Multichannel Reflection Seismic System

A seismic system utilizes high-pressure air (2000 psi) released through air guns to generate explosive acoustic sources. These sound waves travel through the seafloor and underlying layers, where differences in acoustic impedance cause reflections and refractions. The returning signals are captured by hydrophone streamers, allowing researchers to determine subsurface structures based on the travel time of the waves. Since the sound waves produced by high-pressure air guns are of relatively low frequency (below 50 Hz), they possess strong penetration capabilities—often exceeding one kilometer. This makes the system highly effective for investigating deep geological formations. It is an essential tool for both plate tectonics research and industrial petroleum exploration.
