This map shows the locations of deep-sea dives carried out between 1958 and 2024. Expeditions have focused on a small number of places, mainly around the United States, 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 ...

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 ...

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 ...

Cue outrage from environmentalists keen to protect the unique organisms that live in the CCZ at almost any cost. They observe that the deep sea is one of the last places on the planet not yet ...
