Abstract
his paper deals with an application of image measurement of flow field in coastal area. It has been tried to measure the distribution of chlorophyll pigment in ocean using spectral irradiance ratio in the research field of remort sensing. When its technique can be applied to coastal zone, it would be a tracer for image measurement of the current.
The photographs in Yura Bay, located in the southern part of Osaka Bay, are taken with several optical filters. The chlorophyll distribution is analyzed and conventional cross-correlation method is applied to measure the current. The result is compared with the path line of buoy.
