Gas transport in firn: multiple-tracer characterisation and model intercomparison for NEEM, Northern Greenland
Christo Buizert,Patricia Martinerie,Vasilii V. Petrenko,Vasilii V. Petrenko,Jeffrey P. Severinghaus,Cathy M. Trudinger,Emmanuel Witrant,Jean Rosen,Anais Orsi,Mauro Rubino,Mauro Rubino,David Etheridge,David Etheridge,L. P. Steele,Christopher Hogan,Johannes C. Laube,William T. Sturges,Vladimir Levchenko,Andrew M. Smith,Ingeborg Levin,Thomas J. Conway,Edward J. Dlugokencky,P. M. Lang,Kenji Kawamura,Theo M. Jenk,James W. C. White,Todd Sowers,Jakob Schwander,Thomas Blunier +28 more
TL;DR: In this paper, the authors used an ensemble of ten reference tracers of known atmospheric history to characterise the transport properties of the NEEM site in Northern Greenland and found that diffusivity does not vanish completely in the lock-in zone, as is commonly assumed.
Journal ArticleDOI
14CH4 Measurements in Greenland Ice: Investigating Last Glacial Termination CH4 Sources
Vasilii V. Petrenko,Andrew M. Smith,Edward J. Brook,Dave Lowe,Katja Riedel,Gordon Brailsford,Quan Hua,Hinrich Schaefer,Niels Reeh,Ray F. Weiss,David Etheridge,Jeffrey P. Severinghaus +11 more
TL;DR: Measurements of 14CH4 in glacial ice, targeting this transition, performed by using ice samples obtained from an ablation site in west Greenland suggest that wetland sources were likely responsible for the majority of the Younger Dryas–Preboreal CH4 rise.
Journal ArticleDOI
A New Method for Analyzing 14C of Methane in Ancient Air Extracted from Glacial Ice
Vasilii V. Petrenko,Andrew M. Smith,Gordon Brailsford,Katja Riedel,Quan Hua,Dave Lowe,Jeffrey P. Severinghaus,Vladimir Levchenko,T. Bromley,Rowena Moss,Jens Mühle,Edward J. Brook +11 more
TL;DR: In this paper, a new method was developed for measuring radiocarbon of methane (14CH4) in ancient air samples extracted from glacial ice and dating 11,000-15,000 calendar years before present.
Journal ArticleDOI
High-precision 14C measurements demonstrate production of in situ cosmogenic 14CH4 and rapid loss of in situ cosmogenic 14CO in shallow Greenland firn
Vasilii V. Petrenko,Vasilii V. Petrenko,Vasilii V. Petrenko,Jeffrey P. Severinghaus,Andrew M. Smith,Katja Riedel,Daniel Baggenstos,Christina M. Harth,Anais Orsi,Quan Hua,Peter Franz,Yui Takeshita,Gordon Brailsford,Ray F. Weiss,Christo Buizert,Andrew G. Dickson,Hinrich Schaefer +16 more
TL;DR: In this paper, the authors measured 14 CH 4 and 14 CO content in glacial firn with unprecedented precision to advance understanding of the in situ 14 C component, and demonstrated that a significant amount of 14 CO is produced by cosmic rays in natural ice.
Journal ArticleDOI
Methane from the East Siberian Arctic Shelf
Vasilii V. Petrenko,David Etheridge,Ray F. Weiss,Edward J. Brook,Hinrich Schaefer,Jeffrey P. Severinghaus,Andrew M. Smith,Dave Lowe,Quan Hua,Katja Riedel +9 more
TL;DR: Methane (CH4) release resulting from thawing Arctic permafrost “is a likely positive feedback to climate warming” according to Shakhova et al.
