Ocean Observer III
38kHz (OOIII38DR) Long-Range Direct-Reading (Real-Time) ADCP (3rd Generation)
The Ocean Observer III 38 kHz ADCP combines the field-proven 38 kHz phased array ADCP transducer with field-proven electronics into a single package that is capable of profiling >1000 m. This design makes it ideal to be mounted from an oil platform, over the side of a vessel, and in surface buoys.

Description
Since 1997 Teledyne RD Instruments (TRDI) has been providing ADCPs that have proven in the field they can profile beyond 1000 m from research vessels travelling at speeds >15 knots and from offshore oil and gas platforms during exploration work. That same technology has now allowed us to create the Ocean Observer III 38 kHz ADCP. We have combined our field-proven 38 kHz phased array ADCP transducer with our field-proven electronics into a single package that is capable of profiling >1000 m. This design makes it ideal to be mounted from an oil platform, over the side of a vessel, and in surface buoys.
Product Features:
- Field-Proven Hardware Functionality: Phased-array transducer technology >18 years. Electronics/firmware >5 years
- Field-Proven Profiling Range: 1000 m profiling range on more than 100 installations worldwide for >18 years
- Compact Size: Patented phased-array transducer with integrated electronics in a single package
- Dual Profiling Modes: Independent or interlaced longrange and high-resolution modes to optimize for deployment requirements
- Integrated Sensors: Heading, pitch, roll, temperature, pressure, and HEM sensors
- Fit for use: Collect real-time 1000 m profiles from just about any surface platform or mooring
