项目摘要

The spreading ridges are now recognized as an extensive province of focused mass and energy exchange that affects the entire earth. Technological progress has provided strong support for the scientific impulse to pursue investigations of the ridges. The objective of this program is to initiate cooperative researches of the geodynamics of crustal accretion in the mid-ocean ridges and back-arc basins as a joint research program among Japan and US/European countries.Although this program was approved as a one-year preliminary program, it has produced a good chance to initiate cooperative researches, and to join the international planning activities for the InterRidge program.A RIDGE workshop on observation of temporal variability of ridgecrest processes was held in November 1991 in Seattle. Dr. Kanazawa attended the workshop and discussed on future research programs and instrumental developments. Drs. T. Fujii and T. Gamo attended RIDGE Theoretical Institute held in January 1992 in Tucson, Arizona, and discussed on the observed results and theories of hydrothermal and magma chamber processes at mid-ocean ridges and back-arc basins.The Mariana Trough and Ayu Trough in the western Pacific were surveyed by several members of the research group of this program during the Hakuho-maru cruise KH-92-1. Dr. Laura Kong, NOAA in Hawaii, was invited to the Mariana Trough cruise and joined in the bathymetric and seismic survey of the ridge segmentation.The InterRidge program has been pursued as an international and interdisciplinary research initiative concerned with all aspects of midocean ridges, and is going to start at the 2nd InterRidge meeting held in March 1992 in York, UK. Drs. Tamaki and Fujimoto will attend the meeting to make a program plan. Owing to the one-year research activities under this joint program, the research group has made a ground for future integrated research programs of spreading ridges.

现在，扩散的山脊被认为是影响整个地球的广泛集中的质量和能量交流省。技术进步为科学冲动提供了强烈的支持，以追求对山脊的调查。该计划的目的是启动对中山山脊和后弧盆地中地层积聚地球动力学的合作研究，作为日本和美国/欧洲国家之间的联合研究计划。尽管该计划已被批准为一年的初步计划，但它既有机会启动临时的研究计划，又可以在国际上进行合作计划。 Ridgecrest流程于1991年11月在西雅图举行。 Kanazawa博士参加了研讨会，并讨论了未来的研究计划和工具发展。博士。 T. Fujii和T. Gamo参加了1992年1月在亚利桑那州图森举行的Ridge理论研究所，并讨论了在西部太平洋地区的Mariana Frough and Ayu Frough在西部太平洋地区进行了研究的结果和后山山脊和后山脉盆地中观察到的结果和理论。 KH-92-1。夏威夷NOAA的Laura Kong博士被邀请参加Mariana Trough Cruise，并加入了Ridge细分的测深和地震调查。Interdide计划已被作为一项国际和跨学科的研究计划，与Midecean Ridges的各个方面有关，并将在2nd Interidge举行，并将在1992年3月在1992年在1992年举行。博士。 Tamaki和Fujimoto将参加会议制定计划计划。由于该联合计划的一年研究活动，研究小组为将来的综合研究计划奠定了基础。
