Present state of global wetland extent and wetland methane modelling: methodology of a model inter-comparison project (WETCHIMP)

The Wetland and Wetland CH4 Intercomparison of Models Project (WETCHIMP) was created to evaluate our present ability to simulate large-scale wetland characteristics and corresponding methane (CH4) emissions. A multi-model comparison is essential to evaluat ...

Present state of global wetland extent and wetland methane modelling: conclusions from a model inter-comparison project (WETCHIMP)

Jed Oliver Kaplan

Global wetlands are believed to be climate sensitive, and are the largest natural emitters of methane (CH4). Increased wetland CH4 emissions could act as a positive feedback to future warming. The Wetland and Wetland CH4 Inter-comparison of Models Project ...

Carbon isotope constraints on the deglacial CO2 rise from ice cores

Jérôme Chappellaz

ICE-CORE reconstructions of atmospheric methane concentrations for the past 220 kyr have revealed large variations associated with different climatic periods1-4. But the phase relationship between climate and methane has been uncertain because of dating un ...

Inoculum origin and adaptation had no influence on biomethane potential results with different substrates

Christof Holliger, Marc Deront, Nathalie Bachmann

Biomethane potential (BMP) tests are a valuable tool to design different parts of full-scale anaerobic digestion plants. Recent inter-laboratory studies have shown that the results of BMP tests can vary considerably and a comparison of BMP test norm protoc ...

Magnitude and seasonality of wetland methane emissions from the Hudson Bay Lowlands (Canada)

Jed Oliver Kaplan, Isabelle Bey, Jérôme Drevet

The Hudson Bay Lowlands (HBL) is the second largest boreal wetland ecosystem in the world and an important natural source of global atmospheric methane. We quantify the HBL methane emissions by using the GEOS-Chem chemical transport model to simulate aircr ...

Ecological Controls of Aerobic and Anaerobic Microbial Activities and Potential Impacts on Greenhouse Gases in Regenerating Peatlands

Andy Siegenthaler

Peatlands represent massive global carbon (C) pools and sinks. Carbon accumulation depends on the ratio between net primary production and decomposition of organic matter, both of which can change under projected increases of atmospheric carbon dioxide (CO ...

The El Nino-Southern Oscillation and wetland methane interannual variability

Jed Oliver Kaplan

Global measurements of atmospheric methane (CH4) concentrations continue to show large interannual variability whose origin is only partly understood. Here we quantify the influence of the El Nino-Southern Oscillation (ENSO) on wetland CH4 emissions, which ...

Spatial Heterogeneity of Methane Ebullition in a Large Tropical Reservoir

Alfred Johny Wüest, Bernhard Wehrli

Tropical reservoirs have been identified as important methane (CH4) sources to the atmosphere, primarily through turbine and downstream degassing. However, the importance of ebullition (gas bubbling) remains unclear. We hypothesized that ebullition is a di ...

Growth of carbon nanotubes and microfibers over stainless steel mesh by cracking of methane

Albert Renken, Lioubov Kiwi

The

{La}_{2}{NiO}_{4}

film was synthesized on the 304 stainless steel (SS) mesh. The hydrogen reduction of La2NiO4 generated homogeneous nanocatalyst particles (probably

{Ni}/{La}_2{O}_{3}

) over which methane was cracked, producing carbon notubes/micro ...

Influence of temperature and high acetate concentrations on methanogenensis in lake sediment slurries

Christof Holliger, Bernhard Wehrli

Methanogenesis from main methane precursors H2/CO2 and acetate was investigated in a temperature range of 2–70 °C using sediments from Lake Baldegg, Switzerland. Psychrophilic, psychrotrophic, mesophilic, and thermophilic methanogenic microbial communities ...
