Humans still haven’t seen 99.999% of the deep seafloor Human eyes have only seen a tiny, tiny, tiny fraction of the areas of the world that are covered by deep water.

In a new study published in Science Advances, researchers reveal that humans have visually documented just 0.001% of the deep seafloor—an area barely larger than Rhode Island. “I knew it was g ...

The surprisingly circular seamount rises about 3,300 feet off the seafloor, and has “relatively steep, smooth sides,” scientists say. Saildrone image A mountain would seem to be a tough thing ...

The crew of the National Oceanic and Atmospheric Administration's Okeanos Explorer vessel caught sight of some weird hole formations on the Atlantic seafloor over the weekend. What caused them?

A whole new world: Surprising ecosystem thriving under sea floor. The study authors found the tubeworms and other species living in warm, fluid-filled cavities more than 2,500 meters, or 1.5 miles ...
