Abstract

 Off the east coast of Japan mainland is called as the mixed water region formed by various water masses, such as the Kuroshio Water(KW), Oyashio Water(OW), and Tsugaru Warm Current(TWC). The mixed water region is known to largely influence marine environments and ecosystems in the North Pacific Ocean. This study investigated seasonal variations of water masses off the east coast of Japan mainland using the Regional Ocean Modeling System (ROMS). We developed a water mass classification method based on the standardized TS-diagram. The newly developed method allowed us to detect water masses in surface layers and coastal oceans, which are not simply detected by a conventional TS analysis. The seasonal variation of TWC influences the distribution and southern boundary of OW. TWC and KW are mixed off Kashima-nada accompanied by eddies in winter and spring season.
