The eosGP is a highly versatile carbon dioxide (CO2) concentration probe that can be used in soil and water. Vertical profiles of soil CO2 concentrations can be constructed by burying multiple eosGP sensors at varying depths. These profiles can be used to estimate soil pore space storage of CO2, track a number of biological and/or geochemical processes, and calculate CO2fluxes using the gradient method. Unlike discrete sampling approaches, the eosGP provides continuous measurements, allowing researchers to study temporal dynamics of CO2 in soils at various depths. This application note is intended as a guide for burying the eosGP in soil. It outlines three different burial methods and highlights the benefits and important considerations associated with each method.
