Abstract : Ambient noise data were collected with two vertical arrays during a surface breaking wave experiment conducted 22 March-5 April 1995, North East of San Clemente Island. Conventional beamforming is applied to the data and the beamformed outputs reveal signatures of acoustic sources moving across the sea surface. Simultaneous video observations confirm that the detected acoustic sources are indeed associated with breaking surface waves. Further efforts are needed to develop an event identifications scheme for systematic analysis of the data.
