The Ocean Bottom Seismometer (OBS) is a seismic observation device that places detector on the seabed and can record P and S waves generated by earthquakes. It can be used both for natural seismic (passive source) observations and for artificial earthquakes (active Source) in ocean exploration. In recent years, OBS has developed rapidly in the exploration of the seabed. Many countries have developed and applied it to seismic exploration and achieved some favorable results. The structure and working principle of OBS produced in various countries are roughly the same, and the domestically developed OBS also reach the advanced level in the world. Active OBS data processing flow mainly includes: data format conversion, secondary positioning, time difference correction, datum correction,horizontal(X,Y)component rotation,wave field separation, gain recovery, filtering, deconvolution, P wave, PS wave velocity analysis, migration imaging, etc. The technology is widely used in natural gas hydrates, oil and gas resources exploration and marine engineering and deep seabed structure surveys. Through the combination of P and S-wave inversion, the relationship between velocity anomaly and hydrate, free gas, or hydrocarbon bearing formations can be identified to better define the scope of reservoirs. Scholte waves are used to image sea bottom sediments in marine engineering surveys and evaluated by imaging results to reduce damage caused by underwater activities during construction. In the survey of the deep structure of the seafloor, OBS has been widely used in the sea areas of the South China Sea, Bohai Sea and the Yellow Sea. This method can provides better data for deep crustal and mantle velocity structure analysis, submarine tectonic activity and basin evolution, make up for the shortcomings of the previous methods, and laid the foundation for the later geological geophysical interpretation. With the development of instruments and advances in data processing technology, OBS will play a greater role in future geophysical exploration.
