North Temperate Lakes LTER: High Frequency Meteorological and Dissolved Oxygen Data - Crystal Bog Buoy 2005 - 2014

Abstract

The instrumented buoy on Crystal 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 0.25m throughout the water column, and meteorological sensors measure wind speed, 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
