The surface called "surface" means the lower boundary of the atmosphere. sea_water_pH_reported_on_total_scale is the measure of acidity of sea water, defined as the negative logarithm of the activity 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-]). The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase.

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.
