Genetic differences in growth and survival of juvenile hatchery and wild steelhead trout, Salmo gairdneri
R.R. Reisenbichler, J.D. McIntyre
1977, Journal of the Fisheries Research Board of Canada (34) 123-128
Relative growth and survival of offspring from matings of hatchery and wild Deschutes River (Oregon) summer steelhead trout, Salmo gairdneri, were measured to determine if hatchery fish differ genetically from wild fish in traits that can affect the stock–recruitment relationship of wild populations. Sections of four natural streams and a...
Use of water in Arkansas, 1975
Henry N. Halberg
1977, Water Resources Summary 9
This report contains statistical information relating to water use in Arkansas. The principle categories of water use, other than hydroelectric energy generation, are public supply, self-supplied industrial use, rural domestic and livestock use, irrigation, fish and minnow farming, water for wild life impoundments, and thermoelectric-energy generation. About half...
Water resources of the Weiser River basin, west-central Idaho
H.W. Young, W. A. Harenberg, Harold R. Seitz
1977, Water Information Bulletin 44
The study area comprises about 1,600 square miles (4,100 square kilometers) in west-central Idaho and includes the entire Weiser River basin and small areas both west and south of Weiser outside the basin. The basin is sparsely populated and the economy is chiefly agricultural....
Planimetric Martian triangulations
D.W.G. Arthur, D.K. McMacken
1977, Photogrammetric Engineering and Remote Sensing (43) 701-707
Narrow-angle photographs, which have severe drawbacks for stereophotogrammetry, have advantages for simple plane triangulations. Rectified narrow-angle pictures corrected for map projection effects can be combined in the map plane in relatively accurate planimetric triangulations. Provided the strict precepts of least squares are not followed, these triangulations can incorporate considerable overdetermination...
Preliminary bedrock geologic map of part of the northern disturbed belt, Lewis and Clark, Teton, Pondera, Glacier, Flathead, and Powell Counties, Montana
Melville R. Mudge, Robert L. Earhart, Dudley D. Rice
E.L. Heisey, editor(s)
1977, Rocky Mountain thrust belt geology and resources (29th Annual Field Conference Guidebook) 471-478
The geologic map covers the Sawtooth and Lewis and Clark Ranges and part of the Flathead Range. It includes most of the disturbed belt in northwestern Moutana except the area east of the northern Rocky Mountains and the norhtern and southern parts of the belt. Most data are from an...
Combined use of digital aquifer models and field base-flow data to identify recharge-leakage areas of artesian aquifers
Richard H. Johnston, P. Patrick Leahy
1977, Journal of Research of the U.S. Geological Survey (5) 491-496
As a result of continuous pumping since the 1890's, a regional cone of depression encompassing 363 km2 has developed within the artesian Miocene Cheswold aquifer at Dover, Del. The aquifer is not being recharged significantly by leakage near the center of the cone, nor is major recharge induced in the...
High-resolution gamma-ray spectrometry in uranium exploration
Robert M. Moxham, Allan B. Tanner
1977, Journal of Research of the U.S. Geological Survey (5) 783-785
Sedimentary-type uranium deposits accumulate at favorable sites along a migration path which may be kilometers in length. Their source is a large volume of rock from which the uranium has been leached. The geochemical mobilities and half lives of uranium and its daughter products vary widely so that they are...
Black monazite from Taiwan
J.J. Matzko, W.C. Overstreet
1977, Proceedings of the Geological Society of China (20) 16-35
Two forms of detrital monazite are known in offshore bars in southwestern Taiwan: a yellow-green to colorless form and an unusual but abundant pelletlike form, generally black but also colored gray or brown. These black pellets, which are about 160 by 200 microns in size, are composed of fine-grained monazite...
Hydrologic evaluation of Ashley Valley, northern Uinta basin area, Utah
James W. Hood
1977, Technical Publication 54
The water resources of the northern Uinta Basin, Utah and Colorado, were studied during 1971-74. Ashley Valley was evaluated in slightly greater detail than the general area, in order to assess the general relation of ground- and surface-water supplies. In Ashley Valley , the principal source of both irrigation supply and ground-water...
Application of linear statistical models of earthquake magnitude versus fault length in estimating maximum expectable earthquakes
Robert K. Mark
1977, Geology (5) 464-466
Correlation or linear regression estimates of earthquake magnitude from data on historical magnitude and length of surface rupture should be based upon the correct regression. For example, the regression of magnitude on the logarithm of the length of surface rupture L can be used to estimate magnitude, but the regression of log L on...
