Hydromagnetic constraints on deep zonal flows in the giant planets
Randolph L. Kirk, David J. Stevenson
1987, Astrophysical Journal (316) 836-846
The observed zonal flows of the giant planets will, if they penetrate below the visible atmosphere, interact significantly with the planetary magnetic field outside the metallized core. The appropriate measure of this interaction is the Chandrasekhar number Q = H^2 /4πρνα^2 λ (H = radial component of the magnetic field,...

Post-fire demography of resprout and seedling establishment by Adenostoma fasciculatum in the California chaparral
P.W. Rundel, G.A. Baker, D.J. Parsons, T.J. Stohlgren
1987, Book chapter, Functional Analysis in Mediterranean Ecosystems
Adenostoma fasciculatum (chamise) forms the dominant element of chaparral ecosystems in California. This evergreen, ericoid-leaved shrub occurs as a codominant in mixed chaparral or an overwhelming dominant in chamise chaparral, being present in over 70% of the chaparral stands in the state (Hanes 1971). No other chaparral shrub approaches A....

Monitoring active volcanoes
Robert I. Tilling
1987, Report
One of the most spectacular, awesomely beautiful, and at times destructive displays of natural energy is an erupting volcano, belching fume and ash thousands of meters into the atmosphere and pouring out red-hot molten lava in fountains and streams. Countless eruptions in the geologic past have produced volcanic rocks that...
Instream water use in the United States: water laws and methods for determining flow requirements
Berton L. Lamb, Harvey R. Doerksen
1987, Report, National Water Summary 1987
Water use generally is divided into two primary classes - offstream use and instream use. In offstream use, sometimes called out-of-stream or diversionary use, water is withdrawn (diverted) from a stream or aquifer and transported to the place of use. Examples are irrigated agriculture, municipal water supply, and industrial use....

Disease control operations
Milton Friend, J. Christian Franson
1987, Report, Field guide to wildlife diseases: volume 1. General field procedures and diseases of migratory birds
Individual disease outbreaks have killed many thousands of animals on numerous occasions. Tens of thousands of migratory birds have died in single die-offs with as many as 1,000 birds succumbing in 1 day. In mammals, individual disease outbreaks have killed hundreds to thousands of animals with, for example, hemorrhagic disease...
Prospects for Yellowstone grizzly bears
R.R. Knight, L.L. Eberhardt
1987, Bears: Their Biology and Management (7) 45-50
Recent analyses of data on the grizzly bear (Ursus arctos horribilis) population of Yellowstone National Park and its environs suggest the likelihood of a continuing decline in numbers if losses of fully adult females are not reduced. The size of the population is not known, and a simple projection model...
Size and growth patterns of the Yellowstone grizzly bear
Bonnie M. Blanchard
1987, Book, Bears, their biology and management : papers and proceedings of the International Conference on Bear Research and Management
Weights and/or measurements of 151 grizzly bears (Ursus arctos) captured 261 times were recorded from 1975 to 1985. Males were consistently heavier than females within all age classes beginning at age 2. Mean weight for 65 captive males (5+ years old) was 192 kg and 135 kg for...

Specimen collection and preservation
J. Christian Franson
1987, Report, Field guide to wildlife diseases: volume 1. General field procedures and diseases of migratory birds
Specimens, as discussed in this handbook, have but a single purpose--to provide information leading to the diagnosis of a cause of disease or death. A specimen may be an intact carcass, various tissues removed from carcasses, or parasites. In any event, the specimen should be as fresh and undamaged as...
Recording and submitting specimen history data
J. Christian Franson
1987, Report, Field guide to wildlife diseases: volume 1. General field procedures and diseases of migratory birds
Webster defines history as "a chronological record of significant events." In wildlife disease investigations, determining the history or background of a problem is the first significant step in establishing a diagnosis. You can greatly assist the diagnostic process by providing a thorough history with specimens yo submit. This information is...

At the end of 1980, seven complete cores were recovered from a 30-m (100-ft) interval in the Raton Formation at York Canyon, New Mexico. The interval cored spans the palynologically defined Cretaceous-Tertiary...
Lead isotopic fingerprinting of tectono-stratigraphic terranes, east-central Alaska
John N. Aleinikoff, Cynthia Dusel-Bacon, Helen Laura Foster, Warren J. Nokleberg
1987, Canadian Journal of Earth Sciences (24) 2089-2098
Common lead isotopic compositions have been determined on feldspars from meta-igneous rocks from nine tectono-stratigraphic terranes or subterranes in east-central Alaska. Most of the terranes have distinct and well-defined signatures in terms of isotopic composition; thus, most can be distinguished on conventional...

Snowpack ion accumulation and loss in a basin draining to Lake Superior
Robert Stottlemyer
1987, Canadian Journal of Fisheries and Aquatic Sciences (44) 1812-1819
The objective of this study was to relate winter precipitation ionic inputs, snowpack retention, and change in first-order stream chemistry with spring snowpack melt. During winter 1982–83, measurement of precipitation inputs, snowpack concentration and loading, and streamwater concentration and discharge of Ca2+, K+, H+, NO3−, and SO42− from a 176-ha...
Passive margins: U.S. Geological Survey Line 19 across the Georges Bank basin

Georges Bank is a shallow part of the Atlantic continental shelf southeast of New England (Emery and Uchupi, 1972, 1984). This bank, however, is merely the upper surface of several sedimentary basins overlying a block-faulted basement of igneous and metamorphic crystalline rock. Sedimentary rock forms a seaward-thickening cover that has...
