Climatic and atmospheric influences on carbon isotope ratios stored in tree rings Fuglem, Naomi; Nelson, Kristina

Abstract

The б¹³C values of 30 individual tree rings from a Douglas Fir (Pseudotsuga menziesii ) were analyzed. These data were compared with local climatic data, total tree ring size and late- wood/earlywood ratio to determine the degree of correlation. The results provide indication of correlation between different aspects of tree growth and precipitation. A yellow cedar (Callitropsis nootkatensis ) was also analyzed in ten year increments for long-term б¹³C trends, which may be representative of atmospheric б¹³C trends.
