  • Shearwater has shallow-water, ocean bottom node-on-a-rope (NOAR) capability. We can operate high-quality, safe, efficient operations for large scale NOAR acquisition. 

    While ROV’s are the node deployment method of choice for operating in deep water the NOAR method is highly efficient in shallow to medium water depths. In this method autonomous nodes are attached to passive ropes or wires and fast deployments and retrieval speeds can be achieved by highly automated systems. The NOAR system is similar to a seabed cable system but does not require power and telemetry and can be deployed with almost any receiver spacing. The SW Vespucci is equipped with a NOAR handling system and has acquired a number of surveys using this.
