Presents data for goethites from an ironstone Ordovician Neda Formation (Wisconsin, USA), which suggest that 440 Myr ago atmospheric partial pressure of CO2 (Pco2) was approximately 16 times higher than today. Investigating the role of changing atmospheric CO2 concentrations in controlling global ...

Among the proposed causes are a drop in the partial pressure of atmospheric carbon dioxide (ip/iCOsub2/sub) in combination with orbital forcing. An additional complication is the large uncertainty in the magnitude and age of the reconstructed ip/iCOsub2/sub values and the low temporal ...
Chemical Weathering, Atmospheric CO2, and Climate There has been considerable controversy concerning the role of chemical weathering in the regulation of the atmospheric partial pressure of carbon dioxide,... LR Kump,SL Brantley,MA Arthur - 《Annual Review of Earth & Planetary Sciences》 被引量: ...
The partial pressure of CO2(pCO2),methane(CH4) and Nitrous oxide(N2O) were measured in the surface water of Dalian Bay during 2 surveys from 2009 to 2010.The results showed that pCO2 ranged from 44.00 to 51.55 Pa in autumn,with an average of 47.77 Pa.While in the winter it ranged fro...
Seedlings of two mangrove species, Avicennia marina and Aegiceras corniculatum , were grown in a range of salinities and humidities in controlled environment chambers, and Phaseolus vulgaris plants were grown in the glasshouse. The fractionation of carbon isotopes in the three species was correlated...
atm for seawater partial pressure of CO2 (pCO2) and < 1 ??atm for air pCO2. The MAPCO2 maintains this level of uncertainty for over 400 days of autonomous operation. MAPCO2 measurements are consistent with shipboard seawater pCO2 measurements and GLOBALVIEW-CO2 boundary layer atmospheric values....
(RubisCO)73, which is responsible for the fixation of CO2into organic compounds. The carbon fractionation between marine species and the partial pressure of atmospheric carbon dioxide (pCO2) is clearly CO2-dependent, with higherpCO2leading to higher carbon isotope fractionation, which have been tested...
Therefore if we increase the partial pressure ofCO2in theatmosphere(e.g. by burning fossil fuels) then this difference increases, and moreCO2passes fromatmosphereto the ocean than in the other direction. This causes the oceans to take up moreCO2until the partial pressures are in equilibrium ...
