This program, an international scientific research program for joint research under a Grant-in-Aid for Scientific Research, has been carried out as a part of an international research program "InterRidge" on mid-ocean ridges. InterRidge program aims to promote multi-lateral cooperative researches as well as to make an initial science plan for international joint research programs. A joint session "InterRidge" will be held in the 1994 Spring Joint Meeting of Earth and Planetary Sciences in Japan, where many talks related with this program will be presented. These talks show that this program has supported many young Japanese scientists to start on ridge-related researches.It was one of important results of this joint research that a Hakuhomaru Indian Ridges research cruise was carried out quite successfully owing to international cooperations under InterRidge program. The 72-day cruise, July to September 1993, was the first major cruise for Japanese university scientists to investigate … More mid-ocean ridges. Interdisciplinary researches were focused on the study area near the ridge triple junction ; such a concentrated multi-disciplinary seafloor survey was the first experiment on mid-ocean ridges. This program was crucial to the international planning activities for the cruise as well as joint researches on geophysical mapping and petrological studies.Seafloor magnetic structures near mid-ocean ridges were extensively studied through joint researches on board foreign research cruises by use of shipboard three-component magnetometers. Joint researches were carried out during 5 American cruises on the East Pacific Rise, 2 cruises (American and English) on the Mid-Atlantic Ridge, a French cruise on the Pacific-Antarctic Ridge.Owing to this program, Japanese scientists have join the planning activities of the InterRidge Program. These activities are presented in InterRidge Program Plan as well as Global Studies Workshop Report and Meso-scale Working Group's Report, which will be published in April 1994 by the InterRidge Office.

该方案是一个在科学研究补助金下进行联合研究的国际科学研究方案，是作为大洋中脊国际研究方案“InterRidge”的一部分开展的。InterRidge项目旨在促进多边合作研究，并为国际联合研究项目制定初步科学计划。1994年春季在日本举行的地球和行星科学联合会议上将举行一次联合会议“InterRidge”，届时将举行许多与该方案有关的会谈。这些会谈表明，该计划支持了许多年轻的日本科学家开始与山脊有关的研究，这是一个重要的成果，这是一个白母丸印度山脊研究巡航进行了相当成功，由于国际合作下的国际大洋中脊计划。1993年7月至9月为期72天的巡航是日本大学科学家进行调查的第一次大型巡航 ...更多信息 大洋中脊跨学科研究的重点是海脊三联点附近的研究区域;这种集中的多学科海底调查是在大洋中脊进行的第一次试验。这一方案对于国际规划活动以及地球物理测绘和岩石学研究的联合研究至关重要，通过在外国研究考察船上使用船上三分量磁力计进行的联合研究，广泛研究了大洋中脊附近的海底磁性结构。美国在东太平洋海隆的5次巡航、大西洋中脊的2次巡航（美国和英国）、法国在太平洋-南极海脊的巡航中进行了联合研究。由于该计划，日本科学家加入了InterRidge计划的规划活动。这些活动载于国际大洋中脊协会方案计划以及全球研究讲习班报告和中尺度工作组报告，这些报告将于1994年4月由国际大洋中脊协会办事处出版。少
