Hi Alison and all,
Sorry for the delay. I have been communicating with Jim Orr and Paul
Durack about your points, and have the following responses and proposal. I
am not sure what happens know, so please advise if you want to take the
discussion offline or have me put together a new revised spreadsheet.
Thanks, John

These terms are intended to allow users to construct a complete carbon
budget, and were not intended to distinguish between particulate and
dissolved. Should we restrict the definitions and add more terms? add
"total" to the name before "inorganic"? Please note that the names listed
above with "sedimentation" are incorrect. As they are intended to
represent loss from the ocean, they should not have "runoff_and". Like in
Paul's spreadsheet, they should just be "tendency_of_ocean_mole_content
_of_inorganic_carbon_due_to_sedimentation" and
"tendency_of_ocean_mole_content_of_organic_carbon_due_to_sedimentation".
These are effectively both "particulate" since they just represent pelagic
sinking in current models to my knowledge, though it is possible that
models might include insitu benthic organic production and/or inorganic
precipitation which could be represented as a dissolved loss. Of course,
"sediment dissolution" would be just dissolved, but runoff could be either
particulate or dissolved... did you want to distinguish between them?

While we are sensitive to your and Jonathan's point that it leads to
proliferation of variable names, we prefer the second option, particularly
in light of the variables that we are requesting daily as 2D sea surface
and monthly full 3D. If we are going to go this route, should these names
be
"sea_surface_mass_concentration_of_phytoplankton_expressed_as_chlorophyll_in_sea_water",
or just
"sea_surface_mass_concentration_of_phytoplankton_expressed_as_chlorophyll"

If you think this level of detail is necessary, I am fine with it, though
I'm not sure where it is being proposed the be entered (the comment?) it
seems inconsistent with the lack of detail on most variables. Editorially,
I think adding the fact that they are "single celled", and "prokaryotic or
eukaryotic" seem superfluous (e.g. the models intend to
represent diazotrophs, diatoms, and others groups even when they form
chains)", and "live near the water surface" would probably be better as
simply "grow".

I agree that the "due_to_natural_component" reference is potentially
misleading. In the simplest models it is envisioned as a separate tracer
in the same run - in the more complex BGC models where the biological
interactions are pH and/or saturation sensitive - such a tracer is an
approximation (analogue) of what one would get in a full control run, thus
give the moniker of the "natural"

Like for "natural", this is only an analogue of what would otherwise be a
solubility-driven tracer. To identify these as separate tracers more
clearly, I propose changing the comment and standard names to the following:
"Dissolved inorganic carbon (CO3+HCO3+H2CO3) concentration natural analogue
forced by preindustrial atmospheric xCO2"
mole_concentration_of_dissolved_inorganic_carbon_
natural_analogue_in_sea_water
"Dissolved inorganic carbon (CO3+HCO3+H2CO3) concentration abiotic analogue
ignoring biological effects on carbon and alkalinity"
mole_concentration_of_dissolved_inorganic_carbon_
abiotic_analogue_in_sea_water
Does that make more sense?
