The dendroclimatic value of oak stable isotopes
Original language description
Tree-ring stable oxygen and carbon isotope ratios (818O and 813C) are an important archive for climate reconstructions. However, it remains unclear whether the polyvinyl acetate emulsion, often used for the preservation and fixation of wood samples, influences 818O and 813C signals. Further uncertainties are associated with the possible effects of geographical origin and cambial age of historical samples. Here, we present annuallyresolved and absolutely-dated 818O and 813C measurements of 21 living oaks (Quercus robur and Q. petraea) from the Czech Republic. We find that the 818O and 813C signals in the extracted alpha-cellulose are not affected by polyvinyl acetate treatment. Covering the entire 20th century and reaching until 2018 CE, our dataset reveals spatial and temporal coherency within and between the individual 818O and 813C chronologies of different oak species, sample locations, and tree ages. Highly significant (p < 0.01) Pearson's correlation coefficients of the site-specific 813C and 818O chronologies range from 0.48-0.77 and 0.36-0.56, respectively. The isotopic interseries correlations of Q. robur and Q. petraea from the same site are 0.75 and 0.43 for the mean 813C and 818O values, respectively. Significant (p < 0.01) correlations of 0.49 and 0.84 are found for 813C and 818O, respectively, when all measurements from all sampling locations and tree ages are included. Our study shows that nonpooled oak 818O and 813C measurements from both species, different locations, and diverse tree ages can be combined into robust isotopic chronologies for climate reconstructions.
