Aug 18: Symbiotic survival

One of the most diverse families in the ocean today—marine bivalve mollusks known as Lucinidae (or lucinids)—originated more than 400 million years ago in the Silurian period, with adaptations and life habits like those of its modern members. Publishing in Geology, G&G researcher Steven Stanley tracks the remarkable evolutionary expansion of the lucinids through significant symbiotic relationships. The Lucinidae remained at very low diversity until the rise of mangroves and seagrasses near the end of the Cretaceous. Especially important in their diversification was the lucinids’ development of a symbiotic relationship with seagrasses where they took advantage of the oxygen-poor, sulfide-rich sediments below roots and rhizomes.

Aug 12: Moon rocks!

During the “supermoon” of Sunday 10 August the moon was 221,765 miles from Earth, measured center to center, which is the closest the moon will get to our planet this year. Katie Robinson gets a lot closer than that, in a way: she studies moon rocks as a graduate assistant at HIGP. UH has about 120 grams of moon rocks brought here in 1990 for study, and Robinson is investigating the presence of apatite, a mineral that contains water, in the sample. “You get used to working on these tiny little samples …,” she said. “And then you go outside and you look up and you go, ‘Wow, my rocks are from there. My samples are from there. I’m holding moon rocks!’ You kind of remember why you got into it in the first place.”

Aug 11: Atlantic warming source of recent Pacific climate trends

International Pacific Research Center (IPRC) researchers Axel Timmermann and Yoshimitsu Chikamoto partnered with colleagues at the University of New South Wales and University of Hawai‘i to solve the puzzle of why, contrary to climate model projections, observations show that in recent years the Pacific trade winds have strengthened, the eastern Pacific has cooled, and sea level has risen in the western Pacific. The source of these trends, they have found, is rapid warming of the Atlantic Ocean. Their findings from observations and modeling experiments are published in an online issue of Nature Climate Change.

Aug 06: Ocean expedition maps Lō‘ihi’s deepest reaches

The Lō‘ihi Seamount is an active underwater volcano just over a half-mile below the ocean’s surface, 21 miles southeast of the island of Hawai‘i. Now there is a greater understanding of the youngest volcano in the Hawaiian island chain, and the role submerged volcanoes play in Earth’s history, after a scientific expedition in the summer of 2014 led by SOEST researchers aboard Schmidt Ocean Institute’s R/V Falkor. “Lō‘ihi is a very wonderful natural laboratory in our backyard for studying earth processes that have happened in the past,” said Brian Glazer, associate professor of oceanography. “So while today, Lō‘ihi might be unique, there are times in Earth’s history that much of the global ocean looked like Lō‘ihi does today.”

Aug 04: Invasive lionfish likely safe to eat after all

Scientists have learned that recent fears of lionfish causing ciguatera poisoning, caused by toxins produced by single-celled dinoflagellates that reef fish sometimes eat, may be unfounded. If so, current efforts to control invasive lionfish by fishing derbies and targeted fisheries may remain the best way to control them. A new study published in Environmental Biology of Fishes may have an explanation for why, although lionfish often test positive for the toxin, as of July 2014 there are no known cases of ciguatera from eating them. Lead author Christie Wilcox of HIMB thinks it may be because venom proteins in the fish might act as toxin mimics. The fish’s proteins degrade with cooking, making them safe to eat, while ciguatoxins do not.

Jul 29: New research reveals vog’s effects on Hawai‘i’s weather

One might assume that a tropical storm moving through volcanic smog (vog) would sweep up the tainted air and march on, unchanged. However, a recent study from atmospheric scientists at SOEST revealed that although they are microscopic, gasses and particles from Kilauea volcano exerted an influence on Tropical Storm Flossie — affecting the formation of thunderstorms and lightning in the sizable storm. “We have a lightning detection network. We found when the vog plume was entrained in the deep clouds associated with Flossie, there was a great enhancement of lightning,” said professor Steven Businger, co-author with graduate assistant and lead author Andre Pattantyus of the paper in Geophysical Research Letters.

Jul 25: False killer whale helps study of hearing, echolocation

A pseudorca (Pseudorca crassidens), also called a false killer whale, is helping scientists at the Hawai‘i Institute of Marine Biology (HIMB) on Coconut Island with some very important research. Scientists say Kina is friendly, patient and incredibly smart — and the only false killer whale in the world dedicated to research. “We primarily look at the hearing and echolocation of dolphins and whales. We are really interested in how the animals hear and how they’re affected by loud sounds,” said Paul Nachtigall, director of the HIMB’s Marine Mammal Research Program (MMRP).

Jul 18: PacIOOS wave buoy in Majuro helps keep islanders safe

For people living on Majuro Atoll in the Republic of the Marshall Islands (RMI), if the ocean swell is too high, the safety of fishermen transiting out of the lagoon to open waters is threatened, homes and businesses may be flooded with seawater, roadways may become impassable, and even the runway strip at the airport may be rendered useless for large commercial aircraft. On 10 July 2014, the Pacific Islands Ocean Observing System (PacIOOS) collaborated with partners to deploy a new Datawell Directional Waverider buoy named “Kalo” about one mile off the eastern shore of Majuro to provide a data stream of wave height, wave direction, wave period, and sea surface temperature every 30 minutes.

Seawater overtopping roadways or flooding homes and businesses in low-lying communities can threaten the public health and safety of Pacific Islanders. A team of physical oceanographers, including Oceanography postdoctoral researcher Martin Guiles and Oceanography professor Doug Luther, working with Pacific Islands Ocean Observing System (PacIOOS) has developed new tools to forecast potential inundation events so that affected communities can better prepare and respond to such threats days in advance. The forecast models are called the PacIOOS Six-Day High Sea Level Forecasts and the most recent developments include Apra Harbor in Guam and Malakai in Palau.

Jul 11: Ocean’s most abundant organisms have daily cycles

Communities of ocean microbes have their own daily cycles, and they are not all about the sun. Photoautotrophs — bacteria that use solar energy to help them photosynthesize food — have been known to sun themselves on a regular schedule. But in a new study published in the journal Science, researchers working at Station ALOHA, a deep ocean study site 100 km north of O‘ahu, observed different species of free-living, heterotrophic bacteria turning on diel cycling genes at slightly different times, suggesting a wave of transcriptional activity that passes through the microbial community each day. Oceanography professor and C-MORE co-PI and co-director Ed DeLong was head of the MIT team that made this discovery.

Jul 10: Whales revealed as marine ecosystem engineers

A paper in Frontiers in Ecology and the Environment evaluates decades of research on the ecological role of great whales. The researchers suggest that the influence of these animals have been substantially undervalued because scientists have underestimated the degree to which the decline in whale population has altered marine ecosystems. The paper summarizes a strong body of evidence indicating that whale recovery “could lead to higher rates of productivity in locations where whales aggregate to feed and give birth,” supporting robust fisheries. Oceanography professor Craig Smith, one of the co-authors, is an expert on the ecological importance of “whale falls” —  whale carcasses on the sea floor.

Jul 09: Four scalloped hammerhead shark populations at risk

Oceanography professor Dave Karl talked with Hawaii Public Radio’s “The Conversation” about a newly completed world-wide ocean survey that, surveying the major midocean gyres, found 99% less ocean plastic in the open water than researchers expected to document. There's speculation that the missing plastic bits may have found their way to the bellies of fish and possibly, ours. Karl is the director of the Inouye Center for Microbial Oceanography: Research and Education (C-MORE) and co-director of the Simons Collaboration on Ocean Processes and Ecology (SCOPE).

Jul 08: Dave Karl on ocean plastic mystery

The National Marine Fisheries Service (NMFS) has classified as endangered and threatened four distinct populations of scalloped hammerhead sharks, a species whose fins are favored in shark fin soup. The central Pacific population, which includes animals living in Hawai‘i’s waters, is considered fairly healthy and isn’t being listed. Carl Meyer, assistant researcher at the Hawai‘i Institute for Marine Biology (HIMB), said demand for the scalloped hammerhead fins is driving overfishing of the species because the high number of fibers in the fins makes them particularly desirable. They’re better off in Hawai‘i in part because there isn’t a market for sharks as a commercial species in the islands, said Kim Holland, also a researcher at HIMB.

Jul 03: Mysterious substance appearing at beaches: “Tricho”

A mysterious brown substance — a Trichodesmium algae bloom — recently appearing at beaches across Hawai‘i caused state health officials to issue a brown water advisory for Kaua‘i. Oceanography research associate Eric Grabowski talks about the unusual concentration of the algae, nicknamed ”Tricho”, with the same passion that miners talk about gold. “Because it’s not often that we see organisms that thick in the oligotrophic ocean, so it was pretty exciting to come upon this,” he said. Oceanography associate professor Matthew Church said the Tricho bloom plays an important role in our ocean ecosystem. “It captures nitrogen from the atmosphere and introduces it to the ocean water… it helps fertilize the waters around Hawai‘i.”

Jul 02: Searching for History

The July-August 2014 issue of The Military Engineer reports on the multi-phase program known as the Hawaii Undersea Military Munitions Assessment (HUMMA) currently undertaking the unique challenge of characterizing a historic deep-water military munitions disposal site. From its start in 2006 through today, HUMMA has faced several unusual challenges, including an extremely large study area that is in perpetual darkness; complex safety and logistical requirements; and scarce information about the site history, leaving few appropriate benchmarks for investigation design and data evaluation. Margo Edwards, senior research scientist at Hawaii Institute of Geophysics and Planetology (HIGP) is HUMMA’s principal investigator.

Jul 01: Mesoscale eddies move far more water than thought

Researchers from the Ocean University of China and the UH Dept. of Oceanography have found that mesoscale eddies — spinning masses of water 50 to 300 miles in diameter that travel westward in the subtropics —  appear to carry far more water with them than scientists have previously imagined. Scientists have known about them for quite some time, but till now, very little was known about their size and movements. To find out more, the researchers analyzed data from both satellites and submersible probes. Putting all the data together, the team was able to see that such eddies can live for months, or even years. Oceanography professor Bo Qiu is one of the authors of the paper published in the journal Science.

Jun 30: New kind of meteorite “ancient asteroid destroyer”?

For 50 years, scientists have wondered what annihilated the ancestor of L-chondrites, the roof-smashing, head-bonking meteorites that frequently pummel Earth. Now, a 470-million-year-old fossil meteorite discovered in a southern Sweden limestone quarry may finally solve the mystery, scientists report in the journal Earth and Planetary Science Letters. The strange new rock may be the missing “other half” from one of the biggest interstellar collisions in a billion years. “Something we didn't really know about before was flying around and crashed into the L-chondrites,” said study co-author Gary Huss, a researcher at the Hawai‘i Institute of Geophysics and Planetology (HIGP).

“It’s definitely the last frontier on the planet,” said Jeffrey Drazen, an associate professor of Oceanography. He was a participant in a research cruise led by Woods Hole Oceanographic Institution (WHOI) to the Kermadec Trench off the northeastern tip of New Zealand’s North Island — the fifth deepest trench in the world with a depth of 6.2 miles. The goal of the expedition, known as the Hadal Ecosystem Studies or HADES, was to study creatures that have adapted to the extreme pressure, temperatures around 34°F, and highly variable food supplies. “Some of these animals may have compounds that they use to deal with pressure that can be very important to industrial or bio-medical applications…,”  Drazen said.

Jun 27: Fostering Hawai‘i’s young marine scientists

On Thursday 19 June 19, 2014 11 UH marine science students returned from the last of three research expeditions aboard Schmidt Ocean Institute’s R/V Falkor. The group sailed to Station ALOHA, a long-term ocean sampling site 60 miles north of O‘ahu with chief scientist Oceanography assistant professor Erica Goetze. This makes a total of 58 undergraduate and graduate students who have had an opportunity to learn and train on board the R/V Falkor in 2014. One element that makes this cruise unique is the varied career levels of scientists on board: while student research projects were the focus of the expedition, Brian Taylor, Dean of SOEST, joined the cruise to map the seafloor between the islands of O‘ahu and Moloka‘i.

Jun 26: New understanding could aid climate change forecasts

The passageway that links the Pacific Ocean to the Indian Ocean is acting differently because of climate change, and now its new behavior could, in turn, affect climate in both ocean basins in new ways. James Potemra, HIGP associate specialist and manager of the IPRC”s APDRC, is a co-author of the study published in the 22 June 2014 online issue of Nature Geoscience. The scientists have found that the flow of water in the Indonesian Throughflow – the network of straits that pass Indonesia's islands – has changed since the late 2000s under the influence of dominant La Niña conditions. This could in turn affect climate in both ocean basins in new ways.

Through 07 July 2014, SOEST researchers are leading an expedition to Lō‘ihi Seamount, southeast of the island of Hawai‘i, whose base remains largely unexplored. Brian Glazer, lead scientist and associate professor of Oceanography, and his team will map the Seamount’s deeper reaches aboard the Schmidt Ocean Institute’s R/V Falkor using the Woods Hole Oceanographic Institution (WHOI)’s Sentry AUV. They will also collect water column samples and explore Lō‘ihi’s extraordinarily thick mats of iron-oxidizing bacteria, which are able to use iron as an energy source and create rust in the process. Processes at Lō‘ihi could be an important component in the Pacific Ocean’s iron and carbon cycling, Glazer said.

Jun 23: Re-evaluation of size of white shark population

Oceanography associate specialist and PFRP manager Kevin Weng is a co-author of a new study published in the journal PLoS ONE (PDF) suggesting there are around 2,000 white sharks in the eastern North Pacific, not a mere 219 as research released three years ago had indicated. The earlier count was based on research at two sites — the Farallon Islands west of San Francisco, and nearby Tomales Point — where seals congregate, as do the sharks that eat them. Since sharks are difficult to count, and populations were so fluid at those two sites, researchers widened their research scope to include other known gathering spots from Mexico into British Columbia and Alaska, and accounted for all life stages of the animals.

Jun 23: Federal $3M grant for hydrogen energy research

The U.S. Department of Energy is awarding a $3 million grant to the Hawai‘i Natural Energy Institute (HNEI) to help fund ongoing research on the development of photo-electro-chemical (PEC) technologies. Also known as “Artificial Photosynthesis”, this technology combines advanced photovoltaic (PV) materials and catalysts into a single device that uses sunlight to split water into molecular hydrogen and oxygen. The “solar fuels” produced with this method can be stored, distributed and finally recombined into a fuel cell to generate electricity, with water as the only byproduct. This multi-disciplinary research program is led by assistant researcher Nicolas Gaillard at HNEI’s Thin Films Laboratory.

Jun 16: Plastic-eating fish raise concerns about food toxicity

Looking at slides of plastic collected from fish stomachs, Oceanography professor Jeffrey Drazen discusses the debris found. “Each panel represents the pieces found in an individual fish. So these are the pieces found in a lancet fish. These are in an opah.” Opah have the heartiest appetite for plastic, which was found in 60 percent of the animals. A new UC Davis study magnifies concerns about the hazards of ingesting marine debris. “The most interesting thing these recent studies show is these plastics are sponges” for other contaminants, explains Drazen. “It’s not just worrying about eating the plastic and blocking the stomach. They’re vectors and they’re adding contaminants to fishes in the ocean.”

Jun 13: New model predicts Ala Wai Canal brown water runoff

The first evidence for massive and abrupt iceberg calving in Antarctica, dating back 19,000 to 9,000 years ago, has been documented by an international team of geologists and climate scientists. Their findings are based on analysis of new, long deep sea sediment cores extracted from the region between the Falkland Islands and the Antarctic Peninsula. IPRC and Oceanography professor Axel Timmermann is a co-author of the study published in the 28 May 2014 issue of Nature bearing witness to an unstable Antarctic ice sheet that can abruptly reorganize Southern Hemisphere climate and cause rapid global sea level rise.

A recent review of hundreds of chemical analyses of Moon rocks indicates that the amount of water trapped in volcanic glasses or chemically bound in mineral grains inside lunar rocks in the Moon’s interior varies regionally — revealing clues about how water originated and was redistributed in the Moon. These discoveries provide a new tool to unravel the processes involved in the formation of the Moon, how the lunar crust cooled, and its impact history. The paper by HIGP / G&G / UH NASA Astrobiology Institute (UHNAI) graduate student Katie Robinson and HIGP researcher Jeff Taylor, was published in Nature Geoscience.

May 23: Trade winds getting blocked later than usual

Satellite screens show a low-pressure system taking a bite out of our trade winds. National Weather Service (NWS) Meteorologist Robert Ballard said it’s a bit unusual to have this happening at this time of year. “For this late in the season, it’s a long stretch without trades,” he said. “What we’re seeing right now is more of a winter time or wet season pattern.” Any trade wind interruption makes it onto the radar of Meteorology professor and state climatologist Pao-Shin Chu, who said the state averages per year about 240 to 250 days with Northeast trades, but that history shows a pattern: “On average we are losing about one trade wind day per year,” he said. Chu said over the next several years, the number of trade wind days may continue to decrease.

May 16: Precursor volcano to the island of O‘ahu discovered

SOEST researchers, led by Geology emeritus professor John Sinton, and colleagues recently discovered that O‘ahu actually consists of three major Hawaiian shield volcanoes, not two, as previously thought. Extending almost 100 km from Ka‘ena Point, the western tip of the island of O‘ahu, is the submarine Ka‘ena Ridge, an area now recognized to represent a precursor volcano to the island. About 5 million years ago, Ka‘ena emerged from the seafloor and later provided the base upon which Wai‘anae and Ko‘olau volcanoes formed.

May 12: Super corals used to create “designer” reefs

Scientists say corals are dying at an alarming rate, with countless diseases taking their toll. The race is on to reverse that trend. “If one is going to design an intervention and what we are suggesting is an intervention this is the time to do it. While you still have biological material to work with,” said the head researcher, Ruth Gates, a tenured researcher at the Hawaii Institute of Marine Biology (HIMB). Gates and a team of marine biologists are putting years of science to the test and breeding corals on Coconut Island. The goal, they said, is to create super “designer” corals that will be better fit to survive any environmental changes, such as increased temperature and acidity, ahead. They stress it is not a GMO reef.

May 09: Tsunami taught valuable lessons on debris movement

Japan’s 11 March 2011 earthquake and tsunami were unmitigated disasters with far-reaching effects that continue to be felt by many people. However, they also presented a unique opportunity for researchers to learn how wind and currents interact to push debris across the Pacific ocean. “The strongest contribution, the most important thing we learned from the tsunami, is the effect of the wind on debris,” said IPRC scientific computer programmer Jan Hafner, who worked with principal investigator Nikolai Maximenko on the debris movement models. Now, researchers say their window to learn from the disaster might be closing.

May 08: Partnership demonstrates fuel cells for He recovery

Hawai‘i Natural Energy Institute (HNEI), together with Sierra Lobo Inc., has demonstrated the recovery of high-purity helium from hydrogen/helium mixtures produced at rocket engine testing sites using proton-exchange-membrane fuel cells. “HNEI optimized proton-exchange-membrane fuel cell technology to electrochemically separate the two gases,” explained HNEI director Richard Rocheleau. Separation was achieved by applying electrical energy to the fuel cell, rather than using it to produce energy.

Apr 30: Deep origins to the behavior of our volcanoes

Kīlauea volcano, on the Big Island of Hawai‘i, typically has effusive eruptions, wherein magma flows to create ropy pāhoehoe lava, for example. However, Kīlauea less frequently erupts more violently, showering scoria and blocks over much of the surface of the island. To explain the variability in Kīlauea’s eruption styles, a team including Bruce Houghton, the Gordon Macdonald Professor of Volcanology in Geology and Geophysics (G&G), colleagues from the University of Cambridge (UC), and Don Swanson from the Hawaiian Volcano Observatory (HVO) of the U.S. Geological Survey (USGS) analyzed 25 eruptions that have taken place over the past 600 years.

Apr 22: Scientific mission explores one of the deepest trenches

Jeffrey Drazen, an Oceanography Associate Professor, joins an international team of researchers to use the world's only full-ocean depth, hybrid remotely operated vehicle, WHOI’s Nereus, and other advanced technology to explore life in the depths of the Kermadec Trench. The 40-day expedition, which began on 12 April 2014, kicks off an ambitious three-year collaborative effort funded by the National Science Foundation (NSF). The Kermadec Trench, off the northeastern tip of New Zealand’s North Island, is the fifth deepest trench in the world with a maximum of depth of 10,047 meters (32,963 feet or 6.24 miles). It is also one of the coldest trenches due to the inflow of deep-water originating from Antarctica.

Apr 21: Charting the seafloor of Papahānaumokuākea MNM

On 11 April 2014, scientists returned from a 36-day mapping expedition to Papahānaumokuākea Marine National Monument (PMNM) in the remote Northwestern Hawaiian Islands. PMNM is the largest protected area in the United States, encompassing an area greater than all its national parks combined, yet over half its seafloor has never been mapped in detail due to the limited availability of the advanced sonar systems required. The survey, carried out aboard the Schmidt Ocean Institute’s (SOI) 272-foot R/V Falkor, mapped over 40,000 square kilometers (15,445 square miles) of previously unmapped or poorly mapped areas inside the Monument. This represents approximately 11 percent of the total area of PMNM.

Apr 14: IPRC and Meteorology scientists warn of “big El Niño”

A huge mass of warm water churning across the tropical Pacific points to the development of a periodic phenomenon that typically brings destructive weather across far reaches of the planet, two SOEST scientists warn. Axel Timmermann, a professor of Oceanography with the International Pacific Research Center (IPRC), says, “I would say there is an 80 percent chance that a big El Niño will develop by the end of the year.” In agreement is Fei-Fei Jin, a professor of Meteorology. “Most people are still cautious, but we have a bunch of experts here on the campus who have been very watchful of this for over a month and we are thinking it could be a pretty serious one.” In Hawai‘i the results could mean a dry winter and wet summer, forecasters say.

Apr 08: Niijima Island merges with older neighbor

NASA’s Earth Observatory reports that Niijima island, a volcano which broke through the ocean’s surface last November, has now merged with nearby Nishinoshima island, which formed 40 years ago. The new island is about a kilometer (six-tenths of a mile) across and 60 meters (almost 200 feet) above sea level at its highest point. At its size in December, the new island was expected to last several years, according to Japanese scientists. Because it has continued to grow, it could last much longer. “A lot of it depends on how fast it erodes,” Ken Rubin, Geology & Geophysics (G&G) professor and expert in deep submarine volcanism, told CNN after the island broke the surface last year. “Until it shuts off, it’s too soon to tell.”

A new space odyssey began on Friday 28 March 2014 as the six crew members of the new Hawai‘i Space Exploration and Analog Simulation (HI-SEAS) mission entered their remote habitat on the first night of a four-month-long journey. Using surveillance cameras, electronic surveys, crew member diaries, and other sources, researchers will be keeping an eye on the crew. Researchers are tracking group cohesion and a wide range of cognitive, social, and emotional factors. They are particularly interested in how technical, social, and task roles within the group evolve over time and how they affect performance. Kim Binsted, ICS associate professor and G&G grad student, is principal investigator for HI-SEAS.

Apr 02: Officials aim to prevent landslides in Hawai‘i

As of Monday 31 March the death toll from the Stillagumish River, WA, landslide had grown to 24, with another 22 people missing. KHON2 wondered if something like that could happen in Hawaii, so turned to Geology & Geophysics (G&G) professor Steve Martel. He says while the topography and soil conditions need to be taken into consideration, all you need is one trigger, and lots of it, to cause a landslide. Martel referenced the Makaha Valley disaster of 1996 as an example, when boulders, water, and mud cascaded down the mountain. That landslide, and a couple of flooding events since, have attracted the attention of officials, and a study has been initiated in the effort to prevent another disaster in the region.

Apr 01: Tsunami advisory issued, but no major threat seen

Pacific Tsunami Warning Center (PTWC) officials in Honolulu issued a tsunami advisory for the islands, saying that while a major seismic wave is not expected, sea-level changes and strong currents may occur starting early Wednesday morning. The advisory comes after a magnitude-8.2 quake struck off the coast of Chile that sent tsunami of more than six feet to Chilean coastal cities. “Based on all available data a major tsunami is not expected to strike the state of Hawai‘i. However, sea level changes and strong currents may occur along all coasts that could be a hazard to swimmers and boaters as well as to persons near the shore at beaches and in harbors and marinas,” the advisory said. The threat may continue for several hours after the initial wave arrival at about 3:24 am, officials said.

Scientists are revisiting previously-found munitions dumped at sea to determine whether the materials still pose a threat to human health and the environment. In 2007, UH was awarded money to conduct the Hawaii Undersea Military Munitions Assessment (HUMMA) in response to KHON2’s “Buried at Sea” series, which uncovered the dumping of thousands of military munitions decades ago just off the Waianae coast. “Specifically, we’re looking for mustard agent,” said HIGP researcher and CIMES director Margo Edwards. “The message that I want to get out is the fact that we are detecting mustard in the sediments about two meters around these munitions.”

Medical officials in Hawai‘i are seeing an influx of patients complaining of year-round allergies with no relief in sight. Many of the cases share a cause-and-effect relationship with volcanic smog — primarily a mixture of sulfur dioxide (SO2) gas and sulfate (SO4) aerosol — also known as “vog.” Geology & Geophysics (G&G) researchers Kevin Johnson and Thomas Shea, and Meteorology professor Steven Businger, director of the Vog Measurement and Prediction Project (VMAP), discuss the on-going volcanic eruption at Kīlauea on Hawai‘i Island, the composition of the haze, and the effects on the comfort and health of Hawai‘i’s residents and visitors.

Mar 27: 9.2 earthquake changed thinking about tsunamis

The great Alaska earthquake of 27 March 1964, with a magnitude of 9.2, was and remains the largest quake ever recorded in the United States and the second largest anywhere, beaten only by the 9.5 quake in Chile in 1960. This megaquake not only devastated a vast swath of south-central Alaska, killing 131 people and causing $2.3 billion in damage (in today’s dollars), it shook up scientific notions about how great quakes are generated, affirming the then-still-novel theory of plate tectonics. Ocean and Resource Engineering (ORE) professor Kwok Fai Cheung, Pacific Tsunami Warning Center (PTWC) scientist Gerard Fryer, and Hawai‘i Institute of Geophysics and Planetology (HIGP) interim director Rhett Butler are interviewed.

Mar 18: Strong El Niño events leading to lower local sea levels

During very strong El Niño events, sea level drops abruptly in the tropical western Pacific and tides remain below normal for up to a year in the South Pacific, especially around Samoa. The Samoans call the wet stench of coral die-offs arising from the low sea levels taimasa (pronounced [kai’ ma’sa]). The international study to uncover the reasons for this phenomenon and its climate effects was spearheaded by International Pacific Research Center (IPRC) postdoctoral fellow Matthew Widlansky and was recently published in the Journal of Climate.

Mar 10: Station ALOHA: A laboratory for studying the sea

“Aloha” is the Hawaiian word for love and affection, commonly used alone or in phrases of fond greeting or farewell. Sixty miles north of O‘ahu, at a lonely spot in the Pacific Ocean, the word has a different meaning: “A Long-term Oligotrophic Habitat Assessment.” This year marks 25 years since Oceanography professors David Karl and Roger Lukas established Station ALOHA in a 6-mile-radius circle centered at 22° 45' N, 158° W. Since then, the remote outpost has become legendary: as part of the Hawaiian Ocean Time-series program (HOT) it has offered up an invaluable long-term record of the chemistry and biology found at a typical deep spot in the subtropical North Pacific.

Mar 07: HIMB researcher sees oceans growing too acidic

On Coconut Island, Ruth Gates is in her own race against time. The Hawai‘i Institute of Marine Biology (HIMB) researcher sees the oceans growing too acidic, too quickly for many marine species to handle the change. Without drastic steps to curb man-made carbon emissions, they say, many coral reefs that support fisheries, protect coast lines from storm surge, and attract tourists will dwindle and disappear in the coming decades. “We can confirm that reefs are declining. There‘s no disputing that,” Gates said. “But it's not all doom and gloom.” Gates has spent the past several years scrambling to find the hardiest, strongest coral that can endure the warmer and more acidic seas of the future.

Mar 07: Scientists urge lawmakers to protect Hawai‘i’s ‘opihi

Experts want Hawai‘ lawmakers to update regulations meant to protect ‘opihi, a tasty mollusk whose numbers have crashed in parts of the state. Biologists with the Hawai‘i Institute of Marine Biology (HIMB) told a House panel on Wednesday that stocks of the ocean snails off Oahu's shores are at dire lows. But with better management, they said, O‘ahu’s ‘opihi can make a comeback and other islands’ stocks can be protected. Chris Bird, a researcher with HIMB and an assistant professor at Texas A&M University — Corpus Christi (TAMUCC) and HIMB associate researcher Rob Toonen said size regulations meant to safeguard ‘opihi are failing in part because different varieties reach sexual maturity at very different sizes.

Mar 06: How deep can a fish go? Scientists may have answer

Oceanography associate professor Jeff Drazen is a co-author on a paper published in the Proceedings of the National Academy of Sciences (PNAS) that may explain why fish are not found in the deepest parts of the ocean. Working with translucent hadal snailfish caught at a depth of 4.3 miles, researchers measured levels of a molecule, trimethylamine oxide, that helps protect proteins under pressure (and gives fish their distinctive odor). There appears to be a natural limit to the amount of it a fish can contain and, as a result, scientists say they’ve concluded that fish likely can't survive below about 5.1 miles. That would mean no fish at all live in the deepest one-quarter of the world’s oceans.

The famed “blueberry” rocks discovered on Mars by NASA’s Opportunity rover are not geological evidence of ancient water on the red planet, HIGP researchers Anupam Misra, Tayro Acosta-Maeda, Ed Scott, and Shiv Sharma now argue. Instead, they propose in a paper in Planetary and Space Science that the tiny spherules are actually remnants of small meteorites that broke up in Mars’ atmosphere. “None of the physical properties of the spherules match the concretion model,” says lead author Misra. “But the meteorite theory explains all of their properties.” The biggest issue with the concretion model is the narrow range of spherule size, he adds.

Some of the earliest science fiction imagined voyages to the Red Planet. We now have the space-faring technology, and getting humans to Mars actually seems within reach. There are, of course, many concerns about sending people to Mars, so in preparation researchers are conducting experiments at sites built to simulate these long-duration missions. Kim Binsted (ICSD, UHNAI, and G&G) is principle investigator of one of those programs: Hawai‘i Space Exploration Analog and Simulation (HI-SEAS) on the bare rocky slopes Mauna Kea on the island of Hawai‘i. In a 1,000-sq-ft geodesic dome, six scientists live and work for months. And, simulating working conditions on Mars, the crew can only go outside in mock spacesuits.

Jan 21: Surge in shark attacks causes alarm in Hawai‘i

In 2013, there were 14 shark attacks in the waters around Hawai‘i, eight off the coast of Maui alone, including two fatalities. Although some speculate that there may be something to do with the recovery of the sea turtle population or the Japanese tsunami, there's no evidence to support those ideas. Carl Meyer, Hawai‘i Institute of Marine Biology (HIMB) assistant researcher, points out that one of the more reasonable explanations is simply the increase of people in the water. He notes that there are more kayak fisherman, kite surfers, and paddle boarders than a few decades ago, and a new study he’s leading will look at whether tiger sharks are more prevalent in areas of Maui where those sports are most popular.

Jan 15: HNEI installs PV systems at public schools

As part of ongoing energy efficiency and solar research being conducted by the Hawai‘i Natural Energy Institute (HNEI), six solar photovoltaic (PV) arrays totaling 15 kW in capacity were recently installed in Hawai‘i. Three “net zero energy” (NZE) buildings created by California-based Project Frog Inc. are the most recent experimental platforms used for PV performance research being conducted by the Institute. HNEI director Richard Rocheleau said, “These installations are part of a larger HNEI research endeavor to evaluate and compare the performance of traditional and emerging PV materials and inverter technologies.”

Jan 15: Palmyra atoll trove of research vital to Hawai‘i’s future

Conservationists say it‘s time that Palmyra atoll, a national marine monument, becomes better known for its current role as a living laboratory that can unlock some of the environmental mysteries keeping scientists up at night. The science being done on the atoll, they say, holds valuable lessons for Hawai‘i, especially when it comes to understanding sharks, preserving coral reefs, and combating invasive species. Nature Conservancy science specialist Kydd Pollock noted that Hawai‘i Institute of Marine Biology (HIMB) assistant researcher Greta Aeby’s innovative work at the atoll into stopping the spread of coral disease ultimately could be used in Hawai‘i to stop outbreaks in Kāne‘ohe Bay and areas off Kaua‘i and Maui.

Jan 13: Experts urge lawmakers to address climate change

As they appealed to lawmakers to take action now to protect the state’s irreplaceable resources, experts painted a sobering picture of Hawai‘i’s future in the face of projected climate change, using models depicting Waikīkī and Honolulu slipping under water. “We might expect and plan for one foot of sea level rise by the year 2050 and one meter or three feet of sea level rise by the year 2100,” explained Dolan Eversole of the UH Sea Grant College Program. While there’s little we can do to mitigate climate change without major reductions to greenhouse gas emissions, it’s not too late to adapt to the expected impacts by designing and building our communities to be safer, urge scientists.

Jan 08: HURL enables discovery of long-term ecosystem shift

The Hawai‘i Undersea Research Laboratory (HURL) has enabled scientists to determine that a long-term shift in nitrogen content in the Pacific Ocean has occurred as a result of climate change. Researchers from the Lawrence Livermore National Laboratory (LLNL) and the University of California – Santa Cruz (UCSC) analyzed deep-sea corals gathered near the Hawaiian Islands using the HURL Pisces V, submersible. They observed overall nitrogen fixation in the North Pacific Ocean has increased by about 20 percent since the mid 1800s and this long-term change appears to be continuing today, according to a study published recently in the journal, Nature.

Jan 08: Fast-moving erosion threatens Hawai‘i coastal homes

The large Christmas 2013 swell damaged at least five oceanfront properties on the North Shore of O‘ahu, rekindling the debate about how state officials and homeowners should best respond to beach erosion and the rising waters of the Pacific Ocean. Some property owners want to be able to install a seawall, or something similar, to protect their property. Coastal geologist Charles “Chip” Fletcher, professor of G&G and SOEST’s Associate Dean of Academic Affairs, said building seawalls always comes to mind wherever severe erosion occurs, but that studies show seawalls built on chronically eroding shorelines like Sunset Beach will only lead to more erosion down the coast.

Jan 08: Under the surface with HURL

Not too many people know their office equipment as well as Terry Kerby knows his. He spends five months every year taking his apart and then putting it back together, piece by piece. Then again, not too many people rely on their gear to survive at more than 6,000 feet below the ocean's surface. Kerby is chief pilot at the Hawai‘i Undersea Research Laboratory (HURL), commanding its two submersible vehicles, the Pisces IV and the Pisces V, to explore the depths of the ocean. It's a position that gives him “a big rush, like it's the first time,” every time he dives, yet the danger involved is enough to generate chills as well.

Jan 08: Heavier debris finds isle shores

Since September, there's been a “dramatic” turn in the tsunami debris washing ashore in the Aloha State, scientists say. International Pacific Research Center (IPRC) researchers monitoring that debris say objects such as boats, buoys, and lighter materials are being replaced with a steady stream of heavier wooden beams and planks. The wood appears to be lumber that was used for homes, buildings, and telephone poles. “So far, we have opinions that yes, these objects are from Japan,” said IPRC senior researcher Nikolai Maximenko.

Jan 07: Batteries put to test in photovoltaic plan

Hawaiian Electric Co. (HECO) and the Hawai‘i Natural Energy Institute (HNEI) are launching a project in a West O‘ahu neighborhood to see whether battery technology can be effectively used to open the utility’s grid to greater amounts of solar power produced by rooftop photovoltaic panels. The project, in a neighborhood with one of the island’s highest concentrations of PV panels, is among three ventures being undertaken by HECO and HNEI statewide, investigating how battery technology can be used to overcome limits on the amount of intermittent renewable energy the state’s electric utilities can accept.
