Uniform automated analysis of Sdiff splitting due to lowermost mantle anisotropy: Caveats and curated global dataset
Seismic anisotropy, the dependence of seismic wave speeds on the direction of propagation and/or polarization, places crucial constraints on deformation and convective flow in the lowermost mantle (the D″ layer). Shear waves that diffract along the core-mantle boundary (CMB) are ideally suited for probing this region...
