2.4 Sample Processing 



Sediment grain size analysis was performed using a combination of wet-sieving and 

 flotation methods (Folk, 1968; Galehouse, 1971). Sediment organic content was measured 

 by loss upon ignition (550° C). No organic content analysis was performed on the 1990 

 samples and none was possible in 1998 due to imavoidable delays in sample shipment. In 

 the laboratory infaunal samples were rinsed over a 0.5 mm mesh sieve to remove formalin, 

 transferred to 70% ethanol and stained with rose bengal solution to facilitate sorting of 

 specimens. After staining, the samples were rinsed to remove excess stain, examined under 

 3X magnification, specimens separated from the remaining sediment and detrims and 

 stored in 70% ethanol. Specimens were then identified to the lowest practical taxonomic 

 level and enumerated. Wet-weight biomass was determined for major taxonomic groups 

 (e.g., Polychaeta, Crustacea).
