Definition of Ocean acidification:
The process whereby atmospheric carbon dioxide dissolves in seawater producing carbonic acid, which subsequently lowers pH of surrounding seawater; widely thought to be happening on a global scale.
This is the common definition for Ocean acidification, other definitions can be discussed in the article


Other processes also contribute to acidification, especially in eutrophic coastal waters: decomposition of organic material, nitrification in surface water (promoted by sewage discharge) and oxidation processes in sediments[1].
