New research from the University of Copenhagen suggests that volcanic eruptions during the Ice Age may have triggered sudden ...

It’s part of the scenario in “The Day After Tomorrow,” but scientists differ over whether or how fast it may occur. A team ...

Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge tectonic theories.

The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...

Climate change is rapidly freshening one of Earth’s saltiest ocean regions in the Southern Indian Ocean, potentially disrupting circulation.

Bigger than any waterfall on land, this hidden ocean giant flows silently beneath the sea, unseen by human eyes, yet it plays a powerful role in shaping Earth's climate and ocean currents.

New research reveals the source of this carbon – and the driving forces behind it – are far more complex than previously ...

At the edge of the Antarctic Peninsula, far from research stations and tourist routes, a small team collected seawater in conditions that are not easi.

A new study suggests that some of the world’s oxygen-deprived oceans could eventually regain higher oxygen levels in the ...

Fresh evidence from sediment cores, satellite records, and deep-ocean sensors is converging on a troubling finding: meltwater pouring off the Antarctic ice sheet may be reorganizing the planet’s ocean ...

Scientists have detected a major drop in salinity in one of the world’s saltiest ocean regions. The change could affect monsoons, marine life and global climate systems, raising new concerns about the ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.
