Seatrec Wins Exclusive License from Sea-Bird Scientific to Manufacture Floats for Argo - An International Program to Monitor the Global Ocean
Seatrec selected in competitive RFP for its revolutionary advancement in ocean monitoring capabilities with its sustainable and renewable energy harvesting system
VISTA, Calif. (May 8, 2025) Seatrec, an underwater drone company, and Sea-Bird Scientific, a leading provider of oceanographic sensors and instrumentation, today announced an exclusive licensing agreement that Seatrec will manufacture Sea-Bird Scientific’s Navis floats for Argo, an international program to monitor the global ocean.
"Our mission is to monitor the ocean on a global scale,” explained Yi Chao, Ph.D., CEO and founder of Seatrec. “This agreement with Sea-Bird makes Seatrec a key provider of autonomous profiling floats to the international Argo program, especially with biogeochemical (BGC) sensors to monitor ocean ecosystems and health."
Under the terms of the agreement, Seatrec will receive exclusive rights to manufacture Sea-Bird Scientific’s Navis float product line. This strategic partnership is expected to combine the strong sensor expertise at Sea-Bird Scientific and the innovative float platform at Seatrec to provide continuous support to the international Argo Program and open new market opportunities that benefit both companies.
"This collaboration with Seatrec represents a significant step in our commitment to providing best-in-class oceanographic sensor solutions," said Jessica Pounds, President of Sea-Bird Scientific. “As we continue to focus on driving innovation in sensors and instrumentation for the entire oceanographic community, we look forward to our partnership with Seatrec to deliver industry-leading float technology to support the emerging BGC Argo Program.”
Seatrec, a dual-use deep tech startup, is the leader in the temperature-powered infiniTE™ float. Powered by a patented technology that harvests energy from ocean temperature differences, the infiniTE™ float can increase ocean data collection by up to 40 times (reducing the Argo float sampling interval of 10 days to every six hours) compared to traditional battery-powered floats, opening new possibilities for power-intensive sensors such as passive acoustic hydrophones for soundscape monitoring, addressing critical challenges in ocean science and defense applications.
Seatrec expects to take purchase orders of Navis floats in early 2026 and begin rolling out the fully integrated Navis floats with customer-requested sensors by late 2026.
About Seatrec
Seatrec designs and manufactures subsea drones that generate electricity from ocean temperature gradients. Our products empower oceanographic researchers to extend mission durations, optimize data collection, and reduce costs. By enabling the integration of advanced sensors previously limited by power constraints, such as hydrophones, we unlock new possibilities for ocean science. The core technology was developed at the NASA Jet Propulsion Laboratory. Seatrec was incorporated in 2016 as a spinoff from the California Institute of Technology.

Seatrec + Naval Postgraduate School Achieve Historic First by Collecting Acoustic Data in Real-Time with Underwater Drones
Seatrec + Naval Postgraduate School Achieve Historic First by Collecting Acoustic Data in Real-Time with Underwater Drones
Hydrophone-equipped underwater drones powered by the ocean’s temperature differences deployed off the coast of Hawaii to provide persistent monitoring of natural and man-made soundscape
VISTA, Calif. – WEBWIRE – Wednesday, January 29, 2025. Seatrec and the Naval Postgraduate School (NPS) today announced the first-ever collection of acoustic data in real-time by underwater drones, also known as autonomous profiling floats, completely powered by the energy harvested from the temperature differences in the ocean. The data capture was made off the coast of Kona, Hawaii, by the Persistent Smart Acoustic Profiler (PSAP) Voyager. Seatrec designed and built the first PSAP Voyager with the unprecedented ability to create its own electricity to power the robust onboard computing capabilities needed to process the large data recorded by a passive acoustic hydrophone used to detect sounds underwater.
The new PSAP Voyager’s ability to generate power leapfrogs previous generations of autonomous profiling floats that are limited by battery power and enables acoustic data to be collected in real-time anywhere in the world’s oceans nearly indefinitely.
“Sound is used to “see” underwater and is vital to understanding the ocean and monitoring the movement of natural and man-made objects,” explains Yi Chao, Ph.D., Seatrec’s CEO and Founder. “Previously hydrophones required power from expensive underwater cables from shore or ships but our PSAP Voyager untethers hydrophones and provides nearly unlimited persistent monitoring of the ocean in an extremely economical way.”
Traditional hydrophones are positioned at depth, often within the SOFAR (SOund Fixing And Ranging) channel, where the sound speed is minimal. Sound is trapped within this SOFAR channel by refraction and can travel over great distances. Hydrophones can be lowered into the SOFAR channel from a ship, which is expensive to operate – often starting at $50,000 per day. They can also be placed on the seafloor and powered by fiber optic cables connected to a shore station on land, but there are only a handful of places with this infrastructure.
Naval forces have an inherent operational reason to be quiet at sea, and the research into ocean noise provides additional insight for the Navy and Marine Corps in planning for future underway operations.
“Passive acoustic listening has many operational and research applications in the Navy,” says John Joseph, the principal investigator and faculty associate for research at the Naval Postgraduate School. “The autonomy and long endurance of Seatrec’s PSAP Voyager provides an unprecedented opportunity to collect acoustic data in real-time for very long periods in remote areas without the expense and logistical tail of ship support.”
Seatrec counts the US Navy’s Office of Naval Research among its early backers and in 2022 launched a precursor to the PSAP - Voyager project in partnership with the Naval Postgraduate School to integrate hydrophones into autonomous, ocean-going robots. The research and development effort was supported by the Consortium for Robotics and Unmanned Systems Education and Research (CRUSER) at NPS, which is funded by the Office of Naval Research to provide a collaborative environment for the advancement of educational and research endeavors across the Navy and Marine Corps.
In 2023, Seatrec was selected for the National Security Innovation Network (NSIN) Propel Hawai’i Accelerator. The program is a partnership between the NSIN and Decisive Point in collaboration with the U.S. Navy’s Pacific Fleet—the world’s largest fleet command encompassing 100 million square miles. Seatrec was selected from a competitive field of over 200 early-stage companies to join an elite cohort of enterprises developing cutting-edge technologies to help the modernization needs of the US Navy and the broader DoD community.
