Yang, Yuzhong: Stable isotopes (δ18O, δ13C) and dissolved organic carbon (DOC) in ground ice on the Qinghai-Tibet Plateau, China [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.920700 (dataset in review)
Abstract:
The high-resolution ground ice records, integrating the stable isotope (δ18O, δ13C) and dissolved organic carbon (DOC) at a depth of 4.8m, are comprehensively investigated from two frozen peat sites (P-1, P-2) in the Source Area of Yellow on the northeastern Qinghai-Tibet Plateau (QTP), China. The resolution is 5cm for P-1 (every 10 cm below 3 m) and 3cm for P-2. Totally, 62 and 125 of δ18O and δD data points are obtained. A total of 59 DOC data and 37 carbon isotopes (δ13C) data are analyzed in P-1. In addition, 124 of DOC and carbon isotopes (δ13C) data are analyzed for P-2.
