Dive discovers missing aircraft hangar of sunken WW II-era Japanese submarine

Pisces V submersible

The dramatic discovery of a lost World War II-era Imperial Japanese Navy mega-submarine by a University of Hawaiʻi and U.S. National Oceanic and Atmospheric Administration (NOAA) team in December 2013 inspired a new search by NHK, the Japanese Broadcasting Corporation, to find key missing pieces of the battleship. The recent survey, the first to return to I-400 submarine since its ... Read More »

Researchers from UH Mānoa and colleagues found that microbial communities in different regions of the Pacific Ocean displayed strikingly similar daily rhythms in their metabolism despite inhabiting extremely different habitats – the nutrient-rich waters off California and the nutrient-poor waters north of Hawai‘i. Furthermore, in each location, the dominant photoautotrophs – light-loving bacteria that need solar energy to help them photosynthesize ... Read More »

UH Professor honored with American Meteorological Society’s highest award

Bin Wang

Bin Wang, professor and former chair of the Department of Atmospheric Sciences at UH Mānoa, was awarded the 2015 Carl-Gustaf Rossby Research Medal by the American Meteorological Society “for creative insights leading to important advances in the understanding of tropical and monsoonal processes and their predictability.” Wang has been with the Department of Atmospheric Sciences (formerly Department of Meteorology) at ...

Research team discovers intact ‘ghost ship’ off the coast of Oahu

The USS Kailua, 1943.

Researchers from the University of Hawai‘i at Mānoa and NOAA’s Office of National Marine Sanctuaries today announced the discovery of an intact “ghost ship” in 2,000 feet of water nearly 20 miles off the coast of Oʻahu.  Sitting upright, its solitary mast still standing and the ship’s wheel still in place, the hulk of the former cable ship Dickenson, later the ...

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 ... Read More »

Another human footprint in the ocean: Rising anthropogenic nitrate levels

boat deck

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 ... Read More »

CT scans of coral skeletons reveal ocean acidity increases reef erosion

Colony of rare corals

Coral reefs persist in a balance between reef construction and reef breakdown. As corals grow, they construct the complex calcium carbonate framework that provides habitat for fish and other reef organisms.  Simultaneously, bioeroders, such as parrotfish and boring marine worms, break down the reef structure into rubble and the sand that nourishes our beaches. For reefs to persist, rates of ... Read More »

Study reveals tiger shark movements around Maui and Oahu

Shark_Tag1_web

UH Mānoa researchers are using tracking devices to gain new insights into tiger shark movements in coastal waters around Maui and O‘ahu. The ongoing study reveals their coastal habitat preferences “We need to understand tiger shark movements in our coastal waters to gain a clearer comprehension of the circumstances bringing sharks and humans together,” said Dr. Kim Holland, senior shark scientist at the ...

EPA grants recognize two grad students working with corals

Colony of rare corals

The U.S. Environmental Protection Agency (EPA) announced $168,000 in fellowship grants to two graduate students at the Hawai‘i Institute of Marine Biology (HIMB). John Burns and Raphael Ritson-Williams were named as recipients of the Science to Achieve Results (STAR) fellowship. Burns’ research will focus on the relationship between land-based sources of pollution and coral reef ecosystem function off the Hamakua ... Read More »
