Jie Deng and Ross Maguire will receive the 2018 Study of the Earth’s Deep Interior Award for Graduate Research at AGU’s Fall Meeting 2018, to be held 10–14 December in Washington, D. C. This award is given annually for advances that contribute to the understanding of the deep interior of the Earth or other planetary bodies using a broad range of observational, experimental, and/or theoretical approaches.

Understanding Electrical Signals from Below Earth’s Surface
A new version of a free Web application (SIGMELTS 2.0) helps Earth scientists interpret electrical anomalies in Earth’s crust and mantle and track the sources of earthquakes and volcanic eruptions.

Carbonate Melting Enhances Mantle CO2 Fluxes in Old Ocean Basins
The amount of CO2 segregated from the mantle by carbonate melting beneath old oceanic crust may equal that emitted along the mid-ocean ridge system, thereby contributing to the global carbon cycle.

Harry W. Green II (1940–2017)
By keenly probing mantle rheology, interactions of deformations and phase transitions, and microscopic features, he made major contributions to petrology, mineralogy, and earthquake science.

Diamond Impurities Reveal Water Deep Within the Mantle
A high-pressure form of ice, trapped within diamonds forged in the lower mantle, suggests that aqueous fluids reside deeper in Earth than we knew.

Widespread Mantle Upwelling Beneath Oceanic Transform Faults
A global characterization of mantle flow patterns beneath active oceanic transforms suggests pervasive upwelling stabilizes divergent plate boundaries by warming and weakening these enigmatic features.

Tracking Deep-Earth Processes from Rapid Topographic Changes
Rapid elevation-rise in Turkey, tracked by marine sediments that now sit at 1.5 km in elevation, is linked to deep-Earth processes that can explain short-lived, extreme rates of topographic change.

Brian Kennett Receives 2017 Inge Lehmann Medal
Brian Kennett was awarded the 2017 Inge Lehmann Medal at the American Geophysical Union Fall Meeting Honors Ceremony, held on 13 December 2017 in New Orleans, La. The medal is for “outstanding contributions to the understanding of the structure, composition, and dynamics of the Earth’s mantle and core.”
