A revised lower estimate of ozone columns during Earth’s oxygenated history [PDF]

Royal Society Open Science, 2021
The history of molecular oxygen (O2) in Earth’s atmosphere is still debated; however, geological evidence supports at least two major episodes where O2 increased by an order of magnitude or more: the Great Oxidation Event (GOE) and the Neoproterozoic ...
