APPENDIX B 



GRANULOMETRIC DATA 



Appendix B contains the results of Rapid Sand Analyzer (RSA) size 

 analyses of selected sediment samples from CERC cores in the study area. 

 Analyses are based on sand-size fraction only. 



The samples are identified by core number, CERC identification, and 

 sample interval below top of the core. These samples are plotted by 

 core number in Figure 2. 



Data include mean (X) size values (phi and millimeter) and standard 

 deviation or sorting coefficient (a) from direct RSA analyses. 



CERC has determined empirical relations for converting RSA means and 

 standard deviation to sieve analyses equivalents. The relationships, 

 developed from RSA and sieve analyses at a 0.25-phi interval, are: 



means: X , . , = 1.0735 X.^c,. + 0.1876 



Sieve millimeter values were derived by means of a conversion table. 



RSA standard deviation values were converted to sieve sorting 

 equivalents by the formula: 



standard deviation: aj,sieve = 1.4535 a^RSA - 0.146 



Cumulative curves of selected samples from CERC cores are presented 

 graphically. Sample locations are shown in Figure 2. Data are derived 

 from RSA analyses.
