Airborne in-situ observations of carbon dioxide (CO2) were made during 7 intensive measurement campaigns between November 2001 and April 2003 as part of the SPURT project. Vertical profiles and latitu...
The partial pressure of carbon dioxide (pCO2), concentration of total dissolved inorganic carbon, and total alkalinity were measured at both high tide and low tide in the surface water of three Georgi...
Carbon dioxide (CO2) and methane (CH4) are the two most important anthropogenic greenhouse gases. SCIAMACHY on ENVISAT is the first satellite instrument whose measurements are sensitive to concentrati...
The sensitivity of an operational CO2-responsive land surface model (the ISBA-A-gs model of Météo-France) to the atmospheric CO2 concentration, (CO2), is investigated for 3 vegetation types (winter wh...
The marine aragonite cycle has been included in the global biogeochemical model PISCES to study the role of aragonite in shallow water CaCO3 dissolution. Aragonite production is parameterized as a fun...
We studied the effects of elevated CO2 concentrations (0.03%vs. 0.1%) on light absorption, membrane permeability, growth, and carbon fixation under photosynthetically active radiation (PAR) and ultrav...
Carbon fixation was analyzed in a series of stratified lakes with oxygen–sulfide interfaces following14 Cbicarbonate incorporation into oxygenic phototrophic, anoxygenic phototrophic (photosynthetic s...
The partial pressure of carbon dioxide (pCO2), concentration of total dissolved inorganic carbon, and total alkalinity were measured at both high tide and low tide in the surface water of three Georgi...
We compiled a large data-set from 22 cruises spanning from 1991 to 2003, of the partial pressure of CO2 (pCO2) in surface waters over the continental shelf (CS) and adjacent open ocean (43° to 46° S; ...
The exchange fluxes of carbon dioxide between wet arctic polygonal tundra and the atmosphere were investigated by the micrometeorological eddy covariance method. The investigation site was situated in...
Surface energy fluxes were measured using Bowen-Ratio Energy Balance technique (BREB) and eddy correlation system at Luancheng of Hebei Province, on the North China Plain from 1999 to 2001...
2007Vol.47No.5pp.892-896DOI: High Temperature Spectrum for ν3 Band of Carbon Dioxide SONG Xiao-Shu,1,2 YANG Xiang-Dong,1 GUO Yun-Dong,1 WANG Jun,1 CHENG Xin-Lu,1 and LING-HU Rong...
专著信息 书名 Inorganic carbonate as carbon dioxide source for the synthesis of trifluoromethylated cyclic carbonates 语种 英文 撰写或编译 作者 Zhong-Xing Jiang,Feng-Ling Qing 第一作者单位 出版社 J. Fluorine Chem., 2003, 123, ...
期刊信息 篇名 pH Sensitive polypropylene porous membrane prepared by grafting acrylic acid in supercritical carbon dioxide 语种 英文 撰写或编译 撰写 作者 Yong Wang,Zhimin Liu*,Buxing Han,Zexuan Dong,Jiaqiu Wang,Donghai ...
We report the results of a field study, in productive waters off California, of the factors that control the particulate cadmium (Cd) : phosphorus (P) composition of natural assemblages of marine phyt...
