Sampling, Processing and Quality Control Methods

Step by Step Procedures
Step 1:  
Description:

Dark Chamber Manual CH4 flux measurements

Dark Al chambers (150 L) placed into water sealed collars (0.397 m2). Mylar covers were used to reduce chamber heating. Five grab samples (total of 250 ml maximum, 0.17%26#37; of volume) taken from the enclosed headspace every 4 minutes and analyzed by gc-fid. Precision was 0.2%26#37; at near ambient mixing ratios. Flux is the vol/area weighted change in the CH4 mixing ratio over the time of enclosure.

Sampling Area And Frequency:
Fluxes were taken at irregular intervals of a few days to a few weeks from Jan 1994 until Sept 2001.
Sampling Description:
The data are daily averages of fluxes made on 4 to 9 different sites within the 1.7 ha Fen.
