Research Abstract

The behavior of low salinity water from the East China Sea originated from the continental river discharge was investigated. Salinity measurements in the surface layer with T-S meters attached with fisheries trap-nets revealed that the low salinity water is transported from the Tsushima Strait to the Tsugaru Strait at about 0.3 ms^<-1> within two months. The comparison of the 30-year long salinity data in the Tsushima Strait with that of the northwest off the Noto Peninsula revealed that the low salinity water from the eastern channel of the Tsushima Strait varies the surface salinity around the Noto Peninsula with a month time lag.
