North Temperate Lakes LTER: High Frequency Water Temperature Data - Trout Lake Buoy2 - ADCP 2005 - 2006

Abstract
This instrumented buoy on Trout Lake is equipped with a thermistor chain that measures water temperature from depths placed every 0.5-1m from the surface through 13m. The Trout Lake buoy is also equipped with meteorological sensors that provide fundamental information on lake thermal structure and weather conditions. An acoustic Doppler current profiler (ADCP) is associated with this buoy. Data are usually collected every 10 minutes with occasional periods of 2 minute data for short periods to answer specific questions. 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. averaged to hourly and daily values from one minute samples Number of sites: 1
