By taking together various observations on air bubbles bursting at the surface of seawater, the production rate and size spectrum of film drops are deduced. The number of film drops produced is proportional to the square of bubble diameter, and the size spectrum of film drops produced by bubbles of various diameters is universal. These are consistent with the concept that the numerical production of film drops is related physically to the surface area of the bubble film cap. The size spectrum of film drops can be described by a two-segment power law: d-1/2 and d-2 divided at the droplet diameter d=90 μm. Many film drops were observed having diameters much greater than the previously suggested diameters, 4--15 μm, separating the dominant contribution of film and jet drops. ¿ American Geophysical Union 1994
