Abstract: Slug dye diffusion study to obtain the horizontal diffusivity was often carried out in Japan in 1960s to 1970s. The data of these studies are reviewed. Also, several methods to obtain the oceanic diffusivity are reviewed. Especially, a new method generalizing the method pro- posed by Gifford for analyzing the atmospheric diffusion, is proposed and shown to be quite effective if the maximum dye cloud area is known. The overall characteristic of horizontal diffusivity in the coastal sea is reviewed.
