Age dating of shallow groundwater with chlorofluorocarbons, tritium/helium: 3, and flow path analysis, southern New Jersey coastal plain Age dating of shallow groundwater with chlorofluorocarbons, tritium/helium: 3, and flow path analysis, southern New Jersey coastal plain
Groundwater age dating through the combination of transient tracer methods (chlorofluorocarbons (CFCs) and tritium/helium 3 (3H/3He)) and groundwater flow path analysis is useful for investigating groundwater travel times, flow patterns, and recharge rates, as demonstrated by this study of the homogeneous shallow, unconfined Kirkwood-Cohansey aquifer system in the southern New Jersey...

Effects of growth hormone and insulin-like growth factor I on salinity tolerance and gill Na+, K+ and -ATPase in Atlantic salmon (Salmo salar): Interaction with cortisol Effects of growth hormone and insulin-like growth factor I on salinity tolerance and gill Na+, K+ and -ATPase in Atlantic salmon (Salmo salar): Interaction with cortisol
The potential roles of growth hormone (GH) and insulin-like growth factor I (IGF-I) in seawater (SW) acclimation of juvenile Atlantic salmon (Salmo salar) were examined. Compared to controls, fish in 12 ppt seawater given one or three injections (2–6 days) of GH (ovine, 0.2μg · g−1) or IGF-I (recombinant bovine, 0.05–0.2μg · g−1) had significantly greater salinity tolerance as judged by...

Feeding trials with juvenile Atlantic sturgeons propagated from wild broodstock Feeding trials with juvenile Atlantic sturgeons propagated from wild broodstock
Juvenile Atlantic sturgeons Acipenser oxyrinchus produced by hormone‐induced spawning of wild broodstock from the Hudson River, New York, were used in a diet study. Fish fed live Artemia sp. as first‐feeding fry for 35 d were observed to convert readily to formulated diets. At 79 d posthatch, four formulated feeds were offered: sturgeon starter 9304, Biokyowa, Zeigler esocid diet, and...

Gas-phase axial dispersion in a spray tower Gas-phase axial dispersion in a spray tower
Gas-phase axial dispersion (mixing of the composition of the gas phase along the longitudinal axis) was characterized in an enclosed spray tower for purposes of establishing reactor type for the solute-solvent pair oxygen and water. Test condition variables were spray tower height (TH), 1·52, 2·03 and 2·54 m; hydraulic loading (HL), 44·2, 66·3 and 88·4 kg/m2s; the ratio of volumetric...

Epizootiological study of bacterial cold-water disease in Pacific salmon and further characterization of the etiologic agent, Flexibacterin psychrophila Epizootiological study of bacterial cold-water disease in Pacific salmon and further characterization of the etiologic agent, Flexibacterin psychrophila
Isolates of Flexibacter psychrophila were obtained from chinook salmon Oncorhynchus tshawytscha and coho salmon O. kisutch that had previously sustained epizootics of coldwater disease. The pathogen was readily isolated from kidney and mucus of convalescent fish. The organisms were relatively inert in most standard microbiological media but were structurally and serologically homogenous...

Character, paleoenvironment, rate of accumulation, and evidence for seismic triggering of Holocene turbidites, Canada Abyssal Plain, Arctic Ocean Character, paleoenvironment, rate of accumulation, and evidence for seismic triggering of Holocene turbidites, Canada Abyssal Plain, Arctic Ocean
Four box cores and one piston core show that Holocene sedimentation on the southern Canada Abyssal Plain for the last 8010 ± 120 yr has consisted of a continuing rain of pelagic organic and ice-rafted clastic sediment with a net accumulation rate during the late Holocene of ⩽10 mm/1000 yr, and episodically emplaced turbidites 1–5 m thick deposited at intervals of 830 to 3450 yr (average...
