North Temperate Lakes LTER: High Frequency Dissolved Oxygen Data - Trout Lake Buoy2 - ADCP 2005

During the fall 2005, this instrumented buoy on Trout Lake was equipped with 4 Greenspan
dissolved oxygen sensors placed at depths from the lake surface to 10m. Parameters measured
at each depth included dissolved oxygen (DO), DO saturation and water temperature.
Currently, this buoy measures air temperature, relative humidity and various wind
parameters. It also is equipped with a thermistor chain that measures water temperature from
depths placed every 0.5-1m from the surface through 13m. 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. Dissolved oxygen (DO) data were collected for
period 27 Aug 2005 through 3 Nov 2005. Sampling Frequency: varies for instantaneous sample.
