Gas calculations are based on solubilities determined using marine air and are subject to uncertainties derived from determination of their actual atmospheric concentration. Assumed atmospheric dry partial pressures are adapted from NOAA:
Nitrogen = 78.084 %
Oxygen = 20.946 %
Argon = 0.934 %
Carbon dioxide = 0.042* %
Neon = 18.182 ppmV
Helium = 5.24 ppmV
Methane = 1.92* ppmV
Krypton = 1.14 ppmV
Hydrogen = 0.55* ppmV
Carbon Monoxide = 0.10* ppmV
Xenon = 0.087 ppmV
*known to have considerable variability
