The waterproof Eosense eosGP CO2 probe measures CO2 concentration in the soil through diffusive equilibration with the soil air-filled and water-filled pore space. These measurements are most often used as part of the gradient method to calculate CO2 effluxes, but may also be used to estimate pore space storage of CO2 and track a number of biological and geochemical processes (e.g. carbonate weathering). In this application note the various methods of burying the eosGP in a soil medium will be discussed.
