Uptake of half of the fossil fuel CO2 into the ocean causes gradual seawater acidification. This has been shown to slow down calcification of major calcifying groups, such as corals, foraminifera, and coccolithophores. Here we show that two of the most productive marine calcifying species, the coccolithophores Coccolithus pelagicus and Calcidiscus leptoporus, do not follow the CO2‐related calcification response previously found. In batch culture experiments, particulate inorganic carbon (PIC… 

Figures and Tables from this paper

A coastal coccolithophore maintains pH homeostasis and switches carbon sources in response to ocean acidification

Novel chemical constraints are reported on the response of the widespread coccolithophore species Ochrosphaera neapolitana to changing-CO2 conditions that maintain its calcification site pH and utilizes more CO2 compared to HCO3− to support its growth under high- CO2 conditions.

Coccolithophore calcification is independent of carbonate chemistry in the tropical ocean

Short‐term experiments indicate that seawater acidification can cause a decrease in the rate of calcification by coccolithophores, but the relationship between carbonate chemistry and coccolithophore

A comparison of species specific sensitivities to changing light and carbonate chemistry in calcifying marine phytoplankton

An analytical equation is fit, accounting for simultaneous changes in CO2 and light intensity, to rates of photosynthesis, calcification and growth in Scyphosphaera apsteinii to suggest that this is driven by a drop in maximum rates and, in G. oceanica, increased substrate uptake efficiency.

Competitive fitness of a predominant pelagic calcifier impaired by ocean acidification

It is concluded that ocean acidification can lower calcifying phytoplankton productivity, potentially creating a positive feedback to the climate system.

Decrease in coccolithophore calcification and CO2 since the middle Miocene

Degree of calcification was highest in the low-pH, high-CO2 Miocene ocean, but decreased significantly between 6 and 4 Myr ago, and it is proposed that decreasing CO2 partly drove the observed trend via reduced cellular bicarbonate allocation to calcification.

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.

Constraints on coccolithophores under ocean acidification from boron and carbon geochemical approaches

Ocean acidification (OA) appears to have diverse impacts on calcareous coccolithophores, but the cellular processes underlying these responses are not well understood. Here we use stable boron and

Perturbing phytoplankton : a tale of isotopic fractionation in two coccolithophore species

No two species of coccolithophore appear to respond to perturbations of carbonate chemistry in the same way. Here, we show that the degree of malformation, growth rate and stable isotopic composition

Inter- and intra-specific responses of coccolithophores to CO 2 -induced ocean acidification

It is determined that the responses of coccolithophores to ocean acidification are inter- and intra-specific, and this variation may cause changes to biodiversity and other ecosystem processes in the future ocean.

Algal constraints on the cenozoic history of atmospheric CO2




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.

Response of primary production and calcification to changes of pCO2 during experimental blooms of the coccolithophorid Emiliania huxleyi

Primary production and calcification in response to different partial pressures of CO2 (PCO2) (“glacial,” “present,” and “year 2100” atmospheric CO2 concentrations) were investigated during a

Reassessing foraminiferal stable isotope geochemistry: Impact of the oceanic carbonate system (experimental results)

Laboratory experiments with living planktic foraminifers show that the δ13C and δ18O values of shell calcite decrease with increasing sea water pH and/or carbonate ion concentration. The effect has

Coccolithophores first became significant participants in the carbonate cycle in the Jurassic, but throughout the Jurassic they were largely restricted to shelf and epeiric sea environments. They

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.

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

The Source of Ions for Biomineralization in Foraminifera and Their Implications for Paleoceanographic Proxies

The global carbon cycle is strongly perturbed by fossil fuel burning leading to atmospheric CO2 increase. Climatic warming followed by polar ice melting and global sea level rise are predicted due to

Calcification in coccolithophores: A cellular perspective

Transport processes in delivery of substrates for calcification will improve the ability to interpret isotopic fractionation in the fossil record that is increasingly being used as a proxy for past climatic conditions and contribute to the goal of understanding of how cellular functions contribute to processes at ecosystem and global levels.
