1994, February 1995, March 1995, November 1995, November 1997, Janu- 

 ary 1998, and February 1998. The January and February 1998 storms were the 

 most severe and resulted in widespread beach erosion and coastal flooding along 

 the New Jersey and Delaware coastlines. 



Positions of CORE-LOC Armor Unit Targets 



Initial data were obtained for the CORE-LOC armor units recently installed 

 on the heads of the north and south jetties through photogrammetric analysis. 

 Dependent upon the position of the CORE-LOCs, one to three targets were esta- 

 blished on each unit. A view of a CORE-LOC armor unit with three targets is 

 shown in Figure 31. The northing and easting horizontal positions and the eleva- 

 tions of the CORE-LOC targets are presented in Table 8. These data establish a 

 base from which to evaluate armor unit movement during future surveys.
