Figure F20. Seismic section from MCS Line 89-08 with overlay of lithostratigraphic units. The base of Unit I may be correlated to a shallow reflector that can be traced across the entire section shown. The boundary between Units II and III is an unconformity, which can be traced clearly between common depth points (CDPs) 3575 and 3650. Vertical exaggeration = 2.0.
