net_primary_mole_productivity_of_biomass_expressed_as_carbon_by_diazotrophs
completeCreated: Dec. 5, 2018
Proposer: Alison Pamment
Proposed Date: 2018-12-05
Simplify definition of 'phytoplankton' for consistency with names introduced for CMIP6. Correct several typos in definition (missing/extra white-space, inconsistent use of single and double quotes, etc).

"Production of carbon" means the production of biomass expressed as the mass of carbon which it contains. Net primary production is the excess of gross primary production (rate of synthesis of biomass from inorganic precursors) by autotrophs ("producers"), for example, photosynthesis in plants or phytoplankton, over the rate at which the autotrophs themselves respire some of this biomass. "Productivity" means production per unit area. In ocean modelling, diazotrophs are phytoplankton of the phylum cyanobacteria distinct from other phytoplankton groups in their ability to fix nitrogen gas in addition to nitrate and ammonium. Phytoplankton are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis. The phrase "expressed_as" is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A.
