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 »

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 ...

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 ...
