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 »

Advanced Light Source evidence confirms combustion theory

soot formation

Researchers at UH Mānoa have published the first direct experimental evidence for the validity of a fundamental reaction mechanism thought to play a key role in the astrochemical evolution.  The so-called HACA mechanism–the hydrogen abstraction-acetylene addition mechanism–had so far only been speculated theoretically.  A news highlight from the Advanced Light Source user facility at the Lawrence Berkeley National Laboratory describes the research ...

With the global population expected to approach 9 billion by 2050 and climate change altering agricultural conditions, the world is “entering a perfect storm of challenges to global food security,” according to Thomas Lumpkin, an international expert in sustainable agricultural development who will speak in Honolulu on Monday, November 10. Lumpkin, the University of Hawai‘i at Mānoa’s 2014 College of ... Read More »

U.N. task force says new ocean telecom cables should be ‘green’

global undersea communications cable infrastructure

The global system of submarine telecommunications cables that supports our connected world is deaf, dumb and blind to the external ocean environment – and represents a major missed opportunity for tsunami warning and global climate monitoring, according to UH scientists and a United Nations task force. “For an additional 5-10 percent of the total cost of any new cable system ...

Massive debris pile reveals risk of huge tsunamis in Hawaii

1946 Hawaii tsunami

A mass of marine debris discovered in a giant sinkhole provides evidence that at least one mammoth tsunami, larger than any in Hawaiʻi’s recorded history, has struck the islands, and that a similar disaster could happen again, new research finds.  Scientists, led by Rhett Butler, Director of the Hawai‘i Institute of Geophysics and Planetology (HIGP) at UH Mānoa, are reporting ...

BOFFFFs [Big, Old, Fat, Fertile, Female Fish] sustain fisheries

Big Fish

Recreational fishermen prize large trophy fish.  Commercial fishing gear targets big fish.  After all, larger fish feed people’s egos as well as their bellies. A new compilation of research from around the world now shows that big, old, fat, fertile, female fish – known as BOFFFFs to scientists – are essential for ensuring that fishery stocks remain sustainable. “Information on ...
