This appendix contains the most recent detailed sediment survey data for 



the FRF, collected by CERC divers in August 1979. A summary of the data is 



provided by Allan E. IteWall, CERC Coastal Processes and Structures Branch. 



Kejmotes on the bed-form descriptions and RSA analysis of the samples are as 

 follows: 



Sample No. - Corresponds to number on sample bag. 



Range - Distance north or south (in meters) from pier. 



Distance - Distance offshore (east, in meters) from FRF base line. 



Depth - Leadline depth (in meters) below SWL (not corrected for 

 tide). 



Date-Time - First number is day in August 1979 (7, 8, or 9); second 



number is eastern daylight time (e.d.t.) or commonly called 

 daylight savings time . 



Description - Visual observation of bottom at time sample was taken. 



Symbols - X = ripple wavelength 



a = ripple height 



K = magnetic azimuth of ripple crest (350" is approximately 

 shore parallel).
