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

Oxygen-producing rocks have been found on the deep seafloor, challenging what we know about oxygen production. I don’t know about you, but when I learned about oxygen production, it involved plants, ...

Rocks are generating 'dark oxygen' in an area being explored for deep-sea mining. Over 12,000 feet below the surface of the sea, in a region of the Pacific Ocean known as the Clarion-Clipperton Zone ...

I recently participated in a three-week-long, National Science Foundation-funded research cruise to the Mariana Trench. Our target was an east-to-west transect starting near Guam, over the Challenger ...

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

Nearly 4,000 m beneath the Pacific, in water so dark that sunlight has never penetrated, scientists have stumbled on a new ...

From Earth’s oldest rocks to glowing swamp lights and hidden ocean life, scientists in 2025 uncovered clues beneath our feet ...

Clare Fieseler's and Jason Jaacks' reporting was supported by a grant from the Pulitzer Center and co-published with the Post and Courier. Rachel Feltman: For Scientific American’s Science Quickly, ...

Mining the deep oceans for cobalt, nickel, rare earths and other metals could accelerate the world’s conversion to renewable power sources. These minerals are hard to obtain on land, where mining has ...

An ambitious plan to harvest metals-rich nodules from the abyssal seafloor of the Pacific Ocean will be in the spotlight next week as the International Seabed Authority (ISA) meets in Kingston, ...

The push for greener energy has led to a rising demand for batteries, which in turn has amplified the need for metals like nickel, cobalt, and manganese. Earlier, these metals have been sourced from ...
