IMLCZO -- Surface Water Chemistry -- Surface Water -- Monticello, Illinois -- (2017-2018)

Site ID: #111 Monticello Datasets contain water quality data collected by two YSI sondes deployed in PVC tubes mounted on the slope of the downstream side of the W. Bridge Street bridge in Monticello, IL near USGS River Station 05572000. Coordinates: 40deg 1'51.37N 88deg35'18.32W WGS84 -YSI 6600EDS-O sonde Sensors: 6560 Conductivity/Temperature probe, 6136 Turbidity probe Data collected (direct): temperature (*C), conductivity (mS/cm), turbidity (NTU) Data collection start: 03/24/2017 (currently deployed) -YSI 600OMS-O sonde Sensors: Integrated conductivity/temperature probe, 6150+ ROX DO probe Data collected (direct): temperature (*C), conductivity (mS/cm), dissolved oxygen (mg/L) Data collection start: 04/20/2017 (currently deployed) -Sondes cannot be deployed if stage drops below ~5.5ft at Monticello as the sensors will not be submerged. -Data collection interval: 03/24/2017 - 08/4/2017 every 30 minutes; changed to every 15 minutes on 08/4/2017 to match collection frequency of USGS gaging station 05572000 at Monticello: https://waterdata.usgs.gov/il/nwis/uv?site_no=05572000. Between 08/21/2017-11/30/2017 there were few rain events and stage was consistently between 4-5 ft; sondes were deployed for 30-45 min periods to gather some data during this dry season.

蒙蒂塞洛数据集（Site ID: #111）收录了由两台YSI探针采集的水质数据，这些探针安装在伊利诺伊州蒙蒂塞洛市W.大桥街桥下游侧的PVC管中。坐标为：北纬40度1分51.37秒，西经88度35分18.32秒，WGS84坐标系。YSI 6600EDS-O探针配备6560型电导率/温度探头和6136型浊度探头。收集的数据（直接）：温度（摄氏度）、电导率（毫西门子/厘米）、浊度（NTU）。数据收集开始时间：2017年3月24日（目前仍在部署）。YSI 600OMS-O探针配备集成的电导率/温度探头和6150+ ROX溶解氧探头。收集的数据（直接）：温度（摄氏度）、电导率（毫西门子/厘米）、溶解氧（毫克/升）。数据收集开始时间：2017年4月20日（目前仍在部署）。当蒙蒂塞洛水位下降至约5.5英尺以下时，探针无法部署，因为传感器将无法完全浸没。数据收集间隔：2017年3月24日至8月4日，每30分钟收集一次；自2017年8月4日起，改为每15分钟收集一次，以匹配蒙蒂塞洛USGS河站05572000的采集频率：https://waterdata.usgs.gov/il/nwis/uv?site_no=05572000。在2017年8月21日至11月30日期间，降雨事件较少，水位持续保持在4至5英尺之间；探针在干旱季节以30至45分钟的周期部署，以收集一些数据。
