Challenger Deep, the lowest point in the deepest canyon on Earth, lies 35,876 feet below sea level at the southwestern extreme of the Mariana Trench (6.8 miles, or 10.9 kilometers).

An internet user (@leafloaf5054) expressed, “That's so deep. Also, it's crazy how deep the ocean is.” Lauding the chilling simulation video, a commenter (@GouriSundaresh) said, “The ...

Now, oceanographer Katherine Bell and her collaborators have quantified just how little of the deep sea floor scientists have visually observed: less than 0.001%, an area equivalent to about one ...

Scientists have mapped almost every Martian crater but only about 20% of the seabed. Yet interest in the ocean is growing. A trio of new books plunges into the deep.

But now, a new innovation called deep-sea reverse osmosis (DSRO) is rewriting the rules. By harnessing the immense natural pressure found at ocean depths, this technology offers a more sustainable ...

Unsurprisingly, most direct observations of the deep sea occurred in the waters around wealthy countries with the capability to conduct them—especially the U.S., Japan and New Zealand.

Geologist and deep sea expert Jeffrey Karson of Syracuse University, who wasn't part of this research team, says this is the first time he's ever seen a well-documented number that really ...

In a recent study published in Science, researchers took the deepest look yet at how cells have adapted to life in the abyss. In 2018, Budin met Steve Haddock, a deep-sea biologist, and they ...

“It’s a paradox. The deep sea is highly connected, but also incredibly fragile,” said Dr. O’Hara. “Understanding how life is distributed and moves through this vast environment is essential if we want ...

For us land-dwellers, being crushed under several miles of ocean water wouldn’t end very well. But for a deep-sea dwelling ctenophore, also known as a comb jelly, being brought up to the surface ...
