The A. B. Wood laboratory, at the Institute of Sound and Vibration Research, contains one large and several small tanks of fresh water. The large tank measures 8 m × 8 m × 5 m deep. This tank has a bubble generation system which generates bubble populations with a bubble size distribution and number resembling that found under breaking ocean waves. Several small tanks provide a range of water and saturated sediment environments. A suite of acoustic sources and sensors and underwater video cameras are available.
