Statement

Table 3: Gas samples were analysed at the University of New Mexico. CH4, CO2, H2, and CO concentrations were measured using gas chromatography (GC) techniques. Ar, He, N2, and O2 were measured via quadrupole mass spectrometry (QMS). Analytical uncertainty for the GC measurements is at ±5%, and QMS analyses at <0.1% (concentration). Table S1: CO2-δ13C measurements were made at at INGV (Naples) and by Isotope Ratio Mass Spectrometer for seven samples at the Center for Stable Isotopes, UNM. Results for CO2-δ13C are shown in delta notation as per mil values (δ‰) relative to PDB (Pee Dee belemnite) and are characterized by a δ13C standard error of ±0.1‰.
