Paper Abstract

In order to obtain more information on the angular scattering behavior of algae and silt research was initiated to determine whether or not the volume scattering functions by Petzold of the San Diego Harbor are appropriate for use in other types of turbid waters as is often stated in literature. This paper presents a selection of the measured angular scattering distribution functions over the range 10 degrees-165 degrees, the extrapolated angular scattering distribution functions extended to the range of 0 degrees- 180 degree by fitting Mie functions and the calculated backward scattering to total scattering ratios. The San Diego Harbor measurements by Petzold may not be applied to other turbid waters; it is in the backscattering region where the samples deviate most from the San Diego ASD from Petzold. A large addition to existing literature values for backscatter probabilities is presented for 14 freshwater and marine algal species samples and 2 estuarine silt samples.
