Spatial Study 2021: Sensor-Based Time Series of Surface Water Temperature, Specific Conductance, Total Dissolved Solids, Turbidity, pH, and Dissolved Oxygen from across Multiple Watersheds in the Yakima River Basin, Washington, USA

This dataset supports a broader study examining the drivers of spatial variability in sediment respiration rates in the Yakima River Basin. We acknowledge the Yakama Nation as owners and caretakers of the lands where we collected the data used in this project. We thank the Confederated Tribes and Bands of the Yakama Nation Tribal Council and Yakama Nation Fisheries for working with us to facilitate sample collection and optimization of data usage according to their values and worldview. The dataset provides two-hour time series hydrological and water chemistry sensor data, manual chamber open channel respiration data, handheld sensor water chemistry data, river substrate grain size photos, general environmental context photos, and field metadata (including qualitative information on instream and river corridor characteristics) collected during the same two-week period at 47 sites in multiple rivers throughout the Yakima River Basin in Washington, USA. Grain size photos can be used to improve estimates of channel substrate D50 data. In addition to the sensor data, there are plots of two-hour time series sensor data and R scripts used to generate the plots. Related sample-based water chemistry data will be published separately and can be used to link sediment respiration rates to biogeochemical processing rates. This dataset is comprised of four main folders, one containing three sensor-specific subfolders and the others containing photographs. The SFA_SpatialStudy_2021_SensorData main data folder includes file-level metadata (FLMD), data dictionary (dd), installation methods, field metadata, manual summary data, field data collection protocols, R scripts for creating plots, international geo-sample number (IGSN) mapping file, and a readme file. Each sensor subfolder (BarotrollAtm, MantaRiver, and MinidotManualChamber) contains a sensor data subfolder and a subfolder for plots and summary statistics. The BarotrollAtm Data subfolder contains In Situ Rugged BaroTROLL pressure and temperature data. The MantaRiver Data subfolder contains Eureka Manta+ 35B multisonde temperature, specific conductance, turbidity, and pH data. The MinidotManualChamber Data subfolder contains PME MiniDOT Logger dissolved oxygen (mg/L and percent saturation) and temperature data. The folder SFA_SpatialStudy_2021_EnvironmentalContextPhotos contains environmental context photographs and videos. The folders SFA_SpatialStudy_2021_SedimentQuadratPhotos_Part1 and SFA_SpatialStudy_2021_SedimentQuadratPhotos_Part2 contain sediment quadrat photographs. All files are .csv, .pdf, .R, .jpg, .jpeg, .mp4, or .mov. This data package was originally published in September 2022. It was updated in January 2023. See the change history section in the data package readme for more details.

本数据集支撑一项更广泛的研究，该研究聚焦美国亚基马河流域（Yakima River Basin）沉积物呼吸速率的空间变异驱动因子。我们谨致谢忱，亚基马部落（Yakama Nation）为本次研究数据采集所在土地的所有者与管护者。感谢亚基马部落议会下属的联合部落与班德联盟（Confederated Tribes and Bands of the Yakama Nation Tribal Council）以及亚基马部落渔业部门，依据其自身价值观与世界观，协助我们完成样本采集工作并优化数据使用方式。
本数据集涵盖美国华盛顿州亚基马河流域多条河流的47个采样点在同期两周内采集的多类数据，具体包括：两小时间隔的水文与水化学传感器时序数据、手动明渠箱式呼吸室呼吸测量数据、手持式传感器水化学数据、河流底质粒径照片、基础环境背景照片，以及野外元数据（包含河道与河流廊道特征的定性信息）。其中，底质粒径照片可用于优化河道底质D50的估算精度。
除原始传感器数据外，本数据集还包含两小时间隔传感器时序数据的可视化图表，以及用于生成该图表的R脚本。相关基于样本的水化学数据将另行发布，可用于关联沉积物呼吸速率与生物地球化学过程速率。
本数据集共包含四个主文件夹：其中一个主文件夹下设三个传感器专属子文件夹，其余三个主文件夹分别存放各类照片。主文件夹SFA_SpatialStudy_2021_SensorData包含文件级元数据（File-level Metadata, FLMD）、数据字典（data dictionary, dd）、设备安装指南、野外元数据、手动汇总数据、野外数据采集规程、绘图专用R脚本、国际地理样本编号（International Geo-sample Number, IGSN）映射文件，以及说明文档（readme）。每个传感器子文件夹分别为BarotrollAtm、MantaRiver与MinidotManualChamber，均下设传感器数据子文件夹与图表及汇总统计性子文件夹。其中：BarotrollAtm数据子文件夹包含原位坚固型BaroTROLL压力与温度数据；MantaRiver数据子文件夹包含Eureka Manta+ 35B多参数水质仪的温度、比电导率、浊度与pH数据；MinidotManualChamber数据子文件夹包含PME MiniDOT Logger溶解氧（单位：mg/L与饱和度百分比）与温度数据。主文件夹SFA_SpatialStudy_2021_EnvironmentalContextPhotos存放环境背景照片与视频。主文件夹SFA_SpatialStudy_2021_SedimentQuadratPhotos_Part1与SFA_SpatialStudy_2021_SedimentQuadratPhotos_Part2则存放沉积物样方照片。所有文件格式为.csv、.pdf、.R、.jpg、.jpeg、.mp4或.mov。
本数据包最初于2022年9月发布，并于2023年1月完成更新。详细更新历史请参阅数据包说明文档中的变更记录章节。
