Chloride Concentrations, Conductivity, and Water Temperature Data from Lake Mendota and Lake Monona Madison, WI: December 2019 – April 2021

Conductivity and chloride were measured for 2 years in Lake Mendota and Lake Monona in Madison, WI. Conductivity was continuously measured (every 30 minutes) on under-ice buoys in the eplimnia (1-2m below the surface) and hypolimnia (1m off the bottom of the lake) of the lakes. Depth-discrete chloride grab samples were collected from the lakes quarterly. Profile sampling in Mendota, which is approximately 25 m deep, occurred every 5m from 0-20m and at 23.5m. Profile sampling in Monona, which is approximately 21m deep, occurred every 4m from 0-20m. This data was needed for a master’s research thesis with the goal of identifying the lakes' mixing dynamics and how salinization may impact them.

针对美国威斯康星州麦迪逊市的门多塔湖（Lake Mendota）与莫诺纳湖（Lake Monona），本研究开展了为期两年的电导率与氯化物检测工作。电导率通过冰下浮标连续监测，采样间隔为30分钟，监测点位分别设置于两座湖泊的上层温水层（eplimnia，表层下1~2米处）与下层湖水区（hypolimnia，距湖底1米处）。研究人员按季度采集两座湖泊的分层离散氯化物瞬时水样。其中，水深约25米的门多塔湖，剖面采样范围为0~20米，每5米设置一个采样点，另在23.5米处增设采样点位；水深约21米的莫诺纳湖，剖面采样范围为0~20米，每4米设置一个采样点。本数据集源自一篇硕士学位论文的研究内容，旨在解析两座湖泊的混合动力学机制，以及盐化作用对湖泊混合过程的潜在影响。
