We have investigated potential of long-lived cold water bivalve, Mercenaria stimpsoni (Stimpson\u0027s hard clam) living in Funakoshi Bay located in North East Japan. In this paper, we show some preliminary results of sclerochlonological and geochemical approaches (e.g., oxygen isotopes) on both live-caught and dead specimens by which we attempt to establish master-chronology and to reconstruct past environmental changes for the last 150 years in the western North Pacific (e.g., water temperature, nuclear bomb-14C
