is there such a thing as ocean acidification, and should we worry about it?
No, the oceans have always been alkaline and will remain so, despite any minor decrease in alkalinity caused by the absorbtion of extra carbon dioxideHaving noted that, an ocean becoming less alkaline is known as ocean acidification, even if that ocean will never turn to acid.
Phys.Org reports on a new paper published late last year in the journal Proceedings of the Royal Society B: Biological Sciences.
Researchers from Northeastern University's Marine Science Center and the University of North Carolina at Chapel Hill have found that moderate ocean acidification and warming can actually enhance the growth rate of one reef-building coral species. Only under extreme acidification and thermal conditions did calcification decline.Science Daily summarises:
New research explains how moderate increases in ocean acidification and temperature can enhance the growth rates of some reef-forming corals. Authors of a new report attribute the coral's positive response to moderately elevated carbon dioxide to the fertilization of photosynthesis within the coral's algal symbionts, which may provide the coral with more energy for calcification even though the seawater is more acidic.The Paper: (link)
