Spring and stream sampling across Coal Creek watershed during summer of 2021 (June-October) to estimate groundwater chemistry.

Sampled Approximately weekly for synoptic sampling of Coal Creek during summer to assess locations of groundwater discharge to stream. Data shows intermittent spring (IS) and surface water (SW) chemistry - to study Surface and groundwater interactions.

- Abstract
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.

2021年夏季（6月至10月），研究团队于煤溪流域开展河流与泉水采样工作，以表征地下水化学特征。

夏季期间，研究团队每周对煤溪开展同步采样，以评估地下水向溪流排泄的点位。本数据集包含间歇性泉水（Intermittent Spring，IS）与地表水（Surface Water，SW）的化学组分数据，用于研究地表水与地下水的交互作用。

有关同位素数据，请参阅下方ESS DIVE链接：
- 摘要
科罗拉多州煤溪流域的氡同位素与稳定水同位素数据集，涵盖沿煤溪布设的8个采样点位的δ²H、δ¹⁸O及²²²Rn值、流域内7处地下水泉水样品，以及由下一代水观测系统（Next Generation Water Observing System，NGWOS）在流域内采集器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，降水同位素样品采集时段为2020年11月至2021年9月。
本数据旨在评估源自裂隙山坡与冲积扇的地下水补给对夏季季风雨及季节性干旱的响应。随着地下水补给对维持夏季溪流流量的重要性日益凸显，明晰山地系统中的地表水-地下水交互作用，对美国西部未来水资源可用性保障至关重要。
本数据包包含：
1. 所有氡样品的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. 各采样点位位置信息的CSV文件。
此外，数据集还包含文件级元数据文件（flmd.csv），列明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），收录所有文件中使用的列/行表头及其定义、单位与数据类型。
