Paper Abstract

An inverse problem of ocean optics is solved for estimating the scalar irradiance and a source, such as fluorescence, bioluminescence, or Raman scattering, or an optical property such as the absorption coefficient. The solution requires in situ measurements of the downward and upward irradiances and a priori estimation of the angular shape of the volume scattering function. The iterative inversion procedure is developed from asymptotic two-stream radiative transfer equations and the conjugate gradient method. Preliminary numerical tests show that the algorithm is quite accurate in the region away from the surface but gives appreciable errors close to the surface where the asymptotic two-stream equations are a poor approximation.
