by its location immediately south of the Absecon Inlet jetty. The beach 
is very broad and flat, due to the fillet joining the shoreline from the 
jetty to the normal coast. The profile showed some erosion between the 
2-foot and MSL contours, with substantial accretion occurring above the 
3-foot contour, where the sand level accreted 1 to 2 feet over a distance 
of more than 500 feet. With the exception of profile line 01, maximum 
erosion at the Atlantic City profile lines was observed between the 6- 
and 4-foot contours. Accretion was observed below the 1-foot contour on 
five of the seven profile lines.

Profile lines 01 to 04 are located in an area where 165 cubic yards 
per foot of beach fill was placed in June and July 1970, with approximately 
48 percent of the total fill volume placed above MSL (Everts, DeWall, and 
Czerniak, 1975). Therefore, at the time of the December 1970 storm, the 
beach may not have been in equilibrium and net-volume changes at profile 
lines 01 to 04 could reflect this condition. 
The average net volume change above MSL on the seven Atlantic City 
profile lines was -0.3 cubic yards per foot. This figure is heavily 
weighted by profile line 01, which showed the maximum accretion (24.4 
cubic yards per foot) measured in this study. Excluding profile line 01, 
the average net change was -4.4 cubic yards per foot. 
Pipe profiles were located along profile lines 05 and 07. At profile 
line 05, pipes 1 to 8 were read on both 24 November and 18 December 1970. 
Maximum erosion at any one of the pipes was 1 foot, measured at pipe 8 
where the sand level changed from 4.1 to 3.1 feet MSL. There was no 
accretion at any of the pipes.
