EOI Scientists aboard the Schmidt Ocean Institute’s RV Falkor explored the Mariana back-arc spreading center (November 20 - December 17) and discovered four new hydrothermal vent sites. Researchers from NOAA and its cooperative institutes at the University of Washington and Oregon State University searched for these new hydrothermally active sites to gain a better understanding of the physical, chemical and geological forces that shape the biodiversity in these unique ecosystems. Scientists will return for a second cruise in the Fall of 2016 with a remotely operated vehicle to further characterize and sample the new vent sites.

A paper just published in Nature Geoscience shows a newly recognized role for hydrothermal vents in the global carbon cycle. This new research, by PMEL/JISAO researcher David Butterfield and colleagues, shows that hydrothermal vents may act as a recycling and decomposition system for dissolved organic carbon (DOC), an important constituent of the global carbon pool. The scientists... more
