Dear all,

We would like to suggest the addition of two new standard_names for
ocean biogeochemistry:

- *mass_concentration_of_chlorophyll_a_fluorescence_in_sea_water*
unit: kg m-3
definition:
Mass concentration means mass per unit volume and is used in the
construction mass_concentration_of_X_in_Y, where X is a material
constituent of Y. A chemical species denoted by X may be described by a
single term such as 'nitrogen' or a phrase such as
'nox_expressed_as_nitrogen'. Chloropyll fluorescence is a proxy for
Chlorophyll concentration measuring re-emitted light from light
absorption. Chlorophylls are the green pigments found in most plants,
algae and cyanobacteria; their presence is essential for photosynthesis
to take place. There are several different forms of chlorophyll that
occur naturally. All contain a chlorin ring (chemical formula C20H16N4)
which gives the green pigment and a side chain whose structure varies.
The naturally occurring forms of chlorophyll contain between 35 and 55
carbon atoms.Chlorophyll fluorescence is mainly emitted from the
Chlorophyll a pigment.

I believe there are no standard_names yet for fluorescence. The
definition was built from the
mass_concentration_of_chlorophyll_a_in_sea_water definition.

- *sea_water_alkalinity_per_unit_mass*
unit: mol kg-1
definition:
sea_water_alkalinity_per_unit_mass is the total alkalinity (including
carbonate, nitrogen, silicate, and borate components).

A standard name already exists for alkalinity expressed as mol/m3,
|sea_water_alkalinity_expressed_as_mole_equivalent
<javascript:void(0)>||,||||but none exist for mol/kg.|

Best regards,

Elodie
