The University of 鶹ý is set to play a pivotal role in a new national effort to strengthen America’s seafood supply and expand sustainable aquaculture. The National Oceanic and Atmospheric Administration announced the creation of the Cooperative Institute Fostering Aquaculture Research and Markets (CIFARM).

Funded by an initial $13.5 million investment for its first year, this five-year cooperative institute aims to harness partnerships with researchers to unlock the potential of U.S. marine aquaculture. The University of New Hampshire will serve as the host institution, with UH participating as one of five core consortium members in this competitive national program.

The UH research team is being led by Associate Professor Chatham Callan out of the UH Hilo (PACRC). Callan is joined by co-investigators Professor Maria Haws of PACRC, Associate Research Professor Erik Franklin of the in the School of Ocean and Earth Science and Technology at UH Mānoa, and 鶹ý Sea Grant Associate Director for Extension Darren Okimoto and several other UH Faculty partners.

“Being selected as a core member of CIFARM is a testament to the decades of world-class aquaculture research happening right here in 鶹ý,” said Callan. “Through our partnerships with Native Hawaiian communities, we draw on a tradition of ocean stewardship and fishpond engineering that stretches back centuries. Our UH team is excited to bring that unique Pacific perspective and expertise to the national stage. By focusing on cutting-edge tech, environmental forecasting, and real-world marine demonstration projects, we are actively building the blueprint for a more resilient, self-sufficient seafood industry.”

$24B in imported seafood annually

CIFARM‘s core mission is to solve real-world challenges affecting seafood producers and consumers while reducing the nation’s reliance on imported seafood. Currently, Americans consume more than $24 billion in imported seafood annually, with approximately half estimated to be farmed overseas. By advancing domestic aquaculture, CIFARM aims to bolster national food security, create jobs and uplift coastal economies in complement to wild-capture fisheries.

The UH team will contribute to a broad range of research priorities. CIFARM researchers will investigate scientific solutions that can be leveraged for industry advancement. Key focus areas include engineering and technology development, artificial intelligence for aquaculture, environmental observations and forecasting, and marine aquaculture demonstration projects. The consortium will also conduct critical risk management, vulnerability analyses and seafood market research. The Hawaii team will also partner with USAPI researchers, including University of Guam Sea Grant and the in FSM to extend CIFARM’s reach throughout the Pacific.

“This partnership underscores the University of Ჹɲʻ’s vital role in advancing sustainable aquaculture systems that directly impact our global food supply,” said Norman Arancon, director of the UH Hilo College of Agriculture, Forestry and Natural Resource Management. “We have always championed practical, impactful science. Through CIFARM, our researchers and students will be at the forefront of a $13.5 million national effort, utilizing Ჹɲʻ’s unique seascape to drive economic growth, bolster food security, and train the next generation of leaders in sustainable marine aquaculture.”

鶹ý is uniquely positioned for this work. The state is already home to Blue Ocean Mariculture in Kona, currently the only offshore fish farm in the U.S., providing a vital real-world connection to the consortium’s demonstration and commercialization goals.

In addition to University of New Hampshire and UH, the network includes 鶹ý Sea Grant, New Hampshire Sea Grant, the University of Miami, Florida Sea Grant, the University of Southern Mississippi, the Mississippi-Alabama Sea Grant Consortium, Hubbs-Sea World Research Institute and California Sea Grant.

Three students from the are spending one year focusing on critical marine policy issues in Washington, D.C. representing the (鶹ý Sea Grant) as 2026 .

Gabrielle Ellis

completed her PhD in biological oceanography in spring 2025, for which she received the Mirikitani Outstanding Dissertation Award. Her dissertation provides baseline ecological descriptions of remote and unexplored habitats of the deep sea, and considers how resilient these habitats are to natural variation and human-induced impacts.

“If I have learned anything through my research as a deep-sea scientist, it is the power of transparent, long-term data in elevating science and protecting important ecosystems,” said Ellis. “I am so excited to witness this through NOAA’s Global Ocean Monitoring and Observing Program, and I am honored to be working with the international and multistakeholder network of the Arctic Research Program.”

Jonathan Rosen

began his career as a Peace Corps volunteer as a coastal resource manager, and continued this work in 鶹ý supporting the restoration of Hawaiian fishponds and monitoring endangered species in the remote atolls of Papahānaumokuākea. He earned his master’s degree in marine biology as a NSF Graduate Research Fellow studying the impacts of marine heatwaves on fish physiology.

“To me, this feels like a once in lifetime opportunity to expand my experiences and expertise by working alongside the U.S. Fish and Wildlife Ecological Services Headquarters,” Rosen said. “Through this fellowship I hope to apply my experience in conservation, research and communication towards the implementation of legislation on national conservation priorities, including the Endangered Species Act and Marine Mammal Protection Act.”

Sarah Woo

is currently a PhD candidate in the Natural Resources and Environmental Management Department at UH Mānoa focusing on collaborative community-based research, management and governance. Her graduate research is based in Kāneʻohe Bay, working alongside the Heʻeia National Estuarine Research Reserve and regional generational lawaiʻa (fishers), marine scientists who work in the Bay, and resource management agencies.

“I feel extremely grateful to have been selected to represent 鶹ý as a Knauss Legislative Fellow in Sen. Brian Schatz’s office focusing on topics such as oceans, climate, fisheries, and water, and assisting with appropriations and science legislation,” said Woo. “Growing up in the Pacific Northwest’s Washington, I never expected to live and work in Washington, D.C., but am excited for this new adventure to learn about the federal government so that I can come back home to 鶹ý after and apply what I have learned to support community needs.”

Paoa and family after 2026 spring commencement.

Growing up on Rapa Nui, Noah Paoa spent his summers camping by the shore, bodyboarding, and exploring the island’s landscape with his family. A pivotal moment occurred in 2010 when, at 15 years old, a massive earthquake in Chile triggered a tsunami warning for the island. Paoa watched the shoreline recede so far it seemed as if the ocean had never been there. This experience highlighted how closely life on an island is tied to the forces of the sea, eventually guiding him toward a historic academic milestone.

Graduating with the University of 鶹ý at Mānoa in May, Paoa earned a landmark achievement as the first Rapa Nui person to go through the Rapa Nui school system and earn a doctoral degree. While he is careful to honor those who paved the way, Paoa’s degree in from the UH Mānoa (SOEST) is significant personally and for his community.

“Earning this degree is an honor for me, but it is also the reflection of all the work that Rapa Nui people have done so that Rapa Nui students would have the tools to pursue advanced studies,” Paoa said. “I see myself as a testament and example for future Rapa Nui students and perhaps for students of other small island communities.”

Chip Fletcher, professor and dean of SOEST, served as Paoa’s advisor for both his master’s and doctoral degrees. Fletcher said Paoa brought an extraordinary combination of determination, discipline and insight to his graduate work.

“Noah has an incredible work ethic and a rare intuition for coastal science,” Fletcher said. “He has the ability to see both the physical processes shaping island shorelines and the deeper cultural meaning of what is at stake. His research reflects years of hard work, careful thinking, and a deep commitment to serving Rapa Nui and other island communities.”

His doctoral research addresses the , such as ceremonial sites, ancestral landscapes and sacred places.

“Most climate research focuses on impacts to infrastructure and ecosystems, but I wanted to show that coastal cultural heritage is just as vulnerable, and that losing these sites would be more than an archaeological loss, it could result in disruption to cultural identity and continuity,” Paoa said.

Cultural pride and responsibility

rapa nui

Growing up with a Rapa Nui father and a German mother who dedicated part of her life to preserving the Rapa Nui language, Paoa grew up surrounded by both cultural pride and a recognition of the responsibility that comes with preserving language, knowledge and identity. He felt a frustration with the island’s extractive academic past, where outside researchers often benefited their own careers without providing tangible benefits to the local people.

“My research provides new modeling tools and regional datasets to support heritage preservation and climate adaptation planning, but I’ve tried to be clear that what I have produced is to inform management and planning, and that decisions must ultimately be guided by descendant communities and grounded in their own cultural protocols,” Paoa shared.

By pursuing earth sciences, beginning as an undergraduate student at the University of Oregon, Paoa found a way to link geological processes to issues that affect his home island.

“I hope this work inspires future generations of Rapa Nui to pursue scientific paths of their own, helping ensure that research on our island increasingly reflects our own voices, perspectives, and priorities,” said Paoa. “This degree isn’t only mine, it belongs to everyone who made the path possible, and my responsibility now is to carry what I’ve learned back home and put it to use for Rapa Nui.”

To mark the formal launch of a year-long effort to assess climate vulnerability and build resilience across the Waiʻanae Moku, the Waiʻanae Readiness Review held its first community meeting on April 29, at Kamehameha Schools’ Kaiāulu Community Learning Center in Māʻili. The project is led by the University of 鶹ý at āԴDz’s (CRC), headed by Chip Fletcher, dean of the (SOEST), in partnership with the UH Mānoa Wildfire Research led by Clay Trauernicht, and the of the City and County of Honolulu.

“We are honored to stand with the people of Waiʻanae in this work,” said Fletcher. “Climate resilience is not something the University can define alone from the outside; it must be grown through pilina—with communities, government partners, agencies, and researchers working together in trust and shared kuleana (responsibility). The ʻike and lived experience of Waiʻanae families, farmers, practitioners, and leaders are essential to understanding the hazards facing the moku and identifying the actions that will protect people, place, and future generations. Guided by aloha ʻāina, this effort recognizes that caring for the land and ocean is inseparable from caring for one another.”

Identifying flood, wildfire hazards

CRC researcher Kayla Yamamoto presented on compound flooding and invited community members to share photographs and firsthand experiences with flooding events to help validate scientific models. Attendees also participated in open discussion, sharing the most pressing challenges and needs across the district.

The review is structured around two committees comprising community members, farmers, government officials, military installation representatives, technical experts, policymakers and non-profit organizations. The committees will meet six times over the course of the project, contributing their manaʻo (thought or idea) and expertise to guide the work.

CRC and the UH Wildfire team are developing climate projections scaled specifically to Waiʻanae, covering heat, precipitation/drought, compound flooding, coastal flooding and erosion, high wave run-up, groundwater inundation and wildfire. Given that wildfire risk is severe across the entire moku, the project’s focus is not on identifying where danger exists, but on determining what actions can be taken to address it.

More than 90 committee members, community members and project team representatives attended the meeting, which opened with a pule (blessing) led by Nohea Stevens. Presentations from Fletcher, Trauernicht, Captain White of Joint Base Pearl Harbor-Hickam and Susan Veazy of the Office of Local Defense and Community Cooperation outlined the origins of the project’s funding, the process it will follow, and the overarching goal of securing additional resources for priority projects in the moku (district).

An innovative University of 鶹ý research team is using trail cameras and artificial intelligence (AI) to better understand how much fog contributes water to native ecosystems and groundwater recharge. Led in part by Honolulu Community College Professor John DeLay, the project focuses on Mount Kaʻala, ʻ’s highest peak and an essential watershed.

“If we can keep the project going long enough, we might be able to detect a change in the lifting condensation level—affecting the extent of cloud and fog at the canopy level,” DeLay said.

Recharging the aquifer

Supported by the UH Office of Innovation and Commercialization, the system has achieved up to 93% accuracy in identifying fog conditions across different sites in both day and night conditions. This allows researchers to build long-term records of fog frequency and examine how moisture patterns vary.

“Not only is it really important for these ecosystems, which have fragile native species that need a lot of moisture and water, it’s also recharging out water budgets and our aquifer,” said Joel Nicolow, a UH Mānoa graduate research assistant in the School of Ocean and Earth Science and Technology.

Turning to AI

Historically, measuring this critical moisture required highly specialized personnel and expensive, complex equipment. The team turned to technology for a solution.

“We wanted to look at using cameras as a much more scalable, cost-effective approach,” explained researcher Dylan Giardana of the UH Mānoa Water Resources Research Center. “We use a machine learning model to classify all the images that we’re getting from these trail cameras.”

Their analysis shows that fog frequency jumps dramatically from about 10% at an elevation of 600 meters to 70% at the 1,200-meter summit. Understanding these patterns is essential as climate change and invasive species threaten natural watersheds. Long-term data may also help land managers in adapting conservation strategies.

Students, teachers, city officials and community members gathered on Earth Day 2026.

An effort to clean up the Ala Wai Canal led by the University of 鶹ý at Mānoa celebrated two meaningful milestones in April. The reached 300,000 Genki Balls, and the City and County of Honolulu proclaimed April 2026 as “Genki Ball Month.” This bioremediation initiative involves Genki Balls—mud balls containing billions of Effective Microorganisms® (EM)—that are tossed into one of the state’s most polluted waterways where they sink to the bottom of the canal to help break down the sludge.

More than 150 students from Kamehameha Schools’ Kapālama elementary campus, 鶹ý School for the Deaf & Blind, Pearl City Elementary School, and Leilehua High School joined the Earth Day celebration at the Diamond Head end of the Ala Wai Canal.

The proclamation, signed by Honolulu Mayor Rick Blangiardi and presented at the celebration, designated Genki Ball Month in “recognition of the many dedicated individuals and organizations collaborating on the Genki Ala Wai Project” and honored the “noble efforts to keep Honolulu’s waterways vibrant, safe and clean.”

7 years and 300,000 balls later

EM Technology has been successful in more than 100 countries worldwide over the past 30 years, inspiring Kenneth Kaneshiro, director of the Center for Conservation Research and Training in the at UH Mānoa, and others to initiate this effort in 2019. Kaneshiro and his team determined that deploying Genki Balls was an approach that could engage community members and begin to enhance the water quality in the Ala Wai Canal.

The project has truly been a community-based effort, with more than 100 schools and organizations and 21,100 volunteers contributing over the past seven years. Students and community members helped make Genki Balls and tossed them into the canal, all while learning about the place where they live, work, and play.

“What is most gratifying for me is to see how the kids can be influenced by the project and be inspired to go into STEM fields,” said Kaneshiro. “In one instance, a student from ʻIolani School discovered a new species of bacteria which she named and described and published in a scientific journal. Another student built a drone using 3D printing technologies to be able to collect water samples from the Ala Wai to bring back to the lab for analyses of water quality.”

bachman hall

The University of 鶹ý at āԴDz’s Bachman Hall earned Leadership in Energy and Environmental Design LEED Gold certification on April 22, exceeding the university’s standard sustainability target for major renovations. UH has the largest inventory of sustainable buildings in the state, with 28 buildings certified under the LEED program.

The certification recognizes the building’s performance in energy efficiency, renewable energy generation, water conservation and indoor environmental quality following its recent modernization. University policy calls for a minimum LEED Silver certification, making Bachman Hall’s rating a notable achievement for a historic campus facility.

bachman hall courtyard

Originally built in 1949 and designed by 鶹ý architect Vladimir Ossipoff, Bachman Hall is one of the most recognizable buildings on campus. It houses administrative offices, including the Office of the President and Board of Regents (BOR), and features two lobby murals by artist Jean Charlot.

“We are proud to be leaders in energy and environmental designs for our campus built environments,” said UH Office of Sustainability Director Miles Topping. “With this project, we have reduced our dependence on fossil fuel, conserved water, and preserved historical significance. We are committed to a sustainable future, and will continue to lead by example.”

Maintaining historic character

From 2021 to 2023, the renovation maintained much of the building’s original structure, reducing the need for new materials and limiting construction-related impacts. Design elements were updated to improve performance while maintaining the building’s historic character.

Energy-efficient lighting and a new air conditioning system reduce energy use by about 22%. A 47-kilowatt photovoltaic (PV) system further lowered consumption, bringing the building to roughly 45% of baseline energy use. Water efficiency improvements such as low-flow plumbing fixtures reduce water use by 37%, saving an estimated 56,661 gallons annually. Permanent water meters were installed to help monitor usage and identify future conservation opportunities.

Indoor environmental quality was addressed through the use of low-emitting materials, including paints, coatings and flooring, along with improved ventilation and occupant-controlled lighting and temperature systems. Original-style jalousie windows were replaced with energy-efficient double-pane windows that include operable awnings. A reflective roof and added landscaping help reduce heat absorption, while exterior lighting was designed to minimize light pollution.

The renovation also addressed long-standing maintenance issues, including damage caused by roof leaks linked to earlier mechanical installations. The building was fully updated inside, creating flexible office space for approximately 65 employees, six conference rooms and a 2,500-square-foot boardroom used for BOR meetings.

Available through August 10, the “” exhibit by ethnomusicology lecturer Benjamin Fairfield combines ecomusicology with place-based learning and encourages examination of consumptive habits.

“The idea of accepting a label of trash as worthless primes us to see things as having no further utility and value,” said Fairfield. “This project is getting us to challenge those labels and think, ‘Is it really worthless? Can’t it still have a voice, a utility, be part of our song and part of our creative process?’”

Crafted in the classroom

Many of the pieces were crafted in Fairfield’s class, a sustainability-focused course initially supported by the (CSEAS), where students repurpose found objects into Thai musical instruments. CSEAS has also supported outreach workshops for Kani ka ʻŌ貹.

Many of the pieces were crafted in Fairfield’s MUS311(M) Thai Ensemble class.

“The class is important as a course that uses an Indigenous approach to sustainable music-making by recycling found objects and promotes craftsmanship grounded in Southeast Asian studies,” said Teri Skillman, CSEAS associate director.

“I was thinking, how can we connect community and music in a participatory way that is also sustainability-oriented? That’s where MUS311(M) brought all of these things together,” said Fairfield. “When students take the class, I wanted to make sure that music isn’t this scary thing that you’re not allowed to do.”

Fairfield’s project is largely inspired by his research as a graduate student and his time as a Peace Corps volunteer in Chiang Mai, Thailand, where he lived in a village with the Indigenous Karen (Pgaz k’Nyau) people.

Fairfieldʻs instruments
The instruments are made from a variety of repurposed materials.

“There were these musical traditions that were very interactive, and everyone had a role to play, whether it was dancing and clapping or joining along in some sort of singing capacity. Music wasn’t a presentational sort of thing—it was more participatory,” said Fairfield.

Currently serving as affiliate faculty at the and CSEAS, Fairfield brings a sense of inclusivity and creativity into his teaching.

“We’re going to celebrate sustainability and connection to the āina, and also repurpose these things as is done in the tradition,” said Fairfield, “Working with these materials is a way to connect people on a personal level to these objects that we otherwise don’t give a second thought to.”

‘Everyone’s welcome’

The exhibit highlights community involvement every step of the way, from collaborative works with local elementary schools to musings from local poets and professors.

It’s never too late to grow in new directions. For Scott “Uncle Scotty” Garlough, earning an associate of Arts in Liberal Arts from Honolulu Community College is more than a degree—it’s planting seeds for the future.

Planting the first seed

Before enrolling at Honolulu CC, Garlough had built a life rooted in service. As operations manager at Hoʻoula ʻĀԲ, a 100-acre nature preserve in Kalihi Valley, he has spent years helping restore native forests and supporting community health.

“In healing the land, we understand we are healing the community,” he said.

Although education was not a part of his original plan, a turning point came through the Ola Niuhelewai Program and encouragement from Kahale Saito and Kalei at Honolulu CC.

What began as a few Hawaiian language classes eventually grew into a full academic path. Over time, Garlough transitioned into the Liberal Arts program while continuing to take Hawaiian studies courses that aligned with his cultural work.

“Coming to school is my way of planting seeds,” he said. “The seeds will sprout when the conditions are just right.”

Blooming beyond the classroom

At Honolulu CC, Garlough found more than a classroom—he found community.

“I’m surrounded by people that I love who love me,” Garlough shared. As a peer mentor at the Hawaiian Center, he supports fellow students while continuing to learn from them. He also maintained a 4.0 GPA, balancing academics with community leadership.

Despite initial hesitancy about returning to school, Garlough pushed forward.

“All the things—‘I’m too old,’ ‘I don’t know how to use a computer,’ but once you start, it’s not as scary as you think,” he said.

Back to the roots

Garlough’s path to college was shaped by hardship. His mother was incarcerated during his childhood and passed away when he was 13. He spent years navigating homelessness, addiction and trauma.

Reflecting back, he realizes he had people guiding him—his kupuna leading him toward the community college that has played such an important role in his family.

“It wasn’t until I felt love that I was able to transform myself,” Garlough said. “I listen to what my kupunas are telling me. I listen to the plants. They understand energy and come with good energy.”

The power of community

For Garlough, everything comes back to community.

“Healing a community takes a community,” he said. “We rely on communities in times of trouble, but we also should in prosperity.”

Through his work with organizations such as E Alu Pū and Mālama Loko Iʻa, he advocates for a Hawaiian cultural point of view. Everything he studied in the classroom has allowed him to give back to his community, from making hala sails to repairing the hale. Garlough also practices Uhau Humu Pōhaku, Hawaiian rock masonry, as well as fishing, lashing, and caring for fishponds.

Looking ahead

While earning his degree is a meaningful accomplishment, Garlough sees it as just the beginning.

“This is step one,” he said. “There are a lot of people out there with knowledge, but no pathway to share it. This gives me that opportunity.”

His ultimate goal is to continue planting the seed for others. He is passionate about helping people connect with themselves, their culture, and their community.

“Plant the seed,” Garlough advised. “Wait for it to grow.”

The University of 鶹ý at Mānoa has leveled up its commitment to a greener future, earning a (STARS) Silver rating from the Association for the Advancement of Sustainability in Higher Education. This achievement recognize is publicly available on the STARS website.

stars silver award

“Earning a STARS Silver rating is a testament to the incredible collaboration across our campus to integrate sustainability into everything we do—from the classroom to our physical facilities,” said UH Mānoa (ISR) Director Makena Coffman. “This framework not only celebrates our current successes in teaching and research but provides us with a clear roadmap to further reduce our environmental footprint and enhance resilience both for our campus and island community.”

STARS is a transparent, self-reporting framework for colleges and universities to measure their sustainability performance. The rating marks a significant step forward from previous benchmarks, aligning UH Mānoa with top-tier peer institutions dedicated to environmental stewardship.

The successful reporting process was a joint effort between ISR and the UH Office of Sustainability with essential contributions from a range of departments and offices across campus. By documenting data ranging from energy-efficient infrastructure to sustainability-focused curriculum, the university has established a clear baseline for future growth.

“In the process of compiling data for this year’s STARS Report, I probably sent over 50 emails to individuals and departments across campus,” said Elisabeth Earley, administrative officer at ISR. “Everyone I reached out to was so kind and helpful and I am very thankful for their support in the reporting process. This Silver rating could not have been achieved without the wonderful folks from all corners of UH Mānoa.”

The first cohort of the at the University of 鶹ý at Mānoa includes 14 students, seven of whom are supported through from the National Oceanic and Atmospheric Administration (NOAA), 鶹ý (DAR) and a 鶹ý-based philanthropic organization. Students and their UH advisors will work collaboratively with the sponsoring agencies and 鶹ý communities on their graduate research projects.

“It is really encouraging to see the significant support for this new program from the community and the state and federal agencies we partner with,” said Jeff Drazen, sustainable fisheries program graduate chair and oceanography professor in the UH Mānoa (SOEST). “Welcoming the first cohort of students is an exciting milestone, and having this level of community collaboration will really advance our goal of ensuring sustainable fisheries for people throughout the Pacific.”

The incoming students receiving fellowships are Kai Holdaway, Alexander Jemal, Ashley Meara, Kahakuhailoa Poepoe, Mackenzie Thielmann, Andrea Vega and Jake Zikan. Of the seven students, six will pursue master’s degrees, and one will pursue a doctoral degree; two are from 鶹ý, and five are from the U.S. continent.

Supported by one of two DAR Fellowships, Thielmann’s research will focus on finding “nursery” areas where young fish grow along Oʻahu’s coastlines to help protect future fish populations. By analyzing a large state dataset, Thielmann will identify where juvenile fish are most common and see if these “hotspots” match up with where legal-sized adult fish live. This project will use advanced science to ensure that culturally important reef fish remain abundant for local families and fishers. Further, this will help DAR create better fishing rules and habitat protections.

One of the four fellowships supported by the in Honolulu, awarded to Holdaway, will support building a computer model that predicts where the 鶹ý longline fishing fleet might shift to as ocean conditions and fishing laws change. By analyzing vessel data and interviewing fishers, Holdaway wants to understand how factors like earnings, weather, and mapping tools influence a captain’s decisions. Ultimately, this work seeks to balance catching target fish with avoiding protected species to ensure a healthier marine ecosystem.

The project was originally developed in a first-semester graduate design studio by architecture students Edwin Sun, Jayden Uowolo and Dylan Martos. Reimagining the traditional Hawaiian “place of shelter” as a contemporary civic space, the design adapted cross-laminated timber and glue-laminated timber systems for long-term performance in tropical marine environments.

“I’m incredibly grateful for the opportunity to present my team’s work at the International Mass Timber Conference and represent the School of Architecture,” said Uowolo. “This experience pushed me to think more deeply about how traditional Pacific Island ideas can shape contemporary design, while also connecting me with a global community of designers, builders and thinkers. I left with a stronger understanding of how culture, material systems and industry all connect in the making of architecture.”

Addressing coastal challenges

The project addressed coastal challenges by elevating the structure to mitigate projected sea-level rise, storm surges and salt exposure. It also incorporated climate-specific durability strategies such as marine-grade coatings, protected steel connections and rainscreen façades integrated with cross ventilation.

Supported by School of Architecture Dean Mo Zell and guided by professors Ben Parker and Ho Kyung Lee, the students’ research also explored using locally harvested softwoods to strengthen regional supply chains and reduce transportation-related carbon emissions.

“Opportunities like this are so valuable to students,” said Parker. “They give them early exposure to the critical topics professional architects are discussing, and provide chances to network and connect with firms as they plan their own future careers. These events also enrich the school and the profession, as the exchange helps everyone to integrate education and research with real-world concerns.”

Heavy rainfall pours over a steep tropical landscape in 鶹ý.

For decades, scientists have worked to improve predictions of El Niño-Southern Oscillation (ENSO), a climate powerhouse that can cause droughts, flooding, marine heatwaves and more around the world. Researchers from the University of 鶹ý at Mānoa a study showing that they can skillfully predict El Niño and La Niña 15 months ahead of time using only observations of the ocean surface temperature and height—no complex climate model needed.

“We found that it can predict El Niño and La Niña surprisingly well, with useful skill up to about 15 months ahead,” said Yuxin Wang, lead author of the study and postdoctoral researcher with the in the UH Mānoa (SOEST). “Accurately predicting ENSO more than a year in advance is important because it can provide early warning, allowing communities, governments and resource managers to take actions and make adaptations to reduce the potential impacts from El Niño and La Niña.”

“Our simpler, data-driven empirical climate model, built only from ocean observations related to two core climate memories known for over 50 years, achieves ENSO forecast skill comparable to, and in some cases better than, many of today’s more complex climate models and leading AI-based approaches,” added Wang.

Building on past discoveries

Klaus Wyrtki, a pioneering oceanographer at SOEST in the 1960s through 1990s, was the first to show that sea level changes can reveal heat build-up in the tropical Pacific, which led him to propose using tide gauge observations to predict El Niño. Klaus Hasselmann, a German oceanographer and Nobel laureate, showed that the ocean can retain a memory of past climate conditions through large-scale temperature patterns, including sea surface temperature patterns outside the tropical Pacific that can still influence ENSO.

Building on these two principles, the SOEST team developed the “Wyrtki-CSLIM,” short for Wyrtki CycloStationary Linear Inverse Model, a computer model to predict ENSO.

Predicting future ENSO

The Wyrtki-CSLIM currently predicts the development of a strong El Niño, more than 2°C warmer than normal over the equatorial eastern Pacific, toward the end of this year. This up-to-date is available online at the UH Sea Level Center.

“Our Wyrtki model is predicting a stronger El Niño than most of the other statistical models, and it is in line with the much more sophisticated dynamical models,” said Matthew Widlansky, study co-author and associate director of the UH Sea Level Center. “However, it is important to note that all models have uncertainties, and the climate impacts of each El Niño event are different.”

This new research also offers a clear direction for other ENSO forecasting systems.

These interdisciplinary projects allow students to gain specialized skills, earn academic credit and explore new career pathways through hands-on experience. They are part of the University of 鶹ý‘s Office of Indigenous Knowledge and Innovation, which has established several Indigenous Data Hubs (IDH).

In one vital project, students are partnering with the nonprofit I Ola Wailuanui to aid in the restoration of Malaehaʻakoa heiau. Using drone technology, interns created 3D models of the historical site, which are now being used to inform and guide restoration efforts.

“Building pilina (connection) with Malaehaʻakoa and listening to what its needs are for restoration and integration into modern-day functioning has been integral,” said Kauaʻi CC IDH Coordinator Kamalani Chock. “When we interact with the space, we treat the heiau as an ancestor that can help the community cultivate mana (power). What the process of mana cultivation means in the 21st century is what we’re meditating on.”

Digitizing artifacts

A second project involves students digitizing fragile artifacts at Kauaʻi CC’s Kikuchi Center. They are photographing from 360 degrees and transforming those images into a 3D model with an associated texture map, making them accessible for study and public engagement on the .

“I think it’s important to expand the scope of potential career pathways on the island,” Creative Media Program Coordinator Joseph Tremonti said.

“Projects like this allow students to develop skills that can be applied to cultural heritage work, archives, and museum studies—fields where access to fragile materials is often limited. This opens up exciting opportunities for our students.”

Chock, who also teaches agriculture and natural science courses through Nā Pua Noʻeau (a pre-K–college enrichment program), emphasized the importance of connecting education directly to community needs.

“I think the future of education must be holistic,” Chock said. “It can’t be siloed into singular disciplines. Instead, it should recognize how these fields intersect and work together in our communities—especially in ways that support community health and well-being.”

ADSC has reopened to serve 鶹ý’s ag community with modern services.

The University of 鶹ý at Mānoa (CTAHR) is reopening the (ADSC). Local farmers will once again have access to soil and plant testing here in 鶹ý at a reasonable cost, instead of sending samples to the U.S. continent.

The center’s reopening also allows CTAHR to offer free soil and plant testing through July 21, 2026 to farmers whose land and crops were affected by Kona low flooding in March and April.

person looking at computer screen
CTAHR is working to add heavy metal testing, animal health diagnostics, and food nutrient content analysis for food product labeling.

Every affected farmer can submit up to three free samples for each of the following services:

  • Soil nutrient analysis: To determine if essential minerals were leached.
  • Plant tissue nutrient analysis: To assess the current nutrient uptake and health of surviving crops.
  • Plant disease diagnostics: To identify plant pathogens/outbreaks that may impact crops following flooding.
  • Insect identification: To monitor for shifts in pest populations following the storms.

The ADSC will continue to provide soil and plant testing services at reasonable prices to farmers who were not affected by the floods.

“The reopening is a pivotal moment in CTAHR’s mission to support stakeholders and food security across the state,” said CTAHR Dean Parwinder Grewal. “Fortunately the timing of the reopening also means we can deliver more support to farmers recovering from the floods. We are providing these tests at no cost for the next three months to help our agricultural partners get back on their feet.”

ADSC has modern testing services with recommendations from local experts who know 鶹ý’s soils and climate.

ADSC has reopened with an improved customer experience, including online payments, rapid turnaround of results, and interpretation of results and recommendations by CTAHR experts,” Parwinder said.

Brian Miyamoto, executive director of the Hawaii Farm Bureau, noted, “The reopening of the ADSC, along with three months of free testing, comes at a crucial time and helps farmers move forward with recovery and replanting. CTAHR is truly stepping up for our farmers, and we appreciate their leadership and commitment to supporting Ჹɲʻ’s agricultural community during this critical time.”

CTAHR is working to further expand its services to include seed testing, heavy metal testing, animal health diagnostics and food nutrient content analysis for food product labeling. ADSC is also expanding its seed production capacity and will add clean seedling production, which are young plants that are free from germs or disease.

University of 鶹ý at Mānoa researchers revealed that Waikīkī is facing a fundamental shift in flood hazards as sea levels rise—transitioning from a flooding that is driven primarily by rainfall to events increasingly dominated by tidal processes. The team identified two key pathways that will become more significant with sea-level rise, both of which will increase public exposure to sewage-contaminated waters. The study was published in .

“Our findings make clear that current flood management strategies for Waikīkī are incomplete,” said Kayla Yamamoto, climate modeling analyst at the in the UH Mānoa (SOEST). “Most planning focuses on surface damage and economic loss from storms, but largely ignores the contamination dimension. Our results show that contaminated flooding will become more frequent, more extensive, and eventually a daily occurrence rather than a storm-driven one. There are currently no effective management strategies in place to address this.”

Simulating future scenarios

The team used an open-source, physics-based flood model to simulate how multiple flood sources interact in Waikīkī. The team used an advanced flood model that, unlike previous models, integrates all sources of flooding—rain, tides, underground water behavior, and storm drains—to provide a single, complete view of the hazard

“What we found is that during extreme rainfall like we’ve been experiencing, high tides and elevated water levels in the Ala Wai can combine to create conditions where contaminated water flows back into low-lying streets and sidewalks,” said Shellie Habel, study co-author and coastal geologist with the Coastal Research Collaborative and . “As sea level rises, it will take less extreme rainfall and tides to cause similar flooding in the future.”

The two key pathways they identified were: storm drain backflow, where polluted water from the Ala Wai Canal is forced into streets and public spaces in Waikīkī through drainage systems, and groundwater emergence, which brings sewage and other contaminants from aging and leaking sewage infrastructure to the surface.

The model simulations show that storm drain backflow is projected to occur even when there is no rainfall:

  • 1 foot of sea-level rise: Storm drain backflow occurs during extreme tides, even without rain.
  • 2 feet of sea-level rise: Storm drain backflow occurs during moderate daily tidal conditions.
  • 4 feet of sea-level rise: Groundwater emergence (bringing sewage to the surface) begins to occur without rain.

Researchers compared their model simulations against tide gauges, canal water level sensors, groundwater monitoring wells, and photographs of street-level flooding during three real recent storm events, including a major 50-year Kona storm in December 2021, a moderate storm in April 2023, and a five-year Kona storm in May 2024.

Implications for Waikīkī, beyond

The Ala Wai Canal is one of the most polluted waterways in 鶹ý, containing sewage, heavy metals and pathogens such as Vibrio and MRSA. Exposure to these waters is a documented risk, with MRSA infections linked to 鶹ý waters already contributing to an estimated 200 deaths per year in the state. Because Waikīkī is a primary economic engine where residents and visitors are in constant contact with coastal waters, the anticipated flooding represents a growing public health and environmental crisis.

Many coastal cities around the world rely on estuarine waterways to drain their stormwater, and face the same combination of aging infrastructure, rising seas and contaminated waters.

“Our modeling framework is transferable, and we hope this study serves as a wake-up call to modernize stormwater and wastewater infrastructure, integrate contamination risk into coastal flood planning, and build early warning systems before these thresholds are crossed,” Yamamoto said.

An invasive algae already well-established in the Northwestern Hawaiian Islands is raising concern among researchers as it threatens to spread into the main Hawaiian Islands. Scientists from the University of 鶹ý at Mānoa and the U.S. Fish and Wildlife Service (USFWS) have identified a potential ally in slowing its advance: sea turtles.

Hawaiian green sea turtles (honu) have been documented for the first time actively grazing on Chondria tumulosa, an aggressive invasive red alga that has spread rapidly across reefs among three of the northernmost atolls in Papahānaumokuākea Marine National Monument (PMNM).

The findings, recently published in the journal by researchers, suggest that honu may play a meaningful role in controlling this ecologically damaging species—while also potentially spreading it.

“After these exciting finds, our multi-partner effort to prevent this seaweed from taking hold in the Main Hawaiian Islands must include a plan to increase numbers of threatened, native green sea turtles, as well as ramping up efforts to identify all routes that could allow Chondria to spread to Oʻahu,” said Celia Smith, UH Mānoa‘s professor and senior author of the study.

Dangers of C. tumulosa

First detected at Manawai (Pearl and Hermes Atoll) in 2016, C. tumulosa has since expanded to more than 101 square kilometers of reef habitat (nearly the size of Kahoʻolawe), including Kuaihelani (Midway Atoll) in 2021 and Hōlanikū (Kure Atoll) in 2022. The alga forms dense mats more than 6 centimeters thick that can smother live coral and displace native reef species, making it one of the most pressing threats to the monument’s reef ecosystems.

Turtles take a bite

Native honu are acting as reef defenders by grazing on invasive algae that threaten Papahānaumokuākea coral.

Using a stationary GoPro camera deployed on a reef at Midway Atoll in June and July 2025, the research team captured approximately 50 minutes of footage showing three honu grazing on C. tumulosa mats. One female took up to 18 bites in a 95-second burst, leaving disruptions 5–15 cm in diameter across the algal canopy—substantially larger than what urchins or fish could achieve. A complementary necropsy of a stranded adult female confirmed C. tumulosa fragments throughout her digestive tract, accounting for roughly 25% of the material in her esophagus and crop.

“These turtles are consuming a meaningful amount of this alga in a single foraging session,” said Tammy Summers, USFWS staff biologist and co-author of the study. “It’s exciting because it points to honu as a native megaherbivore with the potential to suppress C. tumulosa biomass—but it also raises important questions about whether fragments excreted during their migrations between atolls could accelerate the alga’s spread.”

The findings carry immediate management implications. Because 96% of Hawaiian green sea turtles nesting occurs at Lalo (French Frigate Shoals) before individuals disperse to foraging grounds across the archipelago, the authors recommend eDNA monitoring at Lalo to track potential spread of C. tumulosa beyond its known range.

The study was a collaboration between UH Mānoa‘s School of Life Sciences and USFWS Midway Atoll National Wildlife Refuge, and was funded by USFWS Invasive Species Strike Team funds through a cooperative agreement with UH Mānoa. Smith leads the Limu Lab at UH Mānoa, where research on C. tumulosa physiology, distribution and ecology has been ongoing for several years. Other authors on the paper are Caroline Pott from USFWS and Angela Richards Donà from the School of Life Sciences.
