Steven J. DeRose,David G. Durand-floor surveys, three field programs focused on Northern Gorda Ridge, using state-of-the-art shipboard and in situ determinations of physical, optical, and chemical properties useful in “prospecting” for active venting. The results of these investigations demonstrate the presence of active venting i

The Value and Cost of a Vital Resource deposition occurred over changing regimens of temperature and fluid chemistry. Oxygen isotope analyses and secondary mineral phases indicate that metagabbros formed at temperatures in excess of 500°C. Basalt and diabase breccias formed at temperatures between 350°C and 500°C.

Making Innovation Last: Volume 2 distribution of benthic fauna at two study areas in Escanaba Trough at the southern end of Gorda Ridge. Five dives examined three seafloor hills that had been surveyed and sampled during previous surface ship programs, including one at latitude 41° N, longitude 127° 30′ W (the NESCA site), and two

Vent fluids typically undergo a 10.-fold dilution as they rise several hundred meters above the sea floor and form neutrally buoyant plumes with heat and chemical anomalies that stretch tens to thousands of kilometers downcurrent of their source. Real-time mapping of these
