Effect of Monomolecular Films on the Underlying Ocean Ambient Noise Field at Low Sea States

Abstract

In sea states two-six, monomolecular films on the ocean surface have been previously reported to dramatically reduce the ambient noise field beneath them. The mechanism was presumed to be associated with ocean whitecapping. A recent series of low sea state tests with films, in the absence of whitecapping, has found an even more pronounced ambient noise reduction if the ocean surface agitation is above a certain critical level. The mechanism through which the films reduce surface noise at low sea states is explored. Multimedia reprint. (RRH)
