The O2, pH and Ca2+ Microenvironment of Benthic Foraminifera in a High CO2 World
Ocean acidification (OA) can have adverse effects on marine calcifiers. Yet, phototrophic marine calcifiers elevate their external oxygen and pH microenvironment in daylight,... -
Impact of changing carbonate chemistry, temperature, and salinity on growth a...
The present study investigated the combined effects of ocean acidification, temperature, and salinity on growth and test degradation of Ammonia aomoriensis. This species is one... -
Seawater carbonate chemistry, biomass and metabolic rates (leucine incorporat...
Experimental results related to the effects of ocean acidification on planktonic marine microbes are still rather inconsistent and occasionally contradictory. Moreover,... -
Seawater carbonate chemistry, productivity and calcification of Marginopora v...
Changes in the seawater carbonate chemistry (ocean acidification) from increasing atmospheric carbon dioxide (CO2 ) concentrations negatively affect many marine calcifying... -
Seawater carbonate chemistry, survival rate, shell size, calcification rate o...
The present study investigated the effects of ocean acidification and temperature increase on Neogloboquadrina pachyderma (sinistral), the dominant planktonic foraminifer in the... -
Seawater carbonate chemistry and biometry and dissolution features of the ben...
Culturing experiments were performed with the benthic foraminifer Ammonia aomoriensis from Flensburg Fjord, western Baltic Sea. The experiments simulated a projected rise in... -
Seawater carbonate chemistry and benthic foraminifera Ammonia sp. uranium inc...
The chemical and isotopic composition of foraminiferal shells (so-called proxies) reflects the physico-chemical properties of the seawater. In current day paleoclimate research,... -
Seawater carbonate chemistry and benthic foraminifera Ammonia sp. mass, size,...
About 30% of the anthropogenically released CO2 is taken up by the oceans; such uptake causes surface ocean pH to decrease and is commonly referred to as ocean acidification... -
Seawater carbonate chemistry, calcification rate, oxygen production, maximum ...
The effects of elevated CO2 and temperature on photosynthesis and calcification in the calcifying algae Halimeda macroloba and Halimeda cylindracea and the symbiont-bearing... -
Seawater carbonate chemistry and biological processes of Amphisorus hemprichi...
Ocean acidification, which like global warming is an outcome of anthropogenic CO2emissions, severely impacts marine calcifying organisms, especially those living in coral reef... -
Seawater carbonate chemistry and impacts of calcium and carbonate ion concent...
Laboratory culture experiments were conducted to determine effects of seawater carbonate ion concentration ([CO32-]), and thereby calcite saturation state, on Mg and Sr... -
Seawater carbonate chemistry and boron incorporation of planktic foraminifer ...
Culture experiments with living planktic foraminifers reveal that the ratio of boron to calcium (B/Ca) in Orbulina universa increases from 56 to 92 µmol mol-1 when pH is raised... -
Seawater carbonate chemistry and biological processes of foraminifera, Globig...
Specimens of two species of planktic foraminifera, Globigerinoides ruber and Globigerinella siphonifera, were grown under controlled laboratory conditions at a range of... -
Incorporation of Mg and Sr in calcite of cultured benthic foraminifera (Heter...
We investigated the effect of the calcium concentration in seawater and thereby the calcite saturation state (omega) on the magnesium and strontium incorporation into benthic... -
Seawater carbonate chemistry and Globigerinoides sacculifer biological proces...
The effect of carbonate ion concentration ([CO3]) on calcification rates estimated from shell size and weight was investigated in the planktonic foraminifera Orbulina universa... -
Seawater carbonate chemistry and processes during experiments with benthic fo...
Evidence of increasing concentrations of dissolved carbon dioxide, especially in the surface ocean and its associated impacts on calcifying organisms, is accumulating. Among... -
Seawater carbonate chemistry and carbon and oxygen isotopes during experiment...
Stable oxygen and carbon isotope measurements on biogenic calcite and aragonite have become standard tools for reconstructing past oceanographic and climatic change. In aquatic... -
Seawater carbonate chemistry, processes and elements during experiments with ...
We investigate the sensitivity of U/Ca, Mg/Ca, and Sr/Ca to changes in seawater [CO3[2-]] and temperature in calcite produced by the two planktonic foraminifera species,... -
Investigating the chemistry and biology of porewater and seawater in a site h...
We investigated seawater microbial abundance, activity and diversity in a site strongly influenced by submarine groundwater discharge (SGD). Three sampling campaigns (August... -
Investigating the contribution of SGD to the coastal microbial community with...
We investigated seawater microbial abundance, activity and diversity throughthree laboratory-controlled bottle incubations mimicking different mixing scenarios between SGD...
