Figure 7. (Top) sidescan-sonar imagery from the western part of the study area, (middle) in the area of seismic-reflection profile B-B' (from Needell and others, 1983b) extending southeast to northwest, (bottom) with interpretation.

Figure 7. (Top) sidescan-sonar imagery from the western part of the study area, (middle) in the area of seismic-reflection profile B-B' (from Needell and others, 1983b) extending southeast to northwest, (bottom) with interpretation. Fluvial, estuarine, and transitional sediments overlie till in the channel and along the southern flank of the northwestern bathymetric high. The bathymetric high also shows small plateaus, which are visible as patches of high and low backscatter in the sidescan-sonar imagery and are interpreted to be erosional outliers. Location of seismic-reflection profile is shown in figure 6.
