Sentinel ADCP
The global leader in high accuracy data collection...

Workhorse Sentinel ADCP
For over twenty years, Teledyne RD Instruments has been the preeminent supplier of Acoustic Doppler Current Profiling (ADCP) instrumentation for open ocean applications. RDI’s vessel-mounted Ocean Surveyor family of ADCPs continues to raise the bar, collecting detailed maps of the distribution of water currents and suspended materials through the water column and along the ship’s path—at depths and resolutions previously considered unattainable. In real time, the ADCP is also used to aid in situ decision-making, to adapt field operations, and to understand current regime characteristics.

Versatility: Direct reading or self contained, moored or moving, the Sentinel provides precision current profiling data when and where you need it most.
A solid upgrade path: The Sentinel has been designed to grow with your needs. Easy upgrades include pressure, bottom tracking, and directional wave measurement.
Precision data: Teledyne RDI’s patented BroadBand signal processing delivers very low-noise data, resulting in unparalleled data resolution and minimal power consumption.
A four-beam solution: Teledyne RDI’s patented 4-beam design improves data reliability by providing a redundant data source in the case of a blocked or damaged beam; improves data quality by delivering an independent measure known as error velocity; and improves data accuracy by reducing variance in your data.
Budget an issue? This product is available in our new value priced basic Express Configuration. Same broadband quality, with basic current profiling capabilities >>learn more

Sentinel ADCP Applications

	Highlighted Application: ADCPs for Real-Time Observatories ASA's COASTMAP used in Narragansett Bay Real-Time Observation System >>read full story

	Highlighed Application:ADCPs aid in Treasure Hunt ...The ship sank at the entrance to a channel between two of the islands. Heavy tidal currents, funneled through the islands, are exacerbated by strong winds. Once the Sauternes was located, approximately 100m down, a self-contained RD Instruments 300kHz Workhorse Sentinel ADCP™ was bottom-mounted in the area to determine the patterns of current fluctuation. >>Read full story

	Highlighed Application: Innovative ROV/ADCP Combination Extends Range Fugro GEOS Innovation in Gulf of Mexico Fugro GEOS had a problem: their client BHP was about to drill the second-deepest well in the world, on the Walker Ridge Block in the Gulf of Mexico. The well was located at a depth of 2680m (8800 feet) in an area where water currents could threaten the marine riser. Traditional ADCP (acoustic Doppler current profiler) current measurement equipment could only reach up a little over 1000 meters in good conditions. What to do? Get innovative, that’s what. >>read full story

	Highlighed Application: ADCP Data Helps Moves Big Rig Imagine the costs and risks involved in moving an oil-drilling rig to a location affected by both tidal currents and the Gulf Stream. or a recent operation, Coastal Ocean Associates (COA) of Nova Scotia used a new approach. They installed a downward-looking 300 kHz Workhorse Sentinel ADCP™ on a buoy moored adjacent to the destination production platform. >>read full story
