How little of the deep seafloor humans have ever seen

Season 2025 Episode 130 | 5m 15s

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.
