Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

Three decades after the discovery of cold seep systems, various sites of hydrocarbon
seepage have been found in the South China Sea (SCS). Over the past decade, these sites …

The Cryogenian Sturtian and Marinoan Snowball Earth glaciations bracket a nonglacial
interval during which Demosponge and green-algal biomarkers first appear. To understand …

Thermochemical sulfate reduction (TSR) is a set of redox reactions between organic matter
and sulfates at temperatures> 120° C, and occurs in varied environments including deeply …

Microplastics are readily accumulated in coastal sediments, where active sulfur (S) cycling
takes place. However, the effects of microplastics on S cycling in coastal sediments and their …

The global biosphere is commonly assumed to have been less productive before the rise of
complex eukaryotic ecosystems than it is today. However, direct evidence for this assertion …

Abstract The Proterozoic Eon spans Earth's middle age during which many important
transitions occurred. These transitions include the oxygenation of the atmosphere …

It has been hypothesized that the overall size of—or efficiency of carbon export from—the
biosphere decreased at the end of the Great Oxidation Event (GOE)(ca. 2,400 to 2,050 Ma) …

The marine sulfate inventory represents the largest standing pool of electron acceptors,
which, via microbial sulfate reduction, is responsible for roughly half of the organic matter …

It is not well understood how, in the immediate aftermath of the Sturtian Snowball Earth,
marine sulfur cycling resulted in a global distribution of sedimentary pyrite with δ 34 S values …
