Rising atmospheric carbon dioxide (CO2), primarily from human fossil fuel combustion, reduces ocean pH and causes wholesale shifts in seawater carbonate chemistry. The process of ocean acidification is well documented in field data, and the rate will accelerate over this century unless future CO2 emissions are curbed dramatically. Acidification alters seawater chemical speciation and biogeochemical cycles of many elements and compounds. One well-known effect is the lowering of calcium carbonate… 
Global declines in oceanic nitrification rates as a consequence of ocean acidification
It is suggested that ocean acidification could reduce nitrification rates by 3–44% within the next few decades, affecting oceanic nitrous oxide production, reducing supplies of oxidized nitrogen in the upper layers of the ocean, and fundamentally altering nitrogen cycling in the sea.
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
How ocean acidification can benefit calcifiers
Detecting anthropogenic carbon dioxide uptake and ocean acidification in the North Atlantic Ocean
Abstract. Fossil fuel use, cement manufacture and land-use changes are the primary sources of anthropogenic carbon dioxide (CO2) to the atmosphere, with the ocean absorbing approximately 30% (Sabine
Ocean Acidification and Related Indicators
Ocean acidification is one of the main consequences of global climate change. It is caused by the increasing input of atmospheric CO2 in the world ocean, which in turn is affecting the marine
Millennial Scale Impacts of Marine Biogenic Calcification Changes on Ocean Carbon Cycling
Ocean acidification resulting from increasing anthropogenic carbon dioxide (CO2) emissions are likely to impact calcification rates in pelagic organisms which may, in turn, lead to changes in the
Biogeosciences Detecting anthropogenic carbon dioxide uptake and ocean acidification in the North Atlantic Ocean
Fossil fuel use, cement manufacture and land-use changes are the primary sources of anthropogenic carbon dioxide (CO2) to the atmosphere, with the ocean absorbing approximately 30 % (Sabine et al.,
Nonuniform ocean acidification and attenuation of the ocean carbon sink
Surface ocean carbon chemistry is changing rapidly. Partial pressures of carbon dioxide gas (pCO2) are rising, pH levels are declining, and the ocean's buffer capacity is eroding. Regional
The Impacts of Ocean Acidification on Marine Ecosystems and Reliant Human Communities
Rising atmospheric carbon dioxide (CO2) levels, from fossil fuel combustion and deforestation, along with agriculture and land-use practices are causing wholesale increases in seawater CO2and
Will ocean acidification affect marine microbes?
An appropriate null hypothesis may be, until evidence is obtained to the contrary, that major biogeochemical processes in the oceans other than calcification will not be fundamentally different under future higher CO2/lower pH conditions.


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.
Marine calcifiers exhibit mixed responses to CO2-induced ocean acidification
The results suggest that the impact of elevated atmospheric p CO2 on marine calcification is more varied than previously thought.

The risk of irreversible ecosystem changes due to ocean acidification should enlighten the ongoing CO2 emissions debate and make it clear that the human dependence on fossil fuels must end quickly.
Volcanic carbon dioxide vents show ecosystem effects of ocean acidification
The species populating the vent sites comprise a suite of organisms that are resilient to naturally high concentrations of pCO2 and indicate that ocean acidification may benefit highly invasive non-native algal species.
Enhanced biological carbon consumption in a high CO2 ocean
It is shown that dissolved inorganic carbon consumption of a natural plankton community maintained in mesocosm enclosures at initial CO2 partial pressures increases with rising CO2, and the observed responses have implications for a variety of marine biological and biogeochemical processes, and underscore the importance of biologically driven feedbacks in the ocean to global change.
Imminent ocean acidification in the Arctic projected with the NCAR global coupled carbon cycle-climate model
Abstract. Ocean acidification from the uptake of anthropogenic carbon is simulated for the industrial period and IPCC SRES emission scenarios A2 and B1 with a global coupled carbon cycle-climate
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

Impact of Anthropogenic CO2 on the CaCO3 System in the Oceans
The in situ CaCO3 dissolution rates for the global oceans from total alkalinity and chlorofluorocarbon data are estimated, and the future impacts of anthropogenic CO2 on Ca CO3 shell–forming species are discussed.
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.
