sea_water_ph_natural_analogue_reported_on_total_scale  

Definition

  • sea_water_pH_reported_on_total_scale is the measure of acidity of sea water, defined as the negative logarithm of the concentration of dissolved hydrogen ions plus bisulfate ions in a sea water medium; it can be measured or calculated; when measured the scale is defined according to a series of buffers prepared in artificial seawater containing bisulfate. The quantity may be written as pH(total) = -log([H+](free) + [HSO4-]). In ocean biogeochemistry models, a "natural analogue" is used to simulate the effect on a modelled variable of imposing preindustrial atmospheric carbon dioxide concentrations, even when the model as a whole may be subjected to varying forcings.

Note

  • Mapping to be determined
