Optical Properties of the Water in Adjacent Regions of the Kuroshio

Abstract

Measurements of the irradiance and scalar irradiance were made using an underwater irradiance meter and an underwater scalar irradiance meter at Sagami Bay and the East China Sea, adjacent regions of the Kuroshio. From these data, we calculated the values of volume absorption function, reflectance function and diffuse attenuation functions for scalar irradiance and irradiance. It is considered that the value of a=0.042•`0.049 m-1 obtained from the upper layer in the East China Sea is that of the absorption coefficient at wave length 550 mit of the water, on which the Kuroshio has influences.
