Balancing Redox Budgets: Mechanisms for Prolonging Anoxia During Major Carbon Burial Events Open

Sean M. Newby, Seth A. Young, Theodore R. Them, Benjamin C. Gill, Jeremy D. Owens · 2025

Widespread marine anoxic events occurred throughout the Phanerozoic, most notably the Mesozoic oceanic anoxic events (OAEs). They were likely the result of major climatic perturbations that resulted in the burial of significant quantities …

Oxygenation of the Baltoscandian shelf linked to Ordovician biodiversification Open

Anders Lindskog, Seth A. Young, Chelsie N. Bowman, Nevin P. Kozik, Sean M. Newby , et al. · 2023

Marine biodiversity increased markedly during the Ordovician Period (~487–443 million years ago). Some intervals within the Ordovician were associated with unusually rapid and prominent rises in taxonomic richness, the reasons for which re…

Rapid marine oxygen variability: Driver of the Late Ordovician mass extinction Open

Nevin P. Kozik, Seth A. Young, Sean M. Newby, Mu Liu, Daizhao Chen , et al. · 2022

The timing and connections between global cooling, marine redox conditions, and biotic turnover are underconstrained for the Late Ordovician. The second most severe mass extinction occurred at the end of the Ordovician period, resulting in…

Chemical and isotopic evolution of flowback fluids from the Utica Gas Shale Play, Eastern Ohio USA Open

Susan A. Welch, Julia M. Sheets, Elsa Saelans, Matthew R. Saltzman, Sean M. Newby , et al. · 2022

Balancing the redox budgets of Oceanic Anoxic Events Open

Sean M. Newby, Seth A. Young, Theodore R. Them, Benjamin C. Gill, Jeremy D. Owens · 2022

Spatiotemporal redox variability enveloping an Oceanic Anoxic Event Open

Jeremy D. Owens, Sean M. Newby, Siqi Li, Theodore R. Them, Greta Bonacina , et al. · 2022

Understanding and constraining redox conditions surrounding "Oceanic Anoxic Events" (OAEs), as they represent recent intervals of major climate upheaval, are of significant interest as they provide insight into the cascade of events and ti…

Fingerprinting subtle redox fluctuations using vanadium isotopes Open

Siqi Li, Silke Severmann, Sean M. Newby, James McManus, Jeremy D. Owens · 2022

New constraints on mid-Proterozoic ocean redox from stable thallium isotope systematics of black shales Open

Zijian Li, Devon B. Cole, Sean M. Newby, Jeremy D. Owens, Brian Kendall , et al. · 2021

Thallium behavior during high-pressure metamorphism in the Western Alps, Europe Open

Shelby Rader, Richard M. Gaschnig, Sean M. Newby, Gray E. Bebout, Michael Mirakian , et al. · 2021

The Cretaceous Oceanic Anoxic Events: New Geochemical Data from the Central Atlantic Ocean Open

Greta Bonacina, Elisabetta Previde Massara, Paolo Scotti, P. Viaggi, Andrea Piva , et al. · 2020

The Effects of Iron and Manganese Shuttles on Thallium and Vanadium Isotopes in Black Sea Sediments Open

Xinming Chen, Siqi Li, Sean M. Newby, Timothy W. Lyons, Jeremy D. Owens · 2020

Seawater 87Sr/86Sr Stratigraphy of the Middle Ordovician in Central Virginia Open

Sean M. Newby · 2017

Throughout most of the past century, the correlation of strata in a region has mainly been defined through biostratigraphy, the dating of rock through fossil succession. However, work over the past several decades has put increasing emphas…
