AbstractThe submarine cabled seafloor seismic station (network), a new type of observation platform for Earth Science research, is a new technology based on submarine optoelectronic composite cable, which extends the traditional onshore seismic station to offshore area, covers the shortage of the seismic station in offshore area, and realizes real-time and long-term continuous observation of earthquakes and earth's internal processes. It has become an innovative research platform for marine science presently and relevant technologies have also made great progress. In 2018, the Fujian offshore seismic station was developed and constructed in China. Based on the previous research, breakthrough progress has been made for the key technology of submarine cabled seismic observation such as underwater connection technique, etc. , and the real-time network access function was realized. It has the ability to enter the seismic industry network of China Earthquake Administration. The stability and reliability of the system have been verified by the real-time observation for more than three months. In this paper, the key technologies and construction processes, key technical links, relevant specifications and test results of the research and development of the submarine seismic station (network) in Wuyu Island, Fujian Province are introduced in detail. The earthquake data acquisition show that the data flow service is realized and the connection with CEA's JOPENS system is stable. Real-time data transmission is normal and real-time waveform data is automatically stored. During the period of trial operation, the operation rate is more than 99% and it has reached the excellent standard stipulated by the national seismological network management. The results of research and development can provide important reference index and experience for the construction of Chinese submarine cabled Seismic Observatory (network) in the future.
