River and hyporheic zone water geochemical data from OsmoSamplers, East River Pumphouse, Colorado, Nov 2017-Sept 2018

This data package contains geochemical and river water temperature data from OsmoSamplers deployed at East River, Colorado pump house. There are three data files. The first one contains sulfate (SO4) and chloride (Cl) concentrations from riverwater and hyporheic zone (sediment water interface (SWI), 4 cm below seafloor (cmbsf), and 12 (cmbsf)). The second file contains methane concentrations, methane stable carbon isotope ratios and water isotopes from hyporheic zone porewaters. And the third is from a temperature logger during the deployment. Files are provided as .xls or .csv. This research was performed as part of the SBR funded project “Quantifying Subsurface Biogeochemical Variability in a High Altitude Watershed During Winter Isolation” DE-SC0018328. The novel part of this dataset is that we quantify these geochemical parameters throughout the winter isolation period, which is difficult to measure, as well as within the hyporheic zone. The data files were updated 3/1/2021 because the column label for the water isotopes was incorrect. Also, the csv files were also updated since they were not formatted correctly.

本数据包包含部署于科罗拉多州东河泵房的渗透压采样器（OsmoSampler）所采集的地球化学与河流水温数据。本数据集共包含三个数据文件：第一个文件涵盖河水与潜流带（沉积物-水界面（sediment water interface, SWI）、河底以下4厘米（cmbsf）及12厘米（cmbsf））中的硫酸盐（SO₄）与氯化物（Cl）浓度数据；第二个文件包含潜流带孔隙水中的甲烷浓度、甲烷稳定碳同位素比值与水体同位素数据；第三个文件为部署期间温度记录仪采集的水温数据。数据文件格式为.xls或.csv。本研究为SBR资助项目「量化高海拔流域冬季封冻期地下生物地球化学变异性」（DE-SC0018328）的组成部分。本数据集的创新之处在于，我们对冬季封冻期（该时段野外采样难度极大）以及潜流带内的各类地球化学参数进行了定量测定。由于水体同位素的列标签存在错误，本数据集文件已于2021年3月1日完成更新；此外，因CSV文件格式不符合规范，其版本也同步完成了更新。
