Recent seismological work has revealed new structures in the boundary layer between the
Earth's core and mantle that are altering and expanding perspectives of the role this region …

Much progress has been made over the past several decades in delineating the structure of
subducting slabs, but several key aspects of their dynamics remain poorly constrained …

55 4.4 Experimental techniques 57 4.5 Some general trends in elasticity: Birch's law 59 4.6 …

Observations of seismic anisotropy yield some of the most direct constraints available on
both past and present-day deformation in the Earth's mantle. Insight into the character of …

Measurements of the splitting or birefringence of seismic shear waves that have passed
through the Earth's mantle yield constraints on the strength and geometry of elastic …

The subduction of oceanic lithosphere into the Earth's deep interior is thought to drive
convection and create chemical heterogeneity in the mantle. The oceanic lithosphere as a …

The anisotropic single crystal seismic properties are reviewed in the light of recent
experimental and theoretical determinations. Although considerable progress has been …

Strong heterogeneity at a variety of scale lengths has been imaged in the lowermost mantle
using different forward and inverse methods. Coherent patterns in differential travel times of …

The existence, spatial distribution, and style of volcanism on terrestrial planets is an
expression of their internal dynamics and evolution. On Earth a physical link has been …

We compile and make publicly available a global digital database of body wave
observations of seismic anisotropy in the D′′ layer, grouped using the method used to …
