Short-term CO2 emissions in the “hidden” geothermal system of Acoculco, Puebla (México) logged from eddy-covariance measurements: The natural emission baseline

The measurement of surface emissions of CO2 has become an important geochemical tool of volcanic and geothermal monitoring programmes. Temporal and spatial variations in CO2 emissions may show anomalous changes at depth, associated either with volcanic activity or geothermal processes. Eddy Covariance (EC) method has the capability to provide automated gas flux measurements without ground surface interferences, which are averaged with time, and logged from a larger spatial scale (m2 to km2). A fundamental link between such transient variations in deeply derived CO2 emissions, and meteorological and hydrological data require to be understood because these near-surface processes may control large changes in CO2 emissions (Lewicki et al., 2007). EC measurements of CO2 were assessed by comparing with those soil-gas fluxes coming from accumulation chamber (AC) methods over a period of 77 days to determine the natural “base-line” of gas emissions in the promissory hotdry rock geothermal system of Acoculco, Puebla (México). Acoculco has been defined as a “blind” or “hidden” geothermal system with a complex geology and high, spatial and temporal heterogeneous CO2 emissions.
