US EditionStudy Reveals Humans Have Directly Observed Less Than 0.001% of the Deep Seafloor
- Only a small fraction of the deep seafloor has been imaged, with less than 0.001% observed, according to researchers from the Ocean Discovery League in a study published in Science Advances.
- The deep ocean, covering 66% of Earth's surface, remains largely unexplored, despite decades of deep-sea exploration.
- Five countries – the United States, Japan, New Zealand, France, and Germany – account for 97% of all deep-sea submergence observations, due to high ocean exploration costs.
- Limited exploration of the deep ocean poses critical problems for science and policy amidst accelerated threats like climate change and potential resource exploitation.

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.
Guess How Much of the Ocean Floor Humans Have Explored. Now Try Again. - WhoWhatWhy
Guess How Much of the Ocean Floor Humans Have Explored. Now Try Again. (Maria) The author writes, “It is a common refrain that we know more about the surface of Mars than the bottom of the oceans. Now, oceanographer Katherine Bell and her collaborators have quantified just how little of the deep seafloor scientists have actually explored: less than 0.001%, an area equivalent to about one-tenth the size of Belgium. The findings were published on …
