APPENDIX D 

 RESULTS OF THE JULY 1975 SAMPLING ON THE SOUND BEACH 



The sieving technique used to extract the July 1975 samples was 

 less sensitive to small and medium-size organisms than the rinsing 

 flotation technique used on subsequent samples. Thus, the July 1975 

 samples were not compared to subsequent samples. 



The average number of Monooulodes sp., S. v-iridis L. dysticus , 

 Petosoolex sp., chironomid larvae, Gammarus sp., Cyathura polita, 

 and total organisms per square meter was determined (Table D-1) . 

 Physical data, mean grain size and sorting, and total organic and 

 carbonate content of the sediments were measured (Tables D-2, D-3, 

 and D-4) . 



The results of the July sampling supported the general conclusions 

 in the text. Two communities were present, the marsh community on 

 transect IV and the L. dystiaus community on transects IV and V. 

 Sites 7 and 8 were not measured, but included the S. viridis community. 

 Sootecotepidis viridis increased in number with increased distance from 

 shore, but had low densities on transect VI. The marsh community was 

 poorly developed in July 1975, and few characteristics species were 

 present .
