This new concept of anthropogenic impacts on seawater pH formulated here accommodates the broad range of mechanisms involved in the anthropogenic forcing of pH in coastal ecosystems, including changes in land use, nutrient inputs, ecosystem structure and net metabolism, and emissions of gases to the atmosphere affecting the carbon system and associated pH. The new paradigm is applicable across marine systems, from open - ocean and ocean - dominated coastal systems, where OA by anthropogenic CO2 is the dominant mechanism of anthropogenic impacts on marine pH, to coastal ecosystems where a range of natural and anthropogenic processes may operate to affect pH.

Natural gradients in pH exists across a distance of < 100 m from these volcanic CO2 vents, where the pH increases to normal seawater values of 7.97 — 8.14 (Hall - Spencer et al. 2008; Johnson et al. 2013; Fabricius et al. 2011).
