Dear Roy, Thank you for the fast reply.
My first comment is that either this Standard Name should be changed to mass_concentration_of_dissolved_inorganic_nitrogen_in_sea_water with references to 'inorganic nitrogen' in the definition changed to 'dissolved inorganic nitrogen' or your proposal should lose the 'dissolved'. My preference would be to have 'dissolved' in both Standard Names. Would you agree?
I agree - it should be consistent for both names - and my preference is the same.
My second comment is that whilst your proposal is for the 'mole_concentration' analogue to mass_concentration_of_inorganic_nitrogen_in_sea_water, your definition text whilst based on its definition, has been subtly changed with the first sentence removed. Was this intentional and if so why? Your proposal for iron looks fine to me.
Thanks for pointing it out. It was not intentional. I missed the sentence. The description should actually be:
"molarity", and is used in the construction "mole_concentration_of_X_in_Y", where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". "Dissolved inorganic nitrogen" describes a family of chemical species which, in an ocean model, usually includes nitrite, nitrate and ammonium which act as nitrogen nutrients. "Dissolved inorganic nitrogen" is the term used in standard names for all species belonging to the family that are represented within a given model. The list of individual species that are included in a quantity having a group chemical standard name can vary between models. Where possible, the data variable should be accompanied by a complete description of the species represented, for example, by using a comment attribute.

Dear Daniel, We already have a 'mass_concentration_of_inorganic_nitrogen_in_sea_water, in which 'inorganic nitrogen' is defined as: 'Inorganic nitrogen' describes a family of chemical species which, in an ocean model, usually includes nitrite, nitrate and ammonium which act as nitrogen nutrients. 'Inorganic nitrogen' is the term used in standard names for all species belonging to the family that are represented within a given model. The list of individual species that are included in a quantity having a group chemical standard name can vary between models. Where possible, the data variable should be accompanied by a complete description of the species represented, for example, by using a comment attribute.'

There exists no standard name for the first (DIN) yet. Reason for iron: There is a "tendency_of_ocean_mole_content_of_dissolved_inorganic_*" standard name existing for iron but no molar concentration. For completeness, I would like to add a standard name for mole concentration of inorganic iron in sea water. Further, I would like to suggest to remove a typo in "tendency_of_ocean_mole_content_of_dissolved_inorganic_nitrogen". Currently, the last sentences of its description reads 'Where possible, the data variableshould be accompanied by a complete description of the species represented, for example, by using a comment attribute.'. There is a space missing 'variableshould'. The full descriptions are given below (combined from existing description of other "mole_concentration_of_dissolved_inorganic_*" and "tendency_of_ocean_mole...nitrogen/iron"). Regards, Daniel Name: mole_concentration_of_dissolved_inorganic_nitrogen_in_sea_water Description: Mole concentration means number of moles per unit volume, also called "molarity", and is used in the construction "mole_concentration_of_X_in_Y", where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". "Dissolved inorganic nitrogen" is the term used in standard names for all species belonging to the family that are represented within a given model. The list of individual species that are included in a quantity having a group chemical standard name can vary between models. Where possible, the data variable should be accompanied by a complete description of the species represented, for example, by using a comment attribute. Unit: mol m-3 Name: mole_concentration_of_dissolved_inorganic_iron_in_sea_water Description: Mole concentration means number of moles per unit volume, also called "molarity", and is used in the construction "mole_concentration_of_X_in_Y", where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". "Dissolved inorganic iron" means iron ions, in oxidation states of both Fe2+ and Fe3+, in solution.
