Marine researchers exploring extreme depths say they have discovered an astonishing deep-sea ecosystem of chemosynthetic life that’s fueled by gases escaping from fractures in the ocean bed. The ...

An underwater voyage has revealed a network of creatures thriving at the bottom of deep-sea ocean trenches, researchers said in a newly published paper. The deep-sea trenches, also called Hadal ...

No matter where you go on the planet, life seems to find a way to survive, even six miles below the surface of the ocean without any sunlight.

Strange organisms that get their energy from chemical reactions instead of the sun have been discovered at the bottom of ocean trenches up to 31,000 feet deep in the northwest Pacific between Russia ...

The average depth of the ocean is around 12,080 feet. While there are vessels of all sizes, even some of the largest anchor and chain systems, like those found on carriers, only stretch to around ...

Deep beneath the ocean's surface, a groundbreaking DNA study reveals that the deep sea is far more globally connected than once thought. By analyzing thousands of brittle stars preserved in museum ...

A human-occupied vehicle (HOV) probing the deep Pacific Ocean has cast a light upon a massive undersea 'metropolis'. The tortuous system of deep craters and dolomite walls blows the Atlantic Ocean's ...

Rising deep-ocean oxygen levels likely opened up new marine habitats and spurred speciation among early vertebrates, according to a new study in the Proceedings of the National Academy of Sciences.

A push to extract minerals from the depths of the Pacific Ocean is gaining momentum. Here is how it works and why it has become a global flashpoint.
