Apparatuses, systems, and methods for monitoring, positioning, and/or guiding a plurality of seismic nodes on or near the seabed by a plurality of acoustic pinging devices coupled to a deployment line and at least one surface buoy. The acoustic pinging devices are configured to emit a unique ID that may be detected by a receiver or transceiver located on each of the surface buoys. The acoustic pinging devices may be coupled to each node or only to a portion of the plurality of nodes (such as every two, three, or four nodes). The monitoring system may be configured to identify the ID, position, depth, and height of each seismic node during travel to the seabed and upon node touchdown with the seabed. A guidance system may be configured to guide the deployment of the deployment cable based upon node position data determined by the monitoring system.
