Ocean chemistry sustained Earth's oxygen, study finds

Original: How ocean chemistry helped life keep breathing

A new study from researchers at the University of California, Riverside finds that changes in ocean chemistry played a key role in allowing life on Earth to keep producing oxygen over billions of years. The research suggests seawater composition helped regulate the balance of elements that microbes relied on, explaining how Earth's atmosphere stayed breathable through major shifts in the planet's history.

Why now: Freshly published university research on how Earth's oceans kept the atmosphere oxygenated is drawing scientific and public interest.
