News From the Field A New Wrinkle in Ancient Ocean Chemistry
October 29, 2009 A research team led by University of
California, Riverside, geoscientists has corroborated evidence
that oxygen production began in the 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. University of California, Riverside See also: NSF News
