Parameter: chl_a_ul

Master parameters information
Short Name:
 chl_a
Short Description:
 chlorophyll a
Official Name:
 chlorophyll a
No Data Value:
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.
