Space, time, and the third dimension (model error)
Marshall E. Moss
1979, Water Resources Research (15) 1797-1800
The space-time tradeoff of hydrologic data collection (the ability to substitute spatial coverage for temporal extension of records or vice versa) is controlled jointly by the statistical properties of the phenomena that are being measured and by the model that is used to meld the information sources. The control exerted...
An algol program for dissimilarity analysis: a divisive-omnithetic clustering technique
J.C. Tipper
1979, Computers & Geosciences (5) 1-13
Clustering techniques are used properly to generate hypotheses about patterns in data. Of the hierarchical techniques, those which are divisive and omnithetic possess many theoretically optimal properties. One such method, dissimilarity analysis, is implemented here in ALGOL 60, and determined to be competitive computationally with most other methods. ?? 1979....
Photogrammetric portrayal of Mars topography
Sherman S.C. Wu
1979, Journal of Geophysical Research Solid Earth (84) 7955-7960
Special photogrammetric techniques have been developed to portray Mars topography, using Mariner and Viking imaging and nonimaging topographic information and earth-based radar data. Topography is represented by the compilation of maps at three scales: global, intermediate, and very large scale. The global map is a synthesis of topographic information obtained...
Geochemical and hydrologic considerations and the use of enthalpy-chloride diagrams in the prediction of underground conditions in hot-spring systems
R.O. Fournier
1979, Journal of Volcanology and Geothermal Research (5) 1-16
Thermal water ascending in a hot-spring system may cool by conduction of heat to the surrounding rock, by boiling, by mixing with cooler water, or by a combination of these processes. Complete or partial chemical reequilibration may occur as a result of this cooling. In spite of these complexities, in...
A new instrument system to investigate sediment dynamics on continental shelves
D.A. Cacchione, D.E. Drake
1979, Marine Geology (30) 299-312
A new instrumented tripod, the GEOPROBE system, has been constructed and used to collect time-series data on physical and geological parameters that are important in bottom sediment dynamics on continental shelves. Simultaneous in situ digital recording of pressure, temperature, light scattering, and light transmission, in combination with current velocity profiles...

L. L. Hood, P.J. Coleman Jr., C.T. Russell, D.E. Wilhelms
1979, Physics of the Earth and Planetary Interiors (20) 291-311
Properties of lunar crustal magnetization thus far deduced from Apollo subsatellite magnetometer data are reviewed using two of the most accurate presently available magnetic anomaly maps - one covering a portion of the lunar near side and the other a part of the far side. The largest single anomaly found...
Uranium transport in the Walker River Basin, California and Nevada
L. V. Benson, D. L. Leach
1979, Journal of Geochemical Exploration (11) 227-248
During the summer of 1976 waters from tributaries, rivers, springs and wells were sampled in the Walker River Basin. Snow and sediments from selected sites were also sampled. All samples were analyzed for uranium and other elements. The resulting data provide an understanding of the transport of uranium within...
Chemical and isotopic prediction of aquifer temperatures in the geothermal system at Long Valley, California
R.O. Fournier, M.L. Sorey, Robert H. Mariner, A.H. Truesdell
1979, Journal of Volcanology and Geothermal Research (5) 17-34
Temperatures of aquifers feeding thermal springs and wells in Long Valley, California, estimated using silica and Na-K-Ca geothermometers and warm spring mixing models, range from 160/dg to about 220??C. This information was used to construct a diagram showing enthalpy-chloride relations for the various thermal waters in the Long Valley region....
Determination of the optimum-size californium-252 neutron source for borehole capture gamma-ray analysis
F. E. Senftle, R.J. Macy, J.L. Mikesell
1979, Nuclear Instruments and Methods (158) 293-302
The fast- and thermal-neutron fluence rates from a 3.7 ??g 252Cf neutron source in a simulated borehole have been measured as a function of the source-to-detector distance using air, water, coal, iron ore-concrete mix, and dry sand as borehole media. Gamma-ray intensity measurements were made for specific spectral lines at...
Geochemical surveys in the United States in relation to health.
H. A. Tourtelot
1979, Philosophical Transactions of the Royal Society B: Biological Sciences (288) 113-125
Geochemical surveys in relation to health may be classified as having one, two or three dimensions. One-dimensional surveys examine relations between concentrations of elements such as Pb in soils and other media and burdens of the same elements in humans, at a given time. The spatial distributions of element concentrations...
Improved signal discrimination in tectonomagnetism: Discovery of a volcanomagnetic effect at Kilauea, Hawaii
P.M. Davis, F.D. Stacey, C.J. Zablocki, J.V. Olson
1979, Physics of the Earth and Planetary Interiors (19) 331-336
Cancellation of extraterrestrial magnetic disturbances by taking simple differences between total field readings at spaced stations is imperfect. It is shown that improvement is possible when three component observatory data are available from a single station in the general, but not necessarily immediate, vicinity of an array of total field...
Worth of data and natural disaster insurance
E. D. Attanasi, M.R. Karlinger
1979, Water Resources Research (15) 1763-1766
The Federal Government in the past has provided medical and economic aid to victims of earthquakes and floods. However, regulating the use of hazard-prone areas would probably be more efficient. One way to implement such land use regulation is through the national flood and earthquake insurance program. Because insurance firms...

Melvin Y. Ellis, editor(s)
1978, Report
Passage of the Coastal Zone Management Act of 1972 focused attention on the Nation's coastal land and water areas. As plans for more effective management of the coastal zone evolved, it soon became apparent that improved maps and charts of these areas were needed. This handbook was prepared with the...
NAWDEX: key to finding water data
Melvin D. Edwards
1978, Report
As our Nation's resources are developed, water will play an increasingly important role, both as a resource to be developed and as a resource to be protected. The proper development and protection of our water resources, however, will depend on adequate data on the quantity and quality of our water....

J.F. Patton
1978, Comparative Biochemistry and Physiology, Part A: Physiology (60) 21-24
1. The exponential removal of ICG from the plasma by the mallard duck liver made possible the measurement of fractional dye clearance (K), plasma volume (PV) and plasma clearance (PC).2. Values obtained for K (14.9%/min), PV (39.2 ml/kg) and PC (5.8 ml/min per kg) agreed with those obtained by other...

Leonard Gaydos, Willard L. Newland
1978, Journal of Research of the U.S. Geological Survey (6) 807-814
Landsat multispectral scanner digital data from four bands were analyzed using computers to produce land use and land cover information of the Puget Sound region, Wash., for use by agencies in that area. The data were first geographically registered to map coordinates. This registration enabled samples of known land cover...
