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.

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.

Seatrec Selected for Gulf Blue Navigator Program

Seatrec Wins Spot in Inaugural Gulf Blue Navigator Program to Bring Ocean Innovation to the Gulf of Mexico

The University of Southern Mississippi Research Foundation-led initiative aims to recruit technology startups focused on improving ocean health, securing critical infrastructure, increasing coastal resilience and driving the Blue Economy

VISTA, Calif. – WEBWIRE – Monday, November 7, 2022 Seatrec, a renewable energy company that harvests energy from temperature differences in the environment, today announces that it was selected as one of six startups to join the inaugural Gulf Blue Navigator Program established by the University of Southern Mississippi Research Foundation and SeaAhead. Seatrec and the other startups in the new program were selected from a pool of 48 applicants across 12 countries.

The Gulf Blue Navigator program provides innovative, ocean-focused startups with market access to the Gulf of Mexico region, proximity to federal agencies, technical facilities, and expertise. These blue technology startups will leverage the existing strengths and capabilities of the Mississippi Gulf Coast and shorten the timeline of product development and market access.

“The Gulf of Mexico is a critically important area both economically and in terms of people affected by hurricanes,” explains Yi Chao, Ph.D., CEO and Founder of Seatrec. “Addressing the challenges facing the Gulf - from better predicting hurricanes to developing sustainable economic growth - requires innovative technology and Seatrec is excited to be part of the inaugural cohort.”

There is evidence to support that rapid intensification of major hurricanes - like Katrina, Irma and Ian - is strongly influenced by ocean conditions below the surface but current methods do not allow timely subsurface measurements over a large area.

Seatrec’s innovation to harvest energy from the ocean’s temperature differences can reduce the data collection interval from 10 days to 8 hours - 30 times more data than the battery-powered alternative - and increase the spatial coverage. This new wellspring of data provides a missing piece to improve the hurricane forecast, especially during rapid intensification.

Before the hurricane season in 2022, Seatrec successfully deployed two ocean-powered floats in the Gulf of Mexico to demonstrate the concept of operation. Support from the Gulf Blue Navigator program will allow Seatrec to expand the number of floats to be deployed before the next hurricane season in 2023 and collect the data needed to provide timely and accurate predictions of hurricane rapid intensification.

The program will also help Seatrec expand the development of clean, renewable power solutions for commercial applications across industries from transportation to aquaculture.

Startups participating in the program are provided access to advanced interactive workshops taught by practitioners in the field, site visits with large industry and federal agencies, co-working space at the historic Gulf and Ship Island Building in Gulfport, and customized mentorship to meet the needs of each startup. The program will kick off the first week of November with the cohort visiting all three Coastal counties as a first step to developing partnerships to accelerate commercialization.

Seatrec and Seabed 2030 Launch Project NEMO, the “Last Great Expedition” to Map Ocean’s Most Remote Spot

Autonomous profiling floats equipped with echosounders will map the ocean near Point Nemo – the farthest point in the ocean from land

VISTA, Calif. – WEBWIRE – Wednesday, March 23, 2022. Seatrec and The Nippon Foundation-GEBCO Seabed 2030 Project today announce Project NEMO (Novel Echosounder to Map the Ocean) via a memorandum of understanding to map the area in the ocean farthest from land near Point Nemo. The project marks one of the last great expeditions to explore the most remote and mysterious area on the planet in the spirit of efforts to chart unknown regions of the Amazon and poles during previous centuries. 

“Point Nemo is particularly challenging and expensive to study and map because it’s 2,688 kilometers (1,670 miles) from the nearest land, which makes it emblematic of the difficulties that scientists face in understanding and mapping the ocean as a whole,” explains Yi Chao, Ph.D., CEO and Founder of Seatrec. “Successfully deploying technology that can accurately and inexpensively map the most remote point in the ocean will help us chart a way forward to the world’s first high-resolution map of the seafloor.”

Just over 20% of the seafloor is mapped at high-resolution leaving an area roughly equivalent to the surface of Mars uncharted. Knowledge of the ocean’s topography provides basic information for science, economy, education, management and geopolitics. Applications as diverse as climate modeling, tsunami forecasting, marine protection and management, communication cable and pipeline planning, all require reliable seafloor maps.

Seabed 2030 – a flagship program of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030) – addresses that vital need through an international effort to facilitate the complete mapping of the seafloor by 2030.

“Mapping the seafloor will have a direct impact on the future of our planet, and as a result, that of humanity,” says Jamie McMichael-Philips, Seabed 2030 Project Director. “Cutting-edge technology like Project NEMO is critical to helping us achieve our goal of mapping the seafloor by 2030. ”

Experts estimate that it will cost up to $5B to map the 80% uncharted seafloor using traditional methods such as ships that burn diesel fuel and emit carbon dioxide into the atmosphere. Seatrec’s transformative technology harvests energy from the ocean temperature difference and provides a cost-effective and sustainable solution to deploy a fleet of subsea robots at a fraction of the cost of ships.

Leading Project NEMO is seafloor mapping pioneer Larry Mayer, Professor and Director of the Center for Coastal and Ocean Mapping at the University of New Hampshire.

“The clock is ticking on the international community’s unprecedented effort to map the seafloor so we can understand and protect the ocean’s resources,” emphasizes Mayer. “Next-generation ocean mapping technologies – like Seatrec’s – are vital to getting the data we need in a scalable and cost-effective way.”
