Title: Laboratory and field measurements of breaking-induced turbulence: Implications for ocean acoustics
Abstract: The entrainment of air by breaking surface waves, its breakup into bubbles, and their transport in the surface layers by breaking-induced turbulence and Langmuir circulations have important consequences for active and passive acoustical oceanography. Recent laboratory and field work related to these issues will be presented. The description of breaking-induced turbulence and air entrainment by just field experiments is very difficult and there are some advantages to separating the issues into those that must be addressed in the field and those that are better studied in the laboratory. For example, the statistics of breaking cannot be resolved by laboratory measurements, whereas the detailed structure of the turbulence is probably better studied in the laboratory. New results from airborne measurements of breaking statistics, and laboratory (and field) measurements of breaking-induced turbulence will be presented and their implications for upper ocean acoustics will be discussed. Similarities between breaking-induced turbulence and Langmuir circulations will be discussed. [Work supported by ONR and NSF.]
