West Okoboji Lake Monitoring Buoy: High Frequency Oxygen, Temperature, Water Quality and Weather Data 2015-2021

High frequency weather and limnological data from the West Okoboji Lake monitoring buoy, Iowa, USA, from 2015 - 2021. The West Okoboji Lake (Global Lake Ecological Observatory Network—GLEON) instrumented monitoring buoy is operated by the Iowa Lakeside Laboratory (https://iowalakesidelab.org/). The buoy is equipped with a thermistor chain and dissolved oxygen probes the measure every 2 meters from 1m to 25m in depth, a multi-parameter sonde at 1 meter depth, as well as a weather station situated on the buoy. All data in this data package have been QAQC'd to remove obviously errant readings, highly suspicious readings, and artifacts of buoy maintenance. Because of this, as well as sensor errors and failure, not all data is available at every point each year. Measured parameters in the data set include water temperature, dissolved oxygen concentration, and dissolved oxygen saturation (measured every 2 meters from 1m to 25m). Other measured parameters include pH and specific conductive in the surface water, as well as weather station data including wind, rain, air temperature and humidity. Sampling Frequency: Parameters are measured at 10 minute intervals, and most years include measurements from mid/late May through October. Measurements were stopped in the fall once the lake had turned over.

美国爱荷华州西奥科博吉湖监测浮标2015年至2021年高频气象与湖沼学数据集。西奥科博吉湖配套的仪器化监测浮标隶属于全球湖泊生态观测网络（Global Lake Ecological Observatory Network, GLEON），由爱荷华湖畔实验室（https://iowalakesidelab.org/）负责运维。该浮标搭载热敏电阻链（thermistor chain）与溶解氧探头（dissolved oxygen probes），沿1米至25米水深以每2米的间隔布设监测节点；同时在1米水深处安装多参数水质探头（multi-parameter sonde），浮标本体还集成了一套气象站。本数据包内所有数据均经过质量保证与质量控制（QAQC），以剔除明显错误、高度可疑的读数以及浮标维护产生的伪数据。受传感器故障、失效等因素影响，并非每年的所有采样点位均可获取完整有效数据。数据集涵盖的实测参数包括：沿1米至25米水深每2米采集的水温、溶解氧浓度及溶解氧饱和度；表层水体的pH值与比电导率（specific conductivity），以及气象站采集的风速、降雨量、气温与相对湿度等气象数据。采样频率为每10分钟采集一次，多数年份的监测周期为5月中下旬至10月，当湖泊发生秋季分层翻转后即停止采样。
