A research team led by University of California, Riverside geoscientists has corroborated evidence that oxygen production began in Earth's oceans at least 100 million years before the Great Oxidation Event (GOE). The researchers analyzed 2.5 billion-year-old black shales, which revealed that episodes of hydrogen sulfide accumulation in the oxygen-free deep ocean occurred nearly 100 million years before the GOE. Scientists have long believed that the early ocean was characterized by high amounts of dissolved iron.
