History of salmon in the Great Lakes, 1850-1970
John W. Parsons
1973, Technical Paper 68
This history of the salmon in the Great Lakes describes the decline and extinction of the Atlantic salmon (Salmo salar) in Lake Ontario in the 1800's; the failure to establish, by salmon culture, permanent or sizable populations of Atlantic or Pacific salmon in any of the Great Lakes in 1867-1965;...
Constitutive relations associated with the Mott-Smith distribution function
M. Nathenson, D. Baganoff
1973, Physics of Fluids (16) 2110-2115
It is shown that the distribution function assumed by Mott-Smith determines a unique relation between heat flux, stress, and fluid velocity given by q = (3/2)τu, i.e., it provides a constitutive relation for heat flux, and it also determines a simple expression for this ratio of third-order central moments Q...
Aspects of the magmatic geochemistry of bismuth
L. P. Greenland, D. Gottfried, E.Y. Campbell
1973, Geochimica et Cosmochimica Acta (37) 283-295
Bismuth has been determined in 74 rocks from a differentiated tholeiitic dolerite, two calc-alkaline batholith suites and in 66 mineral separates from one of the batholiths. Average bismuth contents, weighted for rock type, of the Great Lake (Tasmania) dolerite, the Southern California batholith...
Uranium concentration and distribution in six peridotite inclusions of probable mantle origin
E.L. Haines, R. E. Zartman
1973, Earth and Planetary Science Letters (20) 45-53
Fission-track activation was used to investigate uranium concentration and distribution in peridotite inclusions in alkali basalt from six localities. Whole-rock uranium concentrations range from 24 to 82 ng/g (1ng= 10−9g). Most of the uranium is uniformly distributed in the major silicate phases...
Ultrafiltration by a compacted clay membrane-II. Sodium ion exclusion at various ionic strengths
B.B. Hanshaw, T.B. Coplen
1973, Geochimica et Cosmochimica Acta (37) 2311-2327
Several recent laboratory studies and field investigations have indicated that shales and compacted clay minerals behave as semipermeable membranes. One of the properties of semipermeable membranes is to retard or prevent the passage of charged ionic species through the membrane pores while allowing relatively free movement of uncharged species. This...
Comparison of the magnetic properties of glass from Luna 20 with similar properties of glass from the Apollo missions
F. E. Senftle, A. N. Thorpe, C.C. Alexander, C.L. Briggs
1973, Geochimica et Cosmochimica Acta (37) 1053-1062
Magnetic susceptibility measurements have been made on four glass spherules and fragments from the Luna 20 fines; two at 300°K and two from 300°K to 4°K. From these data the magnetic susceptibility extrapolated to infinite field, the magnetization at low fields and also...
Mariner 9-Image processing and products
E.C. Levinthal, W.B. Green, J.A. Cutts, E.D. Jahelka, R.A. Johansen, M.J. Sander, J.B. Seidman, A.T. Young, L.A. Soderblom
1973, Icarus (18) 75-101
The purpose of this paper is to describe the system for the display, processing, and production of image-data products created to support the Mariner 9 Television Experiment. Of necessity, the system was large in order to respond to the needs of a large team of scientists with a broad scope...
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...
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...
Stress changes ahead of an advancing tunnel
J.F. Abel, F. T. Lee
1973, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (10) 673-697
Instrumentation placed ahead of three model tunnels in the laboratory and ahead of a crosscut driven in a metamorphic rock mass detected stress changes several tunnel diameters ahead of the tunnel face. Stress changes were detected 4 diameters ahead of a model tunnel drilled into nearly elastic acrylic, 2·50 diameters...
Statistical recognition of late Cretaceous cyclic sedimentation by means of calcareous nannofossil population studies
I.R. Mayers, T.R. Worsley
1973, Palaeogeography, Palaeoclimatology, Palaeoecology (13) 81-90
The relative abundance of calcareous nannofossil taxa in a sequence of samples collected from a continuous Upper Maastrichtian section in Alabama has been analyzed using statistical techniques. Results indicate that an increase of arbitrarily chosen long-ranging forms can be represented by a slowly...
