Wave Induced Bubble Clouds and Their Effect on Radiance in the Upper Ocean

Abstract

A goal of this project is to measure wave induced bubble clouds and their effect on radiance in the upper ocean and to address the fact that despite the fundamental importance of optical backscatter in the ocean it is still not possible to explain more than 5 to 10 percent of the particulate backscattering in the ocean based on known constituents even during periods with no active wave breaking (Terrill & Lewis, 2004). We intend to investigate the role of upper ocean bubbles in these processes. In this work we are working closely with David Farmer at GSO/URI. The role of manmade and natural surfactants in upper ocean processes is presently also poorly understood. Therefore, a second goal of this project is to improve on our understanding of how these surfactants modify the bubble field, the surface wave field and ultimately the upper ocean radiance.
