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.


Cheers,
Daniel

Dear Daniel,

ocean.



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.

Subject: [CF-metadata] No standard names for element concentrations in sediment?

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
