Data in vol%. See text for details. <: below detection limits or not analyzed; ε: error of the isotopic determination reported for all of the R/Ra data. Carbon isotopic ratios are expressed as δ‰ units vs. PDB. δ¹³C_TDC and δ¹³C_CO2r: isotopic composition of the total inorganic carbon and recalculated gaseous CO₂, respectively.
