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] Largest ever private award to UH funds microbial oceanography research

boat deck

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 the largest ...

Water in Moon rocks provides clues and questions about lunar history

Pyroclastic glass beads

A recent review of hundreds of chemical analyses of Moon rocks indicates that the amount of water 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 ...

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 ... Read More »

Investigating effects of military munitions disposed of off Pearl Harbor

HUMMA project investigator

On March 29, a full array of state-of-the-art technologies including several owned and operated by University of Hawai‘i at Mānoa School of Ocean Earth Science and Technology (SOEST) will be used in the latest phase of an Army-funded research effort to further investigate sea-disposed military munitions. This research will take place south of Pearl Harbor at an area designated by ... Read More »

Antarctic fjords are climate-sensitive hotspots of diversity

Giant bristle worm

Deep inside the dramatic subpolar fjords of Antarctica, researchers from the University of Hawai‘i at Mānoa have discovered an unexpected abundance and diversity at the seafloor. During a recent expedition, UH scientists for the first time studied the seafloor communities of glacier dominated fjords along the west Antarctic Peninsula, a region undergoing very rapid climate warming. The scientists expected to ... Read More »

An ecosystem-based approach to protect the deep sea from mining

Starfish in deep sea

Five hundred miles southeast of Hawai‘i, in international waters far out of sight of any land, there are vast mineral resources 5,000 meters below the sea. Manganese nodules, rich in commercially valuable mineral resources including nickel, copper, manganese, cobalt and rare-earth elements, overlay a broad swath of the deep-sea floor. It took millions of years to form these deposits. The ... Read More »

A University of Hawaiʻi Sea Grant College Program (UH Sea Grant) article on smart growth and community design in ‘Ewa, Hawaiʻi, is the featured story on the National Sea Grant Office website.  View the full article here. “What we do on land directly impacts the ocean, making sustainable development critical to coastal ocean health,” said Kathryn R. MacDonald, communications specialist in the National ... Read More »

Paths of possible debris from storm surge of super typhoon Haiyan

Paths of possible debris from storm surge of super typhoon Haiyan

Images of the storm surge from super typhoon Haiyan as it struck the city of Tacloban on November 8 awaken memories of the tsunami devastation in Japan a little over 2½ years ago. How much and what kind of debris the storm surge washed into the ocean is not yet known. Should such debris have been generated, however, a large ... Read More »
