SSHCZO -- Soil Gas -- Garner Run (Sandstone Forested) -- (2015-2015)

The specific objectives of this experiment are to quantify variation in soil pCO2 and oxygen concentration at varying topographical positions in the two lithologies. The respiration and oxygen production in the soil will vary with microbial population and community. Eosense (previously Forerunner) CO2 concentration probes (eosGP) were used to measured in-situ soil CO2 concentration. Apogee Instruments oxygen sensors (SO-110) were used to measure in-situ soil oxygen concentration (%O2). Sensors were calibrated according to company documentation with site specific information. Sensors were deployed at two depths into soil pits at midslope location on opposite slopes. Sensors were wired to Campbell Scientific dataloggers with a program developed to measure the CO2 and O2 concentrations every hour and average every day.
