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)...

Fluid expulsion sites on the Cascadia accretionary prism: mapping diagenetic deposits with processed GLORIA imagery Fluid expulsion sites on the Cascadia accretionary prism: mapping diagenetic deposits with processed GLORIA imagery
Point-discharge fluid expulsion on accretionary prisms is commonly indicated by diagenetic deposition of calcium carbonate cements and gas hydrates in near-surface (

Directions of ground-water flow and locations of ground-water divides in the Lost River Watershed near Orleans, Indiana Directions of ground-water flow and locations of ground-water divides in the Lost River Watershed near Orleans, Indiana
The U.S. Geological Survey, in cooperations with the U.S. Army Corps of Engineers, conducted a study during October 1993-April 1994 to improve an understanding of the hydrology of the Lost River watershed near Orleans, Ind. Elements of the study included: (1) constructing a map of the composite ground-water potentiometric-surface of the study area, (2) injecting and recovering...

Hydrologic data for northern Bucks County, Pennsylvania Hydrologic data for northern Bucks County, Pennsylvania
Hydrologic and water-quality data were collected in northern Bucks County, Pa., as part of a study conducted by the U.S. Geological Survey, in cooperation with Bridgeton, Buckingham, Nockamixon, Plumstead, Solebury, Springfield, Tinicum, and Wrightstown Townships and New Hope Borough. Hydrologic data on ground water and surface water were collected to provide basic information on the...

Trace elements in canvasbacks (Aythya valisineria) wintering in Louisiana, USA, 1987-1988 Trace elements in canvasbacks (Aythya valisineria) wintering in Louisiana, USA, 1987-1988
We determined trace element concentrations in livers of canvasbacks (Aythya valisineria) collected at Catahoula Lake and the Mississippi River Delta, Louisiana during, the winter of 1987–1988. Forty percent of canvasbacks wintering at Lake Catahoula had elevated concentrations of lead (>6·7 μg g−1 dry weight) in the liver; 33% had concentrations consistent with lead intoxication (>26·7...

Observations on the occurrence of bacterial gill disease and amoeba gill infestation in rainbow trout cultured in a water recirculation system Observations on the occurrence of bacterial gill disease and amoeba gill infestation in rainbow trout cultured in a water recirculation system
Spontaneous outbreaks of bacterial gill disease (BGD) occurred in 17-44-g rainbow trout Oncorhynchus mykiss after they were placed in a water recirculation system. In each of five groups stocked from September 1991 through July 1992, BGD occurred within 6–8 d after stocking. In each instance, BGD was followed by a secondary amoeba infestation. The spontaneous BGD outbreaks did not occur...
