Journal ArticleDOI
Sulfate was a trace constituent of Archean seawater
Sean A. Crowe,Sean A. Crowe,Guillaume Paris,Sergei Katsev,CarriAyne Jones,CarriAyne Jones,Sang-Tae Kim,Aubrey L. Zerkle,Sulung Nomosatryo,David A. Fowle,Jess F. Adkins,Alex L. Sessions,James Farquhar,Donald E. Canfield +13 more
TL;DR: Low levels of sulfate allowed for the preservation of mass-independent isotope signatures in the Archean, yet open questions frustrate the translation of modern measurements of sulfur isotope fractionations into estimates of Archean seawater sulfate concentrations.
Journal ArticleDOI
Photoferrotrophs thrive in an Archean Ocean analogue
Sean A. Crowe,CarriAyne Jones,Sergei Katsev,Cédric Magen,Andrew H. O'Neill,Arne Sturm,Donald E. Canfield,G. Douglas Haffner,Alfornso Mucci,Bjørn Sundby,David A. Fowle +10 more
TL;DR: It is proposed that similar microbial communities, including populations of sulfate reducers and photoferrotrophic GSB, likely populated the chemoclines of ancient ferruginous oceans, driving the genesis of BIFs and fueling early marine productivity.
Journal ArticleDOI
The methane cycle in ferruginous Lake Matano.
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
Modeling dissolved oxygen dynamics and hypoxia
TL;DR: A review of oxygen dynamics models that have significantly contributed to a better understanding of the effects of natural processes and human perturbations on the development of hypoxia can be found in this article.
Journal ArticleDOI
Factors controlling long-term phosphorus efflux from lake sediments: Exploratory reactive-transport modeling
TL;DR: In this paper, a global sensitivity analysis on a generic diagenetic reaction-transport model (RTM) was performed to elucidate the effects of environmental, thermodynamic, and kinetic factors on the magnitudes of phosphorus release fluxes from aquatic sediments under a range of conditions typically found in lake sediments.
