Stable isotopes (δ18O, δ13C) and dissolved organic carbon (DOC) in ground ice on the Qinghai-Tibet Plateau, China

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.

对位于中国青藏高原东北部黄河源区的高分辨率地表冰记录进行了全面研究，该记录整合了深度为4.8米的稳定同位素（δ18O、δ13C）和溶解有机碳（DOC）数据。研究涉及两个冻土沼泽地（P-1、P-2）的数据，其分辨率为P-1的5cm（3米以下每10厘米一个数据点）和P-2的3cm。共获得δ18O和δD数据点62个和125个。在P-1中，分析了59个DOC数据和37个碳同位素（δ13C）数据。此外，对于P-2，分析了124个DOC数据和碳同位素（δ13C）数据。
