Figure 12. Chirp seismic-reflection profile C–C' with seismic stratigraphic and morphosequence interpretation (arrow pointing from ice-contact to ice-distal deposits). See figure 9 for descriptions of stratigraphic units and major unconformities. The red lines indicate reflections that bound seismic stratigraphic units (fig 9). See figure 16 for profile location. A constant sound velocity of 1,500 meters per second was used to convert two-way travel time to depth, in meters.
