Study Reveals Humans Have Directly Observed Less Than 0.001% of the Deep Seafloor

Humans Have Seen Only 0.001 Percent of the World's Deep Seas, Leaving Most of the Planet a Vast Mystery

Researchers argue that expanding deep-sea exploration is vital to understanding and managing these marine habitats

Humans have seen a tiny fraction of the deep sea. Researchers are trying to change that

The deep sea covers about two-thirds of the Earth’s surface, but according to a new study, humans are estimated to have observed less than .001 percent of the deep seafloor — an area roughly the size of Rhode Island. Stephanie Sy speaks with the study’s author, Katy Croff Bell, who is working to change that.

A scientific investigation examined more than 44,000 dives registered since 1958 and concluded that only a minimal fraction of the underwater land has been observed directly

New study says more than 99% of the deep sea is still a mystery

Researchers claim we know about less than 1% of our deep seas here on Earth, raising concerns over possible deep sea mining.
