摘要

在海洋地区进行高质量的长期地震观测是全球地震观测的一个重要组成部分，DSDP／ODP是唯一能够钻穿软的沉积物、在坚硬的岩石里安置地震传感器这一目标的科学计划。介绍了ODP航次在井孔中设立地震台站、并获得一些有趣的结果的成功例子。ODP在日本外海布置了两个井中地震台站，与陆上台站一起来观测板块边界的活动性。此外，还介绍了西太平洋井中宽带台站、海上地震信号和噪音等问题。

Abstract

To establish long-term high quality seismic stations is an important part of the global seismic observation. DSDP/ODP provide to be the only scientific program that could enable such an operation as to penetrate the soft sediments and to install the seismic stations in the hard rock. This article presents examples of how ODP Legs succeeded in establishing such borehole stations and obtained some interesting results. In order to observe plate boundary seismicity, two borehole stations were installed offshore Northern Japan with broadband seismometers, in combination with land stations. Topics such as broadband borehole stations in the Western Pacific and marine seismic signals and noises are also discussed. 

Key words： Ocean drilling; Seismic stations; Marine;Seismology.
