Abstract:

The objective is to produce high quality, moving colour images of objects in the ocean and on the sea floor, using ambient noise from wind-driven and biological sources as the only source of acoustic illumination. Imaging breaking surface waves from below is also an important objective, with a view to establishing the acoustical properties of bubble clouds as they evolve in time, frequency and space. The imaging technique is covert, with the potential for imaging partially buried and proud mines in shallow water, up to and including the surf zone. Other possible applications include harbour entrance monitoring, moored-ship defence, and structural-integrity diagnosis of off-shore platforms.
