Normal mode sensitivity to Earth's D″ layer and topography on the core-mantle boundary: What we can and cannot see

Abstract:

The core-mantle boundary (CMB) is Earth's most profound internal boundary separating the liquid iron outer core and the solid silicate mantle. The detailed structure near the CMB has a major influence on mantle convection and the evolution of the core. Seismic observations, such as topography on the CMB, thin ultra-low velocity zones (ULVZs), seismic anisotropy and the anticorrelation between shear wave and bulk sound velocity heterogeneities have mainly been made using body waves and are sti...
