bucket dredge on the ebb and flood shoals and in the inlet throat. Surface grab 

 samples were collected with a hand-held scoop on both the updrift and downdrift 

 beaches and on some of the exposed flood deltas. These samples represent the 

 present-day surface sediment distribution. Several patterns of sampling were 

 applied, depending on the area of the inlet. 



On the ebb shoal a radial pattern was sampled extending from the throat 

 seaward over the back face, crest, and front face of the shoal on five radial lines for 

 a total of 28 samples. Figure 70 and Table 7 (see Chapter 3, p. 58 "Sediment 

 Results" Section) use the same notation presented in the following station 

 descriptions. Line N (north transect) and Line NE (northeast transect) both had 

 three samples. Line CL (the center line of the inlet channel) and Line SE 

 (southeast transect) both had seven samples. Line S (south transect) had five 

 samples. Three samples were also collected on a line parallel to the north jetty 

 (NJ 1 to 3) to characterize the near shore shelf sediment north of the jetty and ebb 

 shoal. Three samples were taken on each of four transect lines across the inlet 

 throat for a total of 12 samples. These channel samples were designated CH Al 

 through D3. Samples were collected in two environments at the flood shoal. Four 

 samples were collected in each of three deeper flood tidal channels, which are for 

 navigation into the Halifax River Lagoon to the north (NFC), Rockhouse Creek in 

 the center (CFC), and in the Indian River North Lagoon, to the south (SFC). Five 

 samples were collected on the two roughly triangular shaped flood tidal shoals, 

 which were exposed at low tide and were designated as the north flood shoal 

 (NFS) and south flood shoal (SFS). Twelve samples were collected in the flood 

 channels and ten on the flood shoals. Inlet-adjacent beaches were also sampled 

 along Florida Department of Environmental Protection profile lines, at the high- 

 tide (HT), mid-tide (MT), low-tide (LT), and nearshore (OS) located approxi- 

 mately 61 to 76 m (200 to 250 ft) seaward of the mid-tide sample at time of low 

 tide. Four profiles were located up to 1,829 m (6,000 ft) north of the inlet (R142 

 to R148) and six lines (R150 to R160) were located up to 3,048 m (10,000 ft) to 

 the south. 



Four additional beach samples were collected at the mid-tide location at sites 

 south of the inlet: at R176 in New Smyrna Beach 6.9 km (11 miles) south of the 

 inlet, at two sites at Bethune Beach 14.5 and 16.1 km (23.2 and 25.8 miles) south 

 of the inlet, and at Canaveral National Seashore 30.6 km (49 miles) south of the 

 inlet. 



Visual Imaging 



Six video cameras were set up on top of the Inlets Condominium just south of the inlet 

 in positions that had clear views of the north and south coasts, the inlet, and the flood and 

 ebb shoals. The cameras operated for most of the days between 28 February and 

 13 August 1996, when a presumed lighting strike destroyed some of the electrical 

 components. During daylight hours the cameras were operated sequentially with each
