Abstract

The action of wind stress upon the marine surface is responsible for producing air bubbles in seawater through wave breaking. After a given residence time in the sea, bubbles return to the surface, where they burst. The phenomenon of bursting produces two families of droplets: film drops and jet drops. The characteristics of jet drops are far better known than those of film drops. By means of an in‐line holographic technique one can obtain experimental results through visualization. One can observe the successive stages of the bursting process of a single bubble in deionized fresh water and in seawater. One visualizes both film drops and jet drops generated by bubbles whose diameter may attain 10 mm. The onset of the bursting phenomenon is clearly shown. Film drop count and size are measurable and may be compared with other available estimates.
