Talladega Stream Temperature, Intermittency, and Conductivity Data (AIMS_SE_TAL_STIC)

This resource includes Stream Temperature, Intermittency, and Conductivity (STIC) data collected from the Talladega research watershed (outlet location: 33.76219799, -85.59550775) in the Talladega National Forest (Cleburne County, AL, USA). The watershed drains a non-perennial unnamed tributary of Pendergrass Creek, and contains 0.92 km^2 of mixed coniferous and deciduous forest in the Piedmont Upland physiographic province. Located near Anniston, AL, the watershed spans an elevation range from 345 to 456 m above sea level and is a tributary to the Coosa River (within the larger Mobile-Tombigbee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 5.3°C and 25.3°C respectively, and mean annual precipitation of 1400 mm/yr. These data were collected in support of the sampling goals of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) Project. 20 STIC loggers were placed along the Talladega watershed and collected data from Sep. 2021 through Oct. 2024, with an additional 29 sensors collecting the same data at the same time interval from May 2022 through Apr. 2023. We deployed these additional sensors to get a more detailed dataset for a spatially-distributed synoptic sampling event, when a field team co-collected datasets characterizing the hydrology, biogeochemistry, and ecology across all 49 locations within the Talladega watershed. These sensors were set to collect temperature and conductivity data every 15 minutes starting from Sep. 2021 through Apr. 2024, and every 1 hour from May to Oct. 2024. The raw conductivity data were used to classify the timeseries into wet or dry readings at each timestep. Each .csv file is associated with a single site for a single year. Also included is a “ReadMe” file that includes author information, column descriptions, and site locations.本数据集包含从美国阿拉巴马州克莱本县塔拉迪加国家森林内的塔拉迪加研究流域（出水口坐标：33.76219799, -85.59550775）采集的溪流温度、间歇性与电导率（Stream Temperature, Intermittency, and Conductivity，STIC）数据。该流域汇水区域为彭德格拉斯溪的一条无名非常年支流，地处皮德蒙特高原地貌大区，覆盖0.92平方千米的针阔混交林。流域毗邻阿拉巴马州安尼斯顿市，海拔范围为345至456米，是科萨河（隶属于更大的莫比尔-通比格比流域）的支流。该区域属亚热带湿润气候，1月和7月的日均气温分别为5.3°C与25.3°C，年平均降水量为1400毫米/年。 本数据集采集工作服务于"溪流微生物组的水生间歇性效应（Aquatic Intermittency effects on Microbiomes in Streams，AIMS）"项目的采样目标。研究团队在塔拉迪加流域内布设了20台STIC记录仪，于2021年9月至2024年10月期间采集数据；另有29台额外传感器于2022年5月至2023年4月期间以相同时间间隔开展同步数据采集。布设额外传感器的目的是为空间分布的全域采样事件提供更精细的数据集，彼时野外团队同步采集了塔拉迪加流域内全部49个点位的水文、生物地球化学与生态学相关数据。 这些传感器设置为于2021年9月至2024年4月期间以15分钟的间隔采集温度与电导率数据，2024年5月至10月期间调整为每1小时采集一次。原始电导率数据被用于将每个时间步的时序数据划分为湿润或干燥读数。每个.csv文件对应单个监测点位的单一年度数据。数据集还包含一份"ReadMe"说明文件，其中包含作者信息、各列数据说明以及点位坐标信息。
