Ground-water resources in the Lompoc area, Santa Barbara County, California
G.A. Miller
1976, Open-File Report 76-183
Water supplies in the Lompoc plain are pumped from highly permeable gravel and sand, which make up the main water-bearing zone. The history of ground-water quality in the Lompoc area shows little change in the Lompoc upland and the Lompoc terrace, but an increase in the concentration of dissolved solids...
The Guatemalan earthquake of February 4, 1976, a preliminary report
A. F. Espinosa, editor(s)
1976, Professional Paper 1002
The Guatemalan earthquake of February 4, 1976, with a surface-wave magnitude of 7.5, was generated by left-lateral slippage on the Motagua fault and was felt over an area of at least 100,000 km2. This earthquake claimed more than 22,700 lives and injured more than 76,000 people. The preliminary estimate of...
Composition of selected rain samples collected at Menlo Park, California, 1971
Vance C. Kennedy, Gary W. Zellweger, Ronald J. Avanzino
1976, Open-File Report 76-852
Chemical analysis are tabulated for 104 rain samples that were collected at Menlo Park, California, during November and December 1971. Of the 13 constituents determined, chloride was the most prominent with a range from less than 0.1 to 15.0 mg/liter. (Woodard-USGS)...
Selected field data collected in 1975, northeastern Craig Quadrangle, southeastern Alaska
Henry C. Berg, A. Marianne Fujii
1976, Open-File Report 76-490
This report consists of a computer printout of geologic field data recorded by H.C. Berg from July 2 to July 20, 1975 in the part of the Craig (CR) 1:250,000-scale quadrangle northeast of Clarence Strait (figs. 1 and 2). It contains edited and revised observations on structure, lithology, mineralogy, metamorphism,...
Finite difference model for aquifer simulation in two dimensions with results of numerical experiments
Peter C. Trescott, George Francis Pinder, S. P. Larson
1976, Techniques of Water-Resources Investigations 07-C1
The model will simulate ground-water flow in an artesian aquifer, a water-table aquifer, or a combined artesian and water-table aquifer. The aquifer may be heterogeneous and anisotropic and have irregular boundaries. The source term in the flow equation may include well discharge, constant recharge, leakage from confining beds in which...
Research by the U.S. Geological Survey on organic materials in water
Robert Andrew Baker
1976, Circular 744
The U.S. Geological Survey has responsibility for investigating the Nation's water resources for source, availability, quantity, and quality. This paper describes the Geological Survey's research on organic substances in water and fluvial sediments. Results and ongoing studies are examined. Typical research includes: Separation, concentration, and chromatographic identification of volatile acids;...
The environment of South Florida; a summary report
B. F. McPherson, G.Y. Hendrix, Howard Klein, H.M. Tyus
1976, Professional Paper 1011
Man has altered the original south Florida ecosystem to a new three-part ecosystem which incorporates an agricultural component, an urban component, and a component of the original ecosystem that is largely unchanged but still has been affected by man. These components are interrelated through the flow of energy and material....
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Chandalar and Wiseman quadrangles, Alaska
Edward Huntington Cobb
1976, Open-File Report 76-340
These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Chandalar and Wiseman quadrangles in the southern Brooks Range, Alaska. All references to reports of the Geological Survey, to most reports of the U.S....
The United States Geological Survey in Alaska; organization and status of programs in 1976
Edward Huntington Cobb, editor(s)
1976, Circular 732
This report of the activities of the U.S. Geological Survey in Alaska is organized in four parts (1) services and responsibilities of the U.S. Geological Survey; (2) organization of the U.S. Geological Survey; 13) current U.S. Geological Survey activities; and (4) cooperative projects with Federal, State, and local agencies....
Reaeration-coefficient measurements of 10 small streams in Wisconsin using radioactive tracers : with a section on the energy-dissipation model
R. Stephen Grant
1976, Water-Resources Investigations Report 76-96
Reaeration-rate coefficients were measured for 10 small streams in Wisconsin using the radioactive-tracer method. The coefficients ranged from 2.06 to 55.2 per day (base e at 25 degrees Celsius). Stream discharges ranged from 0.3 to 37.0 cubic feet per second, most discharges being less than 10 cubic feet per second....
