| Definition | 'Mole concentration' means number of moles per unit volume, also called "molarity", and is used in the construction mole_concentration_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. 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. The specification of a physical process by the phrase due_to_process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. "Net primary production" is the excess of gross primary production of organic carbon (the rate of synthesis of biomass from inorganic precursors) by autotrophs ("producers"), for example, photosynthesis in phytoplankton, over the rate at which the autotrophs themselves respire some of this biomass. 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. "tendency_of_X" means derivative of X with respect to time. | |
