SSHCZO -- Stable Isotopes, Stream Water Chemistry -- Shale Hills -- (2008-2011)

Quality assured stream water stable isotope data has been prepared using Liquid Water Isotope Analyzer. Samples were analyzed following IAEA Standard Operating Procedure. Daily stream water samples were collected using ISCO Sampler at the stream outlet. Samples were plotted compared to the Local Meteoric Water Line (LMWL). Water samples were analyzed on DT-100 Liquid-Water Isotope Analyzer: http://www.lgrinc.com/analyzers/overview.php?prodid=16 IAEA Standard Operating Procedure was followed with in-house standards: http://www-naweb.iaea.org/napc/ih/documents/other/laser_procedure_rev12.PDF Deuterium (2H) and Oxygen-18 (18O) isotope values were calculated to within 1‰ and 0.2‰ respectively.本数据集为经质量管控的河流水稳定同位素数据，采用液态水同位素分析仪（Liquid Water Isotope Analyzer）完成制备。样品分析严格遵循国际原子能机构（International Atomic Energy Agency, IAEA）标准操作规程。每日河流水样通过ISCO Sampler于河流出水口处采集。将所得样品与本地大气降水线（Local Meteoric Water Line, LMWL）进行比对并绘图。水样使用DT-100型液态水同位素分析仪开展分析，仪器详情参见：http://www.lgrinc.com/analyzers/overview.php?prodid=16。分析过程采用内部标准物质并严格遵循国际原子能机构标准操作规程，规程文件详见：http://www-naweb.iaea.org/napc/ih/documents/other/laser_procedure_rev12.PDF。氘（²H）与氧-18（¹⁸O）的同位素值计算精度分别控制在1‰与0.2‰以内。
