Advances in mapping lowermost mantle convective flow with seismic anisotropy observations
Convective flow in the deep mantle controls Earth's dynamic evolution, influences plate
tectonics, and has shaped Earth's current surface features. Present and past convection …

Low-velocity heterogeneities redistributed by subducted material in the deepest mantle beneath North America
The origins and composition of seismic low-velocity heterogeneities atop the core-mantle
boundary (CMB) remain poorly understood. It is also debated whether they are static …

ScS shear-wave splitting in the lowermost mantle: Practical challenges and new global measurements
Many regions of the Earth's mantle are seismically anisotropic, including portions of the
lowermost mantle, which may indicate deformation due to convective flow. The splitting of …
