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...
Fish viruses: Buffers and methods for plaquing eight agents under normal atmosphere
K. Wolf, M. C. Quimby
1973, Applied Microbiology (25) 659-664
A universal procedure was sought for plaque assay of eight fish viruses (bluegill myxovirus, channel catfish virus, eel virus, Egtved virus, infectious hematopoietic necrosis virus, infectious pancreatic necrosis virus, lymphocystis virus, and the agent of spring viremia of carp (Rhabdovirus carpio), in dish cultures of various fish cells. Eagle minimal...
Inorganic chemical investigation by x-ray fluorescence analysis: The Viking Mars Lander
P. Toulmin III, A. K. Baird, B. C. Clark, Klaus Keil, H. J. Rose Jr.
1973, Icarus (20) 153-178
The inorganic chemical investigation added in August 1972 to the Viking Lander scientific package will utilize an energy-dispersive X-ray fluorescence spectrometer in which four sealed, gas-filled proportional counters will detect X-rays emitted from samples of the Martian surface materials irradiated by X-rays from radioisotope sources (55Fe and 109Cd). The output...
Petrography and stratigraphy of glacial drift, Mesabi-Vermilion Iron Range area, northeastern Minnesota
Thomas C. Winter, R. D. Cotter, H. L. Young
1973, Bulletin 1331-C
Glacial deposits in the Mesabi-Vermilion Iron Range area consist of four major till units and associated glaciofluvial sediments. Particle-size data and pebble, heavy-mineral, clay-mineral, and percentage-soluble content were used in addition to field description of color and texture to describe and correlate the drift units. The lowermost till unit, basal till,...
Radial particle-size segregation during packing of particulates into cylindrical containers
C.D. Ripple, R.V. James, J. Rubin
1973, Powder Technology (8) 165-175
In a series of experiments, soil materials were placed in long cylindrical containers, using various packing procedures. Soil columns produced by deposition and simultaneous vibratory compaction were dense and axially uniform, but showed significant radial segregation of particle sizes. Similar results were obtained with deposition and simultaneous impact-type compaction when...
Floods in New York, 1971
F. Luman Robison
1973, Report
This report, for the calendar year 1971, was prepared at the request of the New York State Department of Transportation under provisions of an agreement between the New York State Department of Environmental Conservation and the U.S. Geological Survey fore a cooperative statewide program investigate the water resources of the...
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...
A method to determine waterfowl shooting distances
D.A. Davenport, G.A. Sherwood, H. W. Murdy
1973, Wildlife Society Bulletin (1) 101-105
Long-range shooting at ducks and geese frequently results in a high crippling loss, unretrieved birds and frustrated hunters. A principal problem has been the general inability of hunters or observers to properly judge distance of birds. This paper describes a reasonably accurate method developed to determine shooting distances to geese....
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...
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...
Developing a state water plan: Ground-water conditions in Utah, spring of 1972
C.T. Sumison, L.J. Bjorklund, L. J. McGreevy, E.L. Bolke, R. W. Mower, L. R. Herbert, L. L. Miller, R.G. Butler, D. B. Adams, G. W. Sandberg
1972, Cooperative Investigations Report 10
This report is the ninth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series are prepared cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources and are designed to provide data to enable interested parties such as legislators, administrators,...
Principal facts for gravity stations in the area north of the Grand Canyon in Arizona
Peter Popenoe
1972, Report
Observed gravity values, station location, terrain corrections, and Bouguer gravity data are provided in tabular form for approximately 610 gravity observations in northern Arizona. These data were used in preparation of - - Popenoe, Peter, 1968, Complete Bouguer gravity anomaly map of the area north of the Grand Canyon in...
Orbital-science investigation: Part O: regional variations in the magnitude of heiligenschein and causal connections
Robert L. Wildey
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
Approximately 35 reasonably good candidates for specialized photometric studies were found during a thorough examination of the frames exposed by the Apollo 15 metric camera. Of these, the majority was of value in heiligenschein studies (refs. 25-36 to 25-38). A few were of value for limited-interval delineation of the photometric...
