During the period between 1970 and 1974 additional power- 

 plant monitoring and baseline benthic data from the central Sound are 

 available from studies conducted on the north shore at Bridgeport, and 

 at Northport and Shoreham on the south shore. Subtidal and intertidal 

 infauna and epifauna surveys in Bridgeport Harbor were conducted during 

 1971 and 1972 (NAI, 1973b) as part of an operational baseline program. 

 Ernst (1970) and D'Agostino and Colgate (1973) provided data on the 

 nearshore subtidal communities and potential impacts from plant oper- 

 ation at Northport. Winter polychaete populations in areas in and out 

 of the Northport thermal plume were investigated by Mulstray (1971) . 

 Hechtel (1970) conducted intertidal studies during plant operation at 

 Northport. D'Agostino and Serafy (1974) provided baseline data on s\ib- 

 tidal infauna and epifauna at Shoreham during 1973 and 1974. 



In the western region of the Sound, baseline studies conducted 

 at Stamford, Connecticut, for a proposed nuclear power plant provide 

 infauna and epifauna data collected by techniques comparable to those 

 used in New Haven (NAI, 1974c). Additional intertidal and shallow 

 subtidal studies have been conducted in the vicinity of Stamford (Vil- 

 lage Creek) to assess the impact of a minor fuel oil spill (NAI, 1974f) . 



In the eastern Sound inshore subtidal and intertidal studies 

 were conducted at Niantic Bay for Northeast Utilities by Battelle (1977) 

 and in the upper reaches of Niantic Bay for the City of New Haven (NAI, 

 1975b) . Subtidal infaunal and epifaunal studies were also conducted at 

 New London (Thames River) for a major dredging program (Department of 

 the Navy, 1977, unpublished). 



Exposure panel surveys were less common than other benthic 

 programs. Clapp (1937) conducted an early study of fouling along the 

 New England coast and included stations in New Haven. Subsequent to 

 Clapp 's work, exposure-panel data have been collected at New Haven and 

 Niantic Bay from 1971 through the present (NAI, 1971, 1973a, 1974a, 

 1974b, 1975a, 1976a, 1977a, 1978; Battelle, 1977). Sampling frequency 

 and techniques at the two sites are comparable. Compatible data have
