The role of the Bureau of Sport Fisheries and Wildlife in the Great Lakes
F. Eugene Hester
1973, Conference Paper, Proceedings of the First Federal Conference on the Great Lakes
Ecological blunders of man, such as timber exploitation, draining of wetlands, construction of canals and dams, and pollution have been mainly responsible for serious environmental degradation and catastrophic losses of fish and wildlife values in the Great Lakes Basin. Consequently, the major emphasis of the Bureau of Sport Fisheries and...
Radiochemical monitoring of water after the Cannikin event, Amchitka Island, Alaska, July 1972
Wilbur C. Ballance, L.J. Schroder
1973, Report
The U.S. Geological Survey established a sampling program on Amchitka Island in 1967 in cooperation with the U.S . Atomic Energy Commission. Water samples are analyzed routinely for tritium, gross alpha, and gross beta/gamma content, Frequency of sampling was semiannually prior to Cannikin and has been bimonthly since the Cannikin...
Radiochemical monitoring of water after the Cannikin event, Amchitka Island, Alaska, October 1972
L.J. Schroder, Wilbur C. Ballance
1973, Report
The U.S. Geological Survey collected water samples from Arnchitka Island, Alaska, during October 1972. Tritium determinations were made on all samples collected and gross alpha and gross beta/gamma determinations were made on 41 samples. The gross alpha and gross beta determinations when compared with previously determined ranges for fresh waters...
Hydraulic tests in hole UAe-3, Amchitka Island, Alaska
Wilbur C. Ballance
1973, Report
Inflatable straddle packers were used to isolate and test selected intervals in hole UAe-3. Packer seats were poor in the uncased part of the hole because of unstable wall conditions, and leakage around packers occurred during some tests. However, leakage generally was slight, as shown on pressure-gage charts, and had...
Summary of chemical and radiochemical monitoring of water for the Cannikin event, Amchitka Island, Alaska, fiscal year 1972
L.J. Schroder, Wilbur C. Ballance
1973, Report
An increased dissolved-solids content was found immediately after the Cannikin event (November 6, 1971) at most of 10 locations in a water-sampling network established in 1967 and revised in September 1971. The observed dissolved-solids content increase was within the seasonal range that has been observed at these locations. No measurable increase...
Biochemical monitoring of water after the Cannikin event, Amchitka Island, Alaska, August 1973
Wilbur C. Ballance
1973, Report
Radiochemical data from the Amchitka Island study area were obtained from water samples collected by the U.S. Geological Survey during August 1973. Tritium determinations were made on 86 samples collected and gross alpha and gross beta/gamma determinations were made on 38 samples. The range of data for these samples was...

18O 16O ratios in cherts associated with the saline lake deposits of East Africa
J. R. O’Neil, R. L. Hay
1973, Earth and Planetary Science Letters (19) 257-266
The cherts formed from sodium silicate precursors in East African saline, alkaline lakes have δ18O values ranging from 31.1 to 44.1. The δ18O values correlate in general with lake salinities as inferred from geologic evidence, indicating that most chert was formed...
Simultaneous flow of water and solutes through geological membranes-I. Experimental investigation
Y.K. Kharaka, F.A.P. Berry
1973, Geochimica et Cosmochimica Acta (37) 2577-2603
The relative retardation by geological membranes of cations and anions generally present in subsurface waters was investigated using a high pressure and high temperature ‘filtration cell’. The solutions were forced through different clays and a disaggregated shale subjected to compaction pressures up to...
Effect of sea water interaction on strontium isotope composition of deep-sea basalts
Dasch E. Julius, C. E. Hedge, J. Dymond
1973, Earth and Planetary Science Letters (19) 177-183
Analyses of rim-to-interior samples of fresh tholeiitic pillow basalts, deuterically altered holocrystalline basalts, and older, weathered tholeiitic basalts from the deep sea indicate that 87Sr/86Sr ratios of the older basalts are raised by low temperature interaction with strontium dissolved in sea water. 87Sr/86Sr correlates...
An empirical NaKCa geothermometer for natural waters
R.O. Fournier, A.H. Truesdell
1973, Geochimica et Cosmochimica Acta (37) 1255-1275
An empirical method of estimating the last temperature of water-rock interaction has been devised. It is based upon molar Na, K and Ca concentrations in natural waters from temperature environments ranging from 4 to 340°C. The data for most geothermal waters cluster near a straight line when plotted as the...
Production of superheated steam from vapor-dominated geothermal reservoirs
A.H. Truesdell, D. E. White
1973, Geothermics (2) 154-173
Vapor-dominated geothermal systems such as Larderello, Italy, The Geysers, California, and Matsukawa, Japan yield dry or superheated steam when exploited. Models for these systems are examined along with production data and the thermodynamic properties of water, steam and rock. It is concluded that...

E. Mazor, R.O. Fournier
1973, Geochimica et Cosmochimica Acta (37) 515-525
Water and gas samples from research wells in hydrothermal areas of Yellowstone National Park, U.S.A., have been mass spectrometrically analyzed for their rare gas contents and isotopic composition. In agreement with previous findings, the rare gases have been found to originate from infiltrating...
Thermal conductivity of carbonate rocks
J. Thomas Jr., R.R. Frost, R.D. Harvey
1973, Engineering Geology (7) 3-12
The thermal conductivities of several well-defined carbonate rocks were determined near 40°C. Values range from 1.2 W m−1C−1 for a highly porous chalk to 5.1 W m−1C−1 for a dolomite. The thermal conductivity of magnesite (5.0) is at the high end of the range, and that for Iceland Spar Calcite (3.2) is near the...

Extraction and concentration of organic solutes from water
Marvin C. Goldberg, Lewis L. DeLong, Mark Sinclair
1973, Analytical Chemistry (45) 89-93
A continuous extraction apparatus is described. It extracts and simultaneously concentrates organic solutes from water. Any immiscible solvent can be used in this apparatus if the solute will partition between the solvent and water. A concentration factor of up to 105 is obtained with this technique. The dipole moment difference...
