North Temperate Lakes LTER: High Frequency Meteorological and Dissolved Oxygen Data - Trout Bog Buoy 2003 - 2014

Abstract
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. averaged to hourly and daily values from one minute samples Number of sites: 1

North Temperate Lakes LTER: High Frequency Meteorological - Trout Lake Buoy2 - ADCP 2005 - 2006

Abstract
This instrumented buoy on Trout Lake is equipped with a thermistor chain and meteorological sensors that provide fundamental information on lake thermal structure, weather conditions, and lake metabolism. 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. The thermistors are placed every 0.5-1m from the surface through 13m, and meteorological sensors measure relative humidity, air temperature and wind parameters. In the fall of 2005, the buoy also included 4 Greenspan dissolved oxygen sensors placed at depths from the lake surface to 10m. 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
