Seismic control system

The seismic survey system utilizes high-pressure air (2000 psi) released through an air gun to generate an explosive acoustic source. The resulting reflected and refracted sound waves, caused by differences in acoustic impedance between layers beneath the seafloor, are received via hydrophone cables. By analyzing the travel time of these sound waves, subsurface structures below the seafloor can be interpreted. Since the sound waves generated by high-pressure air guns are of relatively low frequency (below 50 Hz), they possess high penetration capability (over 1 kilometer), making them highly effective for deep stratigraphic exploration. This system is an essential tool in both plate tectonics research and industrial petroleum exploration.
