Significant relationship between the backward scattering coefficient of sea water and the scatterance at 120 degrees.
Computations of Mie scattering by marine particles indicate that the ratios between the backward scattering coefficient and the scatterance at 120 degrees are ~6.9 +/- 0.4, 7.2 +/- 0.6, and 7.1 +/- 0.5 for Junge, normal and log-normal particle size distributions, respectively. In situ observations of the scattering confirm this result.
