SSHCZO -- Soil Gas -- Soil Gas Sample (O2 and CO2) -- Shale Hills -- (2015-2018)

Hourly automated sampling of O2 and CO2 in soils of the south planar midslope of Shale Hills This automated gas collection is ongoing as part of the larger GroundHOG dataset that includes soil gas, soil moisture, and pore water chemistry. These automated soil gas measurements are taken from a surface and subsurface horizon at each of the sites. These data provide key information on predominate weathering processes, microbial respiration, and tree root activity.
