A New Understanding of the Mid-Atlantic Ridge and Plate Tectonics

by Jackie Rocheleau 8 March 2021

The first seismic data obtained directly from the Mid-Atlantic Ridge suggest that upwelling may contribute to seafloor spreading.

Subduction May Recycle Less Water Than Thought

by Sarah Stanley 12 February 2021

A new analysis of seismic data from the Middle America Trench suggests that previous calculations have vastly overestimated the total amount of water transported to the mantle worldwide.

Geologists to Shed Light on the Mantle with 3D Model

by E. Gribkoff 4 December 202029 September 2021

The model, which will incorporate 227 million surface wave measurements, could help with everything from earthquake characterization to neutrino geosciences.

The Resurrection Plate Is Dead, Long Live the Resurrection Plate

by Rachel Fritts 16 November 202029 September 2021

Using a technique similar to taking a CT scan of Earth, researchers found the possible remnants of a long-debated “missing” tectonic plate.

What Lies Deep in the Mantle Below?

by G. R. Foulger, G. F. Panza, I. M. Artemieva, I. D. Bastow, F. Cammarano, C. Doglioni, J. R. Evans, W. B. Hamilton, B. R. Julian, M. Lustrino, H. Thybo and T. B. Yanovskaya 25 August 201528 September 2021

For decades, scientists have probed Earth's remote mantle by analyzing how seismic waves of distant earthquakes pass through it. But we are still challenged by the technique's limitations.
