Stable oxygen isotope ratios of tree-ring cellulose from oak (Quercus robur) at Lake Tiefer See, Mecklenburg Lake District, Northeastern Germany

Wood increment cores of 15 Quercus robur tree individuals were taken. Dendro-dated late wood from tree rings of 5 individuals was dissected (not pooled). After cellulose extraction and homogenization, 18O/16O-ratios of annually resolved samples were determined by Isotope Ratio Mass Spectrometry (IRMS). Time series of 18O/16O are given as delta-values versus VSMOW. Details can be found in the downloadable “data description” file.
