Abstract:

The report considers the activities and findings of the several integrated research projects designed to monitor the environmental effects of dredging in the Thames River and dredge spoil disposal at the New London Dumping Ground. The report addresses field activities conducted and results obtained. UCONN completed three additional cruises in the Thames River to investigate suspended material transport. Progress has been made toward selecting a circulation model for determining dredging-induced variations, and twoard characterizing average loads of suspended sediments during autumn. The UCONN report contains photographic documentation of the nature of spoils at the dump site and evidence of past dumping. SCUBA surveys conducted in late November and early December found no outstanding changes in bottom conditions. The NYOSL reports establish predisposal values for the physical and chemical oceanography of the dump site, and describe changes found in September and December as well as effects of single dumping events at those times. The report also presents predisposal concentrations of heavy metals in benthic animals.
