Universitas Scientiarum, 2019 The estimation of static corrections is an issue still unsolved for PS converted wave processing. Due to the PS converted wave usually arriving at the surface at non-zero angles, the surface consistent approach is no longer valid, and corrections ...

Improving Surface Wave Retrieval From Traffic Noise by Deconvolution of the Decomposed Wavefield
Earth and Space Science, 2023 Traffic noise is an important type of passive seismic data because it usually includes strong dispersive surface wave components and can be easily accessed.

Passive seismic imaging of the Lower Palaeozoic in the Sudret area of Gotland, Sweden [PDF]
Solid EarthPassive seismic data were acquired together with active seismic data along a 2.8 km long profile in the Sudret area of Gotland, Sweden, as part of a feasibility study for storage of CO2 below the Baltic Sea. Seismic interferometry using cross-correlation

Continuous isolated noise sources induce repeating waves in the coda of ambient noise correlations
Seismica, 2023 Continuous excitation of isolated noise sources leads to repeating wave arrivals in cross correlations of ambient seismic noise, including throughout their coda. These waves propagate from the isolated sources.

Estimating the critical angle of top near‐surface layers on the Moon
Near Surface Geophysics, EarlyView.Abstract Near‐surface characterization of the lunar subsurface is essential for future exploration and infrastructure development, particularly for the construction of underground habitats that provide protection against radiation and micrometeorites. However, conventional seismic approaches for estimating subsurface properties typically rely on prior ...

Supervirtual Seismic Interferometry with Adaptive Weights to Suppress Scattered Wave
Applied SciencesLand seismic data are always contaminated by surface waves, which demonstrate strong energy, low velocity, and long vibrations. Such noises often mask deep effective reflections, seriously reducing the data’s signal-to-noise ratio while limiting the ...

Near Surface Geophysics, EarlyView.Abstract The United Kingdom's shallow aquifers offer significant but underdeveloped geothermal energy resource. Seismic methods can help address this by improving the understanding of aquifer heterogeneity and potentially allowing long‐term monitoring of thermal plumes.

Seismic noise in crystal neutron interferometry
Journal of Applied CrystallographyWe are involved in designing, constructing and operating a split-crystal interferometer that uses X-rays and neutrons simultaneously. Neutron interferometers are sensitive to seismic and acoustic noise due to the low speed, low flux and long detection time of thermal neutrons.

Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser
Journal of Synchrotron Radiation, EarlyView.We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...
