EOI Scientists aboard the Schmidt Ocean Institute’s RV Falkor are exploring the Mariana back-arc spreading center, which is expected to host to a number of volcanic vents teeming with life. Researchers from NOAA and its cooperative institutes at the University of Washington and Oregon State University are searching for 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 next year with a remotely operated vehicle to further characterize and sample the newfound 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
