Approximately one-quarter of the anthropogenic carbon dioxide released into the atmosphere each year is absorbed by the global oceans, causing measurable declines in surface ocean pH, carbonate ion concentration ([CO32−]), and saturation state of carbonate minerals (Ω). This process, referred to as ocean acidification, represents a major threat to marine ecosystems, in particular marine calcifiers such as oysters, crabs, and corals. Laboratory and field studies have shown that calcification… Expand
Carbon dioxide addition to coral reef waters suppresses net community calcification
TLDR
This estimate provides evidence that near-future reductions in the aragonite saturation state will compromise the ecosystem function of coral reefs, and is the first to be based on a controlled experiment in the natural environment. Expand
Community production modulates coral reef pH and the sensitivity of ecosystem calcification to ocean acidification
Coral reefs are built of calcium carbonate (CaCO3) produced biogenically by a diversity of calcifying plants, animals, and microbes. As the ocean warms and acidifies, there is mounting concern thatExpand
Ocean Acidification and Coral Bleaching
Simultaneous with the increases in global sea surface temperature, increasing atmospheric carbon dioxide (CO2) is driving changes in the chemistry of the oceans—a process known as oceanExpand
The Risk of Ocean Acidification to Ocean Ecosystems
Ocean acidification is a process that refers to major changes to the ocean’s carbonate chemistry, mainly caused by ocean uptake of anthropogenic emissions of carbon dioxide. This process involves aExpand
Living coral tissue slows skeletal dissolution related to ocean acidification
TLDR
It is suggested that areas of the reef with relatively low coral mortality, where living coral cover is high, are likely to be resistant to carbon dioxide-induced reef dissolution, and elevated carbon dioxide impairs net calcification of living corals and may accelerate dissolution of dead corals.

Low and variable ecosystem calcification in a coral reef lagoon under natural acidification
Laboratory-based CO2 experiments and studies of naturally low pH coral reef ecosystems reveal negative impacts of ocean acidification on the calcifying communities that build coral reefs. Conversely,Expand
Interannual stability of organic to inorganic carbon production on a coral atoll
Ocean acidification has the potential to adversely affect marine calcifying organisms, with substantial ocean ecosystem impacts projected over the 21st century. Characterizing the in situ sensitivityExpand
Responses of coral reef community metabolism in flumes to ocean acidification
TLDR
Gnet was depressed under elevated pCO2 over 4 months, although the magnitude of the response varied over time, and underscores the challenges of scaling-up experimental results on the effects of p CO2 from coral reef organisms to coral reef communities. Expand
Emergent constraint on Arctic Ocean acidification in the twenty-first century
TLDR
Greater regional anthropogenic carbon storage and ocean acidification than previously projected is indicated and the probability that large parts of the mesopelagic Arctic Ocean will be undersaturated with respect to calcite by the end of the century is increased. Expand
Shifts in coralline algae, macroalgae, and coral juveniles in the Great Barrier Reef associated with present-day ocean acidification.
TLDR
Data from three independent large-scale reef monitoring programs are used to assess coral reef responses associated with changes in mean aragonite saturation state in the Great Barrier Reef World Heritage Area and suggest a tipping point at 3.5-3.6 for these coral reef health indicators. Expand
