Results of a modeling workshop concerning economic and environmental trends and concomitant resource management issues in the Mobile Bay area
David B. Hamilton, Austin K. Andrews, Gregor T. Auble, Richard A. Ellison, Richard A. Johnson, James E. Roelle, Michael J. Staley
1982, Report
During the past decade, the southern regions of the U.S. have experienced rapid change which is expected to continue into the foreseeable future. Growth in population, industry, and resource development has been attributed to a variety of advantages such as an abundant and inexpensive labor force, a mild climate,...

Removing tidal-period variations from time-series data using low-pass digital filters
Roy A. Walters, Cynthia Heston
1982, Journal of Physical Oceanography (12) 112-115
Several low-pass, digital filters are examined for their ability to remove tidal Period Variations from a time-series of water surface elevation for San Francisco Bay. The most efficient filter is the one which is applied to the Fourier coefficients of the transformed data, and the filtered data recovered through an...
Population modeling for furbearer management
Douglas H. Johnson
G.C. Sanderson, editor(s)
1982, Book chapter, Midwest Furbearer Management. N. Central Sec., Central Mountains and Plains Sec., and KS.
The management of furbearers has become increasingly complex as greater demands are placed on their populations. Correspondingly, needs for information to use in management have increased. Inadequate information leads the manager to err on the conservative side; unless the size of the 'harvestable surplus' is known, the population cannot be...
Techniques of trend analysis for monthly water quality data
Robert M. Hirsch, James R. Slack, Richard A. Smith
1982, Water Resources Research (18) 107-121
Some of the characteristics that complicate the analysis of water quality time series are non-normal distributions, seasonality, flow relatedness, missing values, values below the limit of detection, and serial correlation. Presented here are techniques that are suitable in the face of the complications listed above for the exploratory analysis of...
Phase relations in the system NaCl-KCl-H2O. Part I: Differential thermal analysis of the NaCl-KCl liquidas at 1 atmosphere and 500, 1000, 1500, and 2000 bars
I.-M. Chou
1982, Geochimica et Cosmochimica Acta (46) 1957-1962
A simple differential thermal analysis (DTA) technique has been developed to study phase relations of various chemical systems at elevated pressures and temperatures. The DTA system has been calibrated against known melting temperatures in the system NaCl-KCl. Isobaric sections of the liquidus in the system NaCl-KCl have been determined at...
On the tectonics and metallogenesis of West Africa: a model incorporating new geophysical data
David A. Hastings
1982, Geoexploration (20) 295-327
The gold, diamond and manganese deposits of Ghana have attracted commercial interest, but appropriate geophysical data to delineate the tectonic setting of these and other deposits have been lacking until recently. Recent gravity surveys, however, now cover about 75% of the country. When used in a synthesis of the sometimes...
Chemical and light-stable isotope characteristics of waters from the Raft River geothermal area and environs, Cassia County, Idaho; Box Elder County, Utah
M. Nathenson, N.L. Nehring, E. G. Crosthwaite, R.S. Harmon, C. Janik, J. Borthwick
1982, Geothermics (11) 215-237
Chemical and light-stable isotope data are presented for water samples from the Raft River geothermal area and environs. On the basis of chemical character, as defined by a trilinear plot of per cent milliequivalents, and light-stable isotope data, the waters in the geothermal area can be divided into waters that...
Comparison of techniques for estimating annual lake evaporation using climatological data
M.E. Andersen, H.E. Jobson
1982, Water Resources Research (18) 630-636
Mean annual evaporation estimates were determined for 30 lakes by use of a numerical model (Morton, 1979) and by use of an evaporation map prepared by the U.S. Weather Service (Kohler et al., 1959). These estimates were compared to the reported value of evaporation determined from measurements on each lake....
Estimating irrigation water use and withdrawal of ground water on the High Plains, U.S.A.
J. R. Wray
1982, Advances in Space Research (2) 127-129
In four decades following the Dust Bowl days of the 1930's, extensive areas of dry farming and rangeland on the semi-arid U.S. High Plains were transformed into a vast region of irrigated oases, producing meat and grain for much of the world. The agricultural economy has experienced such rapid growth...
The UThPb age of equilibrated L chondrites and a solution to the excess radiogenic Pb problem in chondrites
D.M. Unruh
1982, Earth and Planetary Science Letters (58) 75-94
U, Th, and Pb analyses of whole-rock and troilite separates from seven L chondrites suggest that the excess radiogenic Pb relative to U and the large variations in PbPb model ages commonly observed in chondritic meteorites are largely due to terrestrial Pb contamination induced prior to...
Worth of geophysical data in natural- disaster- insurance rate setting.
E. D. Attanasi, M.R. Karlinger
1982, Journal of Applied Meteorology and Climatology (21) 453-460
Insurance firms that offer natural-disaster insurance base their rates on available information. The benefits from collecting additional data and incorporating this information to improve parameter estimates of probability distributions that are used to characterize natural-disaster events can be determined by computing changes in premiums as a function of additional data....
Aminostratigraphy and faunal correlations of late Quaternary marine terraces, Pacific Coast, USA
G. L. Kennedy, K. R. Lajoie, J.F. Wehmiller
1982, Nature (299) 545-547
Recent studies using the extent of racemization of amino acids to date fossil mollusc shells in the Arctic1, the British Isles2 and on the Atlantic3,4 and Pacific5-13 coasts of North America have relied mainly on theoretical kinetic models of racemization. Ages generated in this fashion are highly model dependent and...
An analysis of input errors in precipitation-runoff models using regression with errors in the independent variables
Brent M. Troutman
1982, Water Resources Research (18) 947-964
Errors in runoff prediction caused by input data errors are analyzed by treating precipitation-runoff models as regression (conditional expectation) models. Independent variables of the regression consist of precipitation and other input measurements; the dependent variable is runoff. In models using erroneous input data, prediction errors are inflated and estimates of...
Geomagnetic local and regional harmonic analyses
L.R. Alldredge
1982, Journal of Geophysical Research Solid Earth (87) 1921-1926
Procedures are developed for using rectangular and cylindrical harmonic analyses in local and regional areas. Both the linear least squares analysis, applicable when component data are available, and the nonlinear least squares analysis, applicable when only total field data are available, are treated. When component data are available, it is...
Estimation of earthquake source parameters by the inversion of waveform data: synthetic waveforms
S.A. Sipkin
1982, Physics of the Earth and Planetary Interiors (30) 242-259
Two methods are presented for the recovery of a time-dependent moment-tensor source from waveform data. One procedure utilizes multichannel signal-enhancement theory; in the other a multichannel vector-deconvolution approach, developed by Oldenburg (1982) and based on Backus-Gilbert inverse theory, is used. These methods have the advantage of being extremely flexible; both...

Earthquake location in island arcs
E.R. Engdahl, J. W. Dewey, K. Fujita
1982, Physics of the Earth and Planetary Interiors (30) 145-156
A comprehensive data set of selected teleseismic P-wave arrivals and local-network P- and S-wave arrivals from large earthquakes occurring at all depths within a small section of the central Aleutians is used to examine the general problem of earthquake location in island arcs. Reference hypocenters for this special data set...
Acid rain, air pollution, and tree growth in southeastern New York
L.J. Puckett
1982, Journal of Environmental Quality (11) 376-381
Whether dendroecological analyses could be used to detect changes in the relationship of tree growth to climate that might have resulted from chronic exposure to components of the acid rain-air pollution complex was determined. Tree-ring indices of white pine (Pinus strobus L.), eastern hemlock (Tsuga canadensis (L.) Cart.), pitch pine...
