A groundbreaking scientific expedition was just completed off the west coast of �鶹��ý Island in search of something unexpected: fresh water beneath the ocean floor. Researchers from the University of �鶹��ý at ����ԴDz� and Scripps Institution of Oceanography teamed up for a two-week offshore imaging survey in July 2025, through a contract with the Natural Energy Laboratory of �鶹��ý Authority (NELHA) and funding from the �鶹��ý State Legislature.

The goal was to confirm the existence of a potentially massive underground reservoir of fresh or brackish water hidden beneath the seafloor—an idea that challenges conventional understanding of island hydrology.

“If proven, this deep water could explain long-standing mysteries about �鶹��ý Island’s water cycle—namely, why observed coastal discharge doesn’t match estimated groundwater recharge,” said Peter Kannberg, associate researcher at the (HIGP) in the UH ����ԴDz� , who led the survey. “In simple terms, a lot of water is missing from current models.”

The roots of this investigation trace back to 2018, when scientists first detected anomalies suggesting a deep, confined aquifer where none should exist. Their theory? Rainwater may be funneled underground trapped beneath layers of volcanic basalt and ash, extending far beneath the basal freshwater lens and even miles offshore.

“If confirmed, this hidden aquifer could reshape our understanding of island hydrology and inform future water resource planning—offering a potential new source of fresh water in a region increasingly affected by drought and climate change,” said Alex Leonard, senior project manager for NELHA.

“If a significant fraction of freshwater is escaping through these deep aquifers, then we need to re-calculate how much water can can be withdrawn from the nearshore basal lens for human consumption and how much needs to remain in these shoreline aquifers to provide nutrients to the reefs and nearshore marine environment,” added Don Thomas, HIGP faculty who has spent decades studying water and subsurface features across the Hawaiian Islands.

High-tech imaging survey takes to the sea

The 2025 survey used advanced electromagnetic imaging techniques. Instruments were deployed on the seafloor to listen for electromagnetic echoes, while a 150-foot-long towed sensor emitted a low-power signal that is recorded on a 3,300-foot-long receiver array. The study spanned two areas: north of Kiholo Bay to Honōkohau Harbor and the coastline south of Kailua Bay to Kealakekua.

The team will now begin processing data from the surveys to determine whether this reservoir is present and better understand how much water may be in this hidden offshore aquifer.

“We are now applying state-of-the-art technologies to better characterize the complexity of island hydrology—advancing knowledge that could fundamentally improve how we manage and sustain freshwater resources across volcanic islands both here and abroad,” said Amir Haroon, faculty member at HIGP, who studies water resources on Oʻahu and Maui.

NASA has developing instruments for Moon travel through the Artemis campaign. Two instruments, including UH’s, will be integrated onto a Lunar Terrain Vehicle (LTV), which astronauts will drive on the Moon. Another instrument will orbit the Moon.

“I’m so excited to see this project come into reality,” said Matthew Siegler, associate researcher in the (HIGP) at the UH ����ԴDz� , who will lead the team developing the Lunar Microwave Active-Passive Spectrometer (L-MAPS). “�鶹��ýhas become a major player in the search for ice on the Moon. This instrument selection takes us to the next level.”

The L-MAPS instrument will help determine what is below the Moon’s surface, the heat production of the Moon and search for possible locations of buried ice. The UH science and spacecraft engineering team will work in partnership with instruments developed at NASA’s Jet Propulsion Laboratory (JPL) and the German Technical University at Dresden.

Siegler and deputy principal investigator Shannon Brown, a researcher at JPL, and their team have been designing and testing the L-MAPS instrument for more than five years, preparing for an opportunity to get to the Moon. Being selected for the LTV instrument team moves the development to the next stage—the build—which will primarily take place at JPL.

Outfitting the first crew-driven vehicle on the Moon in 50 years

The LTV vehicle is part of NASA’s efforts to explore the lunar surface as part of the Artemis campaign and is the first crew-driven vehicle to operate on the Moon in more than 50 years. Designed to hold up to two astronauts, as well as operate remotely without a crew, this surface vehicle will enable NASA to achieve more of its science and exploration goals over a wide swath of lunar terrain.

In the , Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington, D.C., emphasized that the Artemis Lunar Terrain Vehicle will advance humanity across the lunar frontier toward exploration and discovery and added that the instruments planned for the LTV combine the best of human and robotic exploration.

When combined, data from the L-MAPS and other instruments will paint a picture of the components of the lunar surface and subsurface to support human exploration and will uncover clues to the history of rocky worlds in our solar system.

“I feel incredibly lucky to be working on lunar research in a time when NASA has prioritized the Artemis return of humans to the Moon,” said Siegler. “Work like this is possible because of researchers at the University of �鶹��ý working for years leading in planetary science and developing spaceflight technologies. It is exciting to be in the right place and time to ride this wave.”

Collaboration is key to success

At JPL, the L-MAPS instrument will be built with components from Deutsches Zentrum für Luft- und Raumfahrt and Ohio State University. Final testing will be done partially at UH ����ԴDz�. The instrument production and operation on the Moon will be managed by HIGP faculty Miguel Nunes and Trevor Sorensen and will include many roles for UH faculty, undergraduate and graduate students.

A program at the University of �鶹��ý at ����ԴDz� that supported dozens of career development activities for women in geosciences and community outreach was terminated by the loss of federal funding.

In April, Barbara Bruno, project lead and faculty member at the in the UH ����ԴDz� (SOEST), was given a termination notice with instructions to immediately close operations on the National Science Foundation (NSF)-funded program. About two-thirds of the nearly $200,000 budget was forfeited when the grant was terminated.

“SOEST is �鶹��ý’s largest producer of geoscience graduates—alumni who go on to monitor volcanic hazards, predict extreme weather, conduct assessments of environmental impacts, ensure sustainable use of �鶹��ý’s freshwater resources, and more,” said Bruno. “I think the biggest impact of this termination is the loss of professional development opportunities for women. STEM is hemorrhaging women—we need programs to keep them.”

The NSF award supported a mini-grant program, , that funded geoscience workforce development in two ways: outreach and community engagement to attract the next generation of STEM professionals; and professional development for current SOEST students and early career scientists.

Loss of career development and outreach opportunities

Through the mini-grants program, female students, post-doctoral researchers, staff and faculty submitted applications to secure funding to attend professional meetings, technical or career development workshops; or engage in field work or research collaborations. For example, this project supported activities of a co-writing group for women in SOEST and multiple student-oriented groups focused on diversity, equity and inclusion within UH.

The federal funding cut also resulted in terminating two months of Bruno’s salary and several mini-grants that were in process. Funding was pulled from a Palauan graduate student who is pursuing her doctoral degree in the Marine Biology Graduate Program and studying the unique and diverse coral communities of Ngermid Bay in the Republic of Palau.

The successfully completed outreach and community engagement efforts supported by this program include training for ; and workshops, hands-on activities, and presentations to community members and middle and high school students that focused on and .

“We were also actively soliciting applications for the next round of CASA funding when we received the termination notice,” said Bruno. “Ending this grant eliminates the support for future professional development opportunities and K–12 and community engagement.”

Next steps

On May 28, �鶹��ý Attorney General Anne Lopez and 15 other attorneys general filed a lawsuit to stop illegal attempts to cut critical NSF programs and funding that help maintain the U.S.’ position as a global leader in STEM. Bruno submitted a declaration in support of this federal lawsuit, attesting to the adverse impacts of the sudden termination of her NSF grant. Bruno is actively pursuing alternative funding sources to support these initiatives.

Liliane Burkhard, a University of �鶹��ý at ����ԴDz� research affiliate, was selected as one of two for the European Geosciences Union (EGU) 2025 General Assembly in Vienna, Austria. In this week-long role spanning April and May, Burkhard created a large-scale installation that bridges science and art, specifically, transforming discarded conference posters into a floating cloud sculpture.

“Science is how we explain the world, art is how we make sense of it,” said Burkhard, a planetary geologist in the (HIGP) at the UH ����ԴDz� School of (SOEST). “I am deeply honored to be selected as an Artist in Residence for EGU25, where I can merge my passions for science and art in a meaningful way.”

The Artist in Residence program offers scientist-artists an opportunity to engage with scientific research in a dynamic setting and be inspired by the many new discoveries being presented at one of the largest international geoscience conferences.

“My installation served as a metaphor for how scientific ideas form and evolve, often starting as nebulous concepts that, over time, take shape and lead to something tangible,” Burkhard shared. “The act of reusing the physical posters to craft something new reflects the iterative process of research itself. In this, I hope to encourage viewers to consider how ideas, much like clouds, are always in flux: constantly forming and dissolving, yet impactful in the way they inspire both imagination and progress.”

With the installation, “Clouds of Insights,“ Burkhard created a space for reflection and conversation, while also emphasizing sustainability by repurposing materials from the conference itself.

In addition to her work as a sculptural mixed media artist, Burkhard has conducted planetary science research previously as a graduate student in the SOEST and now as a HIGP research affiliate. Through her investigations, she has explored the geology and histories of icy moons in our solar system, including Saturn’s largest moon, , and Jupiter’s largest moon, .

Sharing the science-art connection

Burkhard and Emily Costello, a researcher at HIGP, co-hosted a short course at the EGU conference, “Unlocking creativity through paper sculptures: Overcoming blocks in writing and idea generation.” They offered more than 60 attendees an opportunity to use the art of paper folding and sculpture to overcome creative blocks, spark fresh ideas and explore the transformative connections between hands-on creativity and scientific innovation.

“There was quite a lot of interest overall, which was very exciting!” said Burkhard. “The participants said they very much enjoyed doing something tactile and hands-on to help them with their work as scientists, connecting themselves to art and seeing things from a different perspective.”

Emily Costello, a planetary scientist at the University of �鶹��ý at ����ԴDz�, was as one of eight participating scientists to join its to the Jupiter Trojan asteroids. These asteroids are remnants of the early solar system trapped on stable orbits associated with, but not close to, the planet Jupiter.

On the Lucy mission, Costello will contribute to the goal of understanding the nature and history of Trojan asteroids by providing insights into the role of meteoritic impacts in shaping the surfaces of the Trojans.

“Impacts are a pervasive geological process on small bodies, so it is critical that we accurately decipher how these impacts shape the formation and evolution of the asteroids,” said Costello, who is a researcher at the in the UH ����ԴDz� (SOEST).

The impact of impacts

Launched in 2021, the spacecraft is the first space mission to explore the diverse group of small bodies known as the Jupiter Trojan asteroids. Trojan asteroids orbit in two “swarms” that lead and follow Jupiter in its orbit around the Sun.

Impacts from meteors mix the surface of these bodies and muddle geologic layers, called strata. Impacts play a crucial role in erasing and homogenizing certain surface features, such as crater rays, and in the evolution of chemical and physical characteristics. Costello will provide the Lucy team with a key piece of the surface geology puzzle, leveraging her impact modeling expertise and targeted observations of craters and the material they propel outward.

“The history written and rewritten by impacts will influence the interpretation of all observations by the Lucy mission’s scientific instruments that view Trojan surfaces,” Costello said. “So, it’s thrilling to be able to help interpret the first ever close-up look at these likely ancient asteroids.”

More about the Lucy mission

Over its 12-year mission, Lucy will explore a record-breaking number of asteroids, flying by three asteroids in the solar system’s main asteroid belt, and by eight Trojan asteroids that share an orbit around the Sun with Jupiter. Lucy also will fly by Earth three times to get a push from its gravity, making it the first spacecraft to return to the vicinity of Earth from the outer solar system.

To gain valuable insight into the groundwater flow near Red Hill, Oʻahu, researchers at the University of �鶹��ý at ����ԴDz� began a dye tracer study in February. Using a method that has been approved by the U.S. Environmental Protection Agency and the �鶹��ý Department of Health, the team injected a fluorescent compound to a monitoring well and will study its migration through the aquifer over the spring of 2025.

Following the jet fuel leaks from storage tanks in 2014 and 2021, there has been significant concern from community members and scientists about the safety of drinking water in the area. After the 2021 release of jet fuels, water pumped from Red Hill Shaft no longer supplies public drinking water but rather is entirely discharged to Halawa Stream as part of ongoing recovery efforts at the request of regulators.

Recent geophysical and hydrological studies have begun to provide a better understanding of the regional geology and groundwater flow rates and directions. The dye tracer study will validate those findings and provide data sets to inform current and future modeling efforts. Rhodamine water tracer (WT) was selected for this study because it is non-toxic, straightforward to measure, breaks down in sunlight, doesn’t bind to soils and washes away easily.

“Fluorescent dyes, such fluorescein and rhodamine, have been used for decades by the U.S. Geological Survey to understand river dynamics and were safely used to study the groundwater migration of freshwater discharge off the coast of Lahaina, Maui in 2011,” said Toomas Parratt, researcher in the at the UH ����ԴDz� and lead hydrogeologist on the study.

The team injected dye into RHMW08, a quarter of a mile upgradient from Red Hill Shaft (RHS), which was shut down as a public drinking water supply following the November 2021 fuel leak. However, extraction at RHS is still ongoing with a granular activated carbon treatment system prior to discharge to Halawa Stream. For the tracer study the water extraction rate was temporarily increased to over 4 million gallons per day, consistent with the permitted rate, to maximize the recovery of the injected dye.

The water pumped from RHS will be monitored every 10 minutes to determine the concentrations of the tracer dye in the extracted water. The arrival time of the dye at RHS and the total mass captured by RHS’ pump will allow for the estimation of groundwater velocities and the efficacy of dye recovery. The concentration of dye will also be monitored after treatment by the Navy’s activated charcoal filters to ensure adequate dye removal prior to discharge to Halawa Stream, since it is disconnected from the public drinking supply.

“From the ongoing hydrogeological studies the majority of the dye is expected to be captured by RHS and will not discharge to any surface water bodies, including streams, springs and near-shore seeps since the dye was injected below sea level within the capture zone of RHS,” Parratt emphasized.

Additional information

Preliminary results from the dye tracer study will be shared publicly in summer 2025.

A popular life-saving military-approved emergency signaling system began as an idea by alumni Rob Yonover. The inventor said UH played a pivotal role in shaping his life and career, earning a PhD in geology and geophysics in 1989.

The , Yonover’s groundbreaking invention, which can be spotted from miles away, originated during a moment of potential crisis. While piloting a plane to Kauaʻi, he experienced engine trouble and realized—even if he safely ditched in the ocean—rescuers would have difficulty locating him.

“As a PhD student at the under Dr. John Sinton, I learned to tackle challenges from multiple angles,” Yonover said. The unique environment of UH allowed him to explore problems both in the lab and deep in nature, from underwater volcanoes to remote research settings.

Although an appearance on Shark Tank didn’t secure funding, his SeeRescueStreamer is now widely used, including aboard SpaceX flights and across all branches of the U.S. military.

He urges current UH students to persevere and manage their time wisely in pursuing their passions—using spare time to focus on innovation.

“Don’t quit your day job, so you can one day quit your day job,” he said.

Yonover also emphasizes the importance of fostering creativity for societal progress.

He said, “By staying creative and innovative, you’re more likely to solve global or personal challenges.”

Yonover’s journey from UH student to successful inventor showcases the university’s lasting impact on its alumni and their communities.
