Statement

Gas sampling was performed by inserting a soil probe or burying an inverted funnel over an active gas vent. The gas was pumped slowly from the gas vent into 1L gas-tight glass vessels through a drying agent filled with Mg(ClO4)2. Three samples were collected in Isotubes. Both the vessel and the Isotubes were flushed with 3 volumes of gas before it was collected. Three samples were sampled directly at the main gas vents, whereas an additional two were sampled in the vicinity of the main gas vents from soil gas. Major gas composition of the FA and ROC samples was measured on a gas chromatograph at GFZ. Carbon isotopes (δ13C) of CH4 and CO2 were measured on a MAT 253 GC-IRMS at GFZ. Methane clumped isotope analyses are conducted on a Thermo Scientific IRMS-253 Ultra.
