| Abstract: | SAFE Intensive Carbon Plots, part of the Global Ecosystem Monitoring (GEM) network, see http://gem.tropicalforests.ox.ac.uk/
Total soil respiration is measured at 25 points per plot, in the middle of each subplot (16 points per plot in OP, in subplot corners), using 12 cm diameter PVC collars inserted into approximately 5 cm depth
Partitioned respiration is measured at four points per plot, a using a cluster of six collars (see below)
Disturbance experiment in the plot centre
All the methods and installation is described in detail in the GEM Intensive Carbon Plots manual, available at http://gem.tropicalforests.ox.ac.uk/files/rainfor-gemmanual.v3.0.pdf
The aim is to measure monthly, but in practice the measurement interval is almost always longer (problems with access, staffing and instruments)
EGM-4 infrared CO2 analyser and SRC-1 respiration chamber (PP Systems)
Chamber closure time is 124 seconds, CO2 concentration inside the chamber is recorded every 5 s. Flux is calculated from the linear change in concentration in the chamber headspace SAFE Intensive Carbon Plots, part of the Global Ecosystem Monitoring (GEM) network, see http://gem.tropicalforests.ox.ac.uk/ Total soil respiration is measured at 25 points per plot, in the middle of each subplot (16 points per plot in OP, in subplot corners), using 12 cm diameter PVC collars inserted into approximately 5 cm depth Partitioned respiration is measured at four points per plot, a using a cluster of six collars (see below) Disturbance experiment in the plot centre All the methods and installation is described in detail in the GEM Intensive Carbon Plots manual, available at http://gem.tropicalforests.ox.ac.uk/files/rainfor-gemmanual.v3.0.pdf The aim is to measure monthly, but in practice the measurement interval is almost always longer (problems with access, staffing and instruments) EGM-4 infrared CO2 analyser and SRC-1 respiration chamber (PP Systems) Chamber closure time is 124 seconds, CO2 concentration inside the chamber is recorded every 5 s.
