Bathymetry 



Two rod and level beach profile surveys were conducted, one in September 1995, and 

 the second in September 1996. During each survey, the same 33 profiles were measured 

 north and south of the inlet. Profile lines were run from the State of Florida, Department 

 of Environmental Quality, beach profile bench mark numbers R-121 to R-176, Volusia 

 County. Profiles near the inlet (R-139 to R-148 and R-150 to R-160) were run at every 

 bench mark. Further north (R-121 to R-136) and south (R-164 to R-176) of the inlet, 

 every third bench mark was used. All profile lines ran north 60 deg east from the bench 

 marks. Most profiles started at the bench mark and extended out to approximately 2 m 

 depth. 



Bathymetry throughout the inlet, back bays, beaches, and ocean was obtained during 

 four SHOALS surveys, in July 1994, September 1995, September-October 1996, and 

 December 1997. The SHOALS system consists of a helicopter-mounted laser that rapidly 

 obtains above- and below-water vertical elevations using differential Global Positioning 

 System (GPS) for horizontal control. The SHOALS Airborne Lidar Hydrographic Survey 

 System is described in more detail in Irish, Lillycrop, and Parsons (1996) and Lillycrop, 

 Parsons, and Irish (1996). See also the World Wide Web site (http://bigfoot.wes.army. 

 mil/6022.html). The July 1994, Ponce de Leon SHOALS survey data are discussed in 

 Irish, Parsons, and Lillycrop (1995) and Stauble (1998). 



Sediment Collection 



A set of 105 sediment samples was collected at Ponce de Leon Inlet from 

 18-22 September 1995. (A second set of 106 samples collected from 

 15-18 September 1997, at similar locations, has not been analyzed). Differential 

 GPS was used to locate surface grab samples, which were collected by boat with a
