1976. However, there were wide variations in these parameters in 

 the northernmost 30 kilometers of North Carolina beach, with no 

 apparent relation between beach-face slope and grain size. 



The large variations in grain size were observed to be due to 

 longshore fluctuations in the coarse red sand. These fluctuations, 

 which ranged between 4 and 20 kilometers north of Duck, were quite 

 visible during the monthly aerial flights. 



The high- and low-angle beach faces measured in Currituck County 

 were observed to be indications of convex-accretional and concave- 

 erosional profile lines, respectively. The steepest beaches were 

 measured in May, August, September, and November; the lowest angle 

 beaches were measured in April, February, July, and January, respec- 

 tively. 



These data provide background information useful for planning of 

 experiments at the new CERC Field Research Facility, just as the 

 Virginia data provide information useful for study and analysis of that 

 shore area.
