| Outline of Final Research Achievements |
In order to examine the cause of the difference in radioactive carbon concentration of Japanese trees from the other northern hemisphere areas, we have designed 1) collecting the current living tree specimens of the three North Pacific Ocean, 2) dating by dendrochronology, 3) chemical treatment for measuring radiocarbon concentration, 4) measurement by AMS and 5) climate response analysis of time series data. During the subsidy period, we done 1) to 3), but due to the change to the research institute without the AMS in the second year, it was not possible to carry out after 4). However, acquisition of basic data for analysis and establishment of research collaboration system to achieve the purpose were able to be satisfactorily accomplished.
