A cohort of 10 University of 鶹ý at Mānoa undergraduates was selected to participate in the inaugural LUNADS—Lunar Undergraduate/graduate missioN Architecture Design Seminar—a competitive national program run by the Johns Hopkins Applied Physics Laboratory (APL) under NASA to engage university students in lunar science and NASA-style mission design.

The students are engaged in the Space System Science and Technology program undergraduate minors, either the minor in Earth and Planetary Exploration Technology or the minor in Human Space Flight Technology, administered by the (HIGP) in the UH Mānoa (SOEST).

Students in the HIGP programs will extend their work with this new opportunity.

“This program gives our undergraduate students direct access to NASA-style mission design alongside some of the best planetary scientists and engineers in the country—an experience that grows directly from our Earth and Planetary Exploration Technology and Human Space Flight Technology programs and reflects HIGP’s long-standing commitment to preparing the next generation of space scientists and engineers from 鶹ý,” said Peter Englert, HIGP professor and LUNADS faculty lead and program coordinator.

Designing a lunar mission concept

One of only four university cohorts chosen nationally, the UH Mānoa students will participate in the program throughout the 2026–2027 academic year. The program includes a Lunar Science Seminar Series, followed by a 10-week Mission Design Seminar in spring 2027 in which they work directly with APL scientists and engineers to design an actual lunar mission concept—the team chooses the science question and builds the mission. The completed mission architecture will be published on Zenodo, an open-access repository, with all student participants listed as co-authors.

The students bring diverse academic backgrounds, with majors spanning mechanical engineering (aerospace concentration), astrophysics and kinesiology and rehabilitation science. HIGP researchers Paul Lucey (lunar remote sensing), Matt Siegler (lunar thermal science and volatiles, such as water, carbon dioxide, and other gases) and Shuai Li (lunar water ice detection) will all serve as faculty advisors.

“The knowledge, skills and hands-on experiences ahead for these students make LUNADS participation a direct and meaningful extension of their academic work within HIGP and UH Mānoa programs,” Englert said. “I look forward to seeing where they take this opportunity.”

Yuqin Wang

World-leading tropical meteorologist Yuqing Wang, a professor in the and researcher with the in the University of 鶹ý at Mānoa School of Ocean and Earth Science and Technology (SOEST), was as a Fellow by the Asia Oceania Geosciences Society (AOGS).

Wang’s pioneering research has profoundly advanced understanding of tropical cyclone dynamics, prediction and climate impacts. His work has focused on two main areas of research: understanding the physics of extreme storms including hurricanes and typhoons and building computer models used to predict them and study climate change.

Fellows of the AOGS are selected in recognition of their sustained and distinguished contributions to geosciences in the Asia Oceania region and beyond. Wang will receive the award at the later this summer in Japan.

Wang’s landmark contributions

Wang’s contributions include the discovery of dynamics in the development and breakdown of tropical cyclone eyewalls, the ring of destructive winds surrounding the calm eye of a storm. He has also made fundamental advances in understanding the controls of tropical storm structure and intensity. His theories and models have been used to interpret environmental influences on tropical cyclones, explain long-term variability, and improve physical understanding relevant to tropical cyclone intensity forecasting.

Further, Wang has made major contributions to numerical atmospheric modeling. These models accurately simulated complex dynamics near the ocean surface and of clouds in the atmosphere. Some were so successful that they are incorporated into the community Weather Research and Forecasting model and have been widely adopted by the research and forecasting communities.

Beyond storm-scale research, Wang’s group has advanced regional and global climate modeling, cloud–radiation interaction studies, and created accurate models to assess Pacific Island climates. This research helps to produce influential assessments of the impacts of global warming on tropical cyclone activity in the western North Pacific.

Wang joined SOEST in 2000 and has published more than 300 publications during his 26 years of teaching and research at 鶹ýԴDz.

In a rapid response to one of the largest tectonic events to shake 鶹ý in decades, scientists from the University of 鶹ý at āԴDz’s have deployed a network of temporary seismic sensors across the west flank of Maunaloa on 鶹ý Island.

“Capturing the aftershock sequence and seismic structure at close range offers a rare opportunity to better understand the fault geometry and seismic hazards across the Hawaiian Islands,” said Sin-Mei Wu, assistant professor in the UH Mānoa (SOEST), who leads the initiative.

The emergency mobilization followed a powerful magnitude 6.0 earthquake near Hōnaunau-Nāpōʻopoʻo on May 22. Striking at a depth of 22 kilometers, the fault movement triggered a large earthquake that has been followed by an ongoing sequence of aftershocks (including a magnitude 4.0). The initial quake prompted public engagement with more than 7,000 residents across the state submitting U.S. Geological Survey “Did You Feel It?” reports—the for any 鶹ý earthquake.

Deploying from ma kai to ma uka

Unlike typical shallow earthquakes tied to the movement of volcanic magma, this deep event was driven by plate flexure—the sheer weight of the massive Hawaiian volcanoes bending the underlying oceanic Pacific Plate. While these flexure earthquakes represent a significant seismic hazard, they are notoriously difficult to study because they frequently originate offshore, far from land-based monitoring networks.

The May 22 event provided a rare opportunity to better understand these hazardous processes, as the epicenter was on land, enabling the deployment of a temporary seismic array to capture detailed aftershock activity. With funding from the SOEST Dean’s Office and sensors from the NSF EarthScope Consortium, Wu and Pablo Urra Tapia and Ian Wynn, two SOEST Earth sciences graduate students, rushed to 鶹ý Island for a three-day field campaign.

“It was definitely an all hands on deck to try to get this off the ground as quickly as possible,” said Helen Janiszewski, assistant professor of Earth sciences who supported planning and will focus on data collection and analysis for the project. Similarly, Thomas Lee, assistant professor in the UH Hilo Department of Geology helped to coordinate logistics, and will work with undergraduate students in comparing this event to the 2006 Kīholo Bay earthquake and other historical events.

The team also received essential assistance from Kamehameha Schools, Hakalau Forest National Wildlife Refuge and Puʻuhonua O Honaunau National Historical Park.

“Their help allowed us to deploy 30 seismic sensors from ma kai to ma uka, covering mainshock and aftershock regions,” said Wu. “Our community partners are critical collaborators, as they have enabled us to receive permits and land-access so we could deploy the sensor in time to capture the aftershocks.”

Facing grueling off-road conditions across 80% of the terrain, the team successfully placed sensors at elevations ranging from just 100 feet near the coastline up to 7,500 feet into the high-altitude, old lava fields of Maunaloa.

鶹ý’s seismic hazards

Completed on June 5, the high-resolution array is now actively recording continuous ground vibrations. It has already caught a steady stream of active aftershocks between magnitudes 1 to 3, and the team expects the enhanced local network will catch hundreds of micro-earthquakes of magnitudes 0 to 1 that are invisible to standard infrastructure.

“The enhanced seismic network can detect and characterize those smaller earthquakes that carry equally important information about the earthquake source region,” said Wu. “This project exemplifies SOEST’s commitment to rapid hazard response and we expect to gather data that will benefit both scientific research and seismic hazard assessment in 鶹ý.”

The research team will collect the seismic data and then begin to analyze their trove of information in August.

When recent severe storms knocked out power and caused destructive flooding across Oʻahu, many community members were underprepared. Enter Watson Culley, an Oʻahu middle school student who spends most of his free time playing basketball. Inspired by a recent service-learning class that emphasized the power of being community-minded, Watson wanted to turn the classroom ideas into concrete action.

The spark fully ignited after he volunteered to help distribute Federal Emergency Management Agency (FEMA) emergency food rations to students at the UH Mānoa (SOEST). Interacting with the students, he noticed how many people lacked the most basic supplies to be prepared for a crisis.

Oceanography graduate student Tyra Arends received a Give-and-Go box from Watson Culley.

“In my service-learning class, we learned about the benefits of these kinds of projects,” Watson said. “We learned that if everyone helps just a little, it can make a big difference.”

Watson drafted a list of essential supplies, calculated expenses and developed a plan to make it happen. Included in the compact, waterproof kits would be a Mylar blanket, water purification tablets, matches, a whistle, granola bars, a basic first aid kit, an emergency contacts card, batteries and a headlamp.

“The name Give-and-Go Emergency Box was inspired by my love for basketball,” Watson said, referring to a classic basketball play wherein two teammates work together to make an open shot or layup.

Immediate impact

With the help of his family and monetary donations from his neighbors, Watson launched the “Give-and-Go” Emergency Box project. Thirty SOEST undergraduate and graduate students recently received the first round of Give-and-Go boxes at no cost. The impact was immediate for Watson and the student recipients.

For Watson, the project gave him experience in planning and executing his vision. It also helped him build community with the people in his neighborhood and at UH Mānoa. And, he shared, “it felt good to spread aloha.”

In a follow-up survey, 100% of student recipients rated the boxes as a 5 out of 5 for usefulness, noting that the kits made them feel significantly more prepared. Furthermore, 97.5% of respondents noted that the boxes would help safeguard others in their households.

For cash-strapped students, the kits filled critical gaps. One student shared that they didn’t have spare batteries or blankets before receiving the box. While another noted, “All of our appliances in our apartment are electric, and so when we first went through a series of blackouts we had no battery lights or candles. So the headlights that were included were so, so helpful!”

Rare, deep-sea goblin shark observed in natural habitat /news/2026/06/15/goblin-shark/ Tue, 16 Jun 2026 00:22:47 +0000 /news/?p=236030 The first published live observations of the rare goblin shark (Mitsukurina owstoni) in its natural deep ocean habitat were reported by a UH Mānoa-led team of oceanographers.

The of the rare goblin shark (Mitsukurina owstoni) in its natural deep ocean habitat were reported by a University of 鶹ý at Mānoa-led team of oceanographers. In the past, goblin sharks were only filmed and reported alive after being hooked on a fishing line and hauled to the surface, where divers could observe them and where they soon died. The study documents two live observations of one of the most elusive but iconic sharks on the planet—one at a seamount near Jarvis Island and another on the slope of the Tonga Trench.

Goblin sharks are sometimes referred to as “living fossils,” as they are the only living representative of their family, a lineage of sharks that is nearly 125 million years old. These observations extend their known depth range and geographic range significantly.

“Seeing the most iconic of all the deep-sea sharks alive and looking healthy in its natural habitat is a unique honour,” said Aaron Judah, lead author of the paper and doctoral candidate working in the and (DARC) in the at the UH Mānoa . “I was also very surprised about how deep this species was found. The observation from the slope of the Tonga Trench is nearly 700 meters deeper than this species was known to live.”

Judah noted this observation extends the depth record for the entire order of Lamniformes, the mackerel sharks, which include other notable species such as the white shark, basking shark and mako shark. Previously, the goblin shark was only known to inhabit narrow areas off the coast of the western U.S., Australia, and Japan in the Pacific Ocean, and narrow regions in the Atlantic and Indian Oceans. The findings significantly extend the geographic range, with both sightings being made in the Central Pacific.

Treasure hunting in the archives

In 2025, Judah spoke with colleagues at DARC who mentioned there had been a potential goblin shark sighting during a 2019 expedition aboard the exploration vessel (E/V) Nautilus exploring deep-sea ecosystems near Kingman Reef, Palmyra Atoll and Jarvis Island within the Pacific Remote Islands Marine National Monument.

“I was shocked to hear this because this species was not to be known to be in the Central Pacific,” said Judah.

The footage on that cruise was captured using a camera system on the remotely-operated vehicle Hercules, publicly archived for global access, and later annotated by colleagues at DARC. Judah combed through this archive and discovered that the team had documented a goblin shark during the livestreamed dive on an unnamed seamount northwest of Jarvis Island.

The second observation was made during an expedition to the Tonga Trench which took place in 2024 aboard the research vessel (R/V) Dagon as part of the Inkfish Open Ocean Expedition led by scientists from the , when a baited camera on a bottom lander captured footage of a goblin shark in their natural habitat.

“The Goblin Shark is one of these deep-sea charismatic animals that I never thought we’d see alive, and then to do so was amazing, but to then learn that colleagues in Hawai’i also saw one was just incredible,” said Alan Jamieson, professor and founding director at Minderoo-UWA Deep-Sea Research Center and study co-author who documented the 2024 sighting.

“It is really important that we still perform natural history work,” Judah said. “New discoveries like this demonstrate that there is still so much to explore in our deep ocean home. Given the newly-expanded geographic range of the goblin shark, this species can be included in regional management and a nation’s biodiversity list, whereas, beforehand we didnʻt know it was even there!”

Tectonic stress along the San Andreas and San Jacinto fault systems in Southern California has now reached, and in some places exceeded, the highest levels seen in the past 1,000 years, according to research led by Earth scientists at the University of 鶹ý at Mānoa. The study, published in , has direct implications for seismic hazard assessments in one of the most densely populated and infrastructure-critical corridors in the U.S.

“Our results show that stress levels on multiple fault segments are now at or above the highest values seen in the past millennium and that the region may be capable of a large through-going rupture involving both fault systems,” said lead author Liliane Burkhard, research affiliate in the at the UH Mānoa and scientist at the University of Bern, Switzerland. “We also found that Cajon Pass may act as an ‘earthquake gate’: sometimes blocking large ruptures from crossing between the faults, and sometimes allowing them to pass through and involve both systems in a single event.”

1,000 years of earthquake history

The researchers built a physics-based computer model that simulates how stress builds up and releases along the southern San Andreas and San Jacinto fault systems, including at Cajon Pass, which is a critical junction between the two fault systems. They fed the model a 1,000-year record of earthquake history of the region reconstructed from geological evidence such as radiocarbon dating of displaced sediments and tree-ring records. By running this simulation forward to the present day, they estimated how much stress has built up.

“The conditions that determine whether the ‘earthquake gate’ at Cajon Pass opens or stays closed appear to be related to how closely the stress levels on the two fault systems are aligned with each other at the time of rupture,” Burkhard said. “Right now, with stress at historically high levels across the region and more than 160 years elapsed since the last major rupture, the system is in a critically loaded state.”

Results from this study suggest that the stress that would normally be released in large earthquakes has continued to accumulate and is now at unprecedented levels. Perhaps most importantly, the study showed that Cajon Pass could facilitate a joint rupture of both the San Andreas and San Jacinto faults simultaneously, which is a scenario that could be significantly more damaging than a single-fault event, and one that affects densely populated areas including Los Angeles, San Bernardino, Riverside and the Coachella Valley.

Improving earthquake hazard research

This kind of physics-based stress modeling can help refine seismic hazard assessments and inform infrastructure planning, emergency preparedness, and building codes in the region. Additionally, the modeling framework used in this study is applicable to other complex fault junctions globally, so the researchers are interested in developing it as a reusable tool for multi-fault hazard assessments.

“This is not a prediction of when an earthquake will happen,” Burkhard said. “However, studies like this are important contributions to national and global earthquake hazard research in that we are using rigorous, quantitative science to better understand the risk facing millions of people. What we can say is that the system is critically stressed, and that physics-based models like this one give us a clearer picture of the range of scenarios we should be prepared for. That information matters for hazard assessments, infrastructure planning, and emergency preparedness.”

Additional authors of the study include researchers from Northern Arizona University, University of Bern, U.S. Geological Survey and University of California, San Diego.

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.

“I congratulate all our spring graduates on successfully completing their required faculty-mentored thesis experience,” said Michael Guidry, chair of the GES Program. “As with all our GES graduates and their thesis work, Makana’s and Micah’s findings demonstrate how the research efforts of UH Mānoa undergraduates provide new insights and solutions to important issues and train the next generation of problem solvers.”

Makana Andrade

Andrade was born and raised on Oʻahu, 鶹ý. During his second year of transfer to UH Mānoa, he started working on his thesis with his mentor, Travis Idol, associate professor in the in the UH Mānoa . His thesis focused on the response of Acacia koaia, a tree endemic to 鶹ý, to nursery practices done on similar species, specifically Acacia koa. Andrade’s study examined koaiʻa’s growth patterns from seed to seedling to determine its preferred soil type, nutrient uptake, and watering requirements, in an effort to ensure they are readily available for population revitalization.

After graduation, Andrade hopes to continue pursuing his passion for the conservation of Hawaiian endemic species and working in the wilderness.

Micah Soriano

As a GES student with a passion for chemistry, Soriano reached out to SOEST oceanography professor Nick Hawco and joined the Hawco Lab the summer after his sophomore year. Since then, Soriano has helped with various projects, gaining valuable experience. For his senior research thesis, Soriano explored how vitamin B12 availability in the Southern Ocean limits how effectively diatoms, a type of phytoplankton, can process and use essential metals for growth.

After graduation, he plans to work for a year or two before continuing his academic studies.

Ჹɲʻ’s endangered false killer whales show signs of nutritional stress /news/2026/06/05/false-killer-whales-nutrition/ Fri, 05 Jun 2026 20:12:19 +0000 /news/?p=235637 A seven-year study has revealed alarming fluctuations in the health of Ჹɲʻ’s endangered insular false killer whales.

Some of Ჹɲʻ’s endangered false killer whales are rapidly losing weight, a warning sign that warming oceans and limited prey may be pushing one of the nation’s smallest whale populations closer to extinction, according to research by a team including scientists from the University of 鶹ý at Mānoa.

The findings provide the first quantitative evidence that nutritional stress and competition with fisheries may be accelerating the decline of this iconic population, which now numbers fewer than 140 individuals.

The research—a partnership between the (PWF), (MMRP) at UH Mānoa and —utilized high-resolution drone photogrammetry to track 68 whales (roughly half the remaining population) between 2019 and 2025.

Rapid declines and climate links

The study documented extreme physiological shifts, including one individual that lost an estimated 28% of its body mass—approximately 500 pounds—over a 10-week period. Researchers also found that the population’s overall Body Condition Index hit a record low in 2020. This decline coincided with a severe marine heatwave and the largest single-year population drop in recent history, suggesting that rising ocean temperatures could be impacting the whales’ ability to maintain necessary energy reserves.

“This study is a critical step in understanding whether prey limitation is driving the extinction risk for these whales,” explains Jens Currie, Chief Scientist at PWF, PhD candidate in the , and lead author of the study. “Our findings suggest that many individuals are living on a thin metabolic margin. We are now examining how competition with fisheries for high-energy prey like ‘ahi (yellowfin tuna) and mahimahi may be forcing these whales into a state of chronic nutritional stress.”

Mapping health across the archipelago

The research highlights that health is not distributed equally across the population. Whales in “Cluster 1,” known for traveling broad distances across the islands, showed significant variability in their physical condition. This suggests that the high energetic cost of moving long distances to find prey may be taking a heavier physical toll on certain social groups than others.

To ensure the highest level of accuracy, the research team validated their drone measurements against 3D scans of whales in human care at the Okinawa Churashima Foundation in Japan. This calibration provided the foundational data needed to convert aerial images into precise weight and volume estimates, confirming that the study’s measurements are accurate to within 3%.

“This level of precision allows us to pinpoint exactly when and where these whales are struggling, which is key for directing conservation efforts,” said Lars Bejder, MMRP director, title=”鶹ý Institute of Marine Biology”>HIMB professor, and co-author of the study.

The whales found in 鶹ý are a distinct, island-resident population adapted to the region’s coastal ecosystems and dependent on these waters for survival. They represent one of the smallest and most endangered whale populations in the United States, where the loss of even a few animals can have consequences for the entire population.

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).

The visit also included tours of two of UH Mānoa’s world-class research facilities: the (HSFL) and the (HIMB).

Kent was joined by Deputy Under Secretary James Bergeron, Special Assistant Cristian Clementi, Press Secretary for Higher Education Ellen Keast and Special Advisor Ethan Good.

Hensel welcomed the delegation with Debora Halbert, UH vice president for academic strategy; Chad Walton, UH interim vice president for research and innovation; Vassilis Syrmos, UH Mānoa interim provost; and Rob Wright, UH Mānoa interim vice provost for research and scholarship.

“We are trying together to make it the best environment possible for student achievement, and wherever we can partner to make that happen, we are happy to do so,” said Hensel. “Higher education, K–12, it all works together as an ecosystem, and when we collaborate and strengthen those connections, we succeed for our students. When it becomes fragmented, we lose the ability to reach their full potential.”

Showcasing innovation and student success

During the visit, university leaders provided an overview of the UH system, including student success efforts, workforce development initiatives, affordability, financial aid, enrollment trends and the university’s role as 鶹ý’s sole public provider of higher education. The discussion also highlighted UH’s research enterprise, which secured a record $734 million in extramural awards in fiscal year 2025, including more than $60 million from the U.S. Department of Education across 115 projects.

“We’re very excited to be here talking with President Hensel and her leadership team about the opportunities for higher education in 鶹ý and how they are so distinct from those on the mainland,” said Kent. “We still see some of the same challenges here in 鶹ý with the affordability of higher education, but the president and her leadership team are focused on how to get costs down, how to ensure outcomes translate into earnings and workforce pathways, and how to work with local communities and employers to make sure students are getting good-paying jobs.”

The delegation toured the HSFL clean room at UH ԴDz, where university researchers design and build SmallSats for science and educational missions. The tour was led by Wright and Lance Yoneshige, integration and launch specialist engineer. The clean room is primarily used for the integration, assembly and testing of satellites.

Federal officials also traveled to the HIMB on Moku o Loʻe (Coconut Island) in Kāneʻohe Bay for a tour led by HIMB Director Megan Donahue. An organized research unit of UH ԴDz, HIMB is internationally recognized for research on coral reefs, marine ecosystems, climate resilience and ocean health.

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.”

For her research on fungi that can degrade plastic and sunscreen, Vera Wang, a senior at Kaiser High School, won in multiple categories at the for her research conducted in ’s lab at the University of 鶹ý at Mānoa. Wang’s project earned 1st place Best in Category (Microbiology), 3rd place Best in Fair, a special award from the Friends of Hanauma Bay, a special award from Association for Women Geoscientist, and a scholarship award from the McInerny Foundation. She also qualified for the International Science & Engineering Fair, which will take place in May in Phoenix, Arizona.

Wang works in Anthony Amend’s lab in the Pacific Biosciences Research Center.

“I am so grateful to have been given the opportunity to pursue my project in the Amend Lab,” said Wang, who worked closely with Kaylee Christensen, a graduate student in the Marine Biology Graduate Program. “My research would have never, ever, been possible without Anthony and Kaylee. This project has been part of a much longer journey, so having it recognized feels both surreal and deeply rewarding.”

“This work was made possible because of Vera’s vision, and it gives me such optimism about the future of science in 鶹ý,” said Amend, who is based in the at (SOEST). “Her success is a testament to our public school system which is doing a wonderful job supporting and training our next generation of students. I can’t wait to see what discoveries she makes in college!”

Coconuts, fungus vs. plastic, sunscreen

During her sophomore year, Wang designed and built an ocean filter that removed sunscreen and microplastics from the surface water that was inspired by traditional Polynesian weaving while incorporating modern environmental science. It was not only scientifically effective, but—made entirely from coconut byproducts—also environmentally responsible across its full life cycle. But Wang realized that removing the pollutants from water is only part of the problem. The next challenge she considered was how to dispose of them responsibly.

“I learned that the pore structure of coconut fiber supports the movement of air and water, which can create a favorable environment for microbes,” Wang said. “That led me to wonder whether coconut husk could do more than physically capture pollutants. So this year, my research at the Amend Lab began exploring the fungal communities living in coconut husks and studying their growth and degradation abilities on sunscreen and plastic media.”

They discovered that fungi found naturally on coconut husks can biodegrade (decompose) sunscreen and plastic and that a tannin compound can be used to identify sunscreen- and plastic-degrading fungi. Christensen shared that the tannins present in the fibers might be encouraging growth of these complex degraders. Additionally, their genetic testing showed that some of the fungal species did not have a match to anything in the world’s largest reference database of known genes and genomes, indicating that these may be previously uncharacterized species.

University of 鶹ý at Mānoa graduating senior Emily Josefina Velasquez had full-ride scholarship offers closer to home. Instead, Velasquez, who came to 鶹ý from Mozambique, chose UH Mānoa for its culture of environmental stewardship and community-centered science.

Among the more than 2,500 graduates in UH Mānoa’s spring 2026 commencement ceremonies, Velasquez may have traveled the farthest to reach the islands. Her journey from Mozambique in southeastern Africa to 鶹ý spans approximately 12,000 miles, one of the longest possible distances between two points on Earth. She said 鶹ý immediately felt familiar in their connections between environment, culture and community.

“I wanted to study somewhere where the love and the passion for the environment and environmental science wasn’t separate from everyday life and kind of just ingrained within the culture,” she said.

Her family is expected to travel to 鶹ý to attend commencement. Velasquez said she told them that they didn’t have to make the trip, but they insisted on coming, and she said she is excited to welcome them to 鶹ý to watch her graduate.

Raised across continents

A major in the , Velasquez was born in California before moving with her family to Nigeria at 3 months old. She later lived in Ecuador and Mozambique as her father worked on international shipping port development projects.

Before arriving in 鶹ý, Velasquez said she was searching for a university where science extended beyond the classroom. It was her high school English teacher at the American International School of Mozambique—where she graduated as the valedictorian—who told her what he knew about UH ԴDz.

“You can take a biology class, and they’ll teach you the same things, but it’s all about how it’s implemented,” she said. “I wanted to learn not only how the ecosystem works, but how it’s integrated within the community and the culture.”

‘I had a purpose being here’

She said Ჹɲʻ’s emphasis on environmental stewardship reminded her of the collectivist cultures she experienced growing up in Mozambique and Ecuador.

“I felt like the Hawaiian epistemology and the way the culture just so resembles what I grew up in,” she said.

At UH ԴDz, Velasquez immersed herself in research opportunities across multiple disciplines. Her work has included invasive algae research in the Galápagos Islands, invasive species studies at and marine carbon dioxide removal research through the . She has received funding and a scholarship through to present research on invasive species in Portugal.

“I was just extremely busy doing things,” Velasquez said. “Joining the sailing team and joining organizations and work definitely made it not feel like I was so far away from home, but that all the work I was doing here was meaningful and like I had a purpose being here.”

Finding community in 鶹ý

U H graduates

Velasquez said the transition to 鶹ý was made easier through friendships she built at UH ԴDz, especially with her roommate, an international student from Switzerland and Brazil.

“Knowing that both our families are on the complete opposite side of the world, we were always there for each other,” she said.

Although she is graduating a year early, Velasquez said she plans to take time to reconnect with family and community in Mozambique before pursuing graduate school.

I haven’t gone back home for almost the entire time I’ve been here. I need to return, not just to my family but to my other community, to reconnect and reflect on why I chose this path and where everything I’ve learned can do the most good. Honestly, home is a complicated word for me since it’s not just where my family is but where I can show up, contribute, belong and wherever my curiosity takes me next.

Looking back on her time at UH ԴDz, Velasquez said the university shaped both her scientific perspective and her understanding of responsibility as a researcher.

“It definitely has shaped me to become the kind of scientist that I want to become,” she said. “It showed me that science and cultural knowledge do not exist separately.”

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.

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.

University of 鶹ý at Mānoa professor David Ho was selected as a lead author for the on carbon dioxide removal (CDR) and carbon capture, utilization and storage (CCUS). The report will give guidance to countries regarding how to estimate and report the emissions they manage through those methods as part of their national greenhouse gas inventories.

CDR and CCUS are tools to help countries achieve their emissions and climate targets, and the diversity of approaches to remove and capture carbon dioxide from the atmosphere are growing fast.

“However, countries currently lack consistent, scientifically rigorous guidance on estimating and reporting the emissions they manage through these technologies in their national greenhouse gas inventories,” said Ho. “Without that, it’s very difficult to hold anyone accountable or to determine whether CDR and CCUS are actually delivering on their promises. This methodology report is about building the foundation to get the accounting right so that progress in CDR and CCUS is real and verifiable.”

The current federal administration withdrew the U.S. from the IPCC process earlier this year, creating a gap in U.S. expert representation in the IPCC. An observer organization nominated Ho so that U.S.-based expertise could still contribute to this report.

“The IPCC has brought together lead authors from a wide range of disciplines and geographies, and the conversations are already substantive and rigorous,” Ho said. “There’s a real shared sense that this report matters, that it will shape how governments think about CDR and CCUS for years to come. It’s a significant commitment, but one I think is genuinely worth making.”

The first lead author meeting was held in Rome, Italy, in April. More than 150 experts, selected by the IPCC Task Force Bureau, are participating in the writing process.
