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.

该项目是科学研究资助项目下的国际联合科研项目，是大洋中脊国际研究项目“InterRidge”的一部分。InterRidge计划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。“InterRidge”联合会议将于1994年在日本举行的地球和行星科学春季联合会议上举行，届时将举行许多与该计划有关的会谈。这些谈话表明，该计划支持了许多年轻的日本科学家开始与山脊相关的研究。这次联合研究的重要成果之一是，由于InterRidge计划下的国际合作，白本丸印度洋脊研究巡航非常成功。从1993年7月到9月的72天的航行，是日本大学科学家第一次调查更多洋中脊的主要航行。跨学科的研究主要集中在山脊三线交界处附近的研究区域；如此集中的多学科海底调查是首次在大洋中脊进行的实验。这一项目对邮轮的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。利用船载三分量磁力计对洋中脊附近的海底磁结构进行了广泛的研究。在东太平洋隆起的5次美国巡航，在大西洋中脊的2次巡航（美国和英国），在太平洋-南极脊的一次法国巡航中进行了联合研究。由于这个计划，日本科学家加入了InterRidge计划的规划活动。这些活动载于InterRidge方案计划以及InterRidge办事处将于1994年4月出版的全球研究讲习班报告和中尺度工作组报告。少
