Seatrec’s infiniTE™ Float Surpasses 1,000 Dives for Naval Postgraduate School
Seatrec’s infiniTE™ Float Surpasses 1,000 Dives for Naval Postgraduate School - Ushering a New Era of Long-Endurance Persistent Ocean Monitoring
Autonomous profiling float delivers oceanographic and acoustic data every six hours, fully powered by harvested energy from temperature gradients, marking a breakthrough in persistent, long-endurance ocean monitoring and real-time reporting for defense, scientific research, and exploration
Seatrec, a leader in thermal-powered subsea drones, today announced a major milestone in oceanographic research with the 1,000th dive completed by its infiniTE™ float, deployed off the coast of Kona, Hawai’i, in collaboration with the Naval Postgraduate School (NPS). The float reached depths of 700 meters, diving into the deep sound channel for optimal listening, while producing more electricity than it consumed. The first-of-its-kind, an ocean-powered float carries a passive acoustic hydrophone, records sound data, processes data onboard, and transmits information and intelligence in real-time.
“Reaching 1,000 profiles is a critical endurance benchmark for our technology that unlocks exciting opportunities in ocean research and exploration,” explained Yi Chao, Ph.D., CEO and founder of Seatrec. “It is a significant achievement to demonstrate the capabilities of our infiniTE™ float to power multiple sensors with the energy from the ocean rather than relying on a limited battery.”
Launched on November 5, 2024, in collaboration with the NPS and funded by NPS’s Consortium for Robotics and Unmanned Systems Education and Research (CRUSER) program, this pioneering float known as the Persistent Smart Acoustic Profiler (PSAP) has harvested over 10 megajoules (2,800 Wh) of clean, renewable energy using Seatrec’s patented infiniTE™ technology, which converts natural ocean temperature gradients into electricity. Over just seven months, the infiniTE™ float has generated 2x the energy of a conventional battery-powered float while maintaining a net-positive energy balance. The harvested energy powers a Conductivity-Temperature-Depth (CTD) sensor and a passive acoustic hydrophone, onboard data processing, and satellite data transmissions, ushering in a new era of long-endurance, persistent ocean float missions.
NPS’s mission is to deliver defense-focused graduate education and interdisciplinary research to enhance the Navy’s operational effectiveness and technological leadership. “Through the Meteorology and Oceanography (METOC) program, NPS drives impactful results via innovative research and technology co-development. Our METOC student, Lieutenant Kirk Bienvenu, is analyzing PSAP data in his master’s thesis to advance maritime intelligence. By collaborating with startups like Seatrec, NPS equips officers with skills to address complex global threats, ensuring Navy readiness in dynamic operational theaters,” said John Joseph, the principal investigator and faculty associate for research at the Naval Postgraduate School.
PSAP represents an innovative way to collect and transmit oceanographic and underwater acoustic information essential to supporting critical Navy mission areas, including Undersea Warfare, Seabed Warfare, ISR and Maritime Domain Awareness. “Operating independently of other theater assets, PSAP provides a real-time feed of critical information directly to the warfighter, enhancing their tactical decision making,” Joseph said.
By combining a CTD sensor with a hydrophone, the infiniTE™ float enables simultaneous monitoring of both the ocean’s physical properties and acoustic soundscape. This breakthrough marks a turning point for persistent long-endurance, multi-sensor ocean observing missions once limited by battery constraints.
This milestone adds to a series of recent achievements by Seatrec, including:
- Selection by Sea-Bird Scientific as the exclusive manufacturer of the Navis floats for the international Argo program.
- A successful Arctic Power Station test at Michigan Tech’s Great Lakes facility.
- Recognition as a winner of the U.S. Department of Energy’s Powering the Blue Economy™: Power at Sea Prize.
As the infiniTE™ float continues to demonstrate unmatched endurance and modularity, Seatrec is accelerating its vision to deliver scalable, self-powered solutions for defense, researchers, government agencies, and industry partners operating across the world’s oceans.

Oceanographic Team Wins NOAA Funding for Underwater Soundscape Study
Oceanographic Team Wins NOAA Funding for the Autonomous Profiling Float Powered by Ocean’s Temperature Differences to Study Underwater Soundscape
World-class experts from Seatrec, Integral Consulting, Naval Postgraduate School, MBARI, and Scripps/UC San Diego to build a long-endurance float for gathering directional acoustic data in the deep ocean powered by clean, renewable energy.
VISTA, Calif. – WEBWIRE – Wednesday, September 13, 2023
Seatrec, Integral Consulting, Monterey Bay Aquarium Research Institute (MBARI), Naval Postgraduate School, and Scripps Institution of Oceanography at the University of California San Diego today announce funding from the National Oceanic & Atmospheric Administration’s (NOAA) Ocean Exploration. The two-year funding award supports the integration of a commercial, off-the-shelf directional hydrophone manufactured by GeoSpectrum Technologies Inc. onto Seatrec’s newly launched infiniTE™ float to study the ocean’s soundscape.
“Sound is a critical component to understanding the ocean, but the power demands of acoustic sensors make it impossible to listen for extended periods, not to mention the additional power required to process the acoustic data in order to reduce the data size for satellite communication,” points out Dr. Yi Chao, the Founder and CEO of Seatrec. “Seatrec’s newly launched infiniTE™ float, capable of generating electricity from temperature differences in the ocean, opens up vast new areas of knowledge to help us better understand and protect the ocean.”
Studies show that noise from humans adversely affects a broad range of organisms, from shellfish larvae to large marine mammals. Acoustic sensors, or hydrophones, are needed to quantify the impact of these noises; however, current technology limits their use to short deployments from expensive-to-operate ships or to areas where power is supplied via a cable from shore.
“A robust understanding of deep-sea acoustics is invaluable across a range of scientific, environmental, economic, and national security needs,” explains Dr. Kaus Raghukumar, an acoustic oceanographer at Integral Consulting. “The integration of a vector sensor into Seatrec’s profiler will leverage Integral’s NoiseSpotter® technology and expertise. A directional hydrophone allows for a better understanding of the location of sound sources, such as marine mammals.”
Seatrec’s infiniTE™ float provides a new platform for deep-water acoustic observations over unprecedented durations in remote regions.
“As part of NOAA Ocean Exploration’s mission to lead, coordinate, and fund expeditions around the world, we are uniquely situated to promote partners in the maritime community - like this creative team - who can advance ocean exploration technologies and acquire critical data and information about various marine environments,” said Jeremy Weirich, Director of NOAA Ocean Exploration. “Supporting this collaboration to develop and test an innovative sensor on a new underwater platform is important for filling data gaps about our ocean and enabling scientific discovery.”

Introducing the infiniTE™ Float
Seatrec Launches infiniTE™ Float, a First-Of-Its-Kind Modular Platform with “Plug-and-Play” Sensors Powered by the Ocean’s Temperature Differences
Unprecedented flexibility from clean, renewable power greatly expands the use of sensors required for seafloor mapping and soundscape study along with the ability to generate up to 3 profiles per day to unlock improved hurricane rapid-intensification forecasting
SAN DIEGO (Feb. 14, 2023) – Seatrec, a renewable energy company that harvests energy from temperature differences in the environment, today announces the launch of its infiniTE™ Float. The first-of-its-kind modular platform features the ability to mix and match an expanded array of power-hungry sensors – some never before supported by autonomous profiling floats – by generating clean, renewable electricity from the ocean’s temperature differences.
The announcement comes on the opening day of the Oceanology International Americas event in San Diego.
“Power limitations remain a key challenge to critical ocean research,” explains Yi Chao, Ph.D., the CEO and Founder of Seatrec, who is a panelist at the event’s Ocean Observation and Sensing 1 Session. “Our next-generation infiniTE™ floats solve that problem in a sustainable way and unlock the future of oceanographic research by facilitating long-term, data-gathering deployments that were previously impossible.”
Seatrec’s pioneering energy harvesting system harnesses temperature differences between the ocean’s various depths to drive the phase change of specific materials. These materials contract and expand creating pressure that’s captured and converted into electricity. The clean, virtually limitless power frees scientists to use sensors that typically require shore-supplied power or direct ship support via tethering.
The infiniTE™ float platform’s “plug-and-play” modularity vertically integrates different sensors tailored to particular areas of study.
Hurricane Forecasting
Better understanding the rapid intensification of major storms and hurricanes is a particularly pressing goal as annual economic losses from such storms are estimated at $54B. Legacy floats typically only profile once every 10 days, which is insufficient to measure the intensification of storms that can surge in as little as 24 hours. Seaterc’s infiniTE™ floats are able to sample as frequently as three times per day providing 30x more data than its competition.
Seafloor Mapping
Only 20% of the global seafloor is mapped by in-water sensors with high resolution and mapping the remaining 80% using ships is estimated to cost as much as $3B. Echosounders are impossible to mount on legacy floats because of power limitations. Seatrec’s power generation technology clears the way for the use of low-cost floats to conduct bathymetry surveys at depth, autonomously, and at a fraction of the cost of using ships.
Soundscape Monitoring
Studies show that noise from humans adversely affects a broad range of organisms, including marine mammals. Hydrophones are needed to quantify the impact of these noises on marine mammals. Hydrophones mounted on Seatrec’s infiniTE™ floats provide an inexpensive, autonomous platform to gather soundscape data at varying depths for years at a time.
The launch of the infiniTE™ Float Platform follows on the heels of a notable year of partnerships for Seatrec. The Naval Postgraduate School recently partnered with Seatrec to study the ocean soundscape and chart the impact of noise pollution on Blue Whales by using a hydrophone-equipped infiniTE™ float. Also, Seatrec and The Nippon Foundation-GEBCO Seabed 2030 Project signed an MOU to launch Project NEMO (Novel Echosounder to Map the Ocean) to map the gaps of the global seafloor in remote areas where it is too costly for ships to access.
