Maps created with tools like sonar can show the shape of the seafloor, but it's much harder to send cameras down beyond 200 meters, or more than 656 feet, where sunlight begins to fade rapidly and ...

Making matters worse, nearly two-thirds of all visual seafloor observations have taken place within 200 nautical miles of just three nations: the U.S., Japan, and New Zealand.

Of central concern are the plumes of sediment that mining would create, both at the seafloor and at depths around 1,000 meters, which have “some of the clearest ocean waters,” said Jeffrey ...

The more than half mile long wall, called the Blinkerwall, was likely used by Stone Age hunter-gatherers to herd reindeer toward a shooting blind.

Mah argues that not every survey needs sub-meter accuracy, but that many operations on the seafloor would benefit from faster mapping. Offshore wind developers might pay for a sub-meter survey up ...

Scientists probing the bottom of the Pacific Ocean made a surprising discovery: animals living underneath the seafloor in an area with volcanic activity. Giant tubeworms, which are known as the ...

Giant worms appear to be breeding beneath the seafloor at hydrothermal vents in the eastern Pacific, near the Galápagos Islands, new research shows.
