Sedimentary pyrite sulfur isotopes track the local dynamics of the Peruvian oxygen minimum zone [PDF]
Nature Communications, 2021 To explore the importance of local vs. global sulfur-cycle controls on variations in pyrite sulfur isotopes, the authors couple carbon-nitrogen-sulfur concentrations and stable isotopes of sediments from the Peruvian oxygen minimum zone, identifying a ...

Strong local, not global, controls on marine pyrite sulfur isotopes. [PDF]
Sci Adv, 2021 Local to regional depositional environment controls the S-isotopic composition of sedimentary pyrite. Understanding variation in the sulfur isotopic composition of sedimentary pyrite (δ34Spyr) is motivated by the key role of sulfur biogeochemistry in ...

Constraining the atmospheric OCS budget from sulfur isotopes. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Carbonyl sulfide (OCS) is a key proxy of the global photosynthesis rate, but the greatest uncertainty in the OCS cycle is its missing source.

Major excursions in sulfur isotopes linked to permafrost change in Eurasia during the last 50,000 years. [PDF]
Nat GeosciWe identify a major sulfur isotope excursion in Eurasian faunal bone collagen from the last 50,000 years, here termed the Late Pleniglacial Sulfur Excursion.

Molecular insights into the dynamic relationship between respiration rate and sulfur isotope effect [PDF]
Applied and Environmental MicrobiologyMicrobial sulfate reduction and its resulting sulfur isotope effects are crucial for understanding the past and present sulfur cycle. Microbial S-isotope effects have often been explained by their inverse correlation with the cell-specific sulfur ...

Multiple sulfur isotopes fractionations associated with abiotic sulfur transformations in Yellowstone National Park geothermal springs. [PDF]
Geochem Trans, 2014 BackgroundThe paper presents a quantification of main (hydrogen sulfide and sulfate), as well as of intermediate sulfur species (zero-valent sulfur (ZVS), thiosulfate, sulfite, thiocyanate) in the Yellowstone National Park (YNP) hydrothermal springs and ...
