study. Faunal density was extremely variable with an annual minimum in 

 sioitimer and a maximum in winter. The summer minimum or "August effect" 

 in New Haven Harbor appears to have been associated with the combined 

 stresses of low dissolved oxygen, organic rich silt-clay substrata, 

 and an inner harbor location. 



Analysis of species richness, faunal density and diversity for 

 significant changes between preoperational and operational periods 

 revealed no apparent impact of the New Haven Harbor Station on the 

 benthic infaunal assemblages of New Haven Harbor.
