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
provided via the comment attribute.
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
provided via the comment attribute.
Cheers,
Daniel

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
