Scientists from the Woods Hole Oceanographic Institution (WHOI) have identified a new type of ocean ridge that is spreading so slowly that Earth's mantle is exposed over large regions of the sea floor ...

Oceanography, Vol. 20, No. 1, SPECIAL ISSUE ON InterRidge (MARCH 2007), pp. 90-101 (12 pages) Aumento, F., and H. Loubat. 1970. The mid-Atlantic ridge near 45°N ...

Sixty-million-year-old rock samples from deep under the ocean have revealed how huge amounts of carbon dioxide are stored for millennia in piles of lava rubble that accumulate on the seafloor. A new ...

Generally speaking, "ridge subduction" involves subduction of spreading oceanic ridges, aseismic ridges or oceanic plateaus and inactive arc ridges, and this common and important geological process ...

THE theory of ocean floor spreading requires that oceanic crust be generated at mid-ocean ridges. Evidence from a variety of sources suggests that the new crust is made largely of basalt and gabbro, ...

A new analysis of rocks thought to be at least 2.5 billion years old by researchers at the Smithsonian's National Museum of Natural History helps clarify the chemical history of Earth's mantle—the ...

Image: Tiny crystals called zircons are used to date oceanic crust. A newly developed method that detects tiny bits of zircon in rock reliably predicts the age of ocean crust more than 99 percent of ...

India's deep-ocean exploration has taken a monumental leap forward with a 15-year agreement to explore for precious metals in ...

Along submarine mountain ranges, the mid-ocean ridges, forces from the Earth's interior push tectonic plates apart, forming new ocean floor and thus moving continents about. However, many features of ...

What's at the bottom of the Mariana Trench, and how do we know? How deep does the ocean go? We'll answer these questions and more in this deep dive into the world's oceans. Come on in: The water's ...
