| Definition | A marine seismic energy source divided into two chambers, the firing chamber, which contains compressed air, and the other chamber, which is filled with water. When the gun is fired, the compressed air forces the shuttle downward and this expels the water from the lower chamber. The shot of water leaving the gun creates a void behind it and the collapse of water into this void creates an acoustic wave. | ||
