Abstract: The acidification of the surface ocean by anthropogenic CO2 absorbed from the atmosphere is now well-recognised and is considered to have lowered surface ocean pH by 0.1 since the mid-18th century. Further acidification in the future may lead to undersaturation of CaCO3 making growth of calcifying organisms difficult. However, other anthropogenic gases may also alter ocean pH, specifically SOx and NOx and NH3. While the effects of these are negligible on a global scale, we demonstrate using a simple model that in coastal water regions with high shipping density, the potential exists for these gases to make a major contribution to acidification.
