Dear Roy

Thanks for clarification.

> pH_of_sea_water_defined_by_mole_concentration_of_hydrogen_ion_per_unit_mass (free scale)
> pH_of_sea_water_defined_by_mole_concentration_of_hydrogen_ion_per_unit_volume (NBS)

In other standard names, "mole concentration" means mol m-3. So the second
should be

> pH_of_sea_water_defined_by_mole_concentration_of_hydrogen_ion (NBS)

In existing names, we say "moles per unit mass" for mol kg-1. So the first is

> pH_of_sea_water_defined_by_moles_of_hydrogen_ion_per_unit_mass (free scale)

OK?

My main argument for plain pH_of_sea_water is that in many ocean models these
two quantities would be identical.

Cheers

Jonathan
