(b) Visual observations by U.S. Coast Guard personnel from the 

 Frying Pan Shoals Light Tower. The wave data with the monthly 

 wave statistics were provided by CERC. 



(c) Long-term deepwater wave statistics provided in the Summary of 

 Synoptic Meteorological Observations (SSMO) (U.S. Naval Weather 

 Service Command, 1975). 



(d) CERC's wave observation program at Wrightsville Beach provided 

 visual observations of wave conditions, recorded daily at 

 Johnnie Mercer's Pier between June 1970 and December 1973. 

 CERC provided the monthly statistical analysis of these 

 shore-based wave observations including breaking wave height, 

 period, and direction. The wave data collected at Wrightsville 

 Beach during the study period are available in supplementary 

 data Volumes II, III, and IV. 



3. Beach Sand Data . 



Beach sand data for certain profiles within the study area from 1969 

 to 1971 were provided by CERC. Samples were collected along the profile 

 azimuth from the dune crest, the berm, and at MHW, MSL, MLW, -1.8 meters 

 (-6 feet) (MLW), -3.66 meters (-12 feet) (MLW) , and -5.49 meters 

 (-18 feet) (MLW). Frequency of sand sample collection was not con- 

 sistent from beach to beach or from profile to profile. The sand was 

 analyzed for basic engineering properties including grain-size distribu- 

 tion, median grain size, standard deviation, fall velocity, and compo- 

 sition. Grain-size analyses are summarized in Table 3. The complete 

 sand data are presented in supplementary data volumes for each beach 

 segment (except for Kure Beach).
