Sean A. Crowe,Sergei Katsev,Sergei Katsev,Karla Leslie,Arne Sturm,Cédric Magen,Cédric Magen,Sulung Nomosatryo,Mary A. Pack,John D. Kessler,William S. Reeburgh,Jennifer A. Roberts,Luis A. González,G. Douglas Haffner,Alfonso Mucci,Alfonso Mucci,Bjørn Sundby,Bjørn Sundby,David A. Fowle +18 more
TL;DR: It is found that methane is important in C cycling, even in this very Fe-rich environment, which is analogous to conditions in the ferruginous oceans thought to prevail during much of the Archean Eon.
Journal ArticleDOI
Methane sources and sinks in Lake Kivu
Natacha Pasche,Natacha Pasche,Martin Schmid,Francisco Vazquez,Carsten J. Schubert,Alfred Wüest,Alfred Wüest,John D. Kessler,Mary A. Pack,William S. Reeburgh,Helmut Bürgmann +10 more
TL;DR: A recent study reported that CH 4 concentrations in Lake Kivu have increased by up to 15% in the last 30 years and that accumulation at this rate could lead to catastrophic outgassing by ∼2100 as mentioned in this paper.
Journal ArticleDOI
A method for measuring methane oxidation rates using low levels of 14C-labeled methane and accelerator mass spectrometry
Mary A. Pack,M. B. Heintz,William S. Reeburgh,Susan E. Trumbore,David L. Valentine,Xiaomei Xu,Ellen R. M. Druffel +6 more
TL;DR: In this article, a low-level accelerator mass spectrometric (AMS) method was proposed to estimate the rate of methane oxidation in the marine environment using levels of 14C-CH4 below transportation regulations.
Journal ArticleDOI
Rapid sample preparation of dissolved inorganic carbon in natural waters using a headspace-extraction approach for radiocarbon analysis by accelerator mass spectrometry
Pan Gao,Pan Gao,Xiaomei Xu,Liping Zhou,Mary A. Pack,Sheila Griffin,Guaciara M. Santos,John Southon,Kexin Liu +8 more
TL;DR: In this article, a high-throughput headspace-extraction method for the preparation of dissolved inorganic carbon (DIC) from water samples for radiocarbon (14C) analysis by accelerator mass spectrometry (AMS) is presented.
Journal ArticleDOI
Methane oxidation in the eastern tropical North Pacific Ocean water column
Mary A. Pack,M. B. Heintz,William S. Reeburgh,Susan E. Trumbore,David L. Valentine,Xiaomei Xu,Ellen R. M. Druffel +6 more
TL;DR: In this article, a tracer-based method with low-level 14C-CH 4 (LL 14C) and 3H-CH4 (3H) tracers were used to measure the methane oxidation rate in the eastern tropical north Pacific (ETNP) water column.
