  • Biological regulation of atmospheric chemistry en route to planetary oxygenation 

    Izon, Gareth; Zerkle, Aubrey L.; Williford, Kenneth; Farquhar, James; Poulton, Simon; Claire, Mark W. (2017-03-28) - Journal article
    Emerging evidence suggests that atmospheric oxygen may have varied before rising irreversibly ∼2.4 billion years ago, during the Great Oxidation Event (GOE). Significantly, however, pre-GOE atmospheric aberrations toward ...
  • Multiple oscillations in Neoarchaean atmospheric chemistry 

    Izon, Gareth; Zerkle, Aubrey Lea; Zhelezinskaya, Yadviga; Farquhar, James; Newton, Robert J.; Poulton, Simon W.; Eigenbrode, Jennifer L.; Claire, Mark (2015-12-01) - Journal article
    The Great Oxidation Event (GOE) represents a crucial juncture in Earth history, signifying the rise in atmospheric oxygen from parts per million to per cent levels at ~2.45-2.32 billion-years-ago (Ga). Although planetary ...
