To evaluate the influence of episodic extreme ocean acidification events in coastal regions, we deployed eight pelagic mesocosms for 53 days in Raunefjord, Norway, and enclosed... -
Results of a 24-hour laboratory experiment sampling cell concentrations, part...
Cell division of the coccolithophore Emiliania huxleyi and other phytoplankton typically becomes entrained to diel light/dark cycles under laboratory conditions, with division... -
Seawater carbonate chemistry and phytoplankton stoichiometry, production and ...
There is a growing consensus that the ongoing increase in atmospheric CO2 level will lead to a variety of effects on marine phytoplankton and ecosystems. However, the effects of... -
Influence of temperature and CO2 on the strontium and magnesium composition o...
Marine calcareous sediments provide a fundamental basis for palaeoceanographic studies aiming to reconstruct past oceanic conditions and understand key biogeochemical element... -
Long-term dynamics of adaptive evolution in a globally important coccolithoph...
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne et al, 2014) was used to compute a complete and consistent set of... -
Seawater carbonate chemistry and growth rate, cellular POC, PON, PIC contents
Coccolithophores are important oceanic primary producers not only in terms of photosynthesis but also because they produce calcite plates called coccoliths. Ongoing ocean... -
H+-driven increase in CO2 uptake and decrease in HCO3- uptake explain coccoli...
Recent ocean acidification (OA) studies revealed that seawater [H+] rather than [CO2] or [ inline image] regulate short-term responses in carbon fluxes of Emiliania huxleyi.... -
The modulating effect of light intensity on the response of the coccolithopho...
Global change leads to a multitude of simultaneous modifications in the marine realm among which shoaling of the upper mixed layer, leading to enhanced surface layer light... -
Differing responses of three Southern Ocean Emiliania huxleyi ecotypes to cha...
The invasion of anthropogenic carbon dioxide into the surface ocean is altering seawater carbonate speciation, a process commonly called ocean acidification. The high latitude... -
No detectable effect of CO2 on elemental stoichiometry of Emiliania huxleyi i...
Effects of CO2 concentration on elemental composition of the coccolithophore Emiliania huxleyi were studied in phosphorus-limited, continuous cultures that were acclimated to... -
Adaptive evolution of a key phytoplankton species to ocean acidification, sup...
Ocean acidification, the drop in seawater pH associated with the ongoing enrichment of marine waters with carbon dioxide from fossil fuel burning, may seriously impair marine... -
Experiment: Dissecting the impact of CO2 and pH on the mechanisms of photosyn...
Coccolithophores are important calcifying phytoplankton predicted to be impacted by changes in ocean carbonate chemistry caused by the absorption of anthropogenic CO2. However,... -
Seawater carbonate chemistry and its effects on properties and sinking veloci...
Coccolithophores play an important role in organic matter export due to their production of the mineral calcite that can act as ballast. Recent studies indicated that... -
Seawater carbonate chemistry and biological processes of coccolithophore (Gep...
All species of coccolithophore appear to respond to perturbations of carbonate chemistry in a different way. Here, we show that the degree of malformation, growth rate and... -
Seawater carbonate chemistry, pigments and biological processes during experi...
Previous studies have shown that increasing atmospheric CO2 concentrations affect calcification in some planktonic and macroalgal calcifiers due to the changed carbonate... -
Seawater carbonate chemistry and biological processes during experiments with...
Four strains of the coccolithophore E. huxleyi (RCC1212, RCC1216, RCC1238, RCC1256) were grown in dilute batch culture at four CO2 levels ranging from ~200 µatm to ~1200 µatm.... -
Fit procedure with experimental data
Maximum measured calcite to organic carbon (PIC:POC) ratio and maximum population mean coccosphere diameter of the four coccolithophore investigated here. (Values were extracted... -
Culture experiments with Coccolithus pelagicus ssp. braarudii
Carbonate chemistry and physiological growth data of experiments with C. pelagicus. Mean TA and DIC were calculated as average of initial and final values. pH, pCO2, HCO3-,... -
Seawater carbonate chemistry and calcification of an estuarine coccolithophore
Ocean acidification has the capacity to impact future coccolithophore growth, photosynthesis, and calcification, but experimental culture work with coccolithophores has produced... -
Seawater carbonate chemistry and growth rate, particulate organic (POC) and i...
Continuous accumulation of fossil CO2 in the atmosphere and increasingly dissolved CO2 in seawater leads to ocean acidification (OA), which is known to affect phytoplankton...
