Orphan V, Hinrichs K, Ussler 3rd W, Paull C, Taylor L, Sylva S, et al.
Appl Environ Microbiol . 2001 Apr; 67(4):1922-34. PMID: 11282650
The oxidation of methane in anoxic marine sediments is thought to be mediated by a consortium of methane-consuming archaea and sulfate-reducing bacteria. In this study, we compared results of rRNA...

Sessions A, Burgoyne T, Hayes J
Anal Chem . 2001 Feb; 73(2):200-7. PMID: 11199966
The H3 factor, K, is a parameter required in high-precision, mass spectrometric analyses of hydrogen isotopic abundances. When H2 is used as the sample gas, R* = R - Ki2,...

Sessions A, Burgoyne T, Hayes J
Anal Chem . 2001 Feb; 73(2):192-9. PMID: 11199965
Two fundamentally different approaches, termed "pointwise" and "peakwise," are currently used to correct hydrogen isotope ratio monitoring data for the presence of H3+ ion contributions. Consideration of the underlying assumptions...

Hinrichs K, Hayes J, Sylva S, Brewer P, Delong E
Nature . 1999 May; 398(6730):802-5. PMID: 10235261
Large amounts of methane are produced in marine sediments but are then consumed before contacting aerobic waters or the atmosphere. Although no organism that can consume methane anaerobically has ever...

Leckrone K, Hayes J
Anal Chem . 1998 Jul; 70(13):2737-44. PMID: 9666739
Formation of HCO2+ from CO2 and background H2O in isotope ratio mass spectrometers has been examined in detail. The process is troublesome because its product is not resolved from 13C16O2+....
