  skos: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.
