air gun: A chamber filled with compressed air, often used offshore in seismic exploration. As the gun is trailed behind, air is released, making a low-frequency popping noise, which penetrates the subsurface rock layers and is reflected by the layers. Sensitive hydrophones receive the reflections and transmit them to recording equipment on the boat.  3, record 1, English, - air%20gun%20barge
