Appendix A 

 Survey Data 



Contour diagrams constructed from the bathymetric survey data are presented in this appendix. 

 The profile lines surveyed are identified on each diagram. Contours are in half-meter increments 

 referenced to NGVD. The distance offshore is referenced to the FRF monumentation baseline behind 

 the dune. 



Changes in FRF bathymetry diagrams constructed by contouring the difference between two con- 

 tour diagrams are also presented with contour intervals of 0.25 m. Wide contour lines show areas of 

 erosion. Other areas correspond to areas of accretion. Although these change diagrams are based on 

 considerable interpolation of the original survey data, they do facilitate comparison of the contour 

 diagrams.
