Micrometer scale investigation of the rheological properties of olivine in pressure and temperature conditions corresponding to the shallow lithosphere.
Earth's interior
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.
A Dive into the Deep Earth
In July, Eos looks at the incredible capabilities scientists have developed to recreate the enormous pressures and temperatures that exist far below the planet’s surface.
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.
Globally Variable Water Content in the Mantle Transition Zone
Using electromagnetic waves originating in the ionosphere and magnetosphere, conductivity profiles reaching the deep upper mantle show surprising variability in water content.
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.
The Other, Deeper, South American Flat Slab
Tomographers trace the slab subducting beneath South America into the lower mantle, providing the most complete picture of structure beneath the continent to date.
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.
