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.

本数据集采集了15株夏栎（Quercus robur）的树木生长钻芯。对其中5株的年轮晚材进行树木年代学定年后实施单独剖分（未混样）。经纤维素提取与均质化处理后，采用同位素比值质谱仪（Isotope Ratio Mass Spectrometry, IRMS）测定了年分辨率样品的¹⁸O/¹⁶O同位素比值。所有¹⁸O/¹⁶O的时间序列均以相对于维也纳标准平均海水（Vienna Standard Mean Ocean Water, VSMOW）的δ值形式给出。详细信息可查阅可下载的"数据说明"文件。
