Gwyn will present recent results on Mo isotopes across Ocean Anoxic Events, "Evaluation of the Mo isotope paleoredox proxy in Late Cretaceous ocean sediments."

Laura will give two talks, "Toward multi-element isotopic biosignatures: experimental investigation of microbial metal assimilation", "Temperature dependence of Mo isotope fractionation during adsorption to d-MnO2: implications for the paleoredox proxy."

Although he is not going to Australia, Ariel is co-convening a session with Tom Bullen on heavy stable isotopes.

Members of our group are also co-authors on a paper from our collegues at UC Riverside, "The isotopic expression of Fe shuttling in modern and ancient euxinic sediments: implications for the rise of oxygen."
