Pleistocene sediment offloading and the global sulfur cycle
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 δ<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
Published 2017“…We report new sulfur isotope compositions (δ34S) in carbonate associated sulfate (CAS) and pyrite from the lower Nama Group, Namibia (∼550 to <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. …”

A Cryptic Sulfur Cycle in Oxygen-Minimum-Zone Waters off the Chilean Coast
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.…”
