Abstract: Light transmission in natural waters is a complex radiative transfer process and leads to a set of inverse problems, in order to estimate the different properties involved in this process. Our study includes the identification of bioluminecence source profiles, estimation of absortion and scattering coefficients, a simultaneous reconstruction of all properties cited before, and, recently, reconstructions of the phase function and boundary conditions. All estimations were done using noise-corrupted synthetic data, corresponding to "in situ" experimental data. As new perspective, the use of remote sensing data is an important issue in this topic. Algorithms for performing inversions from remote sensing data are outlined.
