Results and Interpretations

The sidescan-sonar image shown in Figure 1 illustrates the variety of acoustic facies present within the study area. The distinction between similar acoustic facies (e.g., within and between high backscatter areas) is only possible by field groundtruth. Thus, the image interpretation shown in Figure 4 and described here is supplemented by the analysis of surficial sediment and vibracore data collected at the sites shown in Figure 3 (see figure to the right), along with extensive diver observations. The locations of other figures described in the following pages are shown in Figure 5.
