The present disclosure is directed to loading a helical conveyor for underwater seismic exploration. The system includes a case and a first conveyor having a helix structure provided within the case to support one or more ocean bottom seismometer (“OBS”) units. The case can include a first opening at a first end of the first conveyor and a second opening at a second end of the first conveyor. The system can include a base to receive at least a portion of the case. The system can include a second conveyor positioned external to the case that can move an OBS unit into the first opening at the first end of the first conveyor. The first conveyor can receive the OBS unit and direct the OBS unit towards the second opening at the second end of the first conveyor.

1. A system to deploy ocean bottom seismic (“OBS”) units, comprising: a case;a first conveyor provided within the case to support a first one or more OBS units, the first conveyor having a first helix structure;the case comprising a first opening at a first end of the first conveyor;the case comprising a second opening at a second end of the first conveyor;a base to receive at least a portion of the case;a second conveyor positioned external to the case to support the first one or more OBS units;the second conveyor constructed to move a first OBS unit of the first one or more OBS units into the first opening at the first end of the first conveyor, and the first conveyor constructed to receive the first OBS unit and direct the first OBS unit towards the second opening at the second end of the first conveyor;a third conveyor having a second helix structure provided within the case, the third conveyor configured to support a second one or more OBS units; anda support structure configured to extend through a central axis of the first helix structure of the first conveyor and the second helix structure of the third conveyor. 2. The system of claim 1, wherein the case comprises a first portion to produce drag to dampen rotation of the case moved through an aqueous medium. 3. The system of claim 1, comprising: an elevator configured to position the second conveyor to align the second conveyor with the first opening. 4. The system of claim 1, comprising: a first gate configured to close the first opening,wherein the second conveyor is configured to open the first gate. 5. The system of claim 1, comprising: a first gate configured to close the second opening,wherein the second conveyor is configured to open the first gate to remove the first OBS unit from the helix structure. 6. The system of claim 1, comprising: a crane; anda cable coupled to the crane and the case, the crane configured to raise, lower, or support the case via the cable. 7. The system of claim 1, comprising: a crane; anda cable coupled to the crane and the case, the crane configured to lower the case loaded with the first one or more OBS units onto the seabed via the cable. 8. The system of claim 1, comprising: a crane;a cable coupled to the crane and the case, the crane configured to lower the case loaded with the first one or more OBS units into the aqueous medium; anda fin extending from the case, the fin configured to create force as the case moves through the aqueous medium to dampen rotation of the case. 9. The system of claim 1, comprising: the base configured to contact the seabed and support the case on the seabed. 10. The system of claim 1, comprising: a third opening of the case at a third end of the second conveyor; andan elevator configured to raise or lower the second conveyor, the elevator configured to align the second conveyor with the first opening to load the first one or more OBS units onto the first conveyor via the first opening, and align the second conveyor with the third opening to load the second one or more OBS units onto the third conveyor via the third opening. 11. The system of claim 1, wherein the first conveyor is an unpowered gravity conveyor, and the second conveyor is powered. 12. A method for deploying ocean bottom seismic (“OBS”) units, comprising: providing a case;providing a first conveyor having a helix structure and provided within the case, the first conveyor configured to support one or more OBS units, the case comprising a first opening at a first end of the first conveyor and a second opening at a second end of the first conveyor;providing a base to hold the case in a substantially vertical position;providing a second conveyor positioned external to the case and configured to support the one or more OBS units;loading, via the second conveyor, a first OBS unit of the one or more OBS units into the case via the first opening at the first end of the first conveyor;directing, via the first conveyor, the first OBS unit received from the second conveyor towards the second opening at the second end of the first conveyor;providing a third conveyor having a second helix structure within the case, the third conveyor configured to support a second one or more OBS units; andproviding a support structure configured to extend through a central axis of the first helix structure of the first conveyor and the second helix structure of the third conveyor. 13. The method of claim 12, wherein the case comprises a first portion to produce drag to dampen rotation of the case moved through an aqueous medium. 14. The method of claim 12, comprising: aligning, via an elevator, the second conveyor with the first opening. 15. The method of claim 12, comprising: opening, via the second conveyor, a first gate closing the first opening. 16. The method of claim 12, comprising: opening, via the second conveyor, a first gate closing the first opening; andremoving, via the second conveyor, the first OBS unit from the first conveyor. 17. The method of claim 12, comprising: positioning, using a crane coupled to the case via a cable, the case into the aqueous medium. 18. The method of claim 12, comprising: positioning, using a crane coupled to the case via a cable, the case onto the seabed, the case comprising the one or more OBS units. 19. The method of claim 12, comprising: positioning, using a crane coupled to the case via a cable, the case loaded with the one or more OBS units into the aqueous medium; andcreating, using a fin extending from the case, force as the case moves through the aqueous medium to dampen rotation of the case. 20. The method of claim 12, comprising: contacting the seabed with the base; andsupporting, with the base, the case on the seabed.
