December 1963 to January 1964, showing a northeast 
storm of 12 January and beach surveys. The gap from 
30 December through 2 January is from a change in

(4) Northeast Storm, 12 November 1968. A short-lived, intense north- 
east storm with rain, snow, and wind caused erosion along the island during 
the survey interval from 23 October to 13 November 1968 (Fig. 19, Table 2). 
Erosion was widespread and severe, particularly north of the causeway and in 
segments to the south. Profile lines 1 and 2, enclosed by the jetties, showed 
erosion and accretion, respectively. Profile lines 3 and 4 suffered a severe 
loss of sand volume. This is in contrast to the response shown for the 13 
January 1964 storm during which the profile lines were protected by the jetty. 
Since both generated high storm tides, differences in the wind patterns may 
account for the response. Winds during the January storm were from the west 
northwest, with the Atlantic beach face protected, on the 1lth and began to 
develop strongly from the north-northeast, essentially parallel to shore, on 
the 12th. The winds remained strong but rotated counterclockwise blowing from 
the west on the l6th. This is the classic pattern of winds generated by a low- 
pressure system seaward of the island moving up the coast. A similar, though 
much less intense low on 10 November 1968 followed the same pattern as the 
13 January 1964 storm. This storm, however, was followed by intense winds 
from the east-northeast in a direction nearly parallel to the south Barnegat 
Inlet jetty. This direction of wave approach combined with local refraction 
which may have focused the wave energy was apparently sufficient to cause a 
large amount of erosion to profile lines 3 and 4 as well as others. Profile 
lines 6 to 12 were also severely cut back during this event, as were profile 
lines 14 and 15. The south end of the island from profile line 15 showed 
great variability with profiles alternately eroding and accreting (Table 3). 
Most of the groins were in place during this period with the exception of the
