Stable_water_isotopes_2022
收藏资源简介：
The data set contains stable water isotope data measured on water extracted from (1) soil samples of different depths and (2) tree xylem of suberized twigs of 12 different trees. Samples were taken (1) with a Pürckhauer soil corer and (2) by tree climbers on RTG2300 plots 6.1, 6.2 and 6.3 during summer 2022 in weekly intervals and were extracted using cryogenic vacuum distillation. The obtained water samples were analyzed for the isotopic compositions of hydrogen and oxygen at the Center for Stable Isotope Research and Analysis (KOSI, Georg-August-University Göttingen, Germany), using a high temperature conversion analyzer (TC/EA, Thermo Electron Corporation, Bremen, Germany) coupled via a Con-Flo III interface to a Delta V Plus isotope ratio mass spectrometer (Thermo Electron Corporation, Bremen, Germany).
