Light scattering coefficient of seawater for arbitrary concentrations of hydrosols

The scattering coefficient of seawater as a function of concentration of hydrosol particles is calculated. The approach used is based on the Maxwell´s equations in a stochastically scattering seawater. The water is modeled as a thermally fluctuating medium filled with the hydrosol particles. It is found that the scattering coefficient quadratically depends on concentration when the concentration of scatterers is very small. The scattering coefficient is linear to concentration of scatterers at values typical to the open ocean. At the values of concentrations typical to coastal waters the dependence on concentration weakens and reaches the saturation at very high values
