Outline of Final Research Achievements

Sequential radiocarbon dating of Japanese tree ring which age was determined by dendrochronology and oxygen isotope ratio of cellulose was carried out identity the atmospheric 14C anomalies of Japanese archipelago. Comparing to IntCal13, little anomalies were found during 10c to 12c and 15c. On the other hand, turbulence was observed after 17c. These behavior coincide with wood members of early-modern building which agree well with SHCal13 rather than when applying 14C wiggle-matching method. However, anomaly observed in the latter of 17c does not coincide with previous study. Suess effect should be concerned after 18c.
