  • Large mass-independent oxygen isotope fractionations in mid-Proterozoic sediments: Evidence for a low-oxygen atmosphere?

    Planavsky, Noah J.; Reinhard, Christopher T.; Isson, Terry T.; Ozaki, Kazumi; Crockford, Peter W. (Mary Ann LIebert, 2020)
    Earth's ocean-atmosphere system has undergone a dramatic but protracted increase in oxygen (O₂) abundance. This environmental transition ultimately paved the way for the rise of multicellular life and provides a blueprint ...
  • Marine siliceous ecosystem decline led to sustained anomalous Early Triassic warmth.

    Isson, Terry T.; Zhang, Shuang; Lau, Kimberly V.; Rauzi, Sofia; Tosca, Nicholas J.; Penman, Donald E.; Planavsky, Noah J. (2022-06-18)
    In the wake of rapid CO₂ release tied to the emplacement of the Siberian Traps, elevated temperatures were maintained for over five million years during the end-Permian biotic crisis. This protracted recovery defies our ...
