Monitoring Air-sea Exchange Processes Using the Ambient Sound Field

Abstract

The ambient sound field in the ocean contains information about processes producing the sound. At higher frequencies, above 1 kHz, much of the sound is produced locally by air-sea exchange processes such as wave breaking, wind and precipitation. Furthermore, ambient bubble populations can modify these sound fields in predictable ways. By learning to listen to the ambient sound field, we will be able to develop a method for measuring these phenomena using inexpensive and robust sensors (passive hydrophones).
