Aqua de Ney, California, a spring of unique chemical character
J. H. Feth, S. M. Rogers, C. E. Roberson
1961, Geochimica et Cosmochimica Acta (22) 75-86
The chemistry of water of Aqua de Ney, a cold spring of unusual character located in Siskiyou County, Calif., has been re-examined as part of a study of the relation of water chemistry to rock environment. The water has a pH of 11·6 and a silica content of 4000 parts...
Palæomagnetic evidence relevant to a change in the earth's radius
Allan Cox, Richard R. Doell
1961, Nature (189) 45-47
INTEREST in the hypothesis that the Earth's radius has increased during geological history has been renewed in recent years because of several sets of independent observations and interpretations. From studies of the deformation of mountain ranges and the distribution of faults and oceans, Carey1 proposes an increase in the Earth's area...
Palæomagnetism of Hawaiian lava flows
Richard R. Doell, Allan Cox
1961, Nature (192) 645-646
PALÆOMAGNETIC investigations of volcanic rocks extruded in various parts of the world during the past several million years have generally revealed a younger sequence of lava flows magnetized nearly parallel to the field of a theoretical geocentric axial dipole, underlain by a sequence of older flows with exactly the opposite...
Use of 3-trifluormethyl-4-nitrophenol as a selective sea lamprey larvicide
Vernon C. Applegate, John H. Howell, James W. Moffett, B. G. H. Johnson, Manning A. Smith
1961, Technical Report 1
The recent discovery of a group of chemical compounds that are significantly more toxic to sea lampreys than to other aquatic organisms offers promise of an early and effective control of this pest. The sea lamprey has all but destroyed the lake trout populations of Lakes Huron and Michigan. In...
Mineralogy and geochemistry of vanadium in the Colorado Plateau
A. D. Weeks
1961, Journal of the Less-Common Metals (3) 443-450
The chief domestic source of vanadium is uraniferous sandstone in the Colorado Plateau. Vanadium is 3-, 4-, or 5-valent in nature and, as oxides or combined with other elements, it forms more than 40 minerals in the Plateau ores. These ores have been studied with regard to the relative amounts...
Radio-tracer techniques for the study of flow in saturated porous materials
H.E. Skibitzke, H. T. Chapman, G.M. Robinson, Richard A. McCullough
1961, International Journal of Applied Radiation and Isotopes (10) 38-42
An experiment was conducted by the U.S. Geological Survey to determine the feasibility of using a radioactive substance as a tracer in the study of microscopic flow in a saturated porous solid. A radioactive tracer was chosen in preference to dye or other chemical in order to eliminate effects of...
Records and water-level measurements of selected wells and chemical analysis of ground water, East Shore area, Davis, Weber, and Box Elder Counties
Ralph E. Smith
1961, Utah Basic-Data Report 1
This report is intended to serve two purposes: (1) to make available to the public basic ground-water data useful in planning and studying development of water resources and (2) to supplement an interpretive report that will be published later.Records were collected during the period 1935-61 by the U.S. Geological Survey...
Geology and ground-water resources of Clayton County, Iowa
W. L. Steinhilber, O. J. Van Eck, A.J. Feulner
1961, Water Supply Bulletin 7
Clayton County includes 784 square miles in northeastern Iowa and in 1960 had a population of 21, 962.  For the most part, the county is a dissected upland that is drained mainly by the southeastward flowing Turkey River and its principal tributary, the Volga River.  The Turkey River empties into...
Philosophy for water development
Luna Bergere Leopold, E. L. Hendricks
1961, Conference Paper
There is probably no one in this room who has not had an experience analogous to the one I here describe. You sat at the dinner table next to a nice lady who impressed you with her breadth of interest in community affairs. She said to you "Oh, you work...
Surface water records of Colorado, 1961
Water Resources Division U.S. Geological Survey
1961, Water Data Report CO-61-1
The surface-water records for the 1961 water year for gaging stations and miscellaneous sites within the State of Colorado are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed by the Water Resources...
Detrital-appearing uraninite grains in the shinarump member of the chinle formation in northern Arizona
R.G. Petersen
1960, Economic Geology (55) 138-149
A sample of uranium-bearing conglomerate from the Shinarump member of the Chinle formation in northern Arizona was disaggregated in an ultrasonic separator. The sample, weighing 187 grams, contained about 60 grains of uraninite (from 0.1 to 1 mm diameter) which have the sphericity and polish suggestive of detrital grains. The detrital-appearing grains are associated with abundant...
Ground-water areas and well logs, central Sevier Valley, Utah
Richard A. Young
1960, Utah State Engineer Information Bulletin 3
Between September 1959 and June 1960 the United States Geological Survey and the Utah State Engineer, with financial assistance from Garfield, Millard, Piute, Sanpete, and Sevier Counties and from local water-users’ associations, cooperated in an investigation to determine the structural framework of the central Sevier Valley and to evaluate the...
Ground-water investigations in Utah in 1960 and ground-water reports published by the U.S. Geological Survey or the Utah State Engineer prior to 1960
Harry D. Goode
1960, Utah State Engineer Information Bulletin 4
Listed below and shown on the map are projects in the ground-water program being conducted cooperatively by the U.S. Geological Survey and the Utah State Engineer. Project UT-5 is conducted from a field office in Cedar City, project UT-17 from a field office in Richfield, project UT-26 from a field...
A statistical analysis of the distribution of a larval nematode (Anisakis sp.) in the musculature of chum salmon (Oncorhynchus keta - Walbaum)
A.J. Novotny
1960, Experimental Parasitology (10) 60-67
The pepsin-HCl digestion technique is probably the best method of isolating Anisakislarvae from the musculature of chum salmon. Some losses can be expected due to breakage of the resistant cuticle of Anisakis, and can be estimated to be about 6% when counting the parasites with the unaided eye. Comparisons of Anisakis infections of the dorsal...
A bacterial disease of yellow perch (Peres flavescens)
A. J. Ross, P.R. Nordstrom, J.E. Bailey, J.H. Heaton
1960, Transactions of the American Fisheries Society (89) 310-312
On May 26, 1959, two of the authors' investigated a fish kill at Dailey Lake, Park County, Montana. They observed about a half-dozen live, weakly swimming yellow perch (Perca flavescens), in addition to thousand of dead perch along the shoreline. It was learned from local residents that mortalities had begun...
Ovarian fluid: Its role in fertilization
R.R. Rucker, J.F. Conrad, C.W. Dick
1960, Progressive Fish-Culturist (22) 77-78
FISH-CULTURISTs, in general, do not agree as to the time of actual fertilization of artificially spawned salmonid eggs. Some fish-culturists believe that the eggs are fertilized in the milt before water is added, while others are equally certain that fertilization is not achieved until after water is added. This difference...
