Deep sea sharks are buoyant

Shark with tag

Scientists from the University of Hawaiʻi at Mānoa and University of Tokyo revealed that two species of deep-sea sharks, sixgill and prickly sharks, are positively buoyant—they have to work harder to swim downward than up and they can glide uphill for minutes at a time without using their tails. Their results were published in a recent study,“Unexpected Positive Buoyancy in ...

[VIDEO] Fast-Fill hydrogen fueling station enabling zero emission transportation

Hydrogen filling station

The Hawai‘i Natural Energy Institute (HNEI) has commissioned a “Fast-Fill” high-pressure hydrogen fueling station at the Marine Corps Base Hawai‘i (MCBH), Kaneohe Bay. This state-of-the-art station was developed to support a fleet of General Motors Equinox Fuel Cell Electric Vehicles (FCEV) leased by the Office of Naval Research for use by Marine Corps and Navy personnel on O‘ahu. Operational since ...

Comet Wild 2: A window into the birth of the solar system?

Comet Wild 2

Our solar system, and other planetary systems, started as a disk of microscopic dust, gas and ice around the young Sun. The amazing diversity of objects in the solar system today—the planets, moons, asteroids and comets—was made from this primitive dust. NASA’s Stardust mission returned to Earth with samples of comet Wild 2, a comet that originated outside the orbit ...

Climate researchers discover El Nino’s fueling effect on intense hurricanes

Typhoon Vicente

El Niño, the abnormal warming of sea surface temperatures in the Pacific Ocean, is a well-studied tropical climate phenomenon that occurs every few years. It has major impacts on society and Earth’s climate – inducing intense droughts and floods in multiple regions of the globe. Further, scientists have observed that El Niño greatly influences the yearly variations of tropical cyclones ...

Another human footprint in the ocean: Rising anthropogenic nitrate levels

Human-induced changes to Earth’s carbon cycle – for example, rising atmospheric carbon dioxide and ocean acidification – have been observed for decades. However, a study published this week in Science showed human activities, in particular industrial and agricultural processes, have also had significant impacts on the upper ocean nitrogen cycle. The rate of deposition of reactive nitrogen (i.e., nitrogen oxides ...

Hunting monsters…with sound

Infrasound data

UH Mānoa’s Milton Garces has contributed a new essay to the Sounding Out blog’s “Hearing the Unheard” series.  The story highlights Garces’ research work in infrasound, low-frequency sounds in the atmosphere that are inaudible to the human ear, but can carry for thousands of kilometers.  Infrasound has a variety of important and practical applications including its use in detecting secret missile ...

Researchers embarking on extraordinary expedition to Loihi Seamount

R/V Falkor

UH Mānoa is leading an expedition to Loihi Seamount, southeast of the island of Hawai‘i, whose base remains largely unexplored. Dr. Brian Glazer, lead scientist and Associate Professor of Oceanography, his team from UHM, and colleagues from the University of Minnesota, IFREMER Centre de Brest and Woods Hole Oceanographic Institution (WHOI), will map the Seamount’s deeper reaches using WHOI’s Sentryautonomous underwater ...

[VIDEO] Simons Foundation funds UH microbial oceanography research

For decades now, the University of Hawaiʻi at Mānoa has been at the forefront of microbial oceanography—the study of microscopic organisms, or microorganisms, in the sea. Because of the cutting edge research done at the university’s School of Ocean and Earth Science and Technology and C-MORE, the Center for Microbial Oceanography: Research and Education, UH Mānoa was awarded one of ...
