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.
