WebPhotosynthesis-induced enrichment of the Earth’s atmosphere with dioxygen (O 2) led to the Great Oxygenation Event (GOE), or Oxygen Catastrophe. Oxygen began to accumulate once all the oxygen sinks on Earth were saturated. For example, the oxygen oxidized the methane in the early atmosphere to carbon dioxide and the minerals in the rocks were ... WebThe rise of molecular oxygen (O 2) in the atmosphere and oceans was one of the most consequential changes in Earth's history.While most research focuses on the Great Oxidation Event (GOE) near the start of the Proterozoic Eon—after which O 2 became irreversibly greater than 0.1% of the atmosphere—many lines of evidence indicate a …
