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.”

Seatrec and The USM Team to Improve Hurricane Forecasting and Monitor Critically Endangered Rice’s Whale
VISTA, Calif. – WEBWIRE – Wednesday, May 17, 2023. Seatrec, a startup company unlocking clean, renewable power for ocean research and commerce, and the Roger F. Wicker Center for Ocean Enterprise at The University of Southern Mississippi (USM), today announce the signing of a memorandum of understanding (MOU) aimed at improving hurricane rapid-intensification forecasting and monitoring critically endangered Rice’s whales in the Gulf of Mexico.
The MOU calls for the deployment of two types of Seatrec’s infiniTE™ floats each customized for different missions using the system’s first-of-its-kind modular design and clean, renewable power technology that harvests electricity from the ocean’s temperature differences.
One type of float will feature a suite of instruments to take measurements as frequently as three times per day to track water temperatures and other data that scientists believe contribute to the rapid intensification of hurricanes like Katrina, Irma, and Ian. The second type of float will operate with a passive acoustic hydrophone to monitor the endangered Rice’s whales with less than 100 remaining members of the species clustered in the Gulf’s northeastern waters.
“There is a critical need to better understand the Gulf of Mexico both in terms of its impact on humans in the form of extreme weather events and human impact on the marine life,” points out Yi Chao, Ph.D., the CEO and founder of Seatrec. “Having the flexibility to quickly and inexpensively deploy different mission-specific instrument suites on deep-diving, autonomous floats powered by a clean, renewable power source gives scientists like those at USM important tools to gather data not possible with previous technologies.”
Rice’s whales are members of the baleen whale family Balaenopteridae. With likely fewer than 100 individuals remaining, Rice’s whales are one of the most endangered whales in the world. Recovery of the species depends upon the protection of each remaining whale.
The MOU follows Seatrec’s completion of the six-month Gulf Blue Navigator program that is administered by USM and SeaAhead with partners, including Jackson State University. The program is designed to help scale blue technology startups.
“Power has long been a limiting factor that often restricts the types of instruments deployed in the ocean, how long they can last, and the amount of persistent data they can collect,” explains Dr. Kelly Lucas, USM’s Vice President for Research. “Seatrec’s ability to provide clean, renewable power to vertically integrated and modular instrument suites opens the door to a host of applications that will help us better understand and protect the ocean.”
Added Hailey Bathurst, Program Manager for the Gulf Blue Navigator, “Seatrec exemplifies what the Navigator program is meant to do: help blue tech startups find traction in the Gulf of Mexico, work with the core facilities at USM, and plug into a supportive ecosystem. This MOU and the others being finalized between USM and the inaugural Gulf Blue Navigator cohort members truly represents the potential of the program.”
The Roger F. Wicker Center for Ocean Enterprise serves a global hub for advancing Uncrewed Maritime Systems, ocean data science, maritime cyber research, and blue tech workforce training. The 62,500-square-foot center consists of multiple facilities bringing together federal, industry, and academic partners, creating a collaborative environment to accelerate the development and launch of new technology in the fast-growing ocean economy.
Entrepreneurs and startups developing solutions to global challenges utilize the center to capitalize on world-class ocean research capabilities and connect to university research scientists.
“The Gulf Blue Navigator program has already begun to make an economic impact to the Mississippi Gulf Coast,” said Dr. Jason McKenna, Director of Research, Development, Testing, Evaluation & Training at the Wicker Center. “This is the first of many follow-on initiatives between USM’s world-class research centers and the Navigator’s program’s first graduating cohorts and demonstrates the ability of our coastal research ecosystem to partner with and help grow blue technology in Mississippi.”
Seatrec’s pioneering energy harvesting system uses phase change materials to harness energy from temperature differences between the ocean’s various depths. 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. Traditional floats (commonly known as Argo) 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. Seatrec’s infiniTE™ floats are able to sample as frequently as three times per day providing 30x more data than the standard Argo floats.
Whale 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.
Seatrec will establish a long-term presence in the Gulf of Mexico to support the MOU missions with a satellite office provided by the Gulf Blue Navigator program while its headquarters will remain in Vista, California.

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.

Seatrec Partners with Naval Postgraduate School to Study Ocean Soundscape
Seatrec and Naval Postgraduate School Launch a New Project to Study Ocean Soundscape and Chart Impact of Noise Pollution on Ocean Environment
Hydrophone-equipped autonomous float powered by the ocean’s temperature differences will listen for clues to help minimize the impact of human noise
VISTA, Calif., November 14, 2022 - Seatrec and the Naval Postgraduate School (NPS) today launched a new project to study the impact of human-made noise on the ocean soundscape and marine life. An Ocean Sonics hydrophone installed on a Seatrec autonomous sustainably powered float system is the first of its kind and enables acoustic data to be collected anywhere in the world’s oceans nearly indefinitely.
“When it comes to understanding the ocean, sound is everything, but persistent listening is extremely difficult and expensive,” explains Yi Chao, Ph.D., Seatrec’s CEO and Founder. “The Naval Postgraduate School is a great partner, and we are excited to help them research acoustic impacts more effectively and affordably. Providing the necessary scientific instruments that are powered by the ocean’s own temperature differences opens the door to persistent monitoring of our oceans in an economical manner.”
Studies show that noise from humans adversely affects a broad range of organisms including whales, fish, jellyfish, squid and octopuses. High noise levels even contribute to deformities among scallop larvae. However, the true extent of impacts from noise pollution is not well understood.
The emergence of the COVID-19 pandemic in 2020 brought with it unprecedented silence as human activities related to commerce and recreation all but ceased. That reduction in human activity gave scientists a new baseline for ocean noise and highlighted the impact that human noise pollution has on life in the ocean.
“Sound is the way the Navy and many marine animals ‘see’ through the ocean,” says John Joseph, the principal investigator and faculty associate for research at the Naval Postgraduate School. “It’s critical that we understand the reach and scale of the collective human impact on the ocean soundscape to inform strategies for protecting marine species and improving naval operations for the defense of our ships and Sailors at sea.”
The COVID-related silence also offered a powerful argument for broadening the deployment of hydrophones to monitor ocean noise and to include hydrophones on autonomous platforms to provide real-time acoustic data for the dynamic management of vulnerable areas. Underwater gliders have been used in this role and are also used by the Navy for passive surveillance, but they are powered by batteries with a limited lifetime and are usually confined to near the coast.
Traditional hydrophones are positioned at depths around 1,000 meters (3,300 feet), within the SOFAR (SOund Fixing And Ranging) channel, where the sound speed is minimum. Sound is trapped within this SOFAR channel by refraction and can travel slowly 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.
“Our hydrophone float powered by Seatrec’s patented energy harvesting system can be deployed into the SOFAR channel anywhere over the world’s ocean,” said Yi. “It offers nearly unlimited persistent surveillance of the ocean without the need for ship support as the float battery is recharged by the temperature differences in the ocean.”
Naval forces have an inherent operational reason to be quiet at sea, and the research into ocean noise may provide 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, and our students at NPS conduct applied research to meet naval-unique needs for at-sea operations that require measurements of ambient noise, understanding soundscapes and monitoring of marine mammals,” added Joseph. “Because the Seatrec platform will be long-lived, and is remotely operated, it can provide extensive time series of information to oceanographers and naval researchers to measure acoustics and how they are changing from human impact including climate change.”
This research effort is 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.
This project comes on the heels of Seatrec’s recent launch of Project NEMO – an initiative in partnership with The Nippon Foundation-GEBCO Seabed 2030 Project to install an active acoustic echosounder to Seatrec’s thermally powered float.
