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
