The Ontong Java Plateau, a volcanically-formed underwater plateau located in the Pacific Ocean north of the Solomon Islands, is younger and its eruption was more protracted than previously thought, ...

Mass extinction events throughout Earth’s history are characterized as significant disruptions to life on the planet. There have been five major extinction events that have fundamentally changed how ...

A vast, geometric feature buried beneath the Pacific Ocean is forcing scientists to rethink what they know about Earth’s deep past. Early mapping suggests a colossal, plateau-like structure near ...

Geology textbooks describe the Earth's mantle beneath its plates as a well-mixed viscous rock that moves along with those plates like a conveyor belt. But that idea, first set out some 100 years ago, ...

Schematic illustration of the oceanic plate beneath the Ontong Java Plateau inferred from seismic wave analyses. High-frequency seismic observations indicate that the plate has a composite structure ...

Part of an undersea plateau about 750 miles off the coast of Brazil was once a tropical island above the ocean. This submerged island is rich in ferromanganese crusts, which contain valuable elements ...
