Seawater carbonate chemistry and Emiliania huxleyi biological processes durin...
The calcifying phytoplankton species, coccolithophores, have their calcified coccoliths around the cells, however, their physiological roles are still unknown. Here, we... -
Seawater carbonate chemistry and processes during experiments with Emiliania ...
The physiological performance of two coccolithophore species,Emiliania huxleyi and Coccolithus braarudii, was investigated during long-term exposure to elevated pCO2 levels.... -
Seawater carbonate chemistry and processes during experiments with phytoplank...
The response of the coccolithophore Emiliania huxleyi to rising CO2 concentrations is well documented for acclimated cultures where cells are exposed to the CO2 treatments for... -

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.... -

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... -
Seawater carbonate chemistry and processes during experiments with Emiliania ...
Precipitation of calcium carbonate by phytoplankton in the photic oceanic layer is an important process regulating the carbon cycling and the exchange of CO2 at the... -

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... -
Seawater carbonate chemistry, growth rate and processes during experiments wi...
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... -
Seawater carbonate chemistry and processes during experiments with Emiliania ...
Ocean acidification in response to rising atmospheric CO2 partial pressures is widely expected to reduce calcification by marine organisms. From the mid-Mesozoic,... -
Seawater carbonate chemistry and biological processes during experiments with...
Increasing atmospheric CO2 concentration affects calcification in most planktonic calcifiers. Both reduced or stimulated calcification under high CO2 have been reported in the... -
Seawater chemistry, nutrients, chlorophyll a, and growth rate of Phaeocystis ...
Phaeocystis globosa (Prymnesiophyceae) is an ecologically dominating phytoplankton species in many areas around the world. It plays an important role in both the global sulfur... -
Seawater carbonate chemistry and photosynthetic response of Emiliania huxleyi...
Changes in calcification of coccolithophores may affect their photosynthetic responses to both, ultraviolet radiation (UVR, 280-400 nm) and temperature. We operated... -
Control of ambient pH on growth and stable isotopes in phytoplanktonic calcif...
The present work examines the relationship between pH-induced changes in growth and stable isotopic composition of coccolith calcite in two coccolithophore species with a... -
Vanishing coccolith vital effects with alleviated carbon limitation
By recreating a range of geologically relevant concentrations of dissolved inorganic carbon (DIC) in the laboratory, we demonstrate that the magnitude of the vital effects in... -
Seawater carbonate chemistry and lipid content, particulate organic carbon/ni...
Coccolithophores are a calcifying unicellular phytoplankton group that are at the base of the marine food web, and their lipid content provides a source of energy to consumers.... -
Solar UV irradiances modulate effects of ocean acidification on the Coccolith...
Emiliania huxleyi, the most abundant coccolithophorid in the oceans, is naturally exposed to solar UV radiation (UVR, 280-400 nm) in addition to photosynthetically active... -
The effect of nitrate and phosphate availability on Emiliania huxleyi(NZEH) p...
Growth and calcification of the marine coccolithophorid Emiliania huxleyi is affected by ocean acidification and macronutrients limitation and its response varies between... -
