Reduced calcification of marine plankton in response to increased atmospheric CO2
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 underlying sediments.Expand

Ocean acidification due to increasing atmospheric carbon dioxide
The oceans cover over two-thirds of the Earth’s surface. They play a vital role in global biogeochemical cycles, contribute enormously to the planet’s biodiversity and provide a livelihood forExpand

CO2 and HCO3 ߚ uptake in marine diatoms acclimated to different CO2 concentrations
Rates of cellular uptake of CO2 and HCO3 2 during steady-state photosynthesis were measured in the marine diatoms Thalassiosira weissflogii and Phaeodactylum tricornutum,acclimated to CO2 partialExpand

Enhanced biological carbon consumption in a high CO2 ocean
The oceans have absorbed nearly half of the fossil-fuel carbon dioxide (CO2) emitted into the atmosphere since pre-industrial times, causing a measurable reduction in seawater pH and carbonateExpand

Effects of CO2 Enrichment on Marine Phytoplankton
Rising atmospheric CO2 and deliberate CO2 sequestration in the ocean change seawater carbonate chemistry in a similar way, lowering seawater pH, carbonate ion concentration and carbonate saturationExpand

Changes in primary productivity and chlorophyll a in response to iron fertilization in the Southern Polar Frontal Zone
EisenEx�the second in situ iron enrichment experiment in the Southern Ocean�was performed in the Atlantic sector over 3 weeks in November 2000 with the overarching goal to test the hypothesis thatExpand

Carbon acquisition of bloom-forming marine phytoplankton
Carbon acquisition in relation to CO2 supply was investigated in three marine bloom-forming microalgae, the diatom Skeletonema costatum, the flagellate Phaeocystis globosa, and the coccolithophoridExpand

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 theExpand

Testing the effect of CO2 concentration on the dynamics of marine heterotrophic bacterioplankton
To date no study exists that directly addresses changes in dynamics of heterotrophic bacteria in surface waters in relation to partial pressure of CO 2 (pCO2). Therefore, we studied the effect ofExpand

Decreasing marine biogenic calcification: A negative feedback on rising atmospheric pCO2
In laboratory experiments with the coccolithophore species Emiliania huxleyi and Gephyrocapsa oceanica, the ratio of particulate inorganic carbon (PIC) to particulate organic carbon (POC) productionExpand
