“Then, you have a system that can last forever - almost indefinitely.”

That’s our founder and CEO, Yi Chao, on the Persistent Subsea Autonomous Profiler (PSAP), featured this week in National Defense Magazine.

PSAP turns the temperature difference between warm and cold ocean water into electricity, so it can keep diving, listening and reporting without coming home to recharge. Its hydrophone and onboard computer process sound at sea and report back in real time. Three PSAPs working together can triangulate a target.

We're excited to be ramping up production in San Diego and soon in Mississippi to deliver the first units to the U.S. Navy.

🌊 We have another Where's the Monk winner!

Congrats to Knut-Frode Dagestad, senior researcher at the Norwegian Meteorological Institute and co-developer of OpenDrift — the very trajectory-modeling framework our first winner, José Manuel Echevarría Rubio, used to win round one! Knut-Frode's prediction landed just 61 km from where The Monk actually surfaced on July 20, 2026.

Round two came down to the same challenge: predict exactly where Seatrec's infiniTE™ float — The Monk — would surface. Predictions landing within 100 km were genuinely hard — only 3 entries managed it.

🎯 Honorable mention to Liesvy Valladares Alfonso, Physical Oceanographer and PhD Candidate at CICIMAR-IPN in La Paz, Mexico — the very same institution as José Manuel — whose prediction also landed within 100 km.

Want the full story, including how Knut-Frode validated his current model before running the forecast? Read it here: https://seatrec.com/we-have-a-winner-wheres-the-monk-contest-part-2/

🎙️ Join us Tuesday, August 18, 2026 at 9:00 AM PDT for our webinar "Finding The Monk: How to Predict Where the Ocean Takes a Float," bringing together the winners of both contests — José Manuel Echevarría Rubio (round one) and Knut-Frode Dagestad (round two) — alongside Paul Chamberlain, Postdoctoral Researcher at Scripps Institution of Oceanography.

🎙️ Join Our Free Webinar: How to Predict Where the Ocean Takes a Profiling Float

Ever wondered how anyone could predict where a drifting ocean float will end up, days ahead, with no live GPS to check against? The winner of our “Where’s the Monk” contest actually pulled it off.

📅 Tuesday, August 18, 2026 at 9:00 AM PDT, we’re hosting a live walkthrough of real trajectory-modeling techniques with our contest winner and Dr. Paul Chamberlain, Postdoctoral Researcher at Scripps Institution of Oceanography.

We’ll cover Lagrangian vs. Eulerian forecasting, the Gulf Stream’s eddies and meanders, and exactly how the winning predictions came together — including how some AI-assisted guesses landed as much as 6x farther off than the winning human prediction.

Big news from our team! 🌊 Seatrec has been awarded $30.8 million by the U.S. Department of War under the APFIT program to accelerate production of our Persistent Subsea Autonomous Profiler (PSAP) — a subsea drone powered by the energy harvested from temperature gradients in the ocean.

This award enables Seatrec to begin low-rate initial production immediately at our California facility, with a planned full-rate production site in Mississippi to meet growing demand. It's a huge validation of years of hard work from our team, born out of technology originally developed at NASA Jet Propulsion Laboratory and Caltech.

"This APFIT award is an important step in our mission of bringing the Navy persistent 24/7 undersea information, covering areas that are presently largely unmonitored," said our CEO and Founder, Dr. Yi Chao.

So proud of this team and grateful for our partners at the Office of Naval Research and the Naval Postgraduate School for their support early on.

🌊 We have a winner!

Our first Where's the Monk contest asked one question: where in the Atlantic would Seatrec's infiniTE™ float — The Monk — surface on July 5, 2026, at 11:59 PM PDT?

The Monk surfaced at 38.5626°N, 50.6690°W after riding the Gulf Stream's eddies and meanders. Predictions landing within 100 km were genuinely hard — only 4 entries managed it!

🏆 Congratulations to José Manuel Echevarría Rubio, PhD Candidate in Marine Sciences at Centro Interdisciplinario De Ciencias Marinas-Ipn, whose prediction landed just 52 km away — closest of all!

🥈 Honorable mention to Ruoying (Roy) He and the Fathom Science team at North Carolina State University, whose prediction also landed within 100 km — along with two other entrants.

The top four entries spanned Mexico, France, and both coasts of the U.S. — talk about global ocean nerds. 🌍

🌊 Big news from Seatrec!

We have been selected as a DEVELOP Phase winner in the U.S. Department of Energy’s Powering the Blue Economy™: Power at Sea Prize, earning a $75,000 award to advance our thermal-powered profiling float technology.

In partnership with ASL Environmental Sciences Inc., we’re integrating the AZFP-pico acoustic sensor onto Seatrec’s infiniTE™ float to measure vertical profiles of zooplankton and mesopelagic biomass through the water column.

Why does this matter?

Zooplankton are tiny, but their impact is enormous. Their daily vertical movements help drive the biological carbon pump, one of the ocean’s most important climate processes. Yet observing that movement over long periods, at high frequency, and across depth has been a major challenge.

By harvesting energy from ocean temperature gradients, Seatrec’s floats can support persistent ocean observations without the same endurance limits as battery-only platforms.

This award helps move us closer to filling a major ocean data gap and expanding what autonomous ocean observing can do.

🌊 The ocean is the most data-rich, least-understood place on Earth. Happy to the scientists and researchers working to change that. .
