Abstract: Hydrographic measurements by CTD were made in the western-central Equatorial Pacific (160°W-147°E) during the Japanese Pacific Climate Study cruise in January-February 1991. In T-Sdiagram, three water masses are seen in the layer of sq= 25.0-26.5 kg/m3: salinity water corresponding to the Tropical Water of eastern South Pacific origin, less saline water in the North Pacific, and water with salinity between the above two, found on the equator. In three meridional sections (160°W-160°E), the Tropical Water of eastern South Pacific origin extends further equatorward than the climatological data of Levitus (1982).
