North Temperate Lakes LTER: High Frequency Water Temperature Data - Lake Mendota Buoy 2006 - current

The instrumented buoy on Lake Mendota is equipped with a thermistor chain that measures water temperature. In 2006, the thermistors were placed every half-meter from the surface through 7m, and every meter from 7m to 15m. Since 2007, the thermistors were placed every half-meter from the surface through 2m, and every meter from 2m to 20m. The sensor at the water surface is as close to the surface as feasible. A list of sensors used since the first deployment in 2006 is provided as a downloadable CSV file. Hourly and daily water temperature averages are computed from high resolution (1 minute) data.The buoy is removed during the winter when the lake is ice-covered (typically Dec-Apr). Meteorological and limnological data collected at the same buoy site can be found in an ancillary dataset. Sampling Frequency: one minute. Number of sites: 1. Location lat/long: 43.0995, -89.4045 Notes: The thermistor string failed in June 2014, so there is not data between June 17, 2014 and the start of the 2016 season. The thermistor string failed again in August 2023. It was replaced by Hobo temp loggers at 0, 5,10, 15, 20 meters depth for the remainder of 2023.
