This was great work with a complex dataset that will need more work to fully understand and interpret this setting. Click here for an open access link for 50 days.
02/25/2019 – Congrat to Seth Young and his graduate student's new manuscript is now out in Earth and Planetary Sciences which assess the local and global redox state of the ocean during the Iriviken positive carbon isotope excursion using I/Ca and carbonate-associated-sulfur isotoes from two carbon sections. This is just the begining of the papers that constrain the Paleozoic redox conditions. Click here for an open access link for 50 days.
02/25/2019 – I am excited to announce that a new manuscript is now out in Nature Geoscience that was lead by Chadlin Ostrander which analyzed an Archean core for Tl and Mo isotopes. In combination these two systems suggest Mn oxides were buried in the oceans which requires oxygenated sediments to precipitate and permanently bury Mn oxides. This is new evidence for more widespread oxygen conditions but still limited in the early ocean.Click here for an open access link.
02/13/2019 – A new manuscript is now out in Earth and Planetary Letters that was lead by Morgan Raven which analyzed organic sulfur isotopes from several localities during OAE-2 and discusses the implications for ocean chemistry and redox condtions. Click here for an open access link for 50 days.
12/24/2018 – A new manuscript is now out in Earth and Planetary Letters that documents and compiles mercury enrichments during the T-OAE.

10/07/2018 – Congrats to Fei Wu on leading a new manuscript published that for the first time investigates the vanadium isotopes of seawater using a new method in Geochimica et Cosmochimica Acta. This work was long overdue and took many people working on this to optimize the method which we hope to refine with future work. Our work suggests that the isotopic composition of the ocean is homogenous but more detailed research is required. Click here is an open access link for 50 days.

08/01/2018 – Today a new Earth and Plantary Science Letters publication is out which utilizes two methods, forward isotope modeling and ArcGIS mass accumulation rates, to evaluate the amount of organic carbon burial during OAE-2. While OAE-2 is our one of our best samples events we still only can reasonably extrapolate to ~13% of the seafloor and with many assumptions cannot account for the entire amount of carbon burial required for the carbon isotope excursion.
06/14/2018 – Today our Proceedings of the National Academy of Sciences publication on the relationship between volcanism, extinction and ocean deoxygenation during ther early Toarcian was published.
