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...

Indicators of sewage contamination in sediments beneath a deep-ocean dump site off New York Indicators of sewage contamination in sediments beneath a deep-ocean dump site off New York
The world's largest discharge of municipal sewage sludge to surface waters of the deep sea has caused measurable changes in the concentration of sludge indicators in sea-floor sediments, in a spatial pattern which agrees with the predictions of a recent sludge deposition model. Silver, linear alkylbenzenes, coprostanol, and spores of the bacterium Clostridium perfringens, in bottom...

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...

Identification of marine hydrates in situ and their distribution off the Atlantic coast of the United States Identification of marine hydrates in situ and their distribution off the Atlantic coast of the United States
Natural gas hydrates, mostly methane hydrates, occur within seafloor sediments almost everywhere in the world’s oceans where water depths exceed 300 to 500 m, and hydrates in this setting probably contain very large quantities of methane.’ Gas hydrates have been identified in marine sediments by coring and by the response that they create in seismic reflection profiles. Our research has...

Physiological and hormonal differences among Atlantic salmon parr and smolts reared in the wild, and hatchery smolts Physiological and hormonal differences among Atlantic salmon parr and smolts reared in the wild, and hatchery smolts
Atlantic salmon which had been released as fry in tributaries of the Connecticut River (Northeastern USA) were captured during the migratory period (9 May to 6 June) 1 to 2 years later. Migrants (smolts) were captured above a dam on the main-stem; non-migrants (parr) were captured in two tributaries. Migrants were significantly larger than non-migrants (16.9 and 13.0 cm, respectively)...

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...

Loma sp. salmonids from the Eastern United States: Associated lesions rainbow trout Loma sp. salmonids from the Eastern United States: Associated lesions rainbow trout
A microsporidian of the genus Loma was noted in the gills of rainbow trout Oncorhynchus mykiss from a state hatchery (Buford Trout Hatchery) in Georgia. Mortalities of varying severity occur at this hatchery every fall, and the microsporidian was noted during an experiment from August 1991 to January 1992 to determine the effects of water source on disease. Infections first appeared to...

Evaluation of the effects of an oxygen injection system on the growth, hematology, and immunity of lake trout Evaluation of the effects of an oxygen injection system on the growth, hematology, and immunity of lake trout
Fingerling lake trout (Salvelinus namaycush) were reared for 64 d at three pressures of dissolved gases, expressed in relation to saturation values (▵P)–untreated (control) water, ▵P = 10 mm Hg; water treated by column degassing with air, ▵P = 9 mm Hg; and water treated with an oxygen injection system, ▵P = −20 mm Hg. Dissolved oxygen concentration for experimental groups was increased...
