Geologists to Shed Light on the Mantle with 3D Model
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
Using a technique similar to taking a CT scan of Earth, researchers found the possible remnants of a long-debated “missing” tectonic plate.
Earthquake-coda Tomography Boosts Illumination of the Deep Earth
A new tomographic method based on correlations of seemingly chaotic earthquake coda waves yields otherwise unobservable arrivals, thus greatly improving illumination of the deep Earth.
CAT Pictures of Internal Solitary Waves in Indonesian Strait
Huge and rapid subsurface temperature changes associated with propagating internal solitary waves were observed from a moored coastal acoustic tomography (CAT) system in Lombok Strait in Indonesia.
X-Ray Computed Tomography Detects Resolution Scale Gold Grains
A method combining partial-volume and blurring effects can be used to measure small features in computed tomography data volumes.
The Unsolved Mystery of the Earth Blobs
Researchers peering into Earth’s interior found two continent-sized structures that upend our picture of the mantle. What could their existence mean for us back on Earth’s surface?
Donald W. Forsyth Receives 2017 Maurice Ewing Medal
Donald W. Forsyth was awarded the 2017 Maurice Ewing Medal at the American Geophysical Union Fall Meeting Honors Ceremony, held on 13 December 2017 in New Orleans, La. The medal is for “significant original contributions to the ocean sciences.”
Seismological Models Are Biased, but Scientists Have a Solution
Many seismic wave models are based on an erroneous assumption about the Earth's interior. A new technique corrects this by eliminating false signals produced by models.
Novel Technique Finds New Features Under United States
A new high-fidelity tomography harnesses USArray data to expose a wealth of noteworthy crustal and upper mantle structures, including previously unknown anomalies beneath the Appalachians.
