Title Tree ring oxygen isotope in Greenland
Creator Chenxi Xu
Subject Tree ring oxygen isotope data
Publisher Xiukuan Zhao
Description Cellulose oxygen isotope from four trees (Sample ID: QUN24, 25, 30 and 45) in southern Greenland were measured using an isotope ratio mass spectrometer (Delta V Advantage, Thermo Electron Corporation, Bremen, Germany) interfaced with an elemental analyzer (TC/EA) at the Research Institute for Humanity and Nature, Japan. Oxygen isotope results are presented in δ notation as the per mil (‰) deviation from Vienna Standard Mean Ocean Water.

Date The data covers the period of 1950-1999 with annual resolution.
Type Year: the time of each tree ring formation
QUN24, 25, 30 and 45 are ID number for four trees
QUN24-d18o, 25-d18o, 30-d18o and 45-d18o indicates cellulose oxygen isotope from these four trees, respectively.
