Recent developments in the U. S. Geological Survey's Landsat image mapping program
Frederick S. Brownworth, Wayne G. Rohde
1986, Conference Paper, Technical Papers of the American Society of Photogrammetry, Fall Technical Meeting
At the 1984 ASPRS-ACSM Convention in Washington, D. C. a paper on 'The Emerging U. S. Geological Survey Image Mapping Program' was presented that discussed recent satellite image mapping advancements and published products. Since then Landsat image mapping has become an integral part of the National Mapping Program. The Survey...

Movement and fate of creosote waste in ground water, Pensacola, Florida; U.S. Geological Survey toxic waste-ground-water contamination program
Bernard J. Franks
H.C. Mattraw Jr., editor(s)
1986, Water Supply Paper 2285
Ground- and surface-water contamination by pesticides used in the wood-preserving industry is widespread in the United States. Pine poles were treated with wood preservatives from 1902 to 1981 at a creosote works near Pensacola, Florida. Diesel fuel, creosote, and pentachlorophenol were discharged to two unlined impoundments that had a direct...

Mapping nuclear craters on Enewetak Atoll, Marshall Islands
John C. Hampson
1986, Conference Paper, Proceedings International Symposium on Marine Positioning
In 1984, the U.S. Geological Survey conducted a detailed geologic analysis of two nuclear test craters at Enewetak Atoll, Marshall Islands, on behalf of the Defense Nuclear Agency. A multidisciplinary task force mapped the morphology, surface character, and subsurface structure of two craters, OAK and KOA. The field mapping techniques include...
Nd, O and Sr isotopic constraints on the origin of Precambrian rocks, southern Black Hills, South Dakota
R.J. Walker, G. N. Hanson, J. J. Papike, J. R. O’Neil
1986, Geochimica et Cosmochimica Acta (50) 2833-2846
The Nd, O and Sr isotopic characteristics of Precambrian metasedimentary, metavolcanic and granitic rocks from the Black Hills of South Dakota are examined. Two late-Archean granites (2.5-2.6 Ga) have Tdm ages of 3.05 and 3.30 Ga, suggesting that at least one of the granites was derived through the melting of significantly...
Applications of UThPb isotope systematics to the problems of radioactive waste disposal
J. S. Stuckless
1986, Chemical Geology (55) 215-225
Concentrations of U, Th and Pb, and the isotopic composition of Pb for whole-rock samples of granitoids show: (1) that open-system behavior is nearly universal in the surface and near-surface environment; and (2) that elemental mobility is possible to depths of several hundred meters. Several identified or at least postulated...
Optical reflection from planetary surfaces as an operator-eigenvalue problem
R.L. Wildey
1986, Earth, Moon and Planets (36) 103-116
The understanding of quantum mechanical phenomena has come to rely heavily on theory framed in terms of operators and their eigenvalue equations. This paper investigates the utility of that technique as related to the reciprocity principle in diffuse reflection. The reciprocity operator is shown to be unitary and Hermitian; hence,...
Manganese biogeochemistry in a small Adirondack forested lake watershed
James B. Shanley
1986, Water Resources Research (22) 1647-1656
In September and October 1981, manganese (Mn) concentrations and pH were intensively monitored in a small forested lake watershed in the west-central Adirondack Mountains, New York, during two large acidic storms (each ∼5 cm rainfall, pH 4.61 and 4.15). The data were evaluated to identify biogeochemical pathways of Mn and to assess...
Effects of the 1906 Earthquake on the Bald Hill Outlet System, San Mateo County, California
Earl H. Pampeyan
1986, Bulletin of the Association of Engineering Geologists (23) 197-208
Following the earthquake of April 18, 1906, it was discovered that a brick forebay and other parts of the reservoir outlet system were in the slip zone of the San Andreas fault. The original outlet through which water was directed to San Francisco consisted of two tunnels joined at the...
Correlation between electron spin resonance spectra and oil yield in eastern oil shales
M. Choudhury, K.F. Rheams, J.W. Harrell Jr.
1986, Fuel (65) 1028-1029
Organic free radical spin concentrations were measured in 60 raw oil shale samples from north Alabama and south Tennessee and compared with Fischer assays and uranium concentrations. No correlation was found between spin concentration and oil yield for the complete set of samples. However, for a 13 sample set taken...
A soil catena on schist in northwestern California
D. C. Marron, J.H. Popenoe
1986, Geoderma (37) 307-324
Soil characteristics in a small steepland watershed underlain by schist in a rainy, tectonically active area in northwestern California show close associations with drainage-basin position and slope characteristics. Five soil-topography units based on these associations are defined in the study watershed. Spatial relationships of soil series, and patterns of soil...
Effect of ground-water recharge on configuration of the water table beneath sand dunes and on seepage in lakes in the sandhills of Nebraska, U.S.A.
T. C. Winter
1986, Journal of Hydrology (86) 221-237
Analysis of water-level fluctuations in about 30 observation wells and 5 lakes in the Crescent Lake National Wildlife Refuge in the sandhills of Nebraska indicates water-table configuration beneath sand dunes in this area varies considerably, depending on the configuration of the topography of the dunes. If the topography of an...
Isolation and detection of Giardia cysts from water using direct immunofluorescence
Stephen K. Sorenson, John L. Riggs, Peter D. Dileanis, Thomas J. Suk
1986, Water Resources Bulletin (22) 843-845
A water‐sampling apparatus used for the isolation and detection of Giardiacysts in water has been designed and tested. The sampling apparatus uses one of a variety of pumps or waterline pressure to move water through a filter. Two of the optional pumps are lightweight enough to make the apparatus portable and...
Nonlinear-regression groundwater flow modeling of a deep regional aquifer system
Richard L. Cooley, Leonard F. Konikow, Richard L. Naff
1986, Water Resources Research (22) 1759-1778
A nonlinear regression groundwater flow model, based on a Galerkin finite-element discretization, was used to analyze steady state two-dimensional groundwater flow in the areally extensive Madison aquifer in a 75,000 mi2 area of the Northern Great Plains. Regression parameters estimated include intrinsic permeabilities of the main aquifer and separate lineament zones,...
Changing concepts of geologic structure and the problem of siting nuclear reactors: Examples from Washington State
R. W. Tabor
1986, Geology (14) 738-742
The conflict between regulation and healthy evolution of geological science has contributed to the difficulties of siting nuclear reactors. On the Columbia Plateau in Washington, but for conservative design of the Hanford reactor facility, the recognition of the little-understood Olympic-Wallowa lineament as a...
Effect of sediment depth and sediment type on the survival of Vallisneria americana Michx grown from tubers
Nancy B. Rybicki, Virginia Carter
1986, Aquatic Botany (24) 233-240
Sedimentation resulting from storms may have been one of the reasons for the elimination of submersed aquatic vegetation from the tidal Potomac River in the late 1930's. Laboratory studies were conducted to investigate the effects of different depths of overlying sediment and composition of sediment on the survival of Vallisneria americana Michx...

1986, Conference Paper
MAPGEN is a software system that facilitates production of cartographic displays in the research and production environment. The system generates a set of metagraphic overlays of application-defined geographical information that can be aggregated in any combination for display without reprocessing the original data. An overview of the control files, available...
