sites 7, 8, and 9. "^^le haustorid amphipod, B. quoddyensis , was most 

 abundant on site 9. The other, less abundant species did not yield 



interpretable results in the a posteriori tests. 



e. Physical Data . Water temperatures were recorded at each site 

 (Table 18). Bottom temperature varied from 10.3° Celsius in March to 

 24.9° Celsius in July. Temperature usually decreased as the distance 

 from shore increased. The greatest temperature range, 2.3° Celsius 

 between sites 1 and 9, occurred in June. 



Salinities were recorded on the bottom at each site (Table 19), 

 and ranged from 30.1 parts per thousand in June to 35.8 parts per 

 thousand in March. Salinity gradually increased with increased 

 distance from shore because of the diluting effect of ground water 

 nearshore. The greatest salinity range was 2.37 parts per thousand 

 between sites 1 and 9 in October. 



The vertical distance from a site to MSL varied between samplings 

 (Table 20) . The method of locating the zero point on the transects 

 caused the site location to depend upon the level of the tide and the 

 sea conditions during sampling. The site elevations were affected by 

 seasonal changes in the slope of the beach face, especially at the deep 

 sites. The greatest elevational change was at site 1 on transect III; 

 the elevation was 0.24 meter below MSL on 20 November 1975 and 1.4 

 meters above MSL on 8 April 1976. 



The mean grain size (in phi), sorting, skewness, and kurtosis of 

 the sediments were determined for each site (Tables 21 to 24) . The 

 bottom material generally was fine but poorly sorted at sites 7, 8, and 

 9, and coarse but well sorted at sites 1, 2, and 3. Site 5 was in a 

 transitional area between the coarse inner beach sediments and the 

 fine deepwater sediments, and grain-size statistics were variable for 

 this site. 



The total organic content of the sediments (in grams per 100 grams) 

 was determined for each site (Table 25) . Organic content was generally 

 low, and ranged from 0.00 to 2.17 grams per 100 grams with both the low 

 and the high values occurring in the October 1975 sampling. Although a 

 clear pattern of organic content distribution did not emerge, organic 

 content was slightly higher at the deep sites than at the swash zone 

 sites. 



The total carbonate content (in grams per 100 grams) of the 

 sediments was determined for each site (Table 26), and was usually high 

 on sites 1, 2, and 3 and low on sites 7, 8, and 9. The highest carbo- 

 nate content was 26.15 grams per 100 grams on site 5, where the con- 

 centration was often high because broken shells accumulated at the 

 interface between the outer planar facies and the inner rough facias. 

 Carbonate content on the inshore sites ranged from 2.19 to 17.78 grams 

 per 100 grams; concentrations on the deep sites (7, 8, and 9) ranged 

 from 0.28 to 2.83 grams per 100 grams. There was no pattern in the 

 distribution of carbonate within the two groups of sites.
