Embodiments of systems and methods for deploying and retrieving a plurality of autonomous seismic nodes from the back deck of a marine vessel using an overboard node deployment and retrieval system are presented. The overboard system may comprise one or more overboard wheels that are actively powered to move in response to changes in movement of the deployed cable. The overboard system may comprise a first overboard wheel with a plurality of rollers and a second overboard wheel configured to detect movement and/or changes in a position of the deployment line. The overboard system may be configured to move the first overboard wheel in response to movement of the second overboard wheel. In addition, the first overboard wheel may comprise at least one opening or pocket configured to hold a node while the node passes across the wheel. Other seismic devices may also pass through the overboard system, such as transponders and weights attached to the deployment cable.
