UOG-hosted town hall explores ocean energy for aquaculture, island power-source

Bastian Bentlage, associate professor of Bioinformatics at the UOG Marine Lab and one of the leads from UOG, speaks at the November town hall meeting, 'Ocean Energy Systems to Power Guam Aquaculture.' Bentlage states that UOG'd primary role in the project is to provide insights into site-specific considerations for evaluating the feasibility of deploying ocean energy systems.

While ocean energy system technologies are still in the development stage, their potential as a renewable energy source is promising, according to a technical report from a study developed by a team from the University of Guam, Pacific Northwest National Laboratory (PNNL), and Sandia National Laboratory.

The findings presented at a November town hall meeting, “Ocean Energy Systems to Power Guam Aquaculture,” focused on utilizing ocean thermal energy conversion (OTEC) and wave energy conversion (WEC) technologies to power a proposed Guam Aquaculture Innovation Center and, potentially, as a renewable power source for Guam.

UOG hosted the town hall with the support of Guam NSF EPSCoR and the Center for Island Sustainability and Sea Grant, during which PNNL, the lead entity for the project, presented the findings and gathered feedback from community participants to inform future research.

Since the performance of OTEC and WEC systems is site-specific, they examined two potential locations for the proposed aquaculture center: Tanguisson on the west side of Guam and an area near the UOG Marine Lab on the east side, according to Bastian Bentlage, associate professor of Bioinformatics at the UOG Marine Lab.

“One of the questions we asked is what are the options for powering an aquaculture facility using renewable energy that harvest the power of waves or thermal gradients between surface and deep-sea waters,” Bentlage said.

Bentlage explained that UOG’s primary role in the project was to provide insights into site-specific considerations for evaluating the feasibility of deploying these ocean energy systems. He emphasized the importance of including team members familiar with Guam’s unique landscape and marine environments.

Bentlage and David Crisostomo, an aquaculture specialist with the UOG Sea Grant Program, are leading the research at UOG for this project.

Crisostomo described the proposed aquaculture center as a potential game-changer for Guam’s aquaculture industry. He stated that the center will serve as a research hub for cultivating local species. Additionally, it could provide a business incubator setup for individuals interested in entering the aquaculture industry.

At the town hall, the project leads presented the benefits as well as the infrastructure, environmental, and economic impacts of OTEC and WEC.

In her presentation, Fleur de Peralta, senior advisor with the Risk & Environmental Assessment Group at PNNL, highlighted the benefits and challenges of ocean energy systems for Guam. She stated that OTEC can provide baseload power, which helps stabilize the grid and supports black start capabilities. The ocean’s depth near Guam is ideal for the technology, and the consistently warm surface temperatures ensure an adequate temperature differential. Additionally, OTEC, once deployed, will create jobs in installation and maintenance, among others.

However, there are challenges to consider. For OTEC, further research is needed to assess water temperatures and depths accurately, and environmental protection requires additional study. The permitting process remains unclear among various agencies, and shore-based plants must be designed to withstand natural hazards.

Regarding WEC, de Peralta presented assessments by Sandia that indicate Guam possesses substantial wave resources. However, ensuring a reliable survival strategy for installations is essential, and deployment can be costly, necessitating a careful balance of cabling and mooring expenses with location choices.

De Peralta noted, “Outreach engagements with the Guam community and stakeholders is an important part of our project to gain insights on the use of marine energy systems as a clean energy power source and considerations on the potential impact on the island, environment, culture, and livelihood of the island’s communities.”

Peralta, who grew up in Guam, said that the information shared during the town hall discussions will inform further assessments and the development of ocean energy systems.”

Meanwhile, Charles Gunzel, a program manager at PNNL, also emphasized the importance of community feedback, which ocean energy system designers should consider.

“It’s extremely satisfying to engage with the residents of Guam, learning their unique concerns, so these can be made known to the planners, designers, and manufacturers of tomorrow’s ocean energy systems,” Gunzel said.

According to Bentlage, a significant outcome of this project is the strengthened partnership between UOG and the two National Laboratories that lead in renewable energy research and development.

“We intend to build on this relationship to enhance research capacity in this area, supporting informed decision-making as Guam works to diversify its economy and transition to renewable energy,” Bentlage stated.

The project commenced in early 2023 after receiving funding from the US Department of Energy Water Power Technologies Office (WPTO).

Charles Gunzel, a program manager at Pacific Northwest National Laboratory, highlights the importance of community feedback in designing and developing ocean energy systems. Gunzel participated in the "Ocean Energy Systems to Power Guam Aquaculture" town hall meeting in November.

At the “Ocean Energy Systems to Power Guam Aquaculture” town hall meeting in November, presenters shared findings on ocean energy systems from a technical report by the University of Guam, Pacific Northwest National Laboratory, and Sandia National Laboratory. The focus was on OTEC and WEC technologies to power the proposed Guam Aquaculture Innovation Center and support renewable energy efforts for Guam. They also gathered feedback from members of the community.

Dr. Terry Donaldson: From cold Lake Michigan to sunny Guam

Everyone knows that Terry Donaldson, PhD, is the principal investigator and project director of Guam NSF EPSCoR, but not everyone is aware of his journey as an ichthyologist. When did this interest in marine biology begin?

For Donaldson, it began as a child growing up by the cold lakes of Michigan and following the adventures of Jacques Cousteau through books and television series. It was no surprise that he developed an admiration for fish, having spent a great deal of his childhood snorkeling to find them or catching them with his grandfather.

Donaldson earned his doctorate in Ichthyology which led to him studying various species around the world including New Zealand, Japan, French Polynesia, the Solomon Islands and Guam, where he has been serving the University of Guam’s Marine Lab for over many years.

“Fish can be really beautiful to look at,” said Donaldson, noting that he can enjoy just watching and observing the sea creatures, from physical characteristics to their behaviors. Astounded by the sheer diversity – thousands of species, that we know of – he finds fulfillment in the discovery of new species as well as new observations on existing ones.

One of his most recent publications details the communication behaviors of squirrelfish, which reflects his interest in bio acoustics that stems from undergraduate studies at Michigan State University.

The paper, titled “Production of sounds by squirrelfish during symbiotic relationships with cleaner wrasses,” observes nine species of Holocentridae (squirrelfish) and how they use acoustic signals to communicate in their interactions with cleaner wrasses.

Throughout this life-long journey in Ichthyology and marine biology, Donaldson has also ended up in several leadership positions including principal investigator and project director of Guam NSF ESPCOR and the former head of UOG’s Marine Laboratory.

Most recently, he was elected as President of the National Association of Marine Laboratories in January of this year.

With decades of experience in research and leadership, he subscribes to the belief that learning is a lifelong endeavor.

“Every day I come through the door and I learn something new. Often people in this building teach me or just (through) interacting with other people, I learn something new,” he said nothing that Guam NSF EPSCoR’s successes are not just from his leadership but because he has a talented team working with him.

“Don’t be afraid to get your feet wet!” Donaldson said, offering a piece of advice to those just starting their careers.

He believes in the importance of trying new activities and cultivating interests that can be useful years down the line. This belief has certainly proven true for this scientist, whose love for marine animals started well before his own career took off.

Bioblitz survey finds false spider crab in Guam

Among over a thousand species that were found during the University of Guam’s first Bioblitz is the Elamena castanea, a type of false spider crab.

While the Elamena castanea superficially looks like one, this species is not actually a spider crab and belongs to the Hymenosomatoidea superfamily which means they aren’t even related to true spider crabs.

Originally discovered in the Philippines, this is the first time that the species has been observed here in Guam even though the area has been sampled numerous times through the decades.

Since this discovery, several more crab specimens have been found on the reef flat behind the UOG Marine Lab.

“It shows you how much diversity there is out there,” said Robert Lasley, PhD, UOG Biorepository crustacea curator. “Elamena castanea specimens were collected under rocks or in seaweed in shallow depths – usually less than 1-2 meters.”

Lasley notes that even after the three-week biological survey, there are still hundreds, possibly even thousands, of marine species that remain undocumented in the waters off Guam.

“Honestly, though, we find new records all the time, often without noticing it,” he said. “It takes a lot of work at the microscope and digging through literature to confirm if something is a new species or new record.”

Along with the Elamena castanea, other findings included new records of different species of isopods, nudibranchs, nemerteans, gobies, and shrimps.

It has been estimated that between 10 to 15 percent of the specimens collected during the BioBlitz are either new records or entirely new species.

Since February, the Biorepository team has been developing and cataloging the specimens and uploading the specimen data to the Biorepository database.

Soon, they will be able to loan out specimens to researchers so that they can be further examined and new information can be reported.

The team is also planning future biological surveys with more targeted searches for specific organisms, using the information collected during this first Bioblitz.

In addition, they intend to organize surveys in other places throughout the region, such as Palau and the Marshall Islands.

Through these surveys, researchers will be able to learn more about what organisms call the vast ocean home, including the Elamena castanea, which will also help the community learn how to preserve and protect them.

Collaborative study yields new research instrument

After a detour to Alabama following the 28th NSF EPSCoR National Conference in Nebraska, Bastian Bentlage, PhD, Associate Professor of Bioinformatics, brought home a newly developed scientific instrument to aid in coral research.

Bentlage, with accompanying graduate research assistant Nikko Galanto, made the journey out to the Dauphin Island Sea Lab, located on Alabama’s Gulf Coast. The lab has been developing the build and circuitry of a new scientific research instrument, as well as the computer models and programs needed to run it. This instrument measures the performance of a coral’s photosystem under heat stress using fluorescent light.

“If you shoot a blue light at a chloroplast, like let’s say an algal cell, not all of the energy from the light is actually seamlessly converted right into making sugars and by extension energy,” Bentlage explained. “So, you can actually measure the amount of fluorescence that is produced and by extension then can make some inferences about the underlying health of the chloroplast.”

With this new method, the researchers hope the instrument will help to identify corals that are most resilient to increasing sea surface temperatures so they may be prioritized for reef restoration.

This particular research project is conducted in collaboration with Kenneth Hoadley, Ph.D., from the University of Alabama and Mark Warner, Ph.D., from the University of Delaware, with Bentlage and Marine Lab director Laurie Raymundo, Ph.D., representing the University of Guam.

The connection stemmed from another proponent of the research project Victor Bonito, Ph.D., director of Fiji-based non-profit Reef Explore Fiji, Ltd. The universities first approached Bonito to write a grant to help expand their existing research. As a graduate of the UOG Marine Lab, it was through Bonito’s recommendation that the UOG Marine Lab be sought out for collaboration.

“It was really interesting for me to visit, to see a different approach to science,” Bentlage mentioned. “I’ve never really thought about, or didn’t know really where you would start to work with someone who was actually in that space where, ‘hey, we’re actually developing the technology to measure certain things.’”

The two universities plan to visit Guam next year to see what results the instrument has found, as well as to conduct their own research and experiments.

Lasley ready to bring crab education to students on Guam in latest CHalan Deskubre

Crabs have always had a special place in Robert Lasley’s heart, and now he is sharing that love to help educate students on Guam.

As a part of the placed-based educational magazine CHalan Deskubre, which is supported by Guam NSF EPSCoR, Lasley has lent his “crab genius” so the children of the island may learn more about the crustaceans and what they do for our ecosystem.

According to CHalan Deskubre Editorial Coordinator Maria Louella Losinio, who also works on the EPSCoR Science Communication Team, Lasley’s gift for conveying science in an easily digestable way makes him a great fit for the magazine.

“The target audience for this magazine is school aged people from kinder through twelve grade and something we can all agree on is the intrigue they all share about animals around Guam,” said Losinio. “Dr. Lasley is able to bring information about the crabs to them in ways that they not only learn from, but are entertained by too.”

Lasley will be featured in the second issue of the magazine, which focuses on Sustainable Development Goal #14 – Life Below Water.

The issue is set to launch this month and will be available to students all around Guam.

Coral research could have big implications for Guam’s future

Research by Reilly Kleven at the University of Guam (UOG) has revealed the remarkable growth potential of branching Lithophyllum coralline algae, a vital component of Guam’s coral reefs.

Kleven is a Graduate Research Assistant with the Guam National Science Foundation’s (NSF) Established Program to Stimulate Competitive Research (EPSCoR) at UOG.

Kleven’s research, conducted under the guidance of Tom Schils, Ph.D. of the UOG Marine Labratory, focused on quantifying the growth rates of these algae in various reef habitats around the island. By utilizing advanced 3D scanning techniques, Kleven was able to measure the growth of individual algae samples over an extended period.

“Nongeniculate coralline algae are one of the most abundant calcifiers on Guam’s reef. They provide a variety of ecosystem services for reef environments. They help build and stabilize reef framework by depositing calcium carbonate in the form of magnesium calcite skeletons,” explained Kleven. “They act as important binders, decreasing the likelihood of structural collapse by reinforcing caves and cavities. Their skeletons further contribute to the resilience and recovery potential of reefs, providing protection from disturbances such as bio erosion and tsunamis.”

One of the most significant findings of the study was the exceptional growth rates observed in Lithophyllum algae from Pago Bay, Guam. These algae demonstrated remarkable resilience, growing at a rate that far exceeded previous estimates for coralline algae in tropical regions.

Kleven’s research also highlighted the importance of environmental conditions on algal growth. While Pago Bay offered optimal conditions for Lithophyllum growth, factors such as nutrient levels, sediment output, and water temperature were found to significantly influence growth rates in other areas, such as Togcha Bay.

These findings have significant implications for understanding the resilience of Guam’s coral reefs and their ability to recover from disturbances. As climate change continues to threaten coral ecosystems, the growth potential of lLithophyllum algae offers hope for future reef conservation efforts.

“As coral bleaching events become more frequent and severe the significance of coralline algae increases. These algae are likely to play a crucial role in preserving tropical reef carbonate structures as environmental change continues,” added Kleven.

Kleven’s research marks a significant contribution to the field of marine biology and provides valuable insights into the complex dynamics of coral reef ecosystems at a time when many see the importance of the protection of our reefs.

Guam NSF EPSCoR supports sustainable fisheries through fish maturity workshop

From May 28 to June 14, 2024, graduate students from the University of Guam as well as scientists from Saipan attended a workshop called Jungle Histology: Fish Gonad Analysis at the UOG Marine Laboratory to learn how to determine the sex and maturity of reef fishes.

“At the most basic level, one of the things that people seem to understand is that it’s a good idea not to catch a fish and eat it until it’s had the chance to reproduce,” said Ken Longenecker, Ph.D., an associate researcher at Bishop Museum and one of the workshop’s facilitators. “But we don’t know the size at which fish reach maturity for about 83 percent of exploited species worldwide.”

Histology is a discipline of biology that examines the microscopic anatomy of biological tissues. In the case of fish histology, the gonads of a specimen are extracted, processed, and then examined with a microscope.

“There are resources here I don’t have back home, so I look forward to learn what I can at these workshops and bring this knowledge back and teach the people there,” said Naomi Billimon, a student at the Northern Marianas college in Saipan and an intern at the CNMI Division of Fish and Wildlife.

From May 28 to June 14, 2024, graduate students from the University of Guam as well as scientists from Saipan attended a workshop called Jungle Histology: Fish Gonad Analysis at the UOG Marine Laboratory to learn how to determine the sex and maturity of reef fishes.

This workshop was the final segment of the two-part, weeklong Fish Life History Workshop series funded by Guam NSF EPSCoR to enhance regional research capacity within Micronesia and improve the management of fisheries within the Pacific.

Three visiting scientists from Hawai’i facilitated the session: Ken Longenecker, Ph.D., an associate researcher at Bishop Museum; Ross Langston, Ph.D., a professor of biology at Windward Community College; and Erik Franklin, Ph.D., an associate research professor at the Hawai’i Institute of Marine Biology at the University of Hawai’i at Manoa.

According to Longenecker, knowing whether a fish is mature is essential to the sustainability of fisheries.

“At the most basic level, one of the things that people seem to understand is that it’s a good idea not to catch a fish and eat it until it’s had the chance to reproduce,” said Longenecker. “But we don’t know the size at which fish reach maturity for about 83 percent of exploited species worldwide.”

Histology is a discipline of biology that examines the microscopic anatomy of biological tissues. In the case of fish histology, the gonads of a specimen are extracted, processed, and then examined with a microscope.

Typically, histological practices require working in a laboratory with specialized equipment, but according to Langston, the method of jungle histology is unique because its needs are minimal.

“We can do this work with just a few batteries, so we don’t need much in the way of infrastructure,” said Langston.

Bolstering regional research capacity
Workshops like this one are crucial in supporting communities within the Pacific who rely on their fisheries for sustenance.

“For a lot of places like Saipan and Guam and other areas in the Pacific, fish are the primary or even the only source of protein that some people have in their diets, so it’s extremely important that we are able to give them data so that they can confidently manage their harvest year after year without depleting their stocks,” said Franklin.

Improving regional research capacity allows scientists to answer questions so that they can serve the interests of their communities and even teach other researchers skills that they have learned.

“There are resources here I don’t have back home, so I look forward to learn what I can at these workshops and bring this knowledge back and teach the people there,” said Naomi Billimon, a student at the Northern Marianas college in Saipan and an intern with the CNMI Division of Fish and Wildlife.

Guam NSF EPSCoR bolsters regional research capacity through fish ageing workshop

On Monday, May 21, 2024, University of Guam graduate students, members of the Guam Green Growth Conservation Corps, as well as visiting scientists from Saipan, Palau, and Hawai’i convened at the UOG Marine Laboratory to learn how to determine the age of fish.

To determine a fish’s age, scientists extract a bonelike structure called an otolith within its ear and count its growth rings.

“Otoliths grow throughout time just like a tree. If you cut one in half, you can count the rings that are being laid down every single year,” said Brett Taylor, Ph.D., the workshop facilitator and an assistant professor of fisheries ecology at UOG.

Many of the participants, such as Christina Muller-Karanassos, a researcher from the Palau International Coral Reef Center, had varying levels of experience regarding extracting, processing, and reading otoliths. “I hope I can use this information in the future because we want to collect life history information for more fish species,” said Muller-Karanassos. “Nobody where I work really does any fisheries work, so I hope I’ll be able to pass on the knowledge to some people there.”

According to Taylor, around 300 fish species are harvested in Guam. Knowing how to ascertain the age of a fish is vital to habitat conservation, fisheries management, and maintaining the perpetuation of local fishing practices and culture.

Many of the participants, such as Christina Muller-Karanassos, a researcher from the Palau International Coral Reef Center, had varying levels of experience regarding extracting, processing, and reading otoliths.

As part of the workshop, participants gained experience extracting otoliths from a variety of reef fish species at different life stages to hone their skills.

“The next part, which will be taught by our colleagues from Hawaii, will cover the histology of fish gonads. These workshops are putting together the two data pillars of life history information which are how old the fish are and what their maturity status is. When you put those two elements together, you can piece together the biology of the species,” said Taylor.

Visiting scientists enrich Guam’s local community through research symposium

As part of the University of Guam’s first Bioblitz, an event focused on finding and identifying as many species as possible in a place over a set period, a team of international scientists engaged the island’s local community through a mini research symposium held on Friday, February 16, 2024.

These scientists, who hail from the United States, Italy, and Japan, held a series of presentations concerning organisms such as mollusks, worms, shrimps, and other invertebrates to increase local research capacity and generate interest in these under-studied fields.

One of the presenters was Florida Museum Curator of Invertebrates Gustav Paulay, Ph.D., who formerly served as the director of the UOG Marine Laboratory. “UOG sits in one of the most diverse areas and has this rich tradition of looking at organismal diversity. As a result, this institution is one of the centers of this work,” said Paulay. “We know what we know now fairly well because of a lot of effort done by a lot of people who have documented what they have described.”

Due to climate change, development, pollution, and other factors that contribute to habitat loss, the world is facing a biodiversity crisis. The first step in addressing this issue involves developing an understanding of what lives in the biosphere, the parts of the world where life exists, and how they function.

These scientists, who hail from the United States, Italy, and Japan, held a series of presentations concerning organisms such as mollusks, worms, shrimps, and other invertebrates to increase local research capacity and generate interest in these under-studied fields.

One of the presenters was Florida Museum Curator of Invertebrates Gustav Paulay, Ph.D., who formerly served as the director of the UOG Marine Laboratory.

“It can be disheartening to get into the water after a couple of decades and see what has happened to the reef,” said Paulay.” Some parts are great, some parts not so much. We are going through a biodiversity crisis and one thing that scientists can do about is at least get an idea of what the biosphere is like before it changes any further.”

During his time at UOG, Paulay spent years cataloging the diversity of invertebrates around Guam. The Bioblitz, supported by Guam NSF EPSCoR, was meant to expand the existing knowledge of Guam’s marine ecosystems to inform future management efforts and apply that knowledge to other kinds of studies.

“UOG sits in one of the most diverse areas and has this rich tradition of looking at organismal diversity. As a result, this institution is one of the centers of this work,” said Paulay. “We know what we know now fairly well because of a lot of effort done by a lot of people who have documented what they have described.”

UOG scientists find new marine biological records and species

Following a three-week series of biological surveys, scientists from the University of Guam Marine Laboratory along with an international team of researchers estimate that they have collected hundreds of new marine biological records and species combined from around the coasts of Guam.

From the southern coast of Guam almost up to Ritidian, the researchers surveyed around 50 sites through dives, intertidal walks, and snorkeling from February 2 - 22, 2024 and collected organisms such as crabs, shrimps, worms, and mollusks.

Following a three-week series of biological surveys, scientists from the University of Guam Marine Laboratory along with an international team of researchers estimate that they have collected hundreds of new marine biological records and species combined from around the coasts of Guam.

A Bioblitz is an event focused on finding and identifying as many species as possible in a place over a set period. This Bioblitz was supported by the university’s Guam National Science Foundation EPSCoR grant, which focuses on studying the biodiversity of marine life in Micronesia and how climate change affects the region.

From the southern coast of Guam almost up to Ritidian, the researchers surveyed around 50 sites through dives, intertidal walks, and snorkeling from February 2 – 22, 2024 and collected organisms such as crabs, shrimps, worms, and mollusks.

Over a thousand species were collected. According to UOG Biorepository Curator of Crustacea, Dr. Robert Lasley, an estimated 10 to 15 percent are new species or new records for Guam. A new biological record refers to an organism that has never been recorded within a geographic area.

“The findings from this Bioblitz are a testament to the University of Guam’s status as a premier research hub serving the Micronesian region,” said UOG President Anita

Borja Enriquez. “Through collaboration, dedication, and their commitment to discovery, these researchers have helped uncover the vast biodiversity living in the waters and sands of our island.”

Notable findings from the Bioblitz include:

A new record of a false spider crab found near the UOG Marine Laboratory
71 new records of amphipods, a small shrimp-like crustacean
An estimated 46 new records of ribbon worms
Rare species of mollusks and gobies that live in symbiosis with a shrimp that inhabits underground burrows in the reef flats of Guam

Representatives of each species collected during the Bioblitz will be housed at the Guam NSF EPSCoR Guam Ecosystems Collaboratorium for Corals and Oceans Biorepository, a collection of marine fauna and flora that serves as an archive of the biodiversity found within the Micronesian region.

“After many long nights at the marine laboratory carefully processing specimens, these scientists have contributed immensely to our knowledge of this region’s ecosystems,” said Guam NSF EPSCoR Principal Investigator Dr. Terry Donaldson. “Through the Biorepository, we are able to share these findings with fellow researchers and work together to learn more about the world around us.”

Some specimens may be loaned to other scientists so that they can be examined further. The Biorepository team is partnering with Dr. Christopher Meyer from the National Museum of Natural History at the Smithsonian Institution to get all of the species DNA barcoded for identification.

Due to factors that impact marine ecosystems such as climate change, pollution, changing currents, and development, biological surveys serve as the first step towards preserving these ecosystems and the organisms that call them home.

“Right now, we’re experiencing a biodiversity crisis. We’re losing organisms and species very fast,” said Lasley. “How can you protect what you don’t know exists? It’s important to do this kind of work to capture this baseline data of what organisms are out there and where they live so we can try to build a foundation of knowledge that we can use to protect them.”
