Seismic interference noise attenuation
SEG Technical Program Expanded Abstracts 2004, 2004Summary Attenuation of seismic interference noise that overpowers seismic reflections can be achieved by making use of wellknown f-x prediction filters and the non-predictability of interfering noise from shot to shot.

Information from Seismic Noise
Science, 2005Contrary to intuition, noise can contain useful information. In his Perspective, [Weaver][1] highlights the report by [ Shapiro et al .][2], who show that noisy seismic wave fields can be used to extract information about the Earth's crust. Despite their random appearance, the wave fields retain a residual coherence, which distributes their energy in ...

Seismic interferometry—turning noise into signal
The Leading Edge, 2006Turning noise into useful data—every geophysicist's dream? And now it seems possible. The field of seismic interferometry has at its foundation a shift in the way we think about the parts of the signal that are currently filtered out of most analyses—complicated seismic codas (the multiply scattered parts of seismic waveforms) and background noise ...

Bulletin of the Seismological Society of America, 1967
abstract This report consists of a summary of the studies conducted on the subject of short-period (6.0-0.3 sec period) noise over a period of approximately three years. Information from deep-hole and surface arrays was used in an attempt to determine the types of waves of which the noise is composed.

Seismic noise and gravity-gradient noise
2019Gravity gradient noise is generated by mass density changes through fluctuating gravity fields. Ambient seismic noise generated by microseismism, wind or of antropogenic origin is a possible source of such fluctuations. This work gives an overview of the impact of seismic noise and gravity-gradient noise on existing gravitational-wave detectors, and ...

GEOPHYSICS, 1968
Seismic noise has been measured in deep wells by the Geotechnical Corporation at twelve different locations and by the Shell Development Company at three deep wells. To explain the power attenuation and the coherence between vertically separated seismometers, one requires noise vibrations taken as a mixture of propagation modes, possibly surface‐wave ...

Seismic noise discrete filtering
pure and applied geophysics, 1968By using the power density spectra of the seismic signal and the noise, it is possible to design a transfer function of an optimum (in Wiener sense) linear filter. The corresponding impulsetransfer functions dealt with in the paper were calculated as the approximation of the continuous transfer functions. This transformation can be done e.g.
