The Effect of Winds on the Underwater Low Frequency Ambient Noise Recorded at a Location off the West Coast of the United States.

Abstract

It is well established that the interaction of wind and sea at their interface may result in the production of significant levels of noise, particularly in the frequency range of about one hundred to several thousand cycles per second, when the noise is measured directly under or very nearly under the windswept area. It is not so well known what relationships, if any, exist between ambient noise levels in the very low frequencies and storms or wind activity measured at great distances from the hydrophone. It has been the purpose of this study to: (1) determine if and to what degree such relationships might exist and how this contributes to the character and magnitude of the sea noise now under observation, and (2) evaluate the usefulness of employing the weather map plotting chart presentation of meteorological data in the above.
