The changes in ocean chemistry were gradual. The Archaean period lasted 1.5 billion years. This is more than half of Earth’s ...

Rivers, streams, lakes, and reservoirs aren't just scenic parts of our landscape—they're also vital engines for life on Earth ...

Scattered across an abyssal plain known as the Clarion-Clipperton Zone (CCZ) are polymetallic nodules that are a potato-sized ...

Scientists assumed most forms of life before the Great Oxidation Event didn't metabolize oxygen—but recent research suggests ...

Bacteria used oxygen far earlier than expected, reshaping views on early life, evolution, and photosynthesis origins.

The model tracks the oxygen "turnover" — how much oxygen is produced and consumed — in inland waters since 1900. The ...

But while lifeless during that time, the planet was already covered by vast oceans dotted with hydrothermal vent systems that ...

This phosphorus fed photosynthesizing microbes, which produced oxygen as a byproduct. “Activity of microorganisms in the ocean played a central role in the evolution of atmospheric oxygen.

“Activity of microorganisms in the ocean played a central role in the evolution of atmospheric oxygen. However, we think this would not have immediately led to atmospheric oxygenation because ...

Current warming accounts for up to 55 percent of the decrease in lake oxygen levels, the researchers estimate. If this trend ...

Rivers, streams, lakes, and reservoirs aren't just scenic parts of our landscape -- they're also vital engines for life on Earth. These inland waters 'breathe' oxygen, just like we do. But a new study ...
