[VIDEO] Coral reef experts bridge science to public policy

ICRS video screen capture

Experts say the world’s coral reefs are in severe decline. Coral bleaching reached historic levels over the last several years. This important ecological, economical and cultural resource is at risk. That is why about 2,500 delegates including three Pacific heads of state met in Hawaiʻi in June for the 13thInternational Coral Reef Symposium. The meeting’s convener, the University of Hawaiʻi ...

An array of GPS instruments near the San Andreas Fault System in Southern California detects constant motion of Earth’s crust—sometimes large, sudden motion during an earthquake and often subtle, creeping motion. By carefully analyzing the data recorded by the EarthScope Plate Boundary Observatory’s GPS array researchers from the University of Hawaiʻi at Mānoa, University of Washington and Scripps Institution of ...

[VIDEO] UH playing important role in NASA coral study


The University of Hawaiʻi at Mānoa’s Hawaiʻi Institute of Marine Biology is playing a significant role in NASA’s Coral Reef Airborne Laboratory, a 15-million dollar three-year field study of Earth’s coral reef ecosystems announced in June 2016. A sophisticated new NASA airborne instrument called PRISM will fly at 28,000 feet and survey reefs at multiple locations from Hawaiʻi to Australia. ...

NSF funds undergraduate DNA and biodiversity research

REU undergraduates

The University of Hawaiʻi at Mānoa has received a Research Experiences for Undergraduates (REU) Site award from the National Science Foundation (NSF). Through this award, undergraduates will use high-throughput DNA sequencing, phylogenetic methods and bioinformatics to study microbiomes and the identities and origins of Hawaiʻi’s endemic, native and introduced organisms. Mentorship will be provided by faculty from the UH Mānoa ...

New research published in Scientific Reports by scientists at the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology suggests that ingestion of the toxic dinoflagellate Alexandrium fundyense changes the energy balance and reproductive potential of a particular copepod, a small crustacean, in the North Atlantic that is key food source for young fishes, including many commercially important species. Alexandrium fundyense is a photosynthetic ...

Corals and humans share genes


University of Hawaiʻi at Mānoa scientists at the John A. Burns School of Medicine and the Hawaiʻi Institute of Marine Biology (HIMB) have published new research showing that corals share many of the genes humans possess, especially those that can sense temperature and acidity, both of which are important to keeping both coral and humans healthy. The findings, published in the journal eLife, are the ...
