Marine magnetic gradiometer: A tool for the seismic interpreter
Richard J. Wold, Alan K. Cooper
1989, Geophysics (8) 22-27
The marine magnetometer has been used since the early '50s as an ancillary tool on vessels conducting regional and local seismic surveys. Emphasis on marine magnetic data by academia has led to major discoveries about the structure of the earth's crust, such as the association of shallow, crustal magnetic anomalies...
Accuracy of acoustic velocity metering systems for measurement of low velocity in open channels
Antonius Laenen, R. E. Curtis Jr.
1989, Water-Resources Investigations Report 89-4090
Acoustic velocity meter (AVM) accuracy depends on equipment limitations, the accuracy of acoustic-path length and angle determination, and the stability of the mean velocity to acoustic-path velocity relation. Equipment limitations depend on path length and angle, transducer frequency, timing oscillator frequency, and signal-detection scheme. Typically, the velocity error from this...
Volcanic hazards at Mount Shasta, California
Dwight R. Crandell, Donald R. Nichols
1989, Report
The eruptions of Mount St. Helens, Washington, in 1980 served as a reminder that long-dormant volcanoes can come to life again. Those eruptions, and their effects on people and property, also showed the value of having information about volcanic hazards well in advance of possible volcanic activity. This pamphlet about...

The Macon Complex; An ancient accretionary complex in the southern Appalachians
Michael W. Higgins, Ralph Crawford, R. L. Atkins, Thomas J. Crawford
1989, Book chapter, Mélanges Olistostromes of the U.S. Appalachians
The Macon Complex, which extends from eastern Alabama to northern North Carolina, is a late Precambrian–Middle Cambrian accretionary complex comparable in size to the Franciscan Complex of California and Oregon. Much of the complex is tectonic, sedimentary, and metamorphic chaos, properly termed mélange, where well-rounded to angular fragments, blocks, and slabs of...
Acid rain publications by the U.S. Fish and Wildlife Service, 1979-1989
Rita F. Villella
1989, Biological Report 80(40.28)
Pollution of aquatic and terrestrial ecosystems has been a concern to society since the burning of fossil fuels began in the industrial revolution. In the past decade or so, this concern has been heightened by evidence that chemical transformation in the atmosphere of combustion by-products and subsequent long-range transport can...

Mélanges and olistostromes in the Appalachians of the United States and mainland Canada; An assessment
Nicholas Rast, J. Wright Horton, Jr.
1989, Book chapter, Mélanges Olistostromes of the U.S. Appalachians
There is no completely accepted definition of a mélange, and the papers in this volume reflect this fact. In our regional assessment, the term mélange is principally used for a technically fragmented and mixed body of rock. A different term, olistostrome, is used for a chaotic and mixed rock body...

1989, Report
There is a need for accurate and standard geographic names usage in all levels of government, industry, commerce, communications, education, and research. There is also a growing number of organizations in North America that are, fully or partly, involved in the scholarly study of geographic names. This report is a...
Comprehensive technologies and decision-making: Reflections on the instream flow incremental methodology
Berton Lee Lamb
1989, Fisheries (14) 12-16
The controversy surrounding the Instream Flow Incremental Methodology is briefly discussed. A 1968 article by James Schlesinger on the likely success of systems analysis in aiding decision-makers is used to illustrate some pitfalls involving comprehensive technologies. The lessons of systems analysis are drawn together with the literature on instream flow...

Suspected fusariomycotoxicosis in sandhill cranes (Grus canadensis): clinical and pathological findings.

1989, Avian Diseases (33) 451-457
In 1985 and 1986, large-scale natural die-offs of sandhill cranes in Texas were attributed to fusariomycotoxicosis. These birds demonstrated a progressive loss of motor control to the neck, wings, and legs. Based on necropsy and/or histopathology of 31 cranes, the most common lesions involved skeletal muscle and included hemorrhages, granulomatous...
