The formation of calcareous skeletons by marine planktonic organisms and their subsequent sinking to depth generates a continuous rain of calcium carbonate to the deep ocean and underlying sediments. This is important in regulating marine carbon cycling and ocean–atmosphere CO2 exchange. The present rise in atmospheric CO2 levels causes significant changes in surface ocean pH and carbonate chemistry. Such changes have been shown to slow down calcification in corals and coralline macroalgae… 
Latitudinal Variation of Planktonic Foraminifera Shell Masses During Termination I
The oceans’ surface layer holds large amounts of dissolved inorganic carbon that is exchanged rapidly with the atmosphere. Carbon enters the ocean mainly through the dissolution of atmospheric carbon
The role of nutricline depth in regulating the ocean carbon cycle
Analysis of phytoplankton community composition in the Atlantic Ocean shows that the distribution of diatoms and coccolithophorids is correlated with the nutricline depth, a proxy of nutrient supply to the upper mixed layer of the ocean, and provides a mechanistic basis for understanding the connection between upper ocean dynamics, the calcium carbonate-to-organic C production ratio and atmospheric pCO2 variations on time scales ranging from seasonal cycles to geological transitions.
Sensitivity of coccolithophores to carbonate chemistry and ocean acidification
The analyses revealed that differentially calcified species and morphotypes are distributed in the ocean according to carbonate chemistry, and the discovery of a heavily calcified Emiliania huxleyi morphotype in modern waters with low pH highlights the complexity of assemblage-level responses to environmental forcing factors.
Effects of CO2 Enrichment on Marine Phytoplankton
Rising atmospheric CO2 and deliberate CO2 sequestration in the ocean change seawater carbonate chemistry in a similar way, lowering seawater pH, carbonate ion concentration and carbonate saturation
Phytoplankton mineralization in the tropical and subtropical Atlantic Ocean
Organic carbon fluxes to the deep ocean may be enhanced by association with ballast mineral material such as calcite and opal. We made simultaneous measurements of the upper ocean production of
Ocean Acidification Reduces Growth and Calcification in a Marine Dinoflagellate
A substantial reduction in growth rate, calcification and cyst stability of T. heimii under elevated pCO2 is observed and transcriptomic analyses reveal CO2 sensitive regulation of many genes, particularly those being associated to inorganic carbon acquisition and calcification.
Oceanography: Forecasting the rain ratio
By analysing both contemporary surface water samples and fossil sediment cores, Beaufort et al. show that an increase in dissolved CO2 causes a decrease in calcification rates, and that the abundance of heavily calcified coccolithophore morphotypes is dependent on carbonate chemistry.
Coccolithophore Growth and Calcification in an Acidified Ocean: Insights From Community Earth System Model Simulations
Anthropogenic CO2 emissions are inundating the upper ocean, acidifying the water, and altering the habitat for marine phytoplankton. These changes are thought to be particularly influential for
Phytoplankton Calcification in a High-CO2 World
Ocean acidification in response to rising atmospheric CO2 partial pressures is widely expected to reduce calcification by marine organisms. From the mid-Mesozoic, coccolithophores have been major
Negative effects of ocean acidification on calcification vary within the coccolithophore genus Calcidiscus
It is suggested that calcium carbonate production relative to organic carbon production by Calcidiscus coccolithophores may decrease in future oceans and that Calcodiscus distributions may shift if more resilient strains and species become dominant in assemblages.


Effect of calcium carbonate saturation state on the calcification rate of an experimental coral reef
The concentration of CO2 in the atmosphere is projected to reach twice the preindustrial level by the middle of the 21st century. This increase will reduce the concentration of CO32− of the surface
Production and accumulation of calcium carbonate in the ocean: Budget of a nonsteady state
Present-day production of CaCO3 in tne world ocean is calculated to be about 5 billion tons (bt) per year, of which about 3 bt accumulate in sediments; the other 40% is dissolved. Nearly half of the
Direct effects of CO2 concentration on growth and isotopic composition of marine plankton
The assessment of direct effects of anthropogenic CO 2 increase on the marine biota has received relatively little attention compared to the intense research on CO 2 -related responses of the
Significance of ocean carbonate budgets for the global carbon cycle
Changes in the trace gas composition of the atmosphere over glacial–interglacial cycles are linked to changes in the oceanic carbon cycle. This paper examines the role of biologically driven fluxes
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:
Marine biota effects on the compositional structure of the world oceans
The vertical structure of total carbon, alkalinity, nutrients, and dissolved oxygen in the world oceans is examined with a one-dimensional equatorial ocean/polar ocean box model.
Impact of a coccolithophorid bloom on dissolved carbon dioxide in sea water enclosures in a Norwegian fjord
Abstract During an experiment conducted using four, 11 m3 mesocosms situated in a small Norwegian fjord, the partial pressure of carbon dioxide (PCO2) and dissolved oxygen were determined in each
