Table 12-1 lists invertebrate macrofaunal species col- 

 lected in New York Bight by trawls or dredges during 

 July-November 1976. Detailed listings of impacts are 

 available (Steimie 1977). 



GRAB COLLECTIONS 



Data from 1 1 stations sampled in April 1975 (table 12-2) 

 and resampled during October and November 1976 (Pearce 



et al. 1977) are compared. To simplify analysis and inter- 

 pretation of impacts, the tables include only species taken 

 at three or more stations. Table 12-3 shows the results 

 from the remaining 19 processed stations. 



DISCUSSION 



The benthic invertebrate fauna of New York Bight is 

 dominated by organisms adapted to relatively clean po- 

 rous sands (Pratt 1973; Pearce et al., in press). This fauna 

 does not normally experience extended periods of anoxia
