Abstract
The spectral measurements of the attenuation coeffiicient of sea water and the absorption coefficient of suspended particles and of yellow substance were made with a spectrophotometer for the- sea waters sampled in Tokyo Bay. These parameters can be used to compute the expected spectral irradiance reflectance.
Some relationships between the optical properties of sea water and the concentration of dissolved organic carbon, the dry weight of suspended matter and chlorophyll-a concentration are presented. On the basis of these results, the possibility of modelling the relationship between optical and material properties is discussed.
