Seawater carbonate chemistry and elemental composition of a southern hemisphe...
A series of semi-continuous incubation experiments were conducted with the coccolithophore Emiliania huxleyi strain NIWA1108 (Southern Ocean isolate) to examine the effects of... -
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.... -
Spring phytoplankton communities of the Labrador Sea (2005-2014): pigment sig...
The Labrador Sea is an ideal region to study the biogeographical, physiological and biogeochemical implications of phytoplankton communities due to sharp transitions of distinct... -
Ocean warming modulates the effects of acidification on Emiliania huxleyi cal...
Ongoing ocean warming and acidification are tied to the rapid accumulation of human-induced carbon dioxide (CO2) in the atmosphere and subsequent uptake of heat and CO2 by the... -
Physiological responses of coastal and oceanic diatoms to diurnal fluctuation...
Diel and seasonal fluctuations in seawater carbonate chemistry are common in coastal waters, while in the open-ocean carbonate chemistry is much less variable. In both of these... -
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... -

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... -
Reduced resilience of a globally distributed coccolithophore to ocean acidifi...
Ocean acidification (OA), induced by rapid anthropogenic CO2 rise and its dissolution in seawater, is known to have consequences for marine organisms. However, knowledge on the... -
Temperature affects the morphology and calcification of Emiliania huxleyi str...
The global warming debate has sparked an unprecedented interest in temperature effects on coccolithophores. The calcification response to temperature changes reported in the... -
Effects of high CO2 levels on the ecophysiology of the diatom Thalassiosira w...
Iron availability in seawater, namely the concentration of dissolved inorganic iron ([Fe']), is affected by changes in pH. Such changes in the availability of iron should be... -
Phytoplankton calcification as an effective mechanism to alleviate cellular c...
Marine phytoplankton has developed the remarkable ability to tightly regulate the concentration of free calcium ions in the intracellular cytosol at a level of ~ 0.1 µmol /l in... -
Negative effects of ocean acidification on calcification vary within the cocc...
A large percentage of CO2 emitted into the atmosphere is absorbed by the oceans, causing chemical changes in surface waters known as ocean acidification (OA). Despite the high... -

Ocean acidification decreases the light-use efficiency in an Antarctic diatom...
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2015) was used to compute a complete and consistent set of... -
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... -
Comparative responses of two dominant Antarctic phytoplankton taxa to interac...
We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis antarctica (a prymnesiophyte) and Fragilariopsis cylindrus (a diatom) to a... -
Adaptation of a globally important coccolithophore to ocean warming and acidi...
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... -

Effects of ocean acidification on Emiliania huxleyi strain RCC 1216 (calcifying, diploid life-cycle stage) and RCC 1217 (non-calcifying, haploid life-cycle stage) were... -
Effects of increasing seawater carbon dioxide concentrations on chain formati...
Diatoms can occur as single cells or as chain-forming aggregates. These two strategies affect buoyancy, predator evasion, light absorption and nutrient uptake. Adjacent cells in...
