摘　　要：为填补我国海洋地震监测和海洋地震研究的空白,获得对海洋地震多发区域的监测能力,特此进行宽频带海底地震仪的研制.本文详细介绍了宽频带海底地震仪的设计目标、基本工作原理、组成结构及性能技术指标和研制过程.此外,还介绍了宽频带海底地震仪在中国南海东北部海域应用实例的实验结果,展示了宽频带海底地震仪在3000m海底所记录到的数据资料.In order to comprehensively improve marine seismic study and monitoring capability,ocean bottom seismograph （OBS） was developed. This paper describes the basic working principle of OBS,proposes its performance specifications. The overall design,composition and structure principle of the various components of developed broadband OBS are described in detail. This paper also introduces application example in the South China Sea,and shows the seismic waveforms from earthquakes recorded by the broadband OBS on the sea floor at 3000 m depth.
