Impacts of ocean acidification on marine organisms: quantifying sensitivities and interaction with warming
The most comprehensive meta-analysis to date by synthesizing the results of 228 studies examining biological responses to ocean acidification reveals decreased survival, calcification, growth, development and abundance in response to acidification, and suggests that other factors, such as nutritional status or source population, could cause substantial variation in organisms' responses.
Guide to best practices for ocean acidification research and data reporting
Ocean acidiﬁcation is an undisputed fact. The ocean presently takes up one-fourth of the carbon CO2 emitted to the atmosphere from human activities. As this CO2 dissolves in the surface ocean, it…
Contrasting futures for ocean and society from different anthropogenic CO2 emissions scenarios
The physics, chemistry, and ecology of the oceans might be affected based on two CO2 emission trajectories: one business as usual and one with aggressive reductions, consistent with the Copenhagen Accord of keeping mean global temperature increase below 2°C in the 21st century.
CARBON AND CARBONATE METABOLISM IN COASTAL AQUATIC ECOSYSTEMS
The coastal zone is where land, ocean, and atmosphere interact. It exhibits a wide diversity of geomorphological types and ecosystems, each one displaying great variability in terms of physical and…
Photosynthesis and Calcification at Cellular, Organismal and Community Levels in Coral Reefs: A Review on Interactions and Control by Carbonate Chemistry
SYNOPSIS. Photosynthesis and calcification in zooxanthellate scleractinian corals and coral reefs are reviewed at several scales: cellular (pathways and transport mechanisms of inorganic carbon and…
Marine calcification as a source of carbon dioxide : positive feedback of increasing atmospheric CO2
Calcification is a well-recognized source of CO2 to the surrounding water and thus a potential source of atmospheric CO2 due to chemical equilibria involving the CO2 species. The released CO2:…

It is shown here that CO2 partial pressure (pCO2) and temperature significantly interact on coral physiology, and warrants a re-evaluation of the projected decrease of marine calcification by the year 2100.

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 potentially…

Impacts of ocean acidification on marine shelled molluscs
While fertilization may remain unaffected by elevated pCO2, embryonic and larval development will be highly sensitive with important reductions in size and decreased survival of larvae, increases in the number of abnormal larvae and an increase in the developmental time.
