AIMS Johnston Draw Continuous Stage and Discharge at Watershed Outlet Data (AIMS_MW_JDR_DISC)

This resource contains high-frequency stage and discharge data collected at the outlet of the Johnston Draw watershed, including conductivity, dissolved oxygen, turbidity, fluorescent dissolved organic matter, and temperature. Johnston Draw is a 1.8 km² watershed in southwestern Idaho, USA (outlet location: 43.1226, -116.776) located within the Reynolds Creek Critical Zone Observatory in western Idaho, a research center with cattle grazing. Elevation ranges from approximately 1,490 to 1,850 m. The mean annual precipitation in the watershed is 550 mm/yr with rainfall occurring at the lower elevations and snowfall, resulting in large drifts, at the higher elevations (Godsey et al., 2018). Mean annual temperature ranges from 8.9°C at the bottom of the watershed to 4.7°C near the top. These data were collected in support of the core sampling goals of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) Project. Between March 2022 and October 2024, stage and discharge were monitored at the watershed outlet (GSS01) at 15-minute intervals.

本数据集包含采自美国爱达荷州西南部约翰斯顿溪流域（Johnston Draw watershed）出口处的高频水位（stage）与流量（discharge）数据，监测指标涵盖电导率（conductivity）、溶解氧（dissolved oxygen）、浊度（turbidity）、荧光性溶解有机物（fluorescent dissolved organic matter）与温度。
约翰斯顿溪流域面积为1.8平方千米，其出口坐标为43.1226, -116.776，地处爱达荷州西部的雷诺溪临界带观测站（Reynolds Creek Critical Zone Observatory）内，该观测站为开展肉牛放牧研究的科研基地。流域海拔区间约为1490至1850米。流域年平均降水量为550毫米/年，低海拔区域以降雨为主，高海拔区域则多降雪且易形成大面积积雪漂移（Godsey等，2018）。流域内年平均气温从底部的8.9℃至上游近端的4.7℃不等。
本数据集的采集工作旨在支撑“溪流水文间歇性对微生物组的影响（Aquatic Intermittency effects on Microbiomes in Streams, AIMS）”项目的核心采样目标。2022年3月至2024年10月期间，研究人员以15分钟为间隔，对流域出口处的GSS01监测站点开展水位与流量连续监测。
