storm since individual lines experienced large losses. Median volume change 

 for the 46 cases was -10 m-^/m. 



63. The largest median volume change (-31.4 m^/m on 18 March 1973) 

 occurred at Westhampton Beach. Individual profile changes, represented by 

 the extreme values, were quite large, up to -150 m^/m for profile line 1 at 

 Atlantic City. Probably as a result of its sheltered location, Misquamicut 

 eroded the least and had the least variation between profile lines. 

 Misquamicut and Ludlam Beach had the smallest ranges in variation between 

 profile lines whereas Nauset Beach and Jones Beach had relatively large 

 ranges. Because the number of beaches surveyed for each storm varied 

 considerably, it is difficult to compare storms. However, Figure 16 

 illustrates the large amount of variation which naturally occurs between 

 beaches subjected to the same storm.
