Popular version of paper 2pAO7 Presented Tuesday afternoon, December 2,1997 134th ASA Meeting, San Diego, CA Embargoed until December 2 1997 Ambient Noise Imaging (ANI) is a new concept in seeing underwater with sound, quite different from active and passive systems which have existed in biological contexts for perhaps millions of years, and in workable man-made versions for less than a century. Active systems rely on hearing the echoes from sound injected into the environment. Dolphin and bat echolocation are biological examples, while the classic ‘ASDIC’ anti-submarine warfare system o
