Response of douglas fir (Pseudotsuga menziesii) to uraniferous groundwater in a small glaciated drainage, Northeastern Washington State
R. A. Zielinski, R.R. Schumann
1987, Journal of Geochemical Exploration (27) 281-298
Douglas fir trees and associated soils were sampled from the slopes of a small (∼4 km2) drainage basin in northeastern Washington to investigate the biogeochemical response to locally uraniferous groundwater. Uranium is preferentially incorporated in needles and twigs compared to larger...
Wind energy development in California, USA
H. Wilshire, D. Prose
1987, Environmental Management (11) 13-20
Windfarms have been developed rapidly in California in the last few years. The impetus has been a legislated goal to generate 10% of California's electricity by windpower by the year 2000, and generous state and federal tax incentives. Windpower is promoted as environmentally benign, which it is in traditional uses....
Provenance studies by fission-track dating of zircon-etching and counting procedures
N. D. Naeser, P.K. Zeitler, C. W. Naeser, P.F. Cerveny
1987, International Journal of Radiation Applications and Instrumentation. Part D. Nuclear Tracks and Radiation Measurements (13) 121-126
In sedimentary rocks that have not been heated to high enough temperatures to anneal fission tracks in zircon (greater than ≈ 160°C), fission-track ages of individual detrital zircon grains provide valuable information about the source rocks eroded to form the sediments. The success of such studies depends, however, on the...

Gulf trough: The Atlantic connection
Peter Popenoe, Vernon J. Henry, Faisal M. Idris
1987, Geology (15) 327-332
Analyses of seismic reflection profiles and stratigraphic data indicate a continuation of the Gulf trough trend across eastern South Carolina and offshore between Cape Fear and Cape Hatteras, North Carolina. Seismic profiles show a linear northeast-trending zone of nondeposition and erosion and areas...
Presence and potential significance of aromatic-ketone groups in aquatic humic substances
J.A. Leenheer, M. A. Wilson, Ronald L. Malcolm
1987, Organic Geochemistry (11) 273-280
Aquatic humic- and fulvic-acid standards of the International Humic Substances Society were characterized, with emphasis on carbonyl-group nature and content, by carbon-13 nuclear-magnetic-resonance spectroscopy, proton nuclear-magnetic-resonance spectroscopy, and infrared spectroscopy. After comparing spectral results of underivatized humic and fulvic acids with spectral results of chemically modified derivatives, that allow improved...
Implications of the northwestwardly younger age of the volcanic rocks of west-central California: Alternative Interpretation
Richard G. Stanley
1987, GSA Bulletin (98) 612-614
Fox and others (1985) have made an important contribution to our understanding of iihe evolution of the Mendocino triple junction and the San Andreas transform. They have summarized a large amount of data on the ages and distribution of volcanic centers along the central California coast; their summary clearly shows...
Ground-water flow and shallow-aquifer properties in the Rio Grande inner valley south of Albuquerque, Bernalillo County, New Mexico
K. D. Peter
1987, Water-Resources Investigations Report 87-4015
The purpose of this investigation was to describe the water table configuration and its temporal variations, estimate aquifer properties, and evaluate the interaction of groundwater and surface water in the inner valley of the Rio Grande in southern Albuquerque, New Mexico, where groundwater contamination is a continuing concern. The upper...
Generalized potentiometric surface of the aquifers in the Cockfield Formation, southeastern Arkansas, spring 1980
D. J. Ackerman
1987, Water-Resources Investigations Report 87-4212
This map shows the generalized contours of the altitude of water levels in wells completed in the Cockfield Formation in southeastern Arkansas for 1980. Most water levels used in constructing the map were made in the spring of 1980. However, in parts of the State water levels from the spring...
Generalized potentiometric surface of the Sparta-Memphis aquifer, eastern Arkansas, spring 1980
D. J. Ackerman
1987, Water-Resources Investigations Report 87-4282
A map shows generalized contours of the altitude of water levels for wells completed in the Sparta-Memphis aquifer in eastern Arkansas. Most water-level measurements used in constructing the map were from the spring of 1980, but supplemental measurements from other years indicated no long-term change in water levels. Hydrographs for...
Roosevelt elk density in old-growth forests of Olympic National Park
D.B. Houston, Bruce B. Moorhead, R.W. Olson
1987, Northwest Science (61) 220-225
We explored the feasibility of censusing Roosevelt elk from a helicopter in the dense old growth forests of Olympic National Park. WA. Mean observed densities ranged from 8.0-11.6 elk/km2, with coefficients of variation averaging 19.9 percent. A provisional sightability factor of 74 percent suggested that actual mean densities ranged from...

Responses of three prairie ground squirrel species, Spermophilus franklinii, S. richardsonii, and S. tridecemlineatus, to duck eggs
A.B. Sargeant, M.A. Sovada, R. J. Greenwood
1987, Canadian Field-Naturalist (101) 95-97
Franklin's Ground Squirrels (Spermophilus franklinii) preyed on eggs in 29 of 30 tests in which they were exposed to two Mallard (Anas platyrhynchos) or two Blue-winged Teal (A. discors) eggs and their discovery of eggs was confirmed. No Richardson's (S. richardsonii) or Thirteen-lined (S. tridecemlineatus) ground squirrels preyed on eggs...
BOREHOLE NEUTRON ACTIVATION: THE RARE EARTHS.
J.L. Mikesell, F. E. Senftle
1987, IEEE Transactions on Nuclear Science (35)
Neutron-induced borehole gamma-ray spectroscopy has been widely used as a geophysical exploration technique by the petroleum industry, but its use for mineral exploration is not as common. Nuclear methods can be applied to mineral exploration, for determining stratigraphy and bed correlations, for mapping ore deposits, and for studying mineral concentration...
