1984, Analytical Chemistry (56) 283-288
An inductively coupled Ar plasma (ICP), generated in a lowflow torch, was investigated by the simplex optimization technique for simultaneous, multielement, atomic emission spectrometry (AES). The variables studied included forward power, observation height, gas flow (outer, intermediate, and nebulizer carrier) and sample uptake rate. When the ICP was operated at...

Status and future of satellite image mapping: Based on experience of the U.S. Geological Survey
Alden P. Colvocoresses
Cook Jerald J., editor(s)
1984, Conference Paper, Proceedings of the International Symposium on Remote Sensing of Environment
Space systems now provide data in basically orthographic form which greatly simplifies the production of the image map. Moreover, the multispectral capability of space systems facilitates the use of the color mode when compared to aerial photography. Digital graphical information systems are now being developed on a global basis and...
Adsorption of goethite onto quartz and kaolinite
M. C. Goldberg, Eugene R. Weiner, P. M. Boymel
1984, Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases (80) 1491-1498
The adsorption of colloidal goethite onto quartz and kaolinite substrates has been studied as a function of pH and NaCl concentration. Goethite adsorption was measured quantitatively by Fourier-transform infrared spectroscopy. The results indicate that adsorption onto both substrates is due primarily to coulombic forces; however, the pH dependence of adsorption...
Seismic reflection studies of sinkholes and limestone dissolution features on the northeastern Florida shelf
Peter Popenoe, F. A. Kohout, F.T. Manheim
Beck Barry F., editor(s)
1984, Conference Paper, Sinkholes: Their geology, engineering, and environmental impact
High-resolution seismic-reflection profiles show that the shelf off northern Florida is underlain by solution deformed limestone of Oligocene, Eocene, Paleocene and late Cretaceous age. Dissolution and collapse features are widely scattered. They are expressed in three general forms: as sinkholes that presently breach the sea floor, such as Red Snapper...

1984, Professional Paper 1375
Geologic mapping and potassium-argon dating by R. L. Detterman, F. H. Wilson, J. E. Case, and Nora Shew in the Ugashik and western part of the Karluk quadrangles have shown that the Eocene and Oligocene volcanic arc continues into these quadrangles from the south in the Chignik and Sutwik Island...
Comparison of nonlinear least squares and log transformation procedures for calculating volatilization coefficients
R. E. Rathbun, D. Y. Tai
1984, Chemosphere (13) 715-730
A nonlinear least squares procedure and a log transformation procedure for calculating first-order rate coefficients from experimental concentration-versus-time data were compared using laboratory measurements of the volatilization from water of 1,1,1-trichloroethane and 1,2-dichloroethane and the absorption of oxygen by water. Ratios of the nonlinear least squares to log transformation volatilization...

Breeding biology of Pacific white-fronted geese
Craig R. Ely, Dennis G. Raveling
1984, Journal of Wildlife Management (48) 823-837
Nesting ecology of Pacific white-fronted geese (Anser albifrons frontalis) was studied on a 9.9-km2 area on the Yukon-Kuskokwim (Y-K) Delta, Alaska, during 1977-79. Availability of nesting habitat varied considerably among years because of differences in time of snow- and icemelt. Mean clutch size was 3.7 eggs in the late spring...

The Jeanie Point complex revisited
Julie A. Dumoulin, Marti L. Miller
1984, Circular 868
The so-called Jeanie Point complex is a distinctive package of rocks within the Orca Group, a Tertiary turbidite sequence. The rocks crop out on the southeast coast of Montague Island, Prince William Sound, approximately 3 km northeast of Jeanie Point (loc. 7, fig. 44). These rocks consist dominantly of fine-grained...

Streamflow gain-and-loss and suspended-sediment characteristics of the South Platte River and three irrigation canals near Fort Morgan, Colorado
B. C. Ruddy
1984, Water-Resources Investigations Report 84-4220
A 2-year study during 1982-83 was made to document the streamflow gain-and-loss and suspended sediment characteristics of the South Platte River, Fort Morgan Canal, Upper Platte and Beaver Canal, and the Lower Platte and Beaver Canal near Fort Morgan, Colorado, prior to possible construction of the proposed Narrows Reservoir. Six...
Potential effects of surface coal mining on the hydrology of the West Otter area, Ashland and Birney-Broadus coal fields, southeastern Montana
N. E. McClymonds
1984, Water-Resources Investigations Report 84-4087
Shallow aquifers exist primarily within the Tongue River Member of the Paleocene Fort Union Formation and within valley alluvium. Sandstone beds are the principal aquifers for domestic supply and livestock watering, with the Knobloch coal bed being a secondary source of supply. Surface-water resources consist principally of perennial flow in...
Hydrologic analysis of the High Plains aquifer system in Box Butte County, Nebraska
R. A. Pettijohn, Hsiu-Hsiung Chen
1984, Water-Resources Investigations Report 84-4046
During the past 40 years, pumpage of ground water for irrigation from the High Plains aquifer system underlying Box Butte County, Nebraska, has resulted in a steady decline of water levels. Consequently, a digital model of the aquifer system was constructed to evaluate various water-management alternatives. The hydraulic conductivity of...

The Muckleshoot Indian Tribe plans (1982) to build a fish hatchery in part of a 1.56-square-mile area in the Green River valley, Washington, and use groundwater to operate it. Groundwater data were collected in the area and used in a U.S. Geological Survey two-dimensional groundwater-flow model calibrated to simulate the...
The quality of ground water in the principal aquifers of northeastern-north central Washington
J.C. Ebbert
1984, Water-Resources Investigations Report 83-4102
In 1979 the quality of ground water in major aquifers in northeastern-north central Washington State was assessed in terms of inorganic-chemical, trace-metal, and fecal-coliform concentrations. For the Spokane Valley aquifer some organic-chemical data were also included. Results of this assessment indicate that the ground water in the region is generally...
