Tree-ring δ18O and δ2H stable isotopes reflect the global meteoric water line

Original language description

Introduction The Global Meteoric Water Line (GMWL) describes the linear relationship between stable hydrogen (delta 2H) and oxygen (delta 18O) isotopes in precipitation over large spatial scales and therefore represents a unique reference for water isotopic values. Although trees have the potential to capture the isotopic composition of precipitation, it remains unclear if the GMWL can be reconstructed from tree-ring stable isotopes, since delta 18O and delta 2H undergo in vivo physiological fractionation.Methods We analyze the tree rings delta 18O and delta 2H values from six regions along a latitudinal gradient from Spain to Greenland.Results The data show that the covariance between delta 18O and delta 2H closely follows the GMWL, which reflects the isotopic signature of large-scale precipitation patterns. We show that changes in regional tree-ring delta 18O and delta 2H values along wide latitudinal ranges are influenced by the isotopic composition of precipitation with temperature and latitude being the most significant drivers of spatial variation across the studied regions. In contrast, local tree-ring delta 18O and delta 2H values are mainly controlled by plant physiological fractionation processes that mask the isotopic signature of precipitation.Conclusion We conclude that covariance in tree-ring delta 18O and delta 2H reflects the GMWL at larger spatial scales, but not when evaluating them at individual sites.
