Hi Daniel,
That works for me. Cheers, Roy. I am retiring on 31/05/2018 but will continue to be active through an Emeritus Fellowship using this e-mail address. ________________________________ From: CF-metadata <cf-metadata-boun...@cgd.ucar.edu> on behalf of Daniel Neumann <daniel.neum...@io-warnemuende.de> Sent: 17 May 2018 10:41 To: CF Metadata Mail List Subject: Re: [CF-metadata] No standard names for element concentrations in sediment? 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 On 16.05.2018 11:42, Lowry, Roy K. wrote: 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.

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?

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?
