摘要
The influence of the optical properties of inorganic suspended solids (ISS) on in-water algorithms was evaluated using an optical model in highly turbid coastal water, whose ISS concentration reached several hundred grams per cubic metre. The measurements were conducted in the upper Gulf of Thailand. The backscattering coefficient of the ISS was calculated using the Lorenz-Mie scattering theory. On the basis of the measurement, the ISS size distribution was parameterised as a function of ISS concentration, and both the spherical and non-spherical particle shape models were evaluated. For ISS concentrations of 10 g m(-3), an estimate of the chlorophyll-a (Chl-a) concentration within a factor of two on a logarithmic scale is possible in a Chl-a range of 4-30 mg m(-3).
