North Temperate Lakes LTER: High Frequency Meteorological and Dissolved Oxygen Data - Trout Bog Buoy 2003 - current

The instrumented buoy on Trout Bog is equipped with a dissolved oxygen sensor, a
thermistor chain, and meteorological sensors that provide fundamental information on lake
thermal structure, weather conditions, and lake metabolism. Data are usually collected every
10 minutes with occasional periods of 2 minute data for short periods to answer specific
questions. The D-Opto dissolved oxygen sensor is 0.5m from the lake surface, thermistors are
placed every 0.5-1m throughout the water column, and meteorological sensors measure wind
speed, wind direction, relative humidity, and air temperature. After correcting for flux to
or from the atmosphere and vertical mixing within the water column, high frequency
measurements of dissolved gases such as carbon dioxide and oxygen can be used to estimate
gross primary productivity, respiration, and net ecosystem productivity, the basic
components of whole lake metabolism. Sampling Frequency: varies for instantaneous sample.
