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

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

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.

New research shows that maintaining and adopting proposed marine protected areas (MPAs) in the Southern Ocean could almost ...

New research from the University of Copenhagen suggests that volcanic eruptions during the Ice Age may have triggered sudden climate change by disrupting the Atlantic Meridional Overturning ...

Ten years after the Paris Agreement took effect, newly released climate datasets show the world warming at an accelerating ...

Fresh evidence from sediment cores, satellite records, and deep-ocean sensors is converging on a troubling finding: meltwater ...

But scientists say a warming world is throwing off this balance. As Arctic ice melts, freshwater enters the North Atlantic — making the ocean water less dense, so it is less likely to sink. As a ...
