This budget is the Japanese counterpart of the InterRidge program. The budget is used for travels of the Japanese scientists and transportation of the instruments for research cruises, travels of the Japanese scientists to participate InterRidge meetings, and travels for invited foreign scientists.1. Results of mid-oceanic ridge research cruisesThe Japanese scientist members of this project participated 12 research cruises in the Western Pacific, Indian Ocean, Northern Atlantic, and the back-arc basins. The research fields cover tectonics, geochemistry, seismology, petrology, biology and microbiology. Major achievements are the discover of the first active vent site in the Indian Ocean, identification of hotspot-ridge interaction at the Aden rift system in the Indian Ocean., and mapping of segment configuration of the Knipovich Ridge in the Arctic Sea.2. Promotion of InterRidge programThe Japanese scientist members of this project intensively participated steering committees, workshops, symposiums, and theoretical institutes organized by InterRidge. As the activity of the Japanese scientists for InterRidge project, the steering committee approved to move the InterRidge Office to Japan for 4 years from 2000. The Office is now at the Ocean Research Institute, and K. Tamaki serves as a chairman.3. Invitation of foreign scientistsWe invited a number of scientists from Russia, England, Yemen, and France to do the summary discussion of the research cruises and to devise future program plan. Two new proposals for the mid-oceanic ridge of the Atlantic ocean were submitted through the discussion with the invited foreign scientists.
