Near surface wave-turbulence via a shadowgraph technique
Abstract
A standard shadowgraph system is used to study the mechanisms of near surface wave-turbulence. Warm water is mixed with the underlying cold water by drift currents and waves. The resulting shadowgraphs are recorded with photographic and video equipment. Filtering, ie, enhancing and edge detection, is performed on the shadowgraphs via an image processing system in order to provide detailed information on the wave-turbulence structure of the aqueous upper layer.
