Explorers know that the Earth’s oceans are vast, covering about 71% of the surface of the globe. According to a new study, just 0.001% of the deep seafloor has been visually observed. The deep ocean ...

I spent years preparing to dive into the deepest place on earth. Only a handful of people have traveled into the depths of the Mariana Trench, nearly 7 miles below the ocean surface. As a geologist ...

Ocean Discovery League (ODL) has launched the Global Deep Sea Exploration Goals, an ambitious international effort to visually explore 10,000 strategically selected locations across the deep seafloor.

The deep sea is awfully cryptic. But scientists are making it less so. A recent marine expedition to remote, previously unknown ocean caverns over 8,200 feet down revealed life thriving underneath ...

(Saunderstown, RI — May 7, 2025) In a groundbreaking study published today in Science Advances, researchers from Ocean Discovery League reveal that only a minuscule fraction of the deep seafloor has ...

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 international team of researchers, including a Northwestern University chemist, has discovered that metallic minerals on the deep-ocean floor produce oxygen—13,000 feet below the surface. The ...

A new study could change the way scientists view microbial processes in the deep ocean. The unexpected findings expand our understanding of the impacts of climate change, including how and where the ...

New data confirms what climate experts have long worried about: a warm mass of deep polar water has expanded toward Antarctica.

In a step toward better understanding how the ocean sequesters carbon, new findings from UC Santa Barbara researchers and collaborators challenge the current view of how carbon dioxide is “fixed” in ...
