Hi,
Thanks for correction. I realized that I need a standard name not only
for silicate but for biogenic silica plus silicate. I updated the
proposed name and description as follows:
moles_of_silicon_per_unit_area_in_seabed_sediment
unit: mol/m2
description: moles_of_X_per_unit_area_in_Y describes the amount of X in
a column with unity base area of material/compartment Y. 'Seabed
sediment' means particulate matter bound at the sea floor including
interstitial pore water. Information on the location of the interface
between water column and sediment can be provided via the comment
attribute. 'Silicon' summarizes 'dissolved inorganic silicon' and
'biogenic silica'. 'Dissolved inorganic silicon' means the sum of all
inorganic silicon in solution (including silicic acid and its first
dissociated anion SiO(OH)3-). 'Biogenic silica' are biogenic silicon
minerals which originate from the siliceous skeletal material of dead
diatoms and other silica-utilizing organisms.

Hi (yet) again,
Overnight I remembered a debate on CF about not using'dissolved
inorganic silicon' rather than 'silicate' in new Standard Names. I
also think it's worth some clarification in the definition to explain
how things can be dissolved in something that many would think of as a
solid.
So that will give us:
moles_of_nitrogen_per_unit_area_in_seabed_sediment
unit: mol/m2
description: moles_of_X_per_unit_area_in_Y describes the amount of X
in a column with unity base area of material/compartment Y. 'Seabed
sediment' means particulate matter bound at the sea floor including
interstitial pore water. Information on the location of the interface
between water column and sediment can be provided via the comment

moles_of_dissolved_inorganic_silicon_per_unit_area_in_seabed_sediment

Great :-) . Then I would like to propose the following two new
standard names:
moles_of_nitrogen_per_unit_area_in_seabed_sediment
unit: mol/m2
description: moles_of_X_per_unit_area_in_Y describes the amount of X
in a column with unity base area of material/compartment Y. 'Sediment'
means particulate matter bound at the sea floor. Information on the
location of the interface between water column and sediment can be

and
moles_of_silicate_expressed_as_silicon_per_unit_area_in_seabed_sediment
unit: mol/m2
description: moles_of_X_per_unit_area_in_Y describes the amount of X
in a column with unity base area of material/compartment Y. 'Sediment'
means particulate matter bound at the sea floor. Information on the
location of the interface between water column and sediment can be

Dear Roy, Dear Jonathan,
Thank you for the feedback. I see that sediment might be ambiguous.
Would "seabed sediment" or "marine seabed sediment" be an acceptable
alternative?
moles_of_nitrogen_per_unit_area_in_seabed_sediment
This would clarify that the sea floor is meant as location of the
sediment. It would also clarify that not bare rock is meant.
Cheers,
Daniel

Thanks Daniel,
Couple of additional thoughts that struck me. Is there possibility
of confusion between seafloor sediment and suspended sediment? What
if the seabed was bare rock? So, might:
moles_of_nitrogen_per_unit_area_in_seabed
be better?
Let’s see if we get any other thoughts on the list.
Cheers, Roy.

Yes
In our current model setup (ecosystem model of the water column) we
have a fairly simple sediment and write out the nitrogen amount per m2.
This name might be appropriate for this purpose:
moles_of_nitrogen_per_unit_area_in_sediment
unit:
mol/m2
description:
moles_of_X_per_unit_area_in_Y describes the amount of X in a column
with unity base area of material/compartment Y. 'Sediment' means
particulate matter bound at the sea floor. Information on the
location of the interface between water column and sediment can be
provided via the comment attribute.

Some thoughts based on my experience with observed sediment
chemistry data. The data may be reported per unit mass of wet
or dry sediment or per unit volume of wet sediment. Also it is
worth making clear that 'sediment' means sediment of all grain
sizes (say a phrase like 'total_sediment') as samples are
frequently sieved prior to analysis.
I'm presuming your coming from a modelling perspective, so I'm
not totally clear about your needs, but would something like
'mole_concentration_of_nitrogen_in_wet_total_sediment' be what
you would be looking for?
Cheers, Roy.

Dear CF Mailing List,
I am looking for standard names to describe the mole
concentration of
nitrogen in the sediment. The CF standard name table does not
contain
any standard names regarding "mole_concentration" in "sediment".
I was
wondering whether another term than "sediment" was used for such
names.
I also tried "mud", "seabed", and "sea_bed". Or do no such standard
names exist at all?
Cheers,
Daniel
