Parameter: chlorophyll a

Short Description: chlorophyll a
Short Name: chl_a
Official Name: chlorophyll a
Units: various
External Identifier: skos:closeMatch: http://vocab.nerc.ac.uk/collection/P01/current/CPHLHPP1/

Description

Total chlorophyll a pigment. See dataset for units of measurement; often reported in: milligrams per cubic meter (mg/m3); micrograms/liter (ug/L); nanograms/liter (ng/L).

CAUTION Within JGOFS MERGED water column products: this parameter is derived from HPLC methodology and the units are nanograms/liter; however; this parameter name is also used for a variety of water and nonwater column sampling; derived via the fluorometric method; units will also vary.
