CO2-driven seawater acidification increases photochemical stress in a green alga
Increased CO2 and associated acidification in seawater, known as ocean acidification, decreases calcification of most marine calcifying organisms. However, there is little... -
Seawater carbonate chemistry and photosynthesis of a coccolithophorid in a la...
Mixing of seawater subjects phytoplankton to fluctuations in photosynthetically active radiation (400-700 nm) and ultraviolet radiation (UVR; 280-400 nm). These irradiance... -
Ocean acidification slows nitrogen fixation and growth in the dominant diazot...
Dissolution of anthropogenic CO(2) increases the partial pressure of CO(2) (pCO(2)) and decreases the pH of seawater. The rate of Fe uptake by the dominant N(2)-fixing... -
Experiment: Combined effects of CO2, temperature, irradiance and time on the ...
In natural environments, marine biotas are exposed to a variety of simultaneously acting abiotic factors. Among these, temperature, irradiance and CO2 availability are major... -
Experiment: Physiological responses of the calcifying rhodophyte, Corallina o...
Future atmospheric CO2 levels will most likely have complex consequences for marine organisms, particulary photosynthetic calcifying organisms. Corallina officinalis L. is an... -
Experiment: Competition between calcifying and noncalcifying temperate marine...
Since pre-industrial times, uptake of anthropogenic CO2 by surface ocean waters has caused a documented change of 0.1 pH units. Calcifying organisms are sensitive to elevated... -
Light availability determines susceptibility of reef building corals to ocean...
Elevated seawater pCO2, and in turn ocean acidification (OA), is now widely acknowledged to reduce calcification and growth of reef building corals. As with other environmental... -
Seawater carbonate chemistry and effects of ocean acidification on different ...
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne and Gattuso, 2011) was used to compute a complete and consistent... -
Seawater carbonate chemistry and photosystem II photoinactivation of the coas...
We studied the interactive effects of pCO2 and growth light on the coastal marine diatom Thalassiosira pseudonana CCMP 1335 growing under ambient and expected end-of-the-century... -
Seawater carbonate chemistry and growth, carbon acquisition, and species inte...
Despite the fact that ocean acidification is considered to be especially pronounced in the Southern Ocean, little is known about CO2-dependent physiological processes and the... -
Seawater carbonate chemistry and survival, impairment of three phytoplankton ...
Sodium hypochlorite (NaOCl) is widely used to disinfect seawater in power plant cooling systems in order to reduce biofouling, and in ballast water treatment systems to prevent... -
Seawater carbonate chemistry and net photosynthesis, C/N ratio, growth rate, ...
Phytoplankton are the basis of marine food webs, and affect biogeochemical cycles. As CO2 levels increase, shifts in the frequencies and physiology of ecotypes within... -
Seawater carbonate chemistry and physiological response of the Mediterranean ...
The response of respiration, photosynthesis, and calcification to elevated pCO2 and temperature was investigated in isolation and in combination in the Mediterranean crustose... -
Seawater carbonate chemistry and calcium carbonate of Padina spp., photosynth...
Predicting the impacts of ocean acidification on coastal ecosystems requires an understanding of the effects on macroalgae and their grazers, as these underpin the ecology of... -
Interactive effects of ocean acidification and nitrogen limitation on the dia...
Climate change is expected to bring about alterations in the marine physical and chemical environment that will induce changes in the concentration of dissolved CO2 and in... -
Ocean acidification mediates photosynthetic response to UV radiation and temp...
Increasing atmospheric CO2 concentration is responsible for progressive ocean acidification, ocean warming as well as decreased thickness of upper mixing layer (UML), thus... -
Growth and photosynthesis of a diatom Cylindrotheca closterium grown under el...
The combination of elevated CO2 and the increased acidity in surface oceans is likely to have an impact on photosynthesis via its effects on inorganic carbon speciation and on... -
Rising CO2 and increased light exposure synergistically reduce marine primary...
Carbon dioxide and light are two major prerequisites of photosynthesis. Rising CO2 levels in oceanic surface waters in combination with ample light supply are therefore often... -
Reduced calcification decreases photoprotective capability in the Coccolithop...
Intracellular calcification of coccolithophores generates CO2 and consumes additional energy for acquisition of calcium and bicarbonate ions; therefore, it may correlate with... -
Future CO2-induced ocean acidification mediates the physiological performance...
The oceans take up more than 1 million tons of CO2 from the air per hour, about one-quarter of the anthropogenically released amount, leading to disrupted seawater chemistry due...
