Abstract

A phenomenological model of the beam spread function is fitted to Duntley's measurements in artificial seawater in the turbidity range 0.60 less than or equal to s/α less than or equal to 0.83 which is constructed by first delineating the angle-dependence of the curves of the irradiance distribution for given radial distance and then obtaining the radial dependence of their scaling by normalizing to the total spherical-cap integral. The paraseters of the sodel are all easily identified graphically and therefore lend themselves readily to physical interpretation. The agreesent of the sodel with the data is excellent, and it is expected that it should extrapolate well not only to all distances and angles but also to values of the turbidity s/u well outside of the range of the data, including the high-turbidity halt 0.9 s/α 1.
