一种向水中射入一个高压空气泡的震源

Air gun. (a) High-pressure air flows continuously into the upper chamber and through the shuttle into the lower chamber. Opening the solenoid valve puts high-pressure air under the shuttle seat causing the shuttle to move upward, opening the lower chamber and allowing its air to flow out through ports to form a bubble of high-pressure air in the water. The size of a gun is the size of its lower chamber. (Courtesy Bolt Associates.)
(b) Sleeve gun; the sleeve around the gun slides back to release the air into the water.

。当气泡交替地膨胀和收缩时震动而产生一个声波,它地频率取决于气泡中空气总量,压力和水深。有时使用不同大小气枪地组合一产生更宽的频谱frequency spectrum。空气枪也可以放入钻孔中或沼泽里,但不适合在泥或沙中,以免它们进入和污染空气枪。空气枪也可以放在一个水箱里置于地面上作为陆上震源。[1]<ref>Caldwell, K. and Dragoset, W., 2000, A brief overview of seismic air-gun arrays: The Leading Edge, 19, 898–902. http://dx.doi.org/10.1190/1.1438744</refs>
