The Effect of Monomolecular Films on the Underlying Ambient-Noise Field

Abstract

A series of at-sea tests have unequivocally established that the presence of a monomolecular surface film results in a pronounced reduction of ambient noise beneath the film. This reduction was observed over a wide range of surface conditions associated with sea states 1 through 6. Possible mechanisms through which the film affects the underlying ambient-noise field are explored.
