Effect of Velocity Anisotropy in Shale on the Acoustic Emission Events Matching and Location
Frontiers in Earth Science, 2022 Accurate source event location is important in fracturing monitoring and characterization. Velocity anisotropy has a great influence on both events matching and events location. Failure to take into account the velocity anisotropy can lead to huge errors

Transfer learning for self-supervised, blind-spot seismic denoising
Frontiers in Earth Science, 2022 Noise is ever present in seismic data and arises from numerous sources and is continually evolving, both spatially and temporally. The use of supervised deep learning procedures for denoising of seismic datasets often results in poor performance: this is

The origin of deep ocean microseisms in the North Atlantic Ocean [PDF]
, 2008 Oceanic microseisms are small oscillations of the ground, in the frequency range of 0.05–0.3 Hz, associated with the occurrence of energetic ocean waves of half the corresponding frequency.
