Side-scan sonar imagery overlain on bathymetry reveals a northeast-trending sand-ridge morphology offshore. This trend is opposite that found in areas north of Tampa Bay, particularly transects 1-4. Nearshore surface-sediment cover is thin and exhibits a patchy and discontinuous distribution. Low backscatter (light gray) areas correspond to sand ridges and flats dominated by siliciclastic quartz sand. The dark (high backscatter) areas are largely coarse sediment veneer with increased carbonate material (primarily shell material) or some hardbottoms.
