M. H. Podwysocki, J.W. Salisbury, O. D. Jones, D.L. Mimms
1983, Conference Paper
The paper is in abstract form. It discusses the Landsat-4 Thematic Mapper (TM), with its new near infrared bands centered at 1. 65 mu m and 2. 20 mu m and spatial resolution of 30 m, which has been used to distinguish rocks containing minerals having ferric-iron absorption bands in...
Maps for the nation: The current federal mapping establishment
Gary W. North
1983, Government Publications Review (10) 345-360
The U.S. Government annually produces an estimated 53,000 new maps and charts and distributes about 160 million copies. A large number of these maps are produced under the national mapping program, a decentralized Federal/State cooperative approach to mapping the country at standard scales. Circular A-16, issued by the Office of...
Dual extraction of R-mode and Q-mode factor solutions
D. Zhou, T. Chang, J.C. Davis
1983, Journal of the International Association for Mathematical Geology (15) 581-606
It is mathematically possible to extract both R-mode and Q-mode factors simultaneously (RQ-mode factor analysis)by invoking the Eckhart-Young theorem. The resulting factors will be expressed in measures determined by the form of the scalings that have been applied to the original data matrix. Unless the measures for both solutions are...
A quantitative comparison of Soil Development in four climatic regimes
J.W. Harden, E. M. Taylor
1983, Quaternary Research (20) 342-359
A new quantitative Soil Development Index based on field data has been applied to chronosequences formed under different climatic regimes. The four soil chronosequences, developed primarily on sandy deposits, have some numeric age control and are located in xeric-inland (Merced, Calif.), xeric-coastal (Ventura, Calif.), aridic (Las Cruces, N. Mex.), and...

J.A. Perkins, J.D. Sims
1983, Quaternary Research (20) 308-321
The thickness of varves in the sediments of Skilak Lake, Alaska, are correlated with the mean annual temperature (r = 0.574), inversely correlated with the mean annual cumulative snowfall (r = -0.794), and not correlated with the mean annual precipitation (r = 0.202) of the southern Alaska climatological division for...
Can the earth be dated from decay of its magnetic field?.
G. B. Dalrymple
1983, Journal of Geological Education (31) 124-133
Thomas G. Barnes, Emeritus Professor of Physics at the University of Texas, El Paso, and a creationist, argues that the geomagnetic field was created by unknown processes at the time of creation of the earth and has been decaying irreversibly and exponentially, with a half-life of about 1400 years,...
Landslide risk assessment
P. Lessing, C.P. Messina, R.F. Fonner
1983, Environmental Geology (5) 93-99
Landslide risk can be assessed by evaluating geological conditions associated with past events. A sample of 2,4 16 slides from urban areas in West Virginia, each with 12 associated geological factors, has been analyzed using SAS computer methods. In addition, selected data have been normalized to account for areal distribution...
Variation in survival and recovery rates of ring-necked ducks
Michael J. Conroy, Robert T. Eberhardt
1983, Journal of Wildlife Management (47) 127-137
Band recovery data were used to examine sex-specific, geographic, and temporal variations in survival and recovery rates of ring-necked ducks (Aythya collaris). Survival rates were higher (P < 0.05) for males than for females in the preseason-banded sample and in 2 of 3 postseason samples; recovery rates were higher (P...
Altitude of the top of the Matawan Group-Magothy Formation, Suffolk County, Long Island, New York
Richard K. Krulikas, E. J. Koszalka, Thomas P. Doriski
1983, Open-File Report 83-137
The Magothy aquifer, with its irregular surface and deeply eroded buried valleys, has become the major source of fresh water in most of Suffolk Country. With the availability of recent data from deep wells and test holes, refinement of the surface-altitude contours has been possible and resulted in substantial revision...
Improper use of regression equations in earth sciences
G. P. Williams
1983, Geology (11) 195-197
A regression equation used to estimate a variable is appropriately used only to estimate the dependent variable of that equation; the equation is inappropriately used when solved for an independent variable. Examples given here of this misuse of regression equations are based on...
Cenozoic structural history of selected areas in the eastern Great Basin, Nevada-Utah
R. Ernest Anderson
1983, Open-File Report 83-504
The Confusion Range structural trough (CRST) of west-central Utah predates the Oligocene rocks that are exposed along it. The northern part of the axial region of the CRST is complicated by structures that include reverse faults and associated folds, a large-amplitude mushroom fold, and belts of sharply flexed to overturned...
Euler-Lagrangian computation for estuarine hydrodynamics
Ralph T. Cheng
1983, Conference Paper, Numerical Methods in Laminar and Turbulent Flow, Proceedings of the International Conference
The transport of conservative and suspended matter in fluid flows is a phenomenon of Lagrangian nature because the process is usually convection dominant. Nearly all numerical investigations of such problems use an Eulerian formulation for the convenience that the computational grids are fixed in space and because the vast majority...
Use of reflectance spectra of native plant species for interpreting airborne multispectral scanner data in the East Tintic Mountains, Utah
N.M. Milton
1983, Economic Geology (78) 761-769
Representative spectra from three plant species were used to interpret the color components on a color ratio composite image. Most of the vegetation unit coincided with an altered rock unit, but many altered areas were not within the vegetation unit....
Assessment of water quality in canals of eastern Broward County, Florida, 1969-74

1982, Water-Resources Investigations Report 82-3
An intensive water-quality monitoring program was started in 1969 to determine the effects of man-induced contaminants on the water quality in the primary canal system of eastern Broward County, Florida. This report covers the first 6 years of the program and provides a data base that can be used to...
Effects of land use on surface-water quality in the East Everglades, Dade County, Florida
Bradley G. Waller

Gasometer: An inexpensive device for continuous monitoring of dissolved gases and supersaturation
G.R. Bouck
1982, Transactions of the American Fisheries Society (111) 505-516
The “gasometer” is a device that measures differential dissolved-gas pressures (δP) in water relative to barometric pressure (as does the “Weiss saturometer”), but operates continuously without human attention. The gasometer can be plumbed into a water-supply system and requires 8 liters/minute of water or more at 60 kilopascals. The...
