The present disclosure is directed to underwater seismic exploration with a helical conveyor and skid structure. The system can include an underwater vehicle comprising a sensor to identify a case having a hydrodynamic shape, wherein the case stores one or more ocean bottom seismometer (“OBS”) units. The underwater vehicle includes an arm. The underwater vehicle includes an actuator to position the arm in an open state above a cap of the case, or to close the arm. The underwater vehicle can move the arm to a bottom portion of the case opposite the cap. An opening of the case can be aligned with the conveyor of the underwater vehicle. The conveyor can receive, via the opening of the case, a first OBS unit of the one or more OBS units. The conveyor can move the first OBS unit to the seabed to acquire seismic data from the seabed.

1. A system to acquire seismic data from a seabed, comprising: an underwater vehicle comprising a sensor to identify a case having a hydrodynamic shape, wherein the case stores one or more ocean bottom seismometer (“OBS”) units;the underwater vehicle comprising an arm;the underwater vehicle comprising an actuator to position the arm in an open state above a cap of the case, or to close the arm;the underwater vehicle comprising a conveyor;the underwater vehicle configured to move the arm to a bottom portion of the case opposite the cap, an opening of the case aligned with the conveyor of the underwater vehicle;the conveyor configured to receive, via the opening of the case, a first OBS unit of the one or more OBS units; andthe conveyor configured to move the first OBS unit to the seabed to acquire seismic data from the seabed. 2. The system of claim 1, wherein the case comprises a first portion that is hydrodynamic and a second portion configured to produce drag to dampen rotation of the case through an aqueous medium. 3. The system of claim 1, wherein the case comprises a helix structure to store the one or more OBS units and convey the one or more OBS units from a second opening of the case to the opening of the case, a first distance between the opening and the cap less than a second distance between the second opening and the cap. 4. The system of claim 1, wherein the case comprises a plurality of helix structures to store the one or more OBS units. 5. The system of claim 1, wherein the underwater vehicle comprises at least one of a remotely operated vehicle or an autonomously operated vehicle. 6. The system of claim 1, comprising: a receptacle in contact with the seabed and configured to support the case;the conveyor of the underwater vehicle configured to receive the first OBS unit from the case on the receptacle. 7. The system of claim 1, wherein the conveyor is a first conveyor, the system comprising: a second conveyor configured to insert the first OBS unit into the case via a second opening of the case; anda helix structure in the case to receive the first OBS unit via the second opening, the first OBS unit moves towards the opening via the helix structure. 8. The system of claim 7, wherein the helix structure comprises an unpowered gravity conveyor. 9. The system of claim 7, wherein: the case is placed on a base configured to support the case; andthe first OBS unit is inserted into the case placed on the base. 10. The system of claim 7, comprising: the second conveyor configured to insert a second OBS unit of the one or more OBS units into the case via a third opening of the case; anda second helix structure in the case to receive the second OBS unit via the third opening, the second OBS unit moving, via the second helix structure, towards a fourth opening of the case below the second opening. 11. The system of claim 1, comprising: an alignment mechanism comprising a runner configured to align the opening of the case with the conveyor. 12. A method of acquiring seismic data from a seabed, comprising: identifying, via a sensor of an underwater vehicle comprising a conveyor and an arm, a case constructed to store one or more ocean bottom seismometer (“OBS”) units;positioning the underwater vehicle so that the arm is in an open state above a cap of the case;closing, by an actuator of the underwater vehicle, the arm;moving, by the underwater vehicle, the arm toward a bottom portion of the case opposite the cap, an opening of the case aligned with a conveyor of the underwater vehicle;receiving, by the conveyor via the opening of the case, a first OBS unit of the one or more OBS units; andplacing, by the underwater vehicle, the first OBS unit on the seabed to acquire seismic data from the seabed. 13. The method of claim 12, comprising: detecting, by the sensor, a ping from a transponder on the case; andusing, by the underwater vehicle, the ping to position the arm in the open state above the case. 14. The method of claim 13, comprising: determining, by the underwater vehicle, a depth of the underwater vehicle relative to the case based on the ping. 15. The method of claim 12, comprising: moving, by the underwater vehicle, the arm in the open state towards a cable connected to the cap of the case that supports the case in an aqueous medium. 16. The method of claim 12, wherein the case comprises a first portion that is hydrodynamic and a second portion configured to produce drag to prevent rotation of the case through an aqueous medium. 17. The method of claim 12, wherein the case comprises a portion having a conical shape or a domed shape. 18. The method of claim 12, comprising: aligning, via an alignment mechanism comprising a runner, the opening of the case with the conveyor. 19. The method of claim 12, comprising: locking, in a notch of the arm, a runner of the case to align the opening of the case with the conveyor. 20. The method of claim 12, comprising: opening, by the underwater vehicle, a gate on the case that blocks the first OBS unit from moving through the opening of the case. 21. The method of claim 12, comprising: opening, by the underwater vehicle, a gate on the case that blocks the first OBS unit from leaving the opening of the case; andrunning, by the underwater vehicle, the conveyor to retrieve the first OBS unit from the case. 22. The method of claim 12, comprising: receiving, by the conveyor of the underwater vehicle, via the opening of the case, the first OBS unit from a helix structure in the case supporting the one or more OBS units;receiving, by the conveyor via the opening of the case, a second OBS unit of the one or more OBS units, the second OBS unit moving down the helix structure towards the opening; andreceiving, by the conveyor via the opening, a third OBS unit of the one or more OBS units, the third OBS unit moving down the helix structure towards the opening responsive to the conveyor receiving the first OBS unit and the second OBS unit.
