摘　　要：介绍了由中国科学院地质与地球物理研究所自主研发的基于实时数据传输的宽频海底地震仪.其在继承了原有沉浮式OBS体积小、重量轻、宽频带等优点的基础上,具有接口灵活、时钟精准、监测数据可靠实传、系统健壮可自恢复、在线升级的特点.仪器可作为各种海底观测台网的子节点并可单独使用,为实现对海底地震监测、海啸预警等长期观测提供有力支持,从而达到对其进行长期评估和实时预警的目的.Broad frequency ocean bottom seismograph based on real-time data transport developed by Institute of geology and Geophysics,Chinese Academy of Sciences is introduced.On the basis of advantages of small size,light weight and broadband inherited from the original ups and downs OBS,it presently has the characteristics of flexible interface,accurate clock,reliable real-time date,online upgrade,robust and restorable system.So it can be used not only as a subsystem of different kinds of undersea surveillance network,but also arranged alone.Therefore,the instrument can provide strong support for real-time,long-time observations on undersea earthquake and tsunami monitoring to achieve long-term assessment and real-time early warning purpose.
