Obtencao e interpretacao de dados de Reflexao Sismica Superficial (Rasa) - exemplos e aplicacoes
(1990-12-01)
Successful application of shallow seismic reflection method is related directly to the ability of the ground to transmit high-frequency seismic energy from a seismic source. The dominant frequencies of reflection data are ...

SVD filtering applied to ground-roll attenuation
(2010)
We present a singular value decomposition (SVD) filtering method for attenuation of the
ground roll. Before the SVD computation, normal move-out (NMO) correction is applied to the seismograms, with the purpose of flattening ...
Adaptive seismic ground roll attenuation using the double density dual tree discrete wavelet transform (dwt) method
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2012)
Seismologists working on the reflection of seismic data have been dealing with noise and trying to attenuate noise as much as possible without damaging a particular signal. Many methods have been used to removenoise types, ...

Seismic characterization of the Quaternary sediments at Llancanelo-Lake Area, Argentina
(Geophysical Press, 2013-02)
A preliminary near-surface seismic survey was carried out at LlancaneloLake (Argentina) with the aim of mapping the quaternary layers, composed of sedi-mentary layers overlying basalt. A geological model has been obtained ...
