International Cooperative Research on the mid-Oceanic Ridges-Earth Environmental Dynamics and Mid-Oceanic Ridge

这一预算是日本对应的国际大洋中脊协会方案。预算用于日本科学家的旅费和研究航行仪器的运输、日本科学家参加国际大洋中脊协会会议的旅费以及应邀的外国科学家的旅费。洋中脊研究航行的成果该项目的日本科学家成员参加了在西太平洋、印度洋、北方大西洋和弧后盆地的12次研究航行。研究领域包括构造学、地球化学、地震学、岩石学、生物学和微生物学。主要成就包括在印度洋发现第一个活动喷口地点，查明印度洋亚丁裂谷系的热点-海脊相互作用。北极海中的波波维奇海岭的分段构造制图.该项目的日本科学家成员积极参加了国际大洋中脊协会组织的指导委员会、讲习班、专题讨论会和理论研究所。作为日本科学家为国际大洋中脊协会项目开展的活动，指导委员会批准从2000年起将国际大洋中脊协会办事处迁往日本，为期4年。该办公室现在设在海洋研究所，K。玉木担任主席。3.邀请国外科学家我们邀请了俄罗斯、英国、也门、法国等国的科学家，对考察航行进行总结讨论，并制定未来的计划。通过与受邀外国科学家的讨论，提出了关于大西洋洋中脊的两个新建议。

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.
