A recent study published in Geology describes the first ever comprehensive digital map of our seafloor’s sediment composition, which covers 70 percent of the planet’s surface.

Drone ships, deep-sea robots, and better sonar are finding unknown seafloor habitats as well as volcanoes, faults, and tsunami-triggering slopes.

A new digital map of the composition of the seafloor reveals "microfossil" graveyards off the coast of Australia, as well as other complex deep-ocean geology.

The New Seafloor Map That Could Help Find Flight MH370 The surface of Mars has been mapped in greater detail than most of Earth’s seafloor.

It’s part of a long-term effort, funded by governments and nonprofits around the world, to map the entire seafloor for the first time. And it’s got major global economic implications.

This is the Earth's seafloor seen as never before, and it took scientists some smart work with gravity to get it. The new images, shown above and in zoomable formats below, are two- to four-times ...

To construct the map, Adriana Dutkiewicz and her colleagues at the University of Sydney analyzed the composition of nearly 15,000 seafloor samples, taken over half a century by research ships. The ...

Scientists have mapped less than 25% of the world's seafloor. Experts say that getting that number up to 100% would improve everything from tsunami warnings to the Internet and renewable energy ...

Freezing cold and ringed with treacherous ice, the Arctic isn’t exactly hospitable territory for boats. As a result, maps of the Arctic seafloor aren’t as detailed as they should be. But that ...

Mapping the ocean floor has never been easy, but new satellite data brings the topography of the seafloor to life.

A global map of the ocean floor could buoy the economy Researchers have mapped a quarter of it so far. Communications, shipping, mining and climate modeling could benefit.
