Outline of Final Research Achievements

In this research, using the latest remote sensing technique, the technical development to monitor sediment volume (or SS) and the water flow distribution was performed. At first, in-situ spectral reflectance / water quality data set was acquired in Amami-Oshima to achieve this goal. The acquisition data set was applied to bio-optical model and chromaticity theory. As a result, the SS on the coral reef was estimated from the sea surface brightness. On the other hand, the program which makes water quality distribution maps every 1 hour automatically has been developed using geo-stationary satellite sensor "GOCI" data as a research technique of flow by remote sensing.
