Submarine geothermal resources
D.L. Williams
1976, Journal of Volcanology and Geothermal Research (1) 85-100
Approximately 20% of the earth's heat loss (or 2 ?? 1012 cal/s) is released through 1% of the earth's surface area and takes the form of hydrothermal discharge from young (Pleistocene or younger) rocks adjacent to active seafloor-spreading centers and submarine volcanic areas. This amount is roughly equivalent to man's...
Upland sandpiper nesting and management in North Dakota
L.M. Kirsch, K.F. Higgins
1976, Wildlife Society Bulletin (4) 16-20
Nests of 195 upland sandpipers (Bartramia longicauda) on the Missouri Coteau of North Dakota generally were well concealed by grassy vegetation which ranged from 15.4-30.8 cm in height. Nest densities ranged from 0.3 per 40.5 ha on annually tilled croplands to 6.8 per 40.5 ha on native grasslands during the...

Wildlife diseases: philosophical considerations
M. Friend
L.A. Page, editor(s)
1976, Book chapter, Wildlife diseases
Wildlife diseases are studied because of their adverse impact on human health, agriculture, or wildlife conservation. Viewpoints from these three major areas of concern are not always compatible, yet the ecological nature of disease makes it essential that each is recognized and understood. Within wildlife agencies, resistance or apathy toward...

Disharmony of the spheres: Recent trends in planetary surface nomenclature
R.J. Pike
1976, Icarus (27) 577-583
Inadvisable departures from tradition in naming newly mapped features on Mars, Mercury, and the Moon have been implemented and proposed since 1970. Functional need for place names also has become confused with cartographic convenience. Much of the resulting new nomenclature is neither unique, efficient, nor imaginative. The longstanding classical orientation...
Chemical and physical data for the Flaming Gorge Reservation area, Utah and Wyoming, 1973-75
E.L. Bolke
1976, Utah Basic-Data Release 27
This report presents the basic data that were collected by the U.S. Geological Survey during a study of the chemical quality of water in Flaming Gorge Reservoir. An interpretive report will follow. The basic data were collected from the reservoir during the period August 1973 to October 1975. The reservoir...
Ecology of mangroves in the Jewfish Chain, Exuma, Bahamas
L. V. Wilcox, Thomas G. Yocom, A. M. Forbes
1976, Conference Paper, Proceedings of the International Symposium on biology and management of mangroves
The structure and function of mangrove communities in the Jewfish Chain, Exumas, Bahamas, were investigated for 3-1/2 years. Mangrove vegetation in the Jewfish Chain is similar to that in all the Caribbean-Florida area; Rhizophora mangle L. dominates and is interspersed with Avicennia germinans (L.) Lamk. and Laguncularia racemosa (L.) Gaertn. There is no apparent zonation of...
Selected hydrologic data, Uinta Basin area, Utah and Colorado
J. W. Hood, J. C. Mundorff, Don Price
1976, Utah Basic-Data Release 26
The Uinta Basin area in northeastern Utah and northwestern Colorado covers an area of slightly more than 10,000 mi2 (25,900 km2). More than 95 percent of the basin is in Utah, thus most of the data in this report apply to Utah. Most of the water wells are concentrated in...

Atomic absorption spectrometric determination of copper, zinc, and lead in geological materials
R. F. Sanzolone, T. T. Chao
1976, Analytica Chimica Acta (86) 163-168
An atomic absorption spectrometric method is described for the determination of copper, zinc, and lead in geological materials. The sample is digested with HF—HCl—H2O2; the final solution for analysis is in 10 % (v/v) HCl. Copper and zinc are determined directly by aspirating the solution into an air—acetylene flame. A...
Progress in remote sensing (1972-1976)
W. A. Fischer, W. R. Hemphill, Allan Kover
1976, Photogrammetria (32) 33-72
This report concerns the progress in remote sensing during the period 1972–1976. Remote sensing has been variously defined but is basically the art or science of telling something about an object without touching it. During the past four years, the major research thrusts have been in three areas: (1) computer-assisted enhancement and...
The dissolution of calcite in CO2-saturated solutions at 25°C and 1 atmosphere total pressure
Niel Plummer, T.M.L. Wigley
1976, Geochimica et Cosmochimica Acta (40) 191-202
The dissolution of Iceland spar in CO2-saturated solutions at 25°C and 1 atm total pressure has been followed by measurement of pH as a function of time. Surface concentrations of reactant and product species have been calculated from bulk fluid data using mass transport theory and a model that accounts...
An outbreak of erysipelas in eared grebes (Podiceps nigricollis)
Wayne I. Jensen, Sally E. Cotter
1976, Journal of Wildlife Diseases (12) 583-586
An outbreak of erysipelas killed an estimated 5,000 aquatic birds on Great Salt Lake (Utah) in late November, 1975. Although several thousand ducks and gulls were using the lake, at least 99 percent of the victims were eared grebes. A hypothetical explanation for the selective mortality is offered....
Distribution of small channels on the Martian surface
D. Pieri
1976, Icarus (27) 25-50
The distribution of small channels on Mars has been mapped from Mariner 9 images, at the 1:5 000 000 scale, by the author. The small channels referred to here are small valleys ranging in width from the resolution limit of the Mariner 9 wide-angle images (???1 km) to about 10...
Q-mode factor analysis of compositional data
A.T. Miesch
1976, Computers & Geosciences (1) 147-159
An extended form of the method of Q-mode factor analysis may be used if the rows of the data matrix sum to a constant. The constant row-sum provides a means for scaling the factor model to conform to the units of the original data in such forms as proportions, percentages,...
The national coal-resources data system of the U.S. geological survey
M.D. Carter
1976, Computers & Geosciences (2) 331-340
The National Coal Resources Data System (NCRDS) was designed by the U.S. Geological Survey (USGS) to meet the increasing demands for rapid retrieval of information on coal location, quantity, quality, and accessibility. An interactive conversational query system devised by the USGS retrieves information from the data bank through a standard...
Capturing and marking howler monkeys for field behavioral studies
N.J. Scott Jr., A.F. Scott, L.A. Malmgren
1976, Primates (17) 527-533
Methods for capturing and marking howler monkeys for ecological studies are discussed. Systems for capturing and handling animals are compared. A dart with liquid Sernylan for capture and Sernylan or Ketamine as a holding drug was preferred to darts using powdered succinylcholine chloride (SCC) and ether. The effectiveness of both...

M. V. Johnson, R. J. Omang
1976, Open-File Report 75-650
This report provides methods for estimating flood characteristics at most natural flow sites on rural streams in Montana. It also contains significant flood data and related information for many gaged sites on Montana streams. Frequency curves are provided for 442 gaged sites as defined by log-Pearson Type III analysis. To...
The Anderson Reservoir seismic gap - Induced aseismicity?
C. G. Bufe
1976, Engineering Geology (10) 255-262
A persistent 10-km seismicity gap along the Calaveras fault appears to be related to the presence of the Leroy Anderson Reservoir in the Calaveras-Silver Creek fault zones southeast of San Jose, California. A magnitude-4.7 earthquake occurred at a depth of 5 km in the centre of the gap on October...
Seismicity and faulting attributable to fluid extraction
R. F. Yerkes, R. O. Castle
1976, Engineering Geology (10) 151-167
The association between fluid injection and seismicity has been well documented and widely publicized. Less well known, but probably equally widespread are faulting and shallow seismicity attributable solely to fluid extraction, particularly in association with petroleum production. Two unequivocable examples of seismicity and faulting associated with fluid extraction in the...
