Perspective view of a combined variance and amplitude extraction on the first post-avulsion reflector, overlain on a variance extraction at the MTC top. The yellow line indicates the location of the cross-section. The amplitudes are erratically distributed with a small cluster of higher amplitudes at the toe of the levee, outboard of an underlying megaclast. A more detailed explanation can be found in Ortiz-Karpf et al (2015). The link to the paper can be found in the docs and links tab.
