APPENDIX A 



SELECTED GEOPHYSICAL PROFILES 



Appendix A contains line profile drawings of selected seismic 

 reflection records from the Fort Pierce grid area. 



Fix numbers and point of crossing lines are plotted along the 

 upper margin of the profile. 



The bottom and all subbottom reflectors are delineated and 

 those reflectors mentioned in the text are identified by letter 

 symbols. 



All depths are in feet below mean sea level; and based on an 

 assumed sound velocity of 4,800 feet per second in water and 5,440 

 feet per second in the subbottom. 



Position of lines and fixes are plotted on Figure 2.
