Separation of PS-wave Reflections from Ultrashallow Water OBC Data Using Elastic Wavefield Decomposition

Elastic wave decomposition, aiming at separating the converted modes from the P waves, is applied to high-resolution OBC data acquired in the River Danube, Hungary. The decomposition relies on accurate knowledge of the water-bottom elastic parameters and on a perfect sensor calibration and coupling. The available decomposition schemes require an...

Methodology for dense spatial sampling of multicomponent recording of converted waves in shallow marine environments

A widespread use of converted waves for shallow marine applications is hampered by spatial aliasing and field efficiency. Their short wavelengths require dense spatial sampling which often needs to be achieved by receivers deployed on the seabed. We adopted a new methodology where the dense spatial sampling is achieved in the common-receiver...
