The core-mantle boundary region under the Gulf of Alaska : no ULVZ for shear waves

, 2000
The Earth's core-mantle boundary (CMB) marks the boundary between the hot, molten iron core and the silicate mantle and is a thermal, chemical, and flow boundary. Previous observations of very slow compressional wavespeeds suggest that thin ultra-low-velocity zones (ULVZs), possibly composed of a mixture of molten iron and silicates, exist at the base ...

Denoising teleseismic data for deep Earth studies using a supervised deep-learning auto-encoder: a case study of diffracted waves from ULVZs

Seismic noise, particularly the microseism generated by the oceans, is a fundamental limitation on using short period (1 - 10 s) teleseismic data to study the deep Earth. Deep learning auto-encoders have proven effective at denoising seismic data in other applications.
