Semi-continuous pressure and water quality sensor data from 5 locations in Lower Pool 13 of the Upper Mississippi River from May - September 2024

The U.S. Geological Survey Upper Midwest Environmental Sciences Center collected semi-continuous data from water quality and pressure sensors at four shallow locations in the impounded portion of Pool 13 of the Upper Mississippi River and one location upstream near Savanna, IL between late May and early September 2024. This dataset includes high-frequency conductivity, salinity, total dissolved solids, temperature, dissolved oxygen, and turbidity measurements every 5-minutes at five locations, with chlorophyll-a and phycocyanin concentrations being recorded at two of those locations using YSI EXO3 water quality sensors. Pressure data was recorded in bursts every 30-minutes alongside water quality at four locations using RBR virtuoso3 and Nortek Vector sensors to obtain information on local water depth and waves. Due to differing sampling frequencies, data files are grouped by sensor type.

美国地质调查局（U.S. Geological Survey）上中西部环境科学中心于2024年5月末至9月初，在密西西比河上游13号池（Pool 13）的蓄水区4处浅测点，以及伊利诺伊州萨凡纳附近的1处上游测点，通过水质与压力传感器采集了半连续观测数据。本数据集涵盖5个测点每5分钟一次的高频观测数据，包括电导率、盐度、总溶解固体、水温、溶解氧及浊度；其中2个测点搭载YSI EXO3水质传感器，同步记录了叶绿素a与藻蓝蛋白浓度。另有4个测点采用RBR virtuoso3与Nortek Vector传感器，每30分钟突发采集一次压力数据，以同步获取当地水深与波浪信息。由于各传感器采样频率存在差异，数据集按传感器类型进行分组存储。
