The possibility of the long range propagation of sound waves in the sea near the Okinawa Islands depends on whether or not of the existence of a sound channel. The character of the sound channel in the Western North Pacific, including the above mentioned regions, was investigated by use of the observation data of temperature and salinity by the Japanese Hydrographic Office during 1936 and 1946. The results are as follows: a) There was no sound channel in the East China Sea or the Yellow sea, but the formation of a sound shadow zone was perceptible. b) The sound channel in the Western North Pacific appears to be closely related to the Kuroshio. Especially, it is evident that the character of the sound channel in the sea southwest of Japan is greatly influenced by cold water masses, which arise frequently off Shiono-misaki, and which bear directly on the variability of the flow pattern of the Kuroshio.
