For most of deep time, spreading ridges released more carbon than volcano chains, changing how we interpret Earth’s climate history.

WASHINGTON—A new global analysis of the last 19 million years of seafloor spreading rates found they have been slowing down. Geologists want to know why the seafloor is getting sluggish. New oceanic ...

A deep-sea mining test shows ecosystem damage can begin immediately, with more than one-third of seafloor animals lost in a single pass.

The global mid-ocean ridge, with a total length over 65,000 km, is the longest volcanic chain on Earth. Hot magmas are extracted from the upwelling asthenosphere beneath the ridge axis to produce ...

In 1963, Fred Vine, Drummond Matthews, and others found that the crust surrounding the midocean ridges showed alternating bands -- each band magnetized with a polarity opposite the surrounding bands.

Dalton et al. home in on a period from 15 million to 6 million years ago, over which, as prior research revealed, ocean crust production dropped by 35%. This reduction, mostly resulting from a global ...
