W. Seyfried, J. L. Bischoff
1977, Earth and Planetary Science Letters (34) 71-77
Seawater reacted with basaltic glass at 260°C and 500 bars under water-dominated conditions (50 : 1 water/rock ratio) efficiently leached and maintained heavy metals in solution. Cu, Zn, and Ba are transferred in significant proportions to the aqueous phase, while Fe...

M. R. Miller, R.M. McLandress, B.J. Gray
1977, The Auk (94) 140-142
Sexual behavior of the North American Ruddy Duck (Oxyura jamaicensis), as summarized by Johnsgard (1965: 323-327), includes a display variously referred to as the ringing rush (Johnsgard 1965: 325; 1967), ring rush (Johnsgard 1966), and/or display flight (Johnsgard 1966, 1967), which males perform as a short rush across the water...
Recent metalliferous sediment in the North Pacific manganese nodule area
J. L. Bischoff, R.J. Rosenbauer
1977, Earth and Planetary Science Letters (33) 379-388
Quaternary sediments cored in the northeast Pacific nodule area (DOMES site C, 14°N, 126°W) contain a significant amount of hydrothermal metalliferous mud. Water content, color, mineralogy, and chemical composition are analogous to metalliferous sediments of the subequatorial East Pacific Rise.Correction for contribution of pelagic clay indicates the metalliferous fraction to...

Kirkwood M. Cunningham, Marvin C. Goldberg, Eugene R. Weiner
1977, Analytical Chemistry (49) 70-75
The influence of experimental parameters on detection sensitivity was determined for laser Raman analysis of dissolved solutes in water. Individual solutions of nitrate, sulfate, carbonate, bicarbonate, monohydrogen phosphate, dihydrogen phosphate, acetate ion, and acetic acid were measured. An equation is derived which expresses the signal-to-noise ratio in terms of solute...
Reactions of metal ions at surfaces of hydrous iron oxide
J.D. Hem
1977, Geochimica et Cosmochimica Acta (41) 527-538
Cu, Ag and Cr concentrations in natural water may be lowered by mild chemical reduction involving ferric hydroxide-ferrous ion redox processes. V and Mo solubilities may be controlled by precipitation of ferrous vanadate or molybdate. Concentrations as low as 10−8.00 or 10−9.00 M are readily attainable for all these metals in oxygen-depleted...

W.F. McKenzie, A.H. Truesdell
1977, Geothermics (5) 51-61
The oxygen isotope compositions of dissolved sulfate and water from hot springs and shallow drillholes have been tested as a geothermometer in three areas of the western United States. Limited analyses of spring and borehole fluids and existing experimental rate studies suggest that dissolved sulfate and water are probably in...

Techniques for the conversion to carbon dioxide of oxygen from dissolved sulfate in thermal waters
N.L. Nehring, P.A. Bowen, A.H. Truesdell
1977, Geothermics (5) 63-66
The fractionation of oxygen isotopes between dissolved sulfate ions and water provides a useful geothermometer for geothermal waters. The oxygen isotope composition of dissolved sulfate may also be used to indicate the source of the sulfate and processes of formation. The methods described here for separation, purification and reduction of...

H.A. Kantrud, R. E. Stewart
1977, Journal of Wildlife Management (41) 243-253
Use of basin wetlands by breeding populations of 12 species of waterfowl was investigated in 1965 and during 1967-69 throughout the prairie pothole region of North Dakota. Data were obtained primarily by random sampling techniques. Of the total population occupying natural basin wetlands 55 percent occupied seasonal and 36 percent...
Changes in yellow perch (Perca flavescens) populations of Lake Michigan, 1954-75
LaRue Wells
1977, Journal of the Fisheries Research Board of Canada (34) 1821-1829
In the early and mid-1960s the abundance of yellow perch (Perca flavescens) in Lake Michigan declined abruptly. The decline began in the northern part of the lake and spread progressively southward. Circumstantial evidence suggests that the nonnative alewife (Alosa pseudoharengus), by interfering with perch reproduction, was the primary cause of...

Gary A. Wedemeyer, Nancy C. Nelson
1977, Journal of the Fisheries Research Board of Canada (34) 429-432
Ozone and chlorine inactivation curves were determined in three water types at 20 °C for the destruction of the fish pathogens Aeromonas salmonicida, the etiologic agent of furunculosis, and the enteric redmouth bacterium (ERM). In phosphate-buffered distilled water, 0.01 mg/ℓ ozone inactivated 103 cells/ml of ERM and A. salmonicida in 1/2 and 10 min, respectively. Chlorine at...
