The atmospheric partial pressure of carbon dioxide (pCO2) will almost certainly be double that of pre-industrial levels by 2100 and will be considerably higher than at any time during the past few million years. The oceans are a principal sink for anthropogenic CO2 where it is estimated to have caused a 30% increase in the concentration of H+ in ocean surface waters since the early 1900s and may lead to a drop in seawater pH of up to 0.5 units by 2100 (refs 2, 3). Our understanding of how…

TLDR
If solar radiation management were to be the main policy response to counteract global warming, ocean acidification would continue to be driven by increases in atmospheric CO2, although with additional temperature-related effects on CO2 and CaCO3 solubility and terrestrial carbon sequestration.
Volcanic CO2 seep geochemistry and use in understanding ocean acidification
Ocean acidification is one of the most dramatic effects of the massive atmospheric release of anthropogenic carbon dioxide (CO 2 ) that has occurred since the Industrial Revolution, although its

Acidification of Lower St. Lawrence Estuary Bottom Waters
Accumulation of metabolic CO2 can acidify marine waters above and beyond the ongoing acidification of the ocean by anthropogenic CO2. The impact of respiration on carbonate chemistry and pH is most
Adverse Effect of Ocean Acidification on Marine Organisms
Ocean acidification (OA) is a process induced by a change in the chemistry of carbonate. In normal situations carbon dioxide (CO2) is produced by either photosynthesis and respiration and in long
The effects of acidification and warming on marine calcifying biota
TLDR
Results suggest that seasonal variability in environmental conditions will greatly impact the response of coralline algae to elevated temperature and pCO2, and supports the hypothesis that dissolution may in fact be the primary threat to marine calcifiers, as opposed to impaired calcification.
Clues from Current High CO2 Environments on the Effects of Ocean Acidification on CaCO3 Preservation
Acidification of surface seawater owing to anthropogenic activities has raised serious concerns on its consequences for marine calcifying organisms and ecosystems. To acquire knowledge concerning the
Ocean acidification: the other CO2 problem.
TLDR
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.
The effects of elevated CO2 and ocean acidification on the production of marine biogenic trace gases
The human-induced increases in atmospheric carbon dioxide since the beginning of the industrial revolution have led to increasing oceanic carbon uptake and changes in seawater carbonate chemistry,

Enhanced biological carbon consumption in a high CO2 ocean
TLDR
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.
Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms
TLDR
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.
Impact of Anthropogenic CO2 on the CaCO3 System in the Oceans
TLDR
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.
Atmospheric carbon dioxide concentrations over the past 60 million years
TLDR
The boron-isotope ratios of ancient planktonic foraminifer shells are used to estimate the pH of surface-layer sea water throughout the past 60 million years, which can be used to reconstruct atmospheric CO2 concentrations.
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
Coral Reefs Under Rapid Climate Change and Ocean Acidification
TLDR
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.

Elevated CO2 enhances nitrogen fixation and growth in the marine cyanobacterium Trichodesmium
TLDR
In oceanic regions, where light and nutrients such as P and Fe are not limiting, it is expected the projected concentrations of CO₂ to increase N fixation and growth of Trichodesmium, thereby enhancing inputs of new N and increasing primary productivity in the oceans.
