USGS 7.5 Minute Quadrangles for Chesapeake Bay and the Delmarva Peninsula Coastal Bays

Showing Distribution, Abundance, and Ground Truthing of SAV in 1997. [Boundaries of Individual

SAV Beds Are Delineated by Solid Lines and SAV Beds Are Shaded. Each Bed Is Identified with an Unique One or Two Letter (A-Z, AA-ZA, AB-ZB, etc.) and One Number (1-4) Designation.

These Numbers Represent the Density Classification Discussed in the Text and Figure 8, i.e., 1 =

<10%; 2 = 10-40%; 3 = 40-70%; 4 = 70-100%. Ground Truthing is Represented by Symbols and

Species Codes which Are Explained in the Legend. Dashed Lines Represent Chesapeake Bay

Program Segment Boundaries. Chesapeake Bay Program Segments Are Identified by Chesapeake

Bay Program Segment Code Designations.]
