Deep beneath the ocean's surface lies Earth's largest carbon reservoir: marine sediments that have accumulated organic matter over millions of years. Long assumed to be permanently "locked away," this ...

South African diamonds have revealed nickel-rich metallic inclusions, offering the first direct evidence of reactions predicted to occur deep in Earth’s mantle. The study shows how oxidized melts ...

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

Earth's inner core may be layered like an onion, with silicon and carbon creating distinct zones that explain seismic wave ...

For years, scientists believed that changes in the Earth's interior, such as volcanic eruptions and tectonic plate collisions, primarily affected the surface environment. Events such as the mass ...

Scientists have discovered a new phylum of microbes in the Earth's Critical Zone, an area of deep soil that restores water quality. Ground water, which becomes drinking water, passes through where ...

Scientists discovered deep Arctic methane mounds that release gas, shape ecosystems, and inform climate risks.
