• #### Multiple sulfur isotope constraints on the modern sulfur cycle ﻿

(Elsevier BV, 2014)
We present 28 multiple sulfur isotope measurements of seawater sulfate $(δ^{34}S_{SO_{4}} and Δ^{33}S_{SO_4})$ from the modern ocean over a range of water depths and sites along the eastern margin of the Pacific Ocean. ...
• #### On the mechanisms of sulfur isotope fractionation during microbial sulfate reduction ﻿

(2014-06-06)
Underlying all applications of sulfur isotope analyses is our understanding of isotope systematics. This dissertation tests some fundamental assumptions and assertions, drawn from equilibrium theory and a diverse body of ...
• #### Seasonal fluxes of carbonyl sulfide in a midlatitude forest ﻿

(Proceedings of the National Academy of Sciences, 2015)
Carbonyl sulfide (OCS), the most abundant sulfur gas in the atmosphere, has a summer minimum associated with uptake by vegetation and soils, closely correlated with CO2. We report the first direct measurements to our ...
• #### Triple oxygen and multiple sulfur isotope constraints on the evolution of the post-Marinoan sulfur cycle ﻿

(Elsevier BV, 2016)
Triple oxygen isotopes within post-Marinoan barites have played an integral role in our understanding of Cryogenian glaciations. Reports of anomalous View the MathML source values within cap carbonate hosted barites however ...
