TL;DR: The accumulation chamber methodology allows one to obtain reliable values of the soil CO2 flux in the range 0.2 to over 10 000 g m−2 d−1, as proven by both laboratory tests and field surveys in geothermal and volcanic areas as discussed by the authors.

TL;DR: In this paper, the authors present a regional map of CO2 Earth degassing from a large area (most of central and south Italy) derived from the carbon of deep provenance dissolved in the main springs of the region.

TL;DR: In this article, the Solfatara volcano, 1 km far from Pozzuoli, releases 1500 t d−1 of hydrothermal CO2 through soil diffuse degassing from a relatively small area (0.5 km2).

TL;DR: In this paper, conditional sequential Gaussian simulations (sGs) have been applied for the first time to the study of soil diffuse degassing from different volcanic and nonvolcanic systems.

TL;DR: In this paper, the authors estimate that 6.5×1010 mol yr−1 of inorganic carbon are dissolved in the studied aquifers and approximately 23% of this amount derives from biological sources active during the infiltration of the recharge waters, 36% comes from carbonate dissolution, while 41% is representative of deep carbon sources characterized by a common isotopic signature.
