side of the vehicle and opposite the first member, wherein the first member and the second member are configured to control the deployment line threaded between the first member and the second member; anda plate, coupled to the side of the vehicle, positioned between the first member and the second member to contact an OBS unit to direct the OBS unit to contact a seabed as the deployment line passes through the guide. 2. The system of claim 1, wherein the guide includes a movable traction member. 3. The system of claim 2, wherein the guide is attached to a lower side of the vehicle. 4. The system of claim 2, wherein the traction member includes at least one wheel. 5. The system of claim 2, wherein the traction member includes at least one tractor track. 6. The system of claim 1, comprising: a traction member configured to engage or propel the deployment line. 7. The system of claim 1, wherein the guide includes opposing, movable traction members. 8. The system of claim 7, wherein the guide is configured to receive the deployment line threaded through the guide so as to be between the opposing, movable traction members. 9. The system of claim 1, wherein the plate is further configured to facilitate coupling the OBS unit to the seabed. 10. The system of claim 1, wherein the guide includes opposing members and the plate positioned between the opposing members. 11. The system of claim 10, wherein the guide is configured to cause the OBS unit that is on the deployment line to contact the seabed. 12. The system of claim 11, wherein the guide is configured to urge the OBS unit downward into coupling contact with the seabed. 13. The system of claim 1, wherein the guide includes opposing members and a horizontal member positioned between the opposing members, the guide configured to facilitate downward movement of the OBS unit that is on the deployment line such that the OBS unit comes into coupling contact with the seabed.
