Ocean acidification is rapidly changing the carbonate system of the world oceans. Past mass extinction events have been linked to ocean acidification, and the current rate of change in seawater chemistry is unprecedented. Evidence suggests that these changes will have significant consequences for marine taxa, particularly those that build skeletons, shells, and tests of biogenic calcium carbonate. Potential changes in species distributions and abundances could propagate through multiple trophic… 
A review of comprehensive effect of ocean acidification on marine fishes
Increasing anthropogenic atmospheric CO2 is not only increasing global temperature but also rapidly acidifying seawater through the formation of carbonic acid.This results in another serious
Ocean acidification: the other CO2 problem.
The potential for marine organisms to adapt to increasing CO2 and broader implications for ocean ecosystems are not well known; both are high priorities for future research.
Linking seasonal changes in benthic community structure to seawater chemistry
Ocean acidification (OA) resulting from rising atmospheric CO2 represents a potential threat to marine calcifiers and the ecosystems they inhabit. Numerous studies suggest that decreases in net
Ocean Acidification of the North Pacific Ocean
The addition of fossil fuel carbon dioxide to the atmosphere is rapidly changing seawater chemistry and the calcium carbonate saturation state of the world’s oceans as a result of the acidifying
Feedbacks and responses of coral calcification on the Bermuda reef system to seasonal changes in biological processes and ocean acidification
Abstract. Despite the potential impact of ocean acidification on ecosystems such as coral reefs, surprisingly, there is very limited field data on the relationships between calcification and seawater
MCCIP Ecosystem Linkages Report Card 2009 CO2 and ocean acidification
Evidence from experiments and observations indicate that ocean acidification is a serious threat to many marine organisms which may have implications to the food webs and ecosystems but these are
Predicting the Response of Molluscs to the Impact of Ocean Acidification
Even sub lethal impacts on molluscs due to climate changed oceans will have serious consequences for global protein sources and marine ecosystems.
Impacts of Climate Change on Marine Organisms and Ecosystems
Ocean Acidification: Comparative Impacts on the  Photophysiology of a Temperate Symbiotic Sea Anemone and a Tropical Coral
Assessing the impacts of acidification on the photophysiology and health of the tropical coral Stylophora pistillata and its isolated dinoflagellate symbionts ('zooxanthellae'), and the temperate sea anemone Anthopleura aureoradiata found the increased levels of aqueous CO2 stimulated photosynthesis function and hence mitigated for the effects of lowered pH.
Ocean Acidification and Coral Reefs: An Emerging Big Picture
This article summarises the sometimes controversial contributions made by the different sciences to predict the path of ocean acidification impacts on the diversity of coral reefs during the present


Decreased abundance of crustose coralline algae due to ocean acidification
Increasing levels of atmospheric carbon dioxide leads to ocean acidification, causing significant reductions in the growth of crustose coralline algae. Owing to anthropogenic emissions, atmospheric
Impacts of ocean acidification on marine fauna and ecosystem processes

Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms
13 models of the ocean–carbon cycle are used to assess calcium carbonate saturation under the IS92a ‘business-as-usual’ scenario for future emissions of anthropogenic carbon dioxide and indicate that conditions detrimental to high-latitude ecosystems could develop within decades, not centuries as suggested previously.
Corals in deep-water: will the unseen hand of ocean acidification destroy cold-water ecosystems?
Scleractinian cold-water corals, sometimes referred to as deep-water or deep-sea corals, form perhaps the most vulnerable marine ecosystems to the human dependence on burning fossil fuels (Guinotte
Reduced calcification of marine plankton in response to increased atmospheric CO2
It is suggested that the progressive increase in atmospheric CO2 concentrations may slow down the production of calcium carbonate in the surface ocean, as the process of calcification releases CO2 to the atmosphere.
Coral Reefs Under Rapid Climate Change and Ocean Acidification
As the International Year of the Reef 2008 begins, scaled-up management intervention and decisive action on global emissions are required if the loss of coral-dominated ecosystems is to be avoided.
Effect of seawater carbonate concentration on foraminiferal carbon and oxygen isotopes
Stable oxygen and carbon isotope measurements on biogenic calcite and aragonite have become standard tools for reconstructing past oceanographic and climatic change. In aquatic organisms, 18O/16O
Oceanography: Anthropogenic carbon and ocean pH
It is found that oceanic absorption of CO2 from fossil fuels may result in larger pH changes over the next several centuries than any inferred from the geological record of the past 300 million years.
Reefs of the Deep: The Biology and Geology of Cold-Water Coral Ecosystems
Advances reviewed here include the use of corals as paleoclimatic archives and their biogeological functioning, biodiversity, and biogeography, and the impacts of deep-water trawling and effects of ocean acidification.
Impact of elevated CO 2 on shellfish calcification
[1] Ocean acidification resulting from human emissions of carbon dioxide has already lowered and will further lower surface ocean pH. The consequent decrease in calcium carbonate saturation
