The present study established nuclear bomb testing induced bomb-14C records from M. stimpsoni shells, for the first time in high latitude western North Pacific, in which chronology is robustly constrained from a synchronized annual growth width pattern among individuals. The record revealed a strong influence of Tsugaru Warm Current on shallow water of northeast Japan. Furthermore, age-determination of dead shells collected from the seafloor of the study region by utilizing the established bomb-14C records suggests that past tsunamis are one of the most important reasons of death of M. stimpsoni.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"東北日本（岩手県大槌）から見つかった二枚貝の一種ビノスガイ（Mercenaria
