Session Description:
The analysis of seismic data recorded at onshore and offshore sedimented locations is often complicated by 1) large impedance contrasts between sediments and surrounding crustal rock, 2) localized amplification in unconsolidated sediment layers, and 3) multiple scattering. High-amplitude body wave reverberations in the sediment layer can obscure fainter crustal phases in receiver functions and hinder traveltime picking for tomographic studies. Localized basin amplification and refraction effects can increase uncertainties of array-based source parameter estimates, attenuation studies, surface wave dispersion measurements and tomographic inversions when not properly accounted for. With this session we hope to define and advance the state of the art in regards to characterizing and mitigating the effects of sediments on seismic observations. We therefore encourage contributions highlighting improvements in waveform modeling and inversion, receiver functions, tomography and surface wave analysis in highly reverberatory media.
