Dear Jonathan,
That's fine for me.

Dear Daniel and Roy
I sent an email yesterday which for some reason disappeared into the void.
Please could I request sea_floor_sediment instead of seabed_sediment? That's
because we already use sea_floor in several standard names, but not sedbed.
Best wishes
Jonathan

Hi Roy,
OK, that's fine. Thanks.

Hi Daniel,
Most of the solids in sediment are silicate minerals, quite often
quartz (silicon dioxide), which would be included in
'moles_of_silicon' So, I suggest:
moles_of_dissolved_inorganic_plus_biogenic_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. 'Dissolved inorganic silicon' means the
sum of all inorganic silicon in solution (including silicic acid
and its first dissociated anion SiO(OH)3-). 'Biogenic silicon' is
any silicon compound, usually the mineral opal, produced by
organisms (e.g. diatom skeletal remains) in solid or colloidal
form.

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

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.

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.

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.

Dear Roy,
I think benthos chemistry is virgin territory for CF - not
really surprising for a standard that started in the
atmosphere before dipping its toes in the ocean.
:-)
I'm presuming your coming from a modelling perspective,
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

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
