Ocean-bottom node deployment is provided. An example system includes a pulley system which includes a pulley, a traction wheel on a marine vessel and a transport line looped around the pulley and the traction wheel. A plurality of release units are coupled to the transport line at spaced intervals and are configured to selectively secure and release a plurality of ocean-bottom nodes connected respectively thereto. A deflector connects to the pulley system and is configured to position the pulley system relative to the marine vessel. A central control unit is communicatively coupled to the plurality of release units and to the deflector and the traction wheel and includes a central processor. The central processor controls positioning of the pulley system with the deflector and commands each of the plurality of release units to release each of the plurality of ocean-bottom nodes at a predefined position.
