Record Title : Gross Primary Productivity of Biomass Expressed As 13C
CF Standard Name : gross_primary_productivity_of_biomass_expressed_as_13C
Record Description : "Production of carbon" means the production of biomass expressed as the mass of carbon which it contains. Gross primary production is the rate of synthesis of biomass from inorganic precursors by autotrophs ("producers"), for example, photosynthesis in plants or phytoplankton. The producers also respire some of this biomass and the difference is "net_primary_production". "Productivity" means production per unit area. 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. "C" means the element carbon and "13C" is the stable isotope "carbon-13", having six protons and seven neutrons.
