Meet the “ghost fish,” a phantom of the abyss. Here’s how we found the first ever proof of its existence just a few years ago. The deep sea is a part of the world that very few humans get the chance ...

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 ...

When the submarine plunged to about 1,500 meters below sea level, ecologist Jeff Drazen asked the pilots to cut the strobe lights that had been guiding them through the pitch-black waters. For a ...

Marine life in the deep ocean can take decades to recover from the impact of deep-sea mining for rare metals, new research shows. A study published in the journal Nature found that the site of a ...

The Trump administration announced this past week that it has entered talks with the Cook Islands to research and develop seabed mineral resources. The Polynesian archipelago is one of only a handful ...

The deep sea is a distinctive environment, distinguished from surface waters by darkness, cold and immense pressures. Global data reveal how much more connected deep-sea life is than life in the ...

Workers disembark from a research vessel that returned from the Clarion Clipperton Zone of the Pacific Ocean, where soil, water, and wildlife samples were obtained from deep in the ocean as part of ...

A world-first study led by Museums Victoria Research Institute has revealed that beneath the cold, dark, pressurized world of the deep sea, marine life is far more globally connected than previously ...

The deep sea, the planet’s most expansive and least understood ecosystem, remains largely unexplored. Yet while the deep sea may seem a dark and distant space, events underwater directly impact our ...

The ocean abundant with undiscovered resources is an important frontier for humanity’s exploration of the Earth. As the pressure on global supply and demands increases, deep-sea research and ...
