Effect of carbonate ion concentration and irradiance on calcification in planktonic foraminifera
carbonate ion concentration and irradiance calcification planktonic foraminifera
2010/1/21
The effect of carbonate ion concentration ([CO32−]) on calcification rates estimated from shell size and weight was investigated in the planktonic foraminifera Orbulina universa and Globigerinoi...
Impact of seawater pCO2 on calcification and Mg/Ca and Sr/Ca ratios in benthic foraminifera calcite: results from culturing experiments with Ammonia tepida
seawater pCO2 calcification and Mg/Ca and Sr/Ca ratios benthic foraminifera calcite culturing experiments Ammonia tepida
2010/1/21
Evidence of increasing concentrations of dissolved carbon dioxide, especially in the surface ocean and its associated impacts on calcifying organisms, is accumulating. Among these organisms, benthic a...
Physiological controls on seawater uptake and calcification in the benthic foraminifer Ammonia tepida
Physiological controls seawater uptake calcification benthic foraminifer Ammonia tepida
2010/1/21
To analyze the relation between seawater uptake and calcification, we incubated juveniles of the benthic foraminifer Ammonia tepida with various fluorescent probes and visualised them afterwards with ...
From laboratory manipulations to Earth system models:scaling calcification impacts of ocean acidification
laboratory manipulations Earth system models calcification impacts ocean acidification
2010/1/21
The observed variation in the calcification responses of coccolithophores to changes in carbonate chemistry paints a highly incoherent picture, particularly for the most commonly cultured "species", E...
Calcification of the cold-water coral Lophelia pertusa,under ambient and reduced pH
Calcification cold-water coral Lophelia pertusa ambient and reduced pH
2010/1/20
The cold-water coral Lophelia pertusa is one of the few species able to build reef-like structures and a 3-dimensional coral framework in the deep oceans. Furthermore, deep cold-water coral bioherms m...
Assessing the potential long-term increase of oceanic fossil fuel CO2 uptake due to CO2-calcification feedback
potential long-term increase oceanic fossil fuel CO2-calcification feedback
2010/1/14
Plankton manipulation experiments exhibit a wide range of sensitivities of biogenic calcification to simulated anthropogenic acidification of the ocean, with the "lab rat" of planktic calcifiers, Emil...
CO32− concentration and pCO2 thresholds for calcification and dissolution on the Molokai reef flat,Hawaii
CO32− concentration pCO2 thresholds calcification dissolution
2010/1/13
The severity of the impact of elevated atmospheric pCO2 to coral reef ecosystems depends, in part, on how seawater pCO2 affects the balance between calcification and dissolution of carbonate sediments...
