This ambitious project focuses on the environmental impact of critical mineral exploration on the ocean floor. Installation of Teledyne’s ADCPs—overseen by DRT—is being managed by CSA Ocean Sciences Inc. The instruments were installed by CSA from the vessel Anuanua Moana, owned by Kiva Marine.
Acting as in situ sensors, the ADCPs will capture vital data on current direction, turbulence, and sediment plume transport. These instruments will be deployed on deep-sea moorings to monitor conditions across the full water column—delivering continuous insights over extended periods.
Teledyne RDI ADCPs are made in the USA under ISO 9001 Certification, with each instrument individually handcrafted and rigorously tested prior to deployment. Designed to perform in challenging ocean environments and with over 50,000 units deployed worldwide over the past 40 years, RDI’s Workhorse ADCPs are proven to deliver reliable performance at extreme depths while providing high‑quality data for long‑term moorings and multi‑month deployments
“Before deep-sea mining can move forward, international regulations demand proof that operations won’t harm marine ecosystems,” said Paul Devine, Subject Matter Expert at Teledyne RDI. “Our ADCP technology provides the high-resolution current and sediment transport data essential for responsible resource development—even in the most challenging environments.”
The project will use the following Teledyne ADCPs:
- 13 Workhorse II 300 khz 6,000 m depth rated ADCPs
- 3 Workhorse II 600 khz 6,000 m depth rated ADCPs
- 2 Workhorse Long Ranger 75 khz 1,500 m depth rated ADCPs
- 2 Workhorse Long Ranger 75 khz 3,000 m depth rated ADCPs
Based on the proven electronics of Workhorse, Teledyne RDI’s flagship product line, the Workhorse II extends the capabilities of this platform, while the Long Ranger offers long-range, self-contained ADCPs.
Frank Johnson, VP of Marine Operations at CSA Ocean Sciences, said: “With decades of collaboration behind us, CSA and Teledyne RDI have advanced side by side. CSA has long depended on RDI’s 24/7 service—sensor selection, setup guidance, and urgent field support, including middle of the night calls—giving CSA the confidence to execute highly reliable deployments even in the harshest deepwater environments.”
“Besides deploying Teledyne RDI ADCPs for the environmental monitoring project in Japan from our vessel Anuanua Moana, Kiva Marine—as part of Ocean Minerals and sister company to Moana Minerals—has recently acquired more Teledyne RDI ADCPs (Workhorse Long Ranger 75khz) for mooring recovery and redeployment activities in the Cook Islands,” said Hans Smit, CEO and President, Ocean Minerals. “The proven reliability of Teledyne RDI instruments, combined with strong technical support, makes them a trusted partner for our deepwater operations.”
The International Seabed Authority (ISA) and regulators recommend that contractors collect at least three years of oceanographic data before mining approval. By delivering high-resolution measurements from multiple depths over extended periods, Teledyne ADCPs are helping Deep Reach Technology and this emerging sector meet and exceed international standards.
