AIRGUN ARRAYS
DEFINITION
- An airgun array is composed of multiple airgun units. An airgun is essentially a stainless steel cylinder charged with high-pressure air. The seismic signal is generated when that air is almost instantaneously released into the surrounding water column. The effect is similar to popping a balloon; a loud sound is created when the air inside the balloon is quickly expelled into the atmosphere. [Summary provided by IAGC]
