    Pleistocene sediment offloading and the global sulfur cycle by S. Markovic, A. Paytan, U. G. Wortmann

    Published 2015-05-01
    “…Since sediment accumulation and erosion are closely tied to the formation and re-oxidation of pyrite, we use a high-resolution record of sulfur isotope ratios (<sup>34</sup>S / <sup>32</sup>S) of marine sulfate to evaluate the implications of the so-called "shelf sediment offloading" on the global sulfur cycle. Modeling of our &delta;<sup>34</sup>S record suggests that erosion during sea level lowstands was only partly compensated by increased sedimentation during times of rising sea level and sea level highstands. …”

    Constraints on the late Ediacaran sulfur cycle from carbonate associated sulfate by Tostevin, R, He, T, Turchyn, A, Wood, R, Penny, A, Bowyer, F, Antler, G, Shields, G

    Published 2017
    “…We report new sulfur isotope compositions (δ34S) in carbonate associated sulfate (CAS) and pyrite from the lower Nama Group, Namibia (∼550 to &lt;547 Ma), and use these data to interrogate terminal Ediacaran sulfur cycle dynamics. Our extraction method utilizes an improved pre-leaching procedure that reduces the likelihood of contamination from matrix-bound sulfur. …”

    Sulfur Cycling as a Viable Metabolism under Simulated Noachian/Hesperian Chemistries by James A. W. Oliver, Matthew Kelbrick, Nisha K. Ramkissoon, Amy Dugdale, Ben P. Stephens, Ezgi Kucukkilic-Stephens, Mark G. Fox-Powell, Susanne P. Schwenzer, André Antunes, Michael C. Macey

    Published 2022-04-01
    “…Microbial communities exhibited distinct growth dynamics and taxonomic composition, comprised of sulfur-cycling bacteria, represented by either sulfate-reducing or sulfur-oxidising bacteria, and additional heterotrophic halophiles. …”

    Cryptic roles of tetrathionate in the sulfur cycle of marine sediments: microbial drivers and indicators by S. Mandal, S. Bhattacharya, C. Roy, M. J. Rameez, J. Sarkar, T. Mapder, T. Mapder, S. Fernandes, A. Peketi, A. Mazumdar, W. Ghosh

    Published 2020-09-01
    “…<p>To explore the potential role of tetrathionate in the sedimentary sulfur cycle, population ecology of microorganisms capable of metabolizing this polythionate was revealed at 15–30&thinsp;cm resolution along two, <span class="inline-formula">∼3</span>&thinsp;m long, cores collected from 530 and 580&thinsp;m below the sea level, off India's west coast, within the oxygen minimum zone (OMZ) of the Arabian Sea. …”

    A global perturbation to the sulfur cycle during the Toarcian Oceanic Anoxic Event by Gill, B, Lyons, T, Jenkyns, H

    Published 2011
    “…Importantly, our results indicate that the sulfur isotope excursion reflects a globally significant perturbation in the sulfur cycle and that pyrite burial in the North European Epeiric Seaway alone cannot account for the excursion. …”

    A Cryptic Sulfur Cycle in Oxygen-Minimum-Zone Waters off the Chilean Coast by Canfield, D. E., Thamdrup, B., De Brabandere, L., Dalsgaard, T., Revsbech, N. P., Ulloa, O., Stewart, Frank J., DeLong, Edward Francis

    Published 2017
    “…These processes may have been overlooked because in nature, the sulfide produced by sulfate reduction immediately oxidizes back to sulfate. This cryptic sulfur cycle is linked to anammox and other nitrogen cycling processes, suggesting that it may influence biogeochemical cycling in the global ocean.…”
