subbottom profiles

Figure 2: 3.5-kHz subbottom profiles across one of the low-relief ridges off Sarasota, FL. Profile locations are shown in figure 1. Top profile is shoreward of this ridge. The second profile crosses the ridge where it has about 1 m relief. The third profile crosses where the ridge has about 3 m relief. Note the horizonatal reflector underlying the ridge and the transparent nature of the ridge deposits. The fourth profile is the farthest offshore, and crosses where the ridge is decreasing in relief again.
