Figure 17. Wind diagram from data recorded at Atlantic City 
for parts of October and November 1962. Storm 
occurring 3 November was a "classic northeaster." 
in above MSL sand volume which occurred during the interval are given in Table 3. 
Profile lines 3 to 14, 16, 17, and 20 were not protected by structures and expe- 
rienced general erosion except at profile lines 5, 6, and 13. The latter three 
showed accretion with profile line 13 gaining 21.83 cubic meters per meter in 
sand volume while adjacent profile lines 12 and 14 suffered erosion. This was 
the greatest gain of any profile measured. Greatest losses occurred at profile 
lines 4, 10, and 16. The reasons for the extreme variability in volume change 
are not clear, but may be related to differential wave refraction and wave 
focusing. 
(3) Winter Storm, 13 January 1964. A severe winter storm which developed 
strong winds from the northeast and north hit the New Jersey coast in January 
1964 causing blizzard conditions, coastal erosion, and maximum high tide 
levels (Table 2). Winds recorded at Atlantic City during this period exceeded 
72 kilometers per hour and were above 54 kilometers per hour for a 3-day period 
surrounding 12, 13, and 14 January (Fig. 18). Surveys of the beach were taken 
on 27 December 1963 and again on 15 January 1964 as the storm was abating. 
Erosion along the island was general except at profile line 21. Losses from 
profile lines 13, 18, and 19 were also anomalously small compared to the other 
profiles. Profile lines 18 and 19 are surrounded by older groins, but, since 
the groins recorded as built in 1964 were probably not yet in place, the rea- 
son for only a moderate loss at profile line 13 is not clear. Profile lines 
1 to 4 at the north end of the island were apparently protected from the north- 
east waves by the Barnegat Inlet jetties (Fig. 2).
