1. A monitoring system for the deployment of seismic nodes on or near the seabed, comprising:

  • a plurality of ocean bottom seismic nodes coupled to a deployment cable;

    a plurality of acoustic pingers configured to emit a ping at a predetermined interval, wherein each of the plurality of acoustic pingers is coupled to a separate one of the plurality of seismic nodes;

    a surface vessel, configured to deploy the plurality of seismic nodes in a body of water; and

    at least one surface buoy coupled to the surface vessel by a first buoy connecting line, wherein each surface buoy comprises an acoustic receiver configured to detect the emitted pings from the plurality of acoustic pingers,wherein the monitoring system is configured to monitor a touchdown position of the plurality of seismic nodes on the seabed and communicate the touchdown position of each of the plurality of seismic nodes with the surface vessel at approximately the same time as touchdown.
