Outline of Final Research Achievements

The main objective of this research was to develop methodology to drastically improve efficiency of tree-ring isotope analysis. We initially attempted to develop a machine that analyses tree-ring isotope at high resolution. This turned out to be difficult due to technical problems. We then tackled other technical problems that hinder efficient tree-ring isotope analysis, such as (1) core sampling method and (2) chemical pretreatment before isotope analysis. We developed automatic core sampling system and developed cellulose extraction method that enables extraction of cellulose from whole tree-ring lath, which improved the labor efficiency of the chemical pretreatment by 10 to 100 times.
