Description

High-resolution (scale in meters) seismic cross section of a subsurface clay-bounded channel containing a dense, nonaqueous phase liquid contaminant. Black lines are the depth-migrated surface seismic reflection data. The reflection data and the red and yellow colors outline the contaminated channel in the center of the image. (Image from F.
