In late June, Kealaokalani Kaaloa and Thor Donola traveled to Nome, Alaska, as Hawaiʻi Audubon Society Kōlea Quest scholarship recipients.

“One thing that was really put into perspective for me is just how little we truly know about bird species,” said Kaaloa, a biology major. “Just the concept of the kōlea migrating to Alaska was too vast to really grasp how incredible the journey really is, until you put yourself on a plane and actually go to Alaska.”

Over five days, the group observed at least 15 kōlea, documented 70 Arctic bird species and explored the Bering Strait region. The Kapiʻolani CC students also shared their Hawaiʻi-based research with fellow participants.

Recommended by Kapiʻolani CC professor of biology and ecology Wendy Kuntz, who organized and led the trip, Kaaloa and Donola became the college’s eighth and ninth participants in the Kōlea Quest program since 2023.

“Observing kōlea on their summer breeding grounds and experiencing the tundra helps students to connect the questions we explore together at Kapiʻolani CC to the broader story of migration and conservation, and to the biological and cultural ties between Hawaiʻi and Alaska,” Kuntz said.

Sharing culture

At a Katirvik Cultural Center gathering, Kaaloa offered traditional chants, including Kū Ka ʻ, “Transformed Waterworn Stones,” composed by Kapiʻolani CC Vice Chancellor ɲʻ Napoleon, to elders of the King Island community.

Kaaloa offered mele Kū Ka ʻ, “Transformed Waterworn Stones.”

“Through sharing our culture together, I’ve come to realize that the most important thing one must do to keep their culture and their history alive is to have pride in it,” said Kaaloa. “When songs and art are continued through the youth, the culture will continue to live.”

The students will conduct future kōlea counts in Hawaiʻi, support community outreach events and visit classrooms to share their experience. Their participation was made possible through Hawaiʻi Audubon Society scholarships, with airfare funded by the Kapiʻolani CC Lunalilo Scholars Program (which offers scholarships, mentoring and a strong support network).

In celebration of World Oceans Day, the Alaska SeaLife Center featured a captivating exhibit that bridges the worlds of microscopic marine science and fine art. The “Plankton Mandala Art Exhibit” is the culmination of a multi-year collaboration between a team of ocean ecologists from the University of Hawaiʻi at Mānoa and an Alaska-based artist and educator. The intricate artwork captures the beauty of the smallest ocean animals, all created during an artist-in-residence program at Seward Middle School and community workshops at Alaska SeaLife Center. The exhibit opened in April and is still available to the public.

“It is easy to overlook the details of an organism—until you try to draw it,” said Petra Lenz, project lead and research professor at the (PBRC) in the Ƶ Mānoa (SOEST). “Combining art and science allows us to introduce concepts and characteristics that are easily missed. Sensory hairs, eyes, and symmetry take on a new meaning when they become part of a drawing.”

Sharing discoveries with communities

The National Science Foundation-funded science driving this initiative focuses on the annual “spring restart” of the zooplankton community in the Gulf of Alaska, a time when tiny crustaceans awake from a wintertime lull and flourish as days become longer. The PBRC research team is assessing the understudied winter and early spring cycles to determine how species of zooplankton grow, stay healthy and are distributed throughout the water depths. Zooplankton, particularly tiny crustaceans known as copepods, serve as the crucial link connecting microscopic algae to economically vital fisheries, seabirds and marine mammals.

Lenz worked with Alaska artist Kim McNett to develop an innovative educational experience that translates complex biological concepts into hands-on art. While McNett developed the art component, how to engage students and adults in plankton theme artwork, select art materials, sample drawings and reference materials; Lenz and her graduate student Lauren Block worked on the scientific concepts and hands-on science activities.

Latest research

Block also spearheaded much of the fieldwork and foundational research for the project. Highlighting the scientific success of the project, her findings were published in . Block’s research integrated traditional sampling methods with modern molecular approaches to characterize the diversity, development, feeding and physiology of zooplankton in a deep Alaskan Fjord, Resurrection Bay.

Marine mammal research has attained new heights as scientists at the University of Hawaiʻi at ԴDz are deploying noninvasive suction-cup tags onto humpback whales using drones. Traditionally, researchers from the (MMRP) in the approached animals closely via boats, deploying tags using a seven-meter carbon fiber pole. Now, technological advances are allowing the team to tag whales from the sky, dramatically shifting how marine data is collected.

The device’s design ensure the tag lands upright on the whales from a far distance.

During their February 2026 field season off the coast of Maui, the MMRP team successfully utilized drones to deploy Customized Animal Tracking Solution (CATS) accelerometer tags. This innovative method provides a safer, less invasive tag deployment system for both the marine mammals and the human researchers. The team can deploy tags from several hundred meters away from their research vessel—greatly minimizing human intrusion.

“We do not need to get close to the whales to tag them, so we don’t disturb them,” said Lars Bejder, MMRP researcher. “Additionally, we are able to tag whales that we previously were not able to approach and get close to. This opens up many new opportunities for low-impact research on whales and dolphins to inform on their conservation and management.”

A prime example of this success occurred when the team successfully drone-tagged a skittish, singing male humpback whale during its final surfacing bout—a feat that would have been impossible using traditional pole-tagging methods.

Critical data collection

In total, the expedition deployed 22 tags on lactating females, a calf and adult males.

The high-resolution data collected—including fine-scale movements and energy expenditures—is critical for wildlife management. It allows researchers to quantify the biological consequences of disturbances, such as changing climatic events, vessel traffic or military activities, ultimately helping forecast population trajectories and establish vital evidence-based mitigation strategies to protect these marine species.

The fieldwork was supported by the Office of Naval Research, the U.S. Navy’s Living Marine Resources program, Dolphin Quest and philanthropic donations.

Equipped with cutting-edge marine robotics, hyperspectral imagers and aerial drones, five University of Hawaiʻi at Mānoa (MOP) alumni reunited aboard the R/V Searcher in June for a 22-day expedition into Papahānaumokuākea. Their mission was to deploy advanced autonomous systems to combat an invasive macroalgae called Chondria tumulosa.

The expedition highlights the impact of Ƶ’s 50-year-old undergraduate program, proving how MOP produces scientists, engineers and leaders who work fluently across disciplines, agencies and oceans.

“We have a unique opportunity to work with brilliant marine roboticists to develop tools to help combat one of Hawaiʻi’s most mysterious and potentially devastating marine macroalgae species, Chondria tumulosa,” said Chief Scientist Keolohilani H. Lopes Jr., a MOP alumnus and Ƶ Mānoa PhD candidate.

High-tech tools, interagency collaboration

The voyage brought together diverse expertise to monitor and protect fragile ecosystems. Three advanced marine robotic packages—equipped with computer vision cameras, a hyperspectral imager and an environmental DNA (eDNA) profiler—were provided by Matthew Dunbabin’s lab at Queensland University of Technology. Meanwhile, PhD student Anna Baker Mikkelsen of the Climate Resilience Collaborative (CRC) led aerial mapping of Sand Island at Kuaihelani (Midway) using a drone.

Shellie Habel, a coastal geologist with the CRC and , served as primary drone pilot for aerial mapping. At Manawai (Pearl and Hermes Atoll), the team conducted aerial operations over shallow reef flats to supplement in-water surveys of macroalgae. The team also evaluated shoreline changes at Tern Island and East Island of Lalo (French Frigate Shoals) to support research led by Sara Kahanamoku and Haunani Kane at Ƶ āԴDz’s (SOEST).

Decades of trust, leadership

Crucial permit compliance, field safety, and historical context were overseen by MOP alumnus Jason Leonard, Marine Operations Coordinator for the National Oceanic and Atmospheric Administration’s (NOAA) Office of National Marine Sanctuaries Papahānaumokuākea National Marine Sanctuary. Leonard, who has visited the sanctuary for more than 25 years, credited MOP and its Quantitative Underwater Ecological Surveying Techniques field program with preparing exceptional marine field personnel.

Ƶ Mānoa MOP Coordinator Jeff Kuwabara also served as expedition photographer.

“What made this expedition possible wasn’t just funding or equipment,” Kuwabara said. “It was a network of trust built over decades, by people who trained together, dove together, and learned to work across disciplines before they ever had professional titles. That network is MOP‘s quiet legacy: not a single discovery or expedition, but a generation of professionals who know how to collaborate because they were taught to from the start.”

The project highlights 10 years of student-led monitoring of the campus’s nesting population of Manu o Kū (blue-billed tern).

“It’s an amazing privilege to study a native bird on our home campus,” said Bender. “While the technical and data-driven aspects are important, it’s also an opportunity to serve as ambassadors for a native species. When we’re out surveying, we’re visible to the public and have a chance to answer questions, share information, and raise awareness of the Manu o Kū. It’s easy to fall in love with these birds.”

Since 2016, 34 students have participated in the project, producing 25 research posters. Their work documents nesting changes, helps guide campus tree-trimming to protect active sites, and contributes critical data to local conservation databases, broadening students’ professional pathways.

“The return and growth of the Manu o Kū population on our campus is a powerful reflection of what is possible when dedicated faculty inspire curiosity, students embrace discovery, and our entire campus fulfills its kuleana (responsibility) to care for the ʻāina (land),” said Chancellor Misaki Takabayashi. “This recognition celebrates not only our students’ outstanding research, but also a decade of stewardship that has helped to protect Hawaiʻi‘s native species.”

Biology Professor Wendy Kuntz has mentored dozens of students since the project’s inception.

“Watching this project grow over the past decade has been one of the most rewarding parts of my work at Kapiʻolani CC,” Kuntz said. “I am incredibly proud of the four students who presented this research and of the many students who have built on one another’s work, creating a valuable long-term record of Manu-o-Kū nesting on our campus while developing the skills and sense of kuleana needed for conservation work in Hawaiʻi.”

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

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 Hawaiʻi‘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.”

“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.”

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 Hawaiʻi 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, Ƶ Mānoa‘s professor and senior author of the study.

Ƶ Mānoa researchers captured the first footage of green sea turtles helping control aggressive invasive algae.

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

turtle grazing on algae
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.

The invasive red alga Chondria tumulosa forms thick, suffocating mats that smother native coral and threaten Hawaiʻi’s reef ecosystems.

“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 Ƶ 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 Ƶ Mānoa. Smith leads the Limu Lab at Ƶ 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.

This work was accomplished under permit numbers PMNM-2025-001, USFWS 274 Recovery Permit TE72088A-3, Recovery Sub-permit TE163899-2, NOAA Permit 21260, and 275 State of Hawaiʻi, Department of Land and Natural Resources Special Activity Permit 2026-01.

coral reef with fish

The University of Hawaiʻi has been designated as a new Pacific Reef Research Coordination Institute (Pacific RRCI) by the (NOAA) to support coral reef conservation in the Pacific through research, collaboration and public education.

The Pacific RRCI will be housed in Ƶ’s , under the aegis of the , and will perform the following critical functions: conduct federally directed research to fill national and regional gaps; collaborate with relevant states and territories, Indigenous groups, coral reef managers, non-governmental organizations, and other coral reef research centers; assist in the implementation of the NOAA’s National Coral Reef Resilience Strategy and coral reef action plans; build non-federal capacity for management and restoration practices; and conduct public education and awareness programs.

“This new institute combines Ƶ’s strengths in cutting-edge, ocean-related research and our collaborative, place-based approach to working with resource managers throughout Hawaiʻi and the Pacific to protect our vital coral reefs,” said Chad B. Walton, Ƶ interim vice president for research and innovation. “At the same time, it provides us with further opportunities to develop our region’s next generation of researchers and managers in the field of conservation futures.”

To restore and preserve coral reef ecosystems in the U.S. from natural and human-related effects, the Coral Reef Conservation Act of 2000 was reauthorized and modernized by the Restoring Resilient Reefs Act of 2021, which was included in the James M. Inhofe National Defense Authorization Act that became law in 2022. The reauthorized law required the designation of two RRCIs, one each in the Atlantic and Pacific basins, was required. The RRCIs were chosen from 32 preselected coral reef research centers and were designated based on the results of technical merit and panel reviews. The Restoring Resilient Reefs Act of 2021 was introduced and sponsored by Hawaiʻi Senators Brian Schatz and Mazie K. Hirono, and Congressman Ed Case.

The Ƶ-led institute will be guided by experienced reef researchers from Ƶ Mānoa’s Kewalo Marine Laboratory and the Hawaiʻi Institute of Marine Biology, Ƶ ᾱ’s Marine Sciences program, and the University of Guam’s Marine Laboratory. It will support research, monitoring, capacity building and outreach for coral reef management throughout the U.S states and territories of American Samoa, Guam, Hawaiʻi, and the Northern Marianas Islands and with the Freely Associated States of the Federated States of Micronesia, the Republic of Palau and the Republic of the Marshall Islands.

“Many people worked many years to make this vision for collaborative reef research across the Pacific a reality,” said Suzanne Case, director of the Office of Land and Ocean Conservation Futures. “We’re excited to jump in with scientists and communities and agencies across the region to take it forward.”

In recognition of this anniversary, the (PMDP), (SAC) and the (Hawaiʻi Sea Grant) are starting the new, community-centered initiative, Papahānaumokuākea: Bringing the Place to the People.

Papahānaumokuākea is a place of profound cultural, ecological and ancestral significance. Yet for many, it remains distant and abstract. The project seeks to bridge that distance by fostering meaningful, community-led engagement that deepens public awareness, stewardship, trust and cultural connection to the Papahānaumokuākea National Marine Sanctuary. Beginning in summer and fall 2026, PMDP, SAC and Hawaiʻi Sea Grant will host community talk story sessions on Hawaiʻi Island (Hilo and Kona), Maui, Lānaʻi, Molokaʻi, Oʻahu and Kauaʻi.

This initiative centers Native Hawaiian voices, values and leadership, elevating cultural resource conservation and protection as foundational to the sanctuary’s past, present and future. Their vision is a living, island-to-island exchange where communities do not simply learn about Papahānaumokuākea, but actively shape how its story, stewardship and future are carried forward.

Rooted in listening

These gatherings are not presentations delivered to communities, they are conversations rooted in listening. This initiative allows SAC, whose kuleana is to represent the communities, to learn directly from each island community and amplify their voices. The sessions will explore how Western science and Indigenous knowledge systems can be meaningfully integrated, community perspectives on stewardship and management, cultural resource protection priorities, opportunities for youth engagement and leadership, and how communities wish to remain connected to Papahānaumokuākea.

Community organizations, cultural practitioners, educators and schools, conservation groups, youth leaders, kupuna and ʻike holders, and interested individuals are invited to express their interest in hosting, partnering or participating in a talk story session on their island. The initiative is an invitation to listen, learn and steward together.

The aquarium will host a 122nd birthday celebration on March 19, from 9 a.m. to 2 p.m. The day kicks off with a community coastal cleanup followed by a suite of family-friendly activities.

A new chapter

Lemus brings a wealth of experience in marine facility management, research, and education. Lemus served for four years as the interim director of the (HIMB) within the University of Hawaiʻi at Mānoa (SOEST) and is currently the interim associate dean for academic affairs in SOEST. Her primary focus at the aquarium is on operational improvements and enhancing the institutionʻs role in education, marine conservation, collaborative research, and community engagement.

“Managing the Waikīkī Aquarium is about more than just animal husbandry; it’s also about our engagement with the public and contribution to conservation of Pacific species, and our role as a public outlet for Ƶ research,” said Lemus. “As we celebrate 122 years, we are not just honoring our history, but building the systems, facilities, and stories that will carry us through the next century.”

One major accomplishment under her leadership has been the successful return of Hōʻailona, the beloved Hawaiian monk seal, to his refurbished enclosure.

New and upcoming exhibits:

  • The Aquaculture Tank: In partnership with Biota, a local aquaculture company, this exhibit will feature fish and coral raised entirely in aquaculture facilities at the Oceanic Institute and Waikīkī Aquarium. This “no-collection” model highlights sustainable trade and will also showcase 3-D structures from HIMB researcher Josh Madin’s Lab that facilitate coral growth.
  • The Edge of Reef Redesign: Formerly an iconic outdoor exhibit, the Edge of Reef was dismantled to make way for a critical infrastructure project. A redesign is planned for this exhibit with support from Ƶ, the Ƶ Foundation, and the Friends of the Waikīkī Aquarium.
  • New Tank for Mullet and More: The large tank that previously featured mullet, a species revered in Hawaiʻi as a staple food and in loko ʻia (Hawaiian fishpond) aquaculture, is being dismantled to make way for a modern habitat. The new enclosure may house mullet and possibly other compatible species such as rays or sea turtles.
  • The aquarium is planning new collaborations with a variety of Ƶ faculty and labs to help bring their work to broader audiences.
  • AZA Accreditation: The aquarium is starting a Pathway Toward Membership program with the Association of Zoos and Aquariums, the gold standard in accreditation for zoos and aquariums, with the goal of achieving AZA accreditation for Waikīkī Aquarium in about 5 years.

Fire and firefighters

A $2-million gift from Jeff Bezos and Lauren Sánchez Bezos is supporting University of Hawaiʻi-led research aimed at restoring fire-prone grasslands on Maui and reducing the risk of future wildfires, building on and long-term recovery following the devastating 2023 fires.

Grass
Guinea grass

Much of Maui’s former sugar plantation lands are now unmanaged and dominated by invasive species, such as guinea grass, that create more fire-prone vegetation and intensify wildfire risk. Several Ƶ units are collaborating to address that vulnerability through land stewardship research designed to inform policy and guide on-the-ground management decisions.

The effort brings together researchers from the (ƵERO) housed in Ƶ ԴDz’s , the , and the Ecosystems and Land Care Program in the Department of (NREM) in the College of Tropical Agriculture and Human Resilience. The work will be conducted with watershed partners, ranchers and ʻāina (land)-based organizations across Hawaiʻi.

“Insufficient investment in land care across former plantation lands has left large areas of Maui vulnerable to wildfire,” said Kimberly Burnett, a specialist with ƵERO. “This work builds on evidence that actively managed lands, including forests, well-managed rangelands and agriculture, can significantly reduce fuel loads and support outcomes like erosion reduction, food production, biodiversity and community resilience.”

Data-driven strategies for wildfire prevention

In the early stages of the project, researchers will work closely with partners to co-develop research questions and products that are directly useful for land managers and decision-makers. Anticipated outcomes include statewide wildfire risk and probability maps to help guide fire reduction strategies across a range of land uses, as well as analyses of different wildfire mitigation scenarios over space and time.

Those scenarios may include forest restoration, green breaks, agroforestry, grazing and mowing, with researchers assessing the benefits and costs of each approach.

“We want to look at options beyond just mowing brush given how well these different actions align with other things people value and contribute to public safety,” said Clay Trauernicht, a specialist with NREM.

The project will also examine policy and market-based tools that could help finance and support land-use transitions that advance multiple ecosystem services, including wildfire risk reduction, across Hawaiʻi.

The gift builds on existing support from the Bezos Maui Fund to restore the island’s watersheds and reduce wildfire risk, and reflects a broader strategy that links environmental recovery with community resilience. That land-based work is complemented by a separate $1.5-million investment to support Lahainaluna High School graduates enrolled at Ƶ who continue to face economic hardship following the fires.

“We are profoundly grateful to our donors for their continued commitment to Maui,” said Ƶ Foundation CEO and Vice President of Advancement Tim Dolan. “Their support is making a lasting difference for the people and places that define this community.”

Mature ramie caterpillars are most often black in color with distinctive red spots, yellow markings on its sides, and long white hairs.

A live ramie moth (Arcte coerula) caterpillar was discovered on Kauaʻi last month, marking the first detection of this invasive species on the Garden Isle.

The discovery from a community report to the Kauaʻi Invasive Species Committee has sparked a swift response from the University of Hawaiʻi at Mānoa, the Department of Land and Natural Resources, and the Hawaiʻi Department of Agriculture and Biosecurity.

Adult ramie moths are nocturnal and feed on tree sap or rotting/overripe fruit.

Growing threat to native ecosystems

Ramie moth caterpillars are prolific feeders known to quickly defoliate māmaki (Pipturus albidus), a native Hawaiian plant vital to our forests and culturally significant for its use in lāʻau lapaʻau, traditional Hawaiian healing practices.

“We are really worried about this because we’ve seen it spread from Maui to the Big Island in 2020, then to Oʻahu in 2024, and now to Kauaʻi,” said Michelle Au, a graduate student at the Ƶ Mānoa (CTAHR) who has been tracking the pest since 2019.

Au highlighted the broader ecological risk: the caterpillars also feed on other endemic nettles including endangered species like maʻoloa (Neraudia angulata). The ramie moths also compete for the same resources with native species such as the Kamehameha butterfly and endangered endemic land snails.

Finding natural predators

moth eggs
Ramie moth eggs are mostly found individually on the underside of leaves, along the leaf edge or veins. It takes less than a week for eggs to hatch once laid.

As the moth continues its rapid expansion across the islands, Au’s research has focused on the detection of resident natural enemies that could help manage this pest. “We’ve been looking for predators and parasitoids already in our environment that may expand its host range and attack the eggs, caterpillars, and adults of the ramie moth, helping to manage populations from devastating levels,” Au said.

Au’s research monitors specimens at various field sites to determine what percentage of ramie moth eggs reach adulthood, which then will lay eggs and inflict future damage.

Community help needed

“I rely heavily on public reports of this pest, especially for new detections,” Au said. “The biggest thing for us right now, especially for Kauaʻi, is to raise awareness in order to track the spread of this pest.”

Officials ask the public to report sightings with photos to or email ipmlab@hawaii.edu. Ƶ CTAHR’s extension page on the for more information.

For the first time, scientists have calculated a detailed “energetic budget” for Hawaiʻi‘s short-finned pilot whales, revealing what it takes to power their extreme, 800-meter (2,600-feet) dives for food.

A new study led by the University of Hawaiʻi at āԴDz’s (HIMB) found an average adult whale must eat 142 squid daily to survive, scaling up to 416 million squid annually for the entire population of short-finned pilot whales. This data, published in the , provides a new benchmark for protecting the historically understudied marine mammals.

“Pilot whales are one of the only oceanic dolphins that regularly dive to extreme depths—up to 1,000 meters—to find prey,” said William Gough, (MMRP) postdoctoral researcher and lead author of the study. “This deep-diving, high-risk foraging strategy requires a delicate balance between the energy they spend and the energy they acquire. Our study is the first step in quantifying that balance for this specific population.”

Understanding precisely how much energy the animals require is essential for understanding how to effectively manage against threats and ensure their survival.

“This detailed scientific data gives Hawaiʻi management agencies a critical tool to monitor how changes in the ocean—from warming waters to ship noise—might push the pilot whales past their survival limit,” said Lars Bejder, MMRP director and co-author of the study.

The deep waters surrounding the Hawaiian Islands are home to a genetically distinct population of short-finned pilot whales. These highly social, toothed whales are not migratory; they remain with their tight-knit, multi-generational families in one region for life. The population forages year-round where they pursue their preferred prey: squid.

Requirements can inform effective management

“Deep-diving species like pilot whales are especially vulnerable to human-induced disturbances, such as noises from ships or changes in ocean temperature, which can disrupt foraging or increase their energetic costs,” said Gough. “If they use more energy than they can find, they face an energy crisis that weakens their health, hurts their ability to fight off disease, and ultimately limits their ability to reproduce and recover the population.”

Despite this inherent vulnerability, the Hawaiian pilot whale population benefits from a stable and abundant squid food source, which may better equip them to cope with environmental disturbances than populations elsewhere.

The team placed advanced Customized Animal Tracking Solutions (CATS) tags on eight short-finned pilot whales off the coast of Lānaʻi between 2021 and 2024. The tags recorded movement, depth and sound, and used 2K cameras with LED headlights to observe the whales in their lightless, 800-meter-deep hunting habitat. The researchers developed a new method to estimate minute changes in energy usage by combining data from tags with body measurements from aerial drone footage.

“Getting to be on the water and close to these animals is an absolute joy,” said Gough. “But the fact that we can see into their world, even at 800 meters and under extreme pressures [80 times that at the surface], and observe them capturing their food in complete darkness, feels unbelievable to me. It’s truly a privilege to document the lives of these elusive, deep-diving whales.”

A new study by researchers from the University of Hawaiʻi at Mānoa’s (HIMB) has revealed that endangered Hawaiian monk seals have a hidden vocal repertoire, using a complex range of sounds to call underwater.

Previously, scientists believed monk seals had a simple repertoire, identifying only six different calls based on seals in human care. In this study, the scientists analyzed thousands of hours of passive acoustic data from the wild, they discovered 25 distinct vocalizations.

The study, published in , also found that these low–frequency calls are produced by the seals throughout the day. These vocal types were heard consistently across the Hawaiian archipelago, with calling rates highest at sites where more seals were present. This new understanding of the monk seals (Neomonachus schauinslandi) vocal repertoire opens up a new window into their acoustic behavior.

“We discovered that Hawaiian monk seals—one of the world’s most endangered marine mammals—are far more vocal underwater than previously known,” said Kirby Parnell, lead author of the study and a PhD candidate with (MMRP). “By analyzing over 4,500 hours of recordings from across the Hawaiian Archipelago, we identified more than 23,000 vocalizations representing at least 25 distinct call types.”

Monk seal vocalizations

The study, which deployed passive acoustic recorders at five key monk seal habitats from Molokaʻi to the Northwestern Hawaiian Islands, uncovered:

Expanded vocal repertoire: Researchers identified 20 previously undocumented calls.

Novel communication strategy: The research provides evidence that monk seals can combine different vocalizations together, creating “combinational calls”—a communication strategy never before reported in any pinniped (seals, sea lions and walruses) species.

A foraging call: The team discovered one novel elemental call type “the whine” produced during foraging, representing only the second known example of a seal species using vocalizations while pursuing prey.

“We were surprised by the sheer diversity and complexity of monk seal vocalizations,” said Parnell. “The discovery of combinational calls, where seals link multiple call types together, suggests a previously unknown level of complexity in pinniped acoustic communication. Finding a new call type—the Whine—associated with foraging behavior was also unexpected and suggests that monk seals may use sound not only for mating or socializing, but possibly for foraging purposes as well.”

Seal conservation in Hawaiʻi

These results lay the foundation for using passive acoustics to monitor monk seal populations to protect their acoustic habitats as human activity persists in Hawaiian waters. Future research will decisively link these documented vocalizations to specific Hawaiian monk seal behaviors, such as foraging, swimming, social interactions and reproduction. Next steps involve developing automated detection systems to monitor the seals’ acoustic activity more efficiently and non–invasively.

“This research provides the first comprehensive description of free–ranging Hawaiian monk seal underwater sound production, an important step toward understanding how they use sound for critical life–history events,” said Lars Bejder, director of MMRP, professor at HIMB and co–author of the study. “Because their vocalizations overlap with the same low–frequency range as many human–generated sounds (e.g. vessel noise), this work lays the foundations to evaluate how ocean noise may affect communication, reproduction, and behavior in this endangered species.”

About the team

The team included undergraduate and graduate students, and recent Ƶ alumni, and coauthors from France and the .

“Manually annotating over 23,000 calls by hand is no small feat, and I have a team of interns to thank for helping with the analysis!” said Parnell. “This research would also not have been possible without the support of the Hawaiian Monk Seal Research Program, who deployed and retrieved the acoustic recorders in the .”

The work was supported by NOAA Fisheries via the Cooperative Ecosystem Studies Unit (CESU) award NA19NMF4720181.

Hansen presented at Ƶ Research at the Capitol Day.

University of Hawaiʻi at Mānoa alumna Lauryn Hansen can pinpoint the moment she realized she could turn her passion for the environment into a career, beginning a journey that would eventually lead her to dive deep into the intricate links between ocean and human health.

“My high school history teacher showed our class a clip of a late-night talk show where lobbyists in powerful positions chatted about their stance on climate regulation,” said Hansen. “It was the first time I really thought about how the world worked—and how often people making the biggest decisions may not act in the public’s best interest. That was an ‘aha’ moment for me: realizing that I could channel my deep care and interest in the environment into a career.”

person picking up trash

That realization led Hansen, who grew up in California and the Pacific Northwest, to Ƶ Mānoa. She enrolled in the (GES) bachelor’s degree program in the (SOEST).

For her GES senior thesis, Hansen worked with Robert Richmond at the Kewalo Marine Laboratory to investigate how exposure to PFAS, a type of “forever chemical,” influenced different phases of the coral life cycle. This project sparked a strong interest in toxicology and contamination, which ultimately steered her toward pursuing a bachelor’s and master’s (BAM) combined degree in public health at Ƶ Mānoa.

“The transition to public health ended up being a really natural fit,” Hansen said.

Linking research and community

Now, as an with the Ƶ Sea Grant College Program (Hawaiʻi Sea Grant), Hansen is focusing on coastal marine resource management related to contaminants of emerging concern, such as forever chemicals, pesticides and microplastics. She collaborates with researchers, water quality managers and government agencies to improve local monitoring and management of these contaminants.

In addition to her research, Hansen contributes to Ƶ ԴDz’s efforts to become a Native Hawaiian Place of Learning. After completing Cohort Kaulua, a professional development program, she became a trained Pilina Circle co-facilitator to support spaces for reflection and connection among the campus community.

Looking ahead, Hansen plans to continue working in environmental health with a focus on outreach.

“What matters most to me is being in a role where I can take research beyond the ‘ivory tower’—working with people, shaping conversations, and helping create solutions that make a real difference,” Hansen said.

To encourage a deeper connection with the ocean and foster ocean stewardship across generations in Hawaiʻi, the (Hawaiʻi Sea Grant) and Ƶ Mānoa , in collaboration with the Hawaiʻi Symphony Orchestra (HSO), presented Symphony of the Hawaiʻi Seas at the Neal S. Blaisdell Concert Hall on October 23. The free concert captivated audiences by weaving together moʻolelo (storytelling), mele (music), hula and animations.

The performance featured HSO performing ocean-themed original compositions by celebrated local composers Michael-Thomas Foumai, Herb Mahelona, Takuma Itoh, Logyn Okuda and Justin Park. The music was paired with vibrant animations by Kari Noe, Janae Taclas, Dillon Valenzuela, Jewel Racasa, Sam St. John, Edward Ayano, Napua Rice, Huy Nguyen and Kieren McKee.

“We have the research at Ƶ, and we have the finest musicians, world class orchestra, and when we combine those together, we have a powerful message to send to the world using music that goes straight to the heart,” said Foumai, the director of artistic engagement for HSO and also a lecturer at Ƶ–West Oʻahu.

The program also included a mele composed by Ƶ Professor Rosie Alegado and Ƶ Indigenous Stewardship Specialist Aimee Sato accompanying a hula under the guidance of Kumu Hula, Kekuhi Kealiʻikanakaʻoleohaililani and Hawaiʻi Community College Professor of Hawaiian Studies Taupōuri Tangarō. Cultural narratives guided audiences through time alongside native sea life and ʻaumākua (family or personal gods), exploring the vital role humans play in protecting cherished waters.

School performances

Symphony of the Hawaiʻi Seas featured two morning performances for students in grades 4–12. These free school concerts were designed to support STEAM learning, cultural literacy and environmental awareness in classrooms.

“And so it’s exciting to bring all of this talent together to provide an opportunity for our 4th and 12th grade students to be in a symphony, to be in a concert hall, and to get to see all of it in such an immersive experience,” said Beth Lenz, PhD, Hawaiʻi Sea Grant assistant director for strategic communications and engagement.

“It was my first time going to one of those kinds of events,” said Brad Park, Papahana O Kaiona Alternative Learning Program sophomore. “It was very peaceful, I had a peaceful feeling listening to the orchestra. And I liked how it kind of matched the vibe of the video, that’s what I liked.”

Continuing the education through music

This performance continued the successes of the Symphony of the Hawaiian Birds and Symphony of Hawaiʻi Forests. The Symphony of the Hawaiʻi Seas represented a new chapter in creative collaboration, bringing together Ƶ, local experts and organizations, as well as federal, state, and county agencies to weave culture, science, and the arts into an inspiring shared experience.

“They’re not pre-written works written by someone from outside of Hawaiʻi,” said Takuma Itoh, DMA, composer and professor of music at Ƶ Mānoa Department of Music. “They’re all created here locally, just like the animation, just like the hula, just like everything in this project.”

The program was a collaborative effort supported by Hawaiʻi Sea Grant and the Ƶ Mānoa Strategic Investment Initiative, led by Lenz of Hawaiʻi Sea Grant, with co-investigators Itoh, Kalilinoe Detwiler (Ƶ Mānoa English Department), Anne Rosa (Hawaiʻi Sea Grant), Melissa Price (Natural Resources and Environmental Management Department) and Kanesa Duncan Seraphin (Hawaiʻi Sea Grant).
