Putting some publishing action into deep Earth-surface interactions
Earth’s interior
Variable Mantle Lies Below Ancient Pieces of Earth's Crust
Underneath old and stable pieces of Earth's crust in North America, the mantle's uppermost portion contains multiple layers that change the velocities of seismic waves.
Improved Models of Wind Flow over Mountains
A new approach for representing areas of low-lying mountains improves the simulation of atmospheric flow over gentle topography without increasing computational requirements.
P Wave Amplitude Decay Offers a Glimpse of Earth's Structure
Scientists look at deep earthquake signals to map how seismic waves lose energy in the upper mantle across the United States.
Peter Olson Receives 2015 Inge Lehmann Medal
Peter Olson was awarded the 2015 Inge Lehmann Medal at the American Geophysical Union Fall Meeting Honors Ceremony, held on 16 December 2015 in San Francisco, Calif. The medal is for "outstanding contributions to the understanding of the structure, composition, and dynamics of the Earth's mantle and core."
UAE-Oman Mountains Give Clues to Oceanic Crust and Mantle Rocks
When oceanic plates meet continental plates, the continental plates usually come out on top. Cases where this is reversed provide valuable access to oceanic crust and mantle materials.
Earth's Water Came from Space Dust During Planetary Formation
A new analysis of lava from the deep mantle indicates that water-soaked dust particles, rather than a barrage of icy comets, asteroids, or other bodies, delivered water to the newly forming Earth.
North America Does the Wave (Slowly)
Data-driven modeling helps explain how convection currents in Earth's mantle influence the rise and fall of surface features, but these models are in an early stage.
New Insights into the Composition of Inner Earth
Isotopic signatures in volcanic basalts show that Earth's interior is even less uniform than scientists previously thought.
Liu Receives 2015 Jason Morgan Early Career Award
Lijun Liu will receive the 2015 Jason Morgan Early Career Award at the 2015 American Geophysical Union Fall Meeting, to be held 14–18 December in San Francisco, Calif. The award is for significant early-career contributions in tectonophysics.
