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 ...

Since the Industrial Revolution, scientists estimate that the ocean has become around 30% more acidic from the uptake of ...

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 ...

The Southern Ocean can release stored heat during cooling, creating short-term warming. This discovery shows climate recovery ...

This summer scientists drilled deep below the Atlantic Ocean off the coast of northeastern US and tapped into a huge, mysterious reservoir of freshwater — what they discovered could have big ...

New research shows that marine heat waves can reshape ocean food webs, which in turn can slow the transport of carbon to the deep sea and hamper the ocean's ability to buffer against climate change.

We know next to nothing about 99.999 percent of the seafloor. How one researcher plans to democratize deep-sea exploration. Katy Croff Bell, who has been an ocean researcher for 25 years, is working ...
