A crisis in waste management, economic vitality, and a coastal marine environment: Boston Harbor and Massachusetts Bay A crisis in waste management, economic vitality, and a coastal marine environment: Boston Harbor and Massachusetts Bay
Discharge of sewage sludge and effluent from 43 communities in the greater Boston metropolitan area has helped make the harbor one of the most polluted in the nation. As part of a court-mandated plan to end pollution of the harbor, effluent will no longer be discharged into the harbor, but instead, by 1995 it will be discharged into Massachusetts Bay through a record-long 15.34 km tunnel...

Seismic character of gas hydrates on the Southeastern U.S. continental margin Seismic character of gas hydrates on the Southeastern U.S. continental margin
Gas hydrates are stable at relatively low temperature and high pressure conditions; thus large amounts of hydrates can exist in sediments within the upper several hundred meters below the sea floor. The existence of gas hydrates has been recognized and mapped mostly on the basis of high amplitude Bottom Simulating Reflections (BSRs) which indicate only that an acoustic contrast exists at...

A sediment budget for southern Lake Michigan: source and sink models for different time intervals A sediment budget for southern Lake Michigan: source and sink models for different time intervals
We have constructed a sediment budget for the southern Lake Michigan basin for sand and for mud during three time periods: the past 100, 5,000, and 10,000 years. For the modern (100-year) sediment budget, accountable sediment sources add up to 93 percent of the calculated sinks. The mud budget has a source deficit of about 40%, probably due to errors in mud:sand ratios and (or) to other...

Relationship between resistance of salmonids to furunculosis and recovery of Aeromonas salmonicida from external mucus Relationship between resistance of salmonids to furunculosis and recovery of Aeromonas salmonicida from external mucus
Fish were sampled at the Ed Weed State Fish Hatchery (South Hero, Vermont, USA) in September 1992. Aeromonas salmonicida was common, with concentrations as high as 105 to 107 colony-forming units per gram of mucus, and readily recovered from most mucus samples obtained from furunculosis-sensitive populations of brook trout (Salvelinus fontinalis), lake trout (Salvelinus namaycush), and...

Metal concentration in the gill, gastrointestinal tract, and carcass of white suckers (Catostomus commersoni) in relation to lake acidity Metal concentration in the gill, gastrointestinal tract, and carcass of white suckers (Catostomus commersoni) in relation to lake acidity
Adult white suckers were collected from four lakes in Maine that ranged in pH from 7.0 to 5.4. The gastrointestinal tract and remainder of the carcass of fishes of similar age and size from each lake, and gills from additional fishes of similar size, were analyzed for Al, Cd, Pb, and Zn. Carcasses were also analyzed for Hg. Concentrations of Al, Cd, and Pb were highest in the...

Dioxins and furans linked to reproductive impairment in wood ducks Dioxins and furans linked to reproductive impairment in wood ducks
A wetland in central Arkansas was contaminated with polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans and because the area was a major waterfowl habitat, we studied the effects of the contamination on nesting wood ducks (Aix sponsa) during 1988-90. Residues in wood duck eggs, based on toxicity equivalency factors (TEFs) for combined compounds, ranged from 0.2 to 611...

A comparison of black drum, red drum, and their hybrid saltwater pond culture A comparison of black drum, red drum, and their hybrid saltwater pond culture
Hybridization has been used in aquaculture to produce fish that exhibit improved growth and survival over parent species. Previous studies produced an intergeneric hybrid by crossing female black drum Pogonias cromis with male red drum Sciaenops ocellatus. In the present study, the two parent species and their hybrid were simultaneously cultured in ponds for 9 mo. Two- to three-day-old...
