The Wakayama Research Center of Agriculture, Forestry and Fisheries(WRCAFF) keeps routine observation lines to the south of the Kii Peninsula(observation points are shown with dots in the upper figure of Fig.6. They observed high salinity water exceeding 35. 0 psu only once(August 2, 1984) in their observation history starting form 1963. Wbanalyzed all data the region which have been archived by JODC for the period form 1975 to 1996(the data of WRCAFF had not archived in JODC database at the time of this analysis of Morikawa et al.,1997), and found 12 observation points where the salinity value higher than 35.0 were observed. Eapecially, R/V Soyo-maru of the Tokai regional Fisheries Research Laboratory, JFA observed such high salinity water at 4 stations on August1-2, 1984. So, we oonclude that such high salinity value is real one though its occurrence frequency is very low.
