Abstract
Satellite remote sensing methods of ocean color was developed based on the results of field observations in an eutrophication water area, Tokyo bay. From field observations, it was found that absorption coefficients of phytoplankton and detritus were related to Chl-a and that of color dissolved organic matter (CDOM) to salinity. On the basis of these optical properties, bio-optical model was developed and it showed that aph spectrum around 550nm increased when red tides occurred by the developed model. In addition, using these findings, we developed three parameters, Chl-a estimation model which assimilates observation results, aCDOM estimation model which uses two bands, blue region and red region and ad estimation model, modification of the Quasi-Analytical Algorithm. Furthermore temperature estimation accuracy by MODIS sensor was validated. Thus, it became possible to estimate each of four parameters spatially and simultaneously.
