Teledyne RDI Ocean Surveyor (OS) ADCP

The Industry Standard for Deep-Water Vessel-Mounted Profiling

Product Overview 

The Teledyne RDI Ocean Surveyor is the preeminent vessel-mounted Acoustic Doppler Current Profiler (ADCP) designed for open-ocean research and commercial operations. While the Workhorse Mariner handles coastal depths, the Ocean Surveyor is built for the "blue water" fleet, capable of profiling currents at depths exceeding 1,000 meters while the vessel is underway at speeds of 15 knots or more.

Its defining feature is the phased-array transducer. Unlike traditional ADCPs that use four separate "piston" transducers, the Ocean Surveyor uses a single flat-faced electronics array to generate all four beams. This makes the unit significantly more compact, easier to install in a ship's sea chest, and more flush with the hull to reduce drag and flow noise.

  • Phased-Array Transducer: A single, flat-faced unit that pings all four beams simultaneously. This increases data density and reduces the size and weight of the transducer compared to traditional designs.
  • Broadband & Narrowband Modes: * Broadband: Used for high-resolution profiling in the upper water column.
    • Narrowband: Swapped in for maximum depth penetration when the ship moves into deep ocean basins.
  • VMDAS Software: The "Vessel-Mount Data Acquisition System" is the standard controller for the OS series, providing real-time data display, GPS/Gyro integration, and data logging.
  • 19" Rack-mount Electronics: The system’s "brains" are housed in a standard rack-mounted chassis in the ship’s dry lab, connected to the hull-mounted transducer via a single deck cable.
