"By focusing on technological solutions to meet specific needs, an ROV that is readily accessible to the deep-ocean scientific community was developed." temperature, host-rock composition, fluid chemistry and sulfide mineralization. Acknowledgments This work was funded by the Natural Environment Re- search Council, U.K., (grant numbers NE/F017758/1 and NE/I01442X/1) and is part of two larger biological and geological studies led by Dr. Jon Copley of the University of Southampton and Dr. Bramley Murton of the National Oceanography Centre, respectively. The Mid-Cayman Spreading Center vent fields were dis- covered in 2010 during cruise JC44, led by Dr. Douglas Connelly of the National Oceanography Centre. The HyBIS ROV is a joint development between Jo Gar- rard of Hydro-Lek Ltd. and Bramley Murton. The Eh sensor for this expedition was supplied courtesy of Professor Koichi Nakamura from Japan's National Insti- tute of Advanced Industrial Science and Technology.

With more than 20 years in deep-ocean research, he is an expert on the processes of formation and evolution of the oceanic crust, hy- drothermal systems and seafloor mas- sive sulfide deposits. With Jo Garrad, he originated and developed the HyBIS concept, and led its exploration of the Cayman Trough. Veit Hünerbach is a geologist and tech- nologist at the National Oceanography Centre, Southampton, England. His expertise is in acoustic mapping of the deep seafloor, and the development and installation of seabed observatories for long-term monitoring. He operated and piloted the HyBIS ROV during its explo- ration of the Cayman Trough. Jo Garrard is a design engineer at Hydro- Lek Ltd., a U.K.-based engineering com- pany specializing in underwater robotic systems. He was the lead mechanical engineer during the design process for the HyBIS ROV. 20 st / SEPTEMBER 2012 www.sea-technology.com
