Preferred term

mass_concentration_of_diazotrophic_phytoplankton_expressed_as_carbon_in_sea_water  

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 or biological group 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. Phytoplankton are algae that grow where there is sufficient light to support photosynthesis. Diazotrophic phytoplankton are phytoplankton (predominantly from Phylum Cyanobacteria) that are able to fix molecular nitrogen (gas or solute) in addition to nitrate and ammonium.
