North Temperate Lakes LTER: High Frequency Water Temperature Data - Crystal Bog Buoy 2005 - current

The instrumented buoy on Crystal Bog is equipped with a thermistor chain that measures water temperature from depths ranging from the surface to 2.25 m placed every 0.25m throughout the water column. From the initial deployment in 2005 through 2014, a surface buoy was used in the open water season. Since 2017, a subsurface buoy has been used, including under-ice deployments during the winter.
