North Temperate Lakes LTER: High Frequency Water Temperature Data - Sparkling Bog North Buoy 2008 - 2012

The instrumented buoy on Sparkling Bog North is equipped with a thermistor chain that
measures water temperature at the surface, at 0.25 m and at every .5 m from 0.5 m to 4.5 m.
The buoy is also equipped with a dissolved oxygen sensor, meteorological sensors, a CO2
sensor and a YSI AutoProfiler that provide fundamental information on lake thermal
structure, weather conditions, and lake metabolism. Prior to May 2009, data were collected
at 1 minute or 10 minute intervals. Since May 2009, data are being collected each minute.
Hourly and daily water temperature averages are computed from high resolution data. Hourly
and daily values may not be current with high resolution data. In 2008, the instrumented
buoy was deployed in Sparkling Bog North from March 24 to November 10. In 2009, the buoy was
deployed on the ice on March 7 and was not removed for the winter of 2009 to 2010. Sampling
Frequency: varies for instantaneous sample. Generally 1 minute or 10 minutes. Number of
sites: 1
