Radon Isotopes and Stable Water Isotopes from Coal Creek Watershed, Colorado (2021)

The radon isotope and stable water isotope data for Coal Creek Watershed, Colorado, consists of d2H, d18O, and 222Rn values from samples collected at 8 stream location along Coal Creek, samples from 7 groundwater springs within the watershed, and precipitation isotope samples collected by Next Generation Water Observing System (NGWOS) from a collector within the watershed. All stream and spring samples were collected between June and October, 2021, and precipitation isotope samples were collected between November 2020 and September 2021. These data were collected to evaluate how groundwater contributions to Coal Creek originating from a fractured hillslope and alluvial fan respond to summer monsoon rains and seasonal drying. Understanding of groundwater-surface water interactions in montane systems in critical for the future of water availability in the Western US as groundwater contributions are expected to become more important for sustaining summer stream flows. This data package contains: (1) a csv of all radon samples; (2) a csv of all stream and spring isotope samples; (3) a csv of precipitation isotope samples; and (4) a csv of locations for each sampling site. The dataset additionally includes a file-level metadata (flmd.csv) file that lists each file contained in the dataset with associated metadata; and a data dictionary (dd.csv) file that contains column/row headers used throughout the files along with a definition, units, and data type.

科罗拉多州煤溪流域（Coal Creek Watershed）的氡同位素与稳定水同位素数据集，涵盖沿煤溪布设的8个溪流采样点位获取的d2H、d18O及222Rn值样品、流域内7处地下水泉的样品，以及由下一代水观测系统（Next Generation Water Observing System, NGWOS）在流域内采集站点获取的降水同位素样品。所有溪流与泉水样品采集于2021年6月至10月期间，降水同位素样品则采集于2020年11月至2021年9月期间。本数据集旨在评估源自裂隙山坡与冲积扇的地下水对煤溪的补给量如何响应夏季季风雨与季节性干旱过程。理解山地系统中的地下水-地表水交互作用，对美国西部未来水资源可用性至关重要，因为地下水补给预计将在维持夏季溪流径流方面发挥愈发关键的作用。本数据包包含：(1) 所有氡同位素样品的CSV文件；(2) 所有溪流与泉水同位素样品的CSV文件；(3) 降水同位素样品的CSV文件；(4) 各采样点位信息的CSV文件。此外，数据集还附带文件级元数据文件（flmd.csv），该文件列出了数据集内所有文件及其关联元数据；以及数据字典文件（dd.csv），其中包含所有文件中使用的列、行表头信息，并附带其定义、单位与数据类型。
