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.
Pearson and Reid Receive 2019 Norman L. Bowen Awards
Graham Pearson and Mary R. Reid received the 2019 Norman L. Bowen Award at AGU’s Fall Meeting 2019, held 9–13 December in San Francisco, Calif. The award recognizes “outstanding contributions to the fields of volcanology, geochemistry, and petrology.”
Unexpected Oceanic Lithosphere-Asthenosphere P-wave Velocities
A peak in seismic P-wave – S-wave velocity ratios at the lithosphere-asthenosphere boundary beneath old Pacific lithosphere requires an additional property besides temperature as an explanation.
Orson Anderson (1924–2019)
This pioneer in the field of mineral physics contributed mightily to our understanding of mineral properties at high temperatures and high pressures and of Earth’s interior.
Modeling Fluid Migration in Subduction Zones
Scientists from different disciplines are working together to identify common challenges in and techniques for modeling fluid migration associated with subduction zone processes.
Visualizing the Deep Carbon Cycle
Geoscientists have created animations to help visualize different components of Earth’s carbon cycle.
Search for MH370 Revealed Ocean Crust Waves
Efforts to recover the missing airplane produced high-resolution bathymetry of the southern Indian Ocean that raises new ideas about how ocean crust forms.
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.
Microbial Influences on Subduction Zone Carbon Cycling
An innovative collaboration is investigating how geobiological processes alter fluxes of carbon and other materials between the deep Earth and the surface.
