  1. Literature data used to construct this table are provided in Supplementary information. Here, we report values for the median, first (Q1) and third (Q3) quartiles of each data set (\({{\rm{Median}}}_{Q3-Median}^{Median-Q1}\), see methods). Concentrations for the ESR and BM are normalized to the mass of the corresponding reservoir, reported in bold beneath the column headers43. Given the large uncertainties and limited amount of measurements, the water content in EC is provided as a range of extreme values reported in the literature79,80,81. Note that noble gas elemental ratios may not be derived from this table; we recommend computing average values of compiled ratios (as done here for EC, see supplementary information), rather than ratios of median values.
