indicate that size, averaged by beach, decreases from 0.33 millimeter at 

 Long Beach Island in the north, through 0.27 millimeter at Atlantic City, 

 to 0.23 millimeter at Ludlam Island in the south. Size, averaged by profile 

 line, varies from 0.34 millimeter at a profile on the northern half of Long 

 Beach Island, to 0.20 millimeter at a profile in the middle of Ludlam Island. 

 Size also varies with position across the profile from low tide terrace to 

 landward edge of berm, tending to decrease landward across the average of 

 three profiles on Atlantic City and three profiles on Ludlam Island, but 

 tending to increase landward across the average of four profile lines on 

 Long Beach Island. Maximum variation at one beach, averaged by position on 

 profile, occurs at Long Beach Island where the average size increased from 

 0.28 millimeter on the low tide terrace to 0.36 millimeter on the berm. Size 

 Variation by month suggests a tendency for sand to be finer during late summer 

 and early fall, but data do not permit identification of a consistent annual 

 cycle. Maximum variation at one beach over the entire sampling period 

 occurred at Ludlam Island, where size increased from 0.19 millimeter in 

 October 1968 to 0.27 millimeter in March 1969. When classified by month or 

 by position on profile, size at Atlantic City tends to increase when size 

 increases at Ludlam Island, 19 miles to the south, and to decrease when size 

 increases at Long Beach Island, 23 miles to the north. The results in this 

 report provide site-specific engineering data for New Jersey beaches, and 

 suggest ways to improve beach fills at these sites.
