The Great Oxygenation Event (GOE), also called the Oxygen Catastrophe, Oxygen Crisis, Oxygen Holocaust, Oxygen Revolution, or Great Oxidation, was the biologically induced appearance of dioxygen (O 2) in Earth's atmosphere.he gap between the start of oxygen production from photosynthetic organisms and the geologically rapid increase in atmospheric oxygen (about 2.5â2.4 billion years ago) may have been as long as 900 million years.
Table 7a-1 lists the eleven most abundant gases found in the Earth's lower atmosphere by volume. Of the gases listed, nitrogen, oxygen, water vapor, carbon dioxide, methane, nitrous oxide, and ozone are extremely important to the health of the Earth's biosphere.The table indicates that nitrogen and oxygen are the main components of the atmosphere by volume.Together these two gases make up approximately 99% of the dry atmosphere. Both of these gases have very important associations with life.he table indicates that nitrogen and oxygen are the main components of the atmosphere by volume.
