Defining the character of the methanogenic types with carbon and hydrogen isotopes not only provides information about the environment of formation, it is also most useful in distinguishing biogenic from thermogenic methane gases. 展开 DOI: 10.1016/0016-7037(86)90346-7 被引量: 2154 ...
Methane is the main component in natural gas, which fuels industrial plants, powers homes and runs air conditioners, among other applications. Why do methane emissions pose a risk to the environment? Methane is about 80 times more powerful at warming the atmosphere than carbon dioxide over a 20...
W Ding,Z Cai,D Wang - 《Atmospheric Environment》 被引量: 355发表: 2004年 An ecological perspective on methane emissions from northern wetlands Since global climate models predict the greatest temperature and precipitation changes at high latitudes, and as the largest areas of wetland (346 × 106...
Microbial and thermogenic methane migrates towards the seabed where some is utilised during microbially-mediated anaerobic oxidation. Excess methane escape... Judd, AG - 《Environmental Geology》 被引量: 203发表: 2004年 Modifications of the local environment by natural marine hydrocarbon seeps Author(...
(v.0.13.1)42under the tidymodels environment (v.0.1.4)43. To capture seasonal patterns, we constructed a different random forest model for each month, but first we explored all data together to find the optimal model structure. To do this, we first removed several independent variables that...
Coal-bed methane resources as a clean source of energy,it can change the unreasonable energy structure,reduce the air pollution,protect human health and environment.In the view of sustainable development in the 21st century,we should enhance geological tectonic research on coal basins,build the coal...

ecosystems was likely low and energy limited, i.e., limited by the availability of electron donors rather than nutrients such as nitrogen, phosphorus, or iron13,14. Whether and how the evolution of a primitive biosphere formed by these metabolisms influenced the planetary environment globally is ...
Biogenic Methane, Hydrogen Escape, and the Irreversible Oxidation of Early Earth. Explains the factors that caused the irreversible oxidation of the Earth's surface environment about 2.4 and 2.2 billion years ago. Low oxygen content of ... Catling,David,C.,... - 《Science》 被引量: 0发表:...
Methane, microbes and models: fundamental understanding of the soil methane cycle for future predictions Methane is an important greenhouse gas and microbes in the environment play major roles in both global methane emissions and terrestrial sinks. However, a ... Loc Nazaries,JC Murrell,P Millard,...
