In addition to drilling vessels such as the JOIDES RESOLUTION, a first generation of portable seafloor drilling and coring systems (Table 3) is available including the PROD (Portable Remotely Operated Drill), which was jointly developed and constructed by the US/Australian group of Benthic GeoTech Pty. Ltd., Williamson and Associates. Inc., and the University of Sydney. Performance specifications for PROD include a maximum penetration of 100 m at an operating depth of up to 2,000 m, and a rock core diameter of 40 mm with individual core lengths of 2.2 m. So far, however, the drill has not yet been fully tested and longer cores have not been retrieved. A second drill, the BMS (Benthic Multicoring System) was built by Williamson and Ass. Inc. for the Metal Mining Agency of Japan (MMAJ) in 1996 and is presently installed on the research vessel Hakurei Maru No. 2. The BMS uses conventional diamond rotary-rock and soil sampling tools and can be operated from ships-of-opportunity at water depths of up to 6,000 m. Individual cores have a diameter of 44 mm at a maximum coring depth of 20 m. The system has been successfully used by the MMAJ to drill in the submarine caldera of Suiyo Seamount at the Izu-Bonin Arc at a depth of 9.8 m achieving a core recovery of 26% 3 .
