mass_concentration_of_diatoms_expressed_as_nitrogen_in_sea_water

complete
Created: 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).

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'. 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. Diatoms are single-celled phytoplankton with an external skeleton made of silica. Phytoplankton are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis.
