海底地震仪的性能对比及在渤海试验中的应用
Performance comparison of ocean bottom seismometers and their application in the Bohai Sea
摘要
Abstract
In March 2010, the First Institute of Oceanography, State Oceanic Administration (SOA) has launched a deep seismic detection test in the Bohal Sea, using three types of 51 ocean bottom seismometers (OBSs) including SEDIS VI OBS, MicrOBS and I-7C OBS made in Germany, France and China, respectively. It was found through comparison that:OBS made in China is better than the other two OBSs in coupling technology, power consumption and data storage capacity;I-7C OBS and MicrOBS are very easy to operate and express high efficiency in the sea when setting parameters and charging; The hydrophone of MicrOBS is advancing and able to obtaln data of high definition and continuity;SEDIS VI OBS has the best data collected from vertical component seismograph among the three types of OBSs. Our paper has pointed out the development trend of OBS:miniaturization, being portable, low-power consumption, high capacity, long period, broad band, low cost, and easily retrieving. The performance indexes of the three types of OBSs mentioned above were described in detalls and compared. The process of deep seismic detection test, data processing methods and the results achieved are described briefly.关键词
