Methane emissions from Lompolojänkkä, a Finnish aapa mire within the Arctic Circle, were studied by non-intrusive Keeling plot methods, to place better constraints on the seasonal variations in isotopic signature of methane (δ13CCH4) emitted from

Atmospheric CO at Egham in SE England has shown a marked and progressive decline since 1997, following adoption of strict controls on emissions. The Egham site is uniquely positioned to allow both assessment and comparison of ‘clean Atlantic backgr

Arctic methane sources: Isotopic evidence for atmospheric inputs

Autor: S. Sriskantharajah, P. B. R. Nisbet-Jones, Rachael H. James, Jens Greinert, David Lowry, Mathias Lanoisellé, Rebecca Fisher, Andreas Stohl, Euan G. Nisbet, Jürgen Mienert, Ove Hermansen, C. M. R. Fowler, C. Lund Myhre

By comparison of the methane mixing ratio and the carbon isotope ratio (δ13CCH4) in Arctic air with regional background, the incremental input of CH4 in an air parcel and the source δ13CCH4 signature can be determined. Using this technique the bulk

Emission of methane from plants

Autor: Rebecca Fisher, Robert H. Nimmo, Christopher J. Howe, Patrick M. Crill, Enrique López-Juez, Euan G. Nisbet, Angela V. Gallego-Sala, David Lowry, P.B.R Nisbet, S. Sriskantharajah, Emily Shuckburgh, Derek S. Bendall, R.E.R Nisbet, Edward R. C. Hornibrook

It has been proposed that plants are capable of producing methane by a novel and unidentified biochemical pathway. Emission of methane with an apparently biological origin was recorded from both whole plants and detached leaves. This was the first re

High-precision, automated stable isotope analysis of atmospheric methane and carbon dioxide using continuous-flow isotope-ratio mass spectrometry

Autor: Rebecca Fisher, David Lowry, Euan G. Nisbet, S. Sriskantharajah, Owen Wilkin

Publikováno v: Rapid communications in mass spectrometry : RCM. 20(2)

Small-scale developments have been made to an off-the-shelf continuous-flow gas chromatography/isotope-ratio mass spectrometry (CF-GC/IRMS) system to allow high-precision isotopic analysis of methane (CH(4)) and carbon dioxide (CO(2)) at ambient conc
