Observations were made on two midtemperate mid-continental shelf ocean dumpsites affecting at least 1000 sq. nautical miles. The hydrographic regime generally approximated the classic winter isothermal-summer stratified system but incursions of fresher water from the Del. estuary and intrusion of offshore slope water influenced this hydrographic regime. The distribution of metals in bottom sediments and organisms indicate these potentially toxic materials persist in bottom materials and are apparently translocated as a result of hydrographic forces, increasing their potential toxicity to a relatively great area. There is evidence of accumulation in benthic organisms, notably the mahogany clam, Arctica islandica, and the scallop, Placopecten magellanicus, with some mortalities.
