Analysis 



57. The sediment samples were sieve-analyzed to determine the size dis- 

 tribution of the samples. The sieves were at 1/2-phi intervals (phi = log 

 sediment diameter (mm)). This report presents a sununary of the texture 

 analysis . 



Photographic Data 



Aerial 



58. Quarterly aerial photographic missions were performed by a con- 

 tractor using a 9-in. -negative-format mapping aerial camera capable of black- 

 and-white and color photography. All coverage was at least 60 percent over- 

 lap, with all flights flown as close as possible to periods of low tide 

 between 1000 and 1400 hours, with less than 10 percent cloud cover. 



59. The flight lines were concentrated near the FRF, although one 

 flight line extended from Cape Henry, Va., to Cape Hatteras, N. C. The 

 flight lines and scale specifications are shown in Figure 4. 



Beach 



60. As part of the visual observations, 35mm color slides of the beach 

 were taken daily from the pier looking toward both north and south. The loca- 

 tion from which each picture was taken, date, time, and a brief description of 

 the picture were marked on the slides, and an inventory was maintained. 

 Analysis 



61. There was no routine analysis of the photographic data except to 

 inventory what was obtained.
