Three large-format mapsheets (1:30,000) illustrate the bathymetry, sidescan-sonar backscatter data, and surficial geology of the Apalachicola Bay and St. George Sound survey areas. These mapsheets are distributed as Adobe portable document format (PDF) files that can be printed on a large format plotter at 45 x 32 inches.

	Mapsheet 1. Bathymetry, presents a regional bathymetric model for the area using a 25-m grid cell resolution. (PDF format)
	Mapsheet 2. Sidescan-sonar backscatter, shows distribution of backscatter values over the survey area. (PDF format)
	Mapsheet 3. Surficial geology, shows the interpreted surficial geology with the locations of oyster bars superimposed on the sun-illuminated bathymetry. (PDF format)
