side-scan sonar of mud and gravel greater than rock

Figure 5. Side-scan sonar image (right) of M and Rg seafloor types and their interpretation (left). Muddy seafloor is uniformly light gray although the tonal difference on the left edge is a recorder artifact. A mixture of rocky outcrops has an irregular dark gray appearance while gravelly troughs appear smooth and dark gray.
