What Is Ocean Acidification & Why Does It Matter?
For other marine life, however, there is no escape from ocean acidification. "Ocean acidification has effects, in the end, for our food chain. We see it in pteropods—tiny marine snails are an important source of food for juvenile Pacific salmon. They are growing thinner shells, and the shells malform under acidified conditions. We see it in ...
What causes ocean acidification?
In the past, ocean acidification occurred naturally but over much longer periods of time. It is occurring faster now than in the last 20 million years.

CO2 and Ocean Acidification
CO 2 concentrations drive rising temperatures and acidification. The rising concentration of carbon dioxide in the atmosphere is driving up ocean surface temperatures and causing ocean acidification. Although warming and acidification are different phenomena, they interact to the detriment of marine ecosystems. These changes to the ocean aren''t occurring at …
Ocean acidification: A wake-up call in our waters
Ocean acidification, driven by an overload of CO2 in our seas, is literally causing a sea change, threatening the chemical balance of ocean and coastal waters worldwide. Ocean acidification is a severe threat to shellfish, corals and other marine life because corrosive water can destroy their protective shells and skeletons, putting foo

The state of ocean acidification
By Fiona Brown, Chris Gerbing 25 November 2020 6 min read. As reported in the CSIRO and Bureau of Meteorology''s latest State of the Climate report, oceans around Australia are acidifying 10 times faster than at any point in the last 300 million years. When coupled with ocean warming and deoxygenation, this is putting considerable pressure on our …

Impacts of ocean acidification on marine shelled molluscs
Over the next century, elevated quantities of atmospheric CO2 are expected to penetrate into the oceans, causing a reduction in pH (−0.3/−0.4 pH unit in the surface ocean) and in the concentration of carbonate ions (so-called ocean acidification). Of growing concern are the impacts that this will have on marine and estuarine organisms and ecosystems. Marine shelled …
