Publications on fish parasites and diseases, 330 B.C.-A.D. 1923
E.A. McGregor
1963, Report
These references were collected in 1924, but until now this collection has been available only in manuscript:fbrm. Because of the current increased interest in this field, this bibliography is being issued to make it more generally accessible. They include the earliest known references to fish parasites (330 B. C.) as...
Food of the bloater, Coregonus hoyi, in Lake Michigan
LaRue Wells, Alfred M. Beeton
1963, Transactions of the American Fisheries Society (92) 245-255
Stomachs were examined from 1,469 Lake Michigan bloaters, Coregonus [Leucichthys] hoyi, greater than 7 inches long which contained identifiable food. An additional 461 ciscoes less than 7 inches long were incorporated into the study; these latter fish were not positively identified, but most of them undoubtedly were bloaters. The specimens...
Applications of geohydrologic concepts in geology
G. B. Maxey, J. E. Hackett
1963, Journal of Hydrology (1) 35-45
Subsurface water, an active agent in many geologic proceses, must be considered in interpreting geologic phenomena. Principles of the occurrence, distribution, and movement of subsurface waters are well established and readily applicable. In many interpretations in geologic literature, geohydrologic principles have been employed realistically, but in many others these principles...
New chemical determinations of zinc in basalts, and rocks of similar composition
L. F. Rader, W. C. Swadley, C. Huffman Jr., H. H. Lipp
1963, Geochimica et Cosmochimica Acta (27) 695-714
New determinations of zinc in 124 basalts by the chemical method described (Huff-Manet al. 1963) are reported. Average zinc values, in per cent, for basalts from diverse regions are as follows: Idaho, 28 samples, 0.013; Hawaii, 33 samples, 0.010; Connecticut, 27 samples, 0.0090; Oregon, 17 samples, 0.0081; California, 8 samples,...
Floods in Wyoming, magnitude and frequency
J. R. Carter, A. Rice Green
1963, Circular 478
This report contains the results of four separate flood-frequency analyses designated A, B, C, and D. Analysis A is for the portion of Wyoming east of the Continental Divide. Analysis B applies to the portion of Wyoming in Part 9, as designated in streamflow reports entitled "Surface Water Supply of...
Unmineralized fossil bacteria
W. H. Bradley
1963, Science (141) 919-921
Unmineralized bacterial cells, mostly Micrococcus sp., but including also Streptococcus sp. and Actinomyces sp., were found in enormous numbers in lake beds of the Newark Canyon Formation of Early Cretaceous age, Eureka County, Nevada. The micrococci are black, and have an average diameter about 0.5 µ. Similar black micrococci (0.4...
Some climatic indicators in the period A.D. 1200-1400 in New Mexico
Luna Bergere Leopold, Estella B. Leopold, F. Wendorf
1963, Conference Paper
Three centuries before Columbus landed in America, the alluvial valleys of the south-western United States teemed with activity. The indigenous peoples had been building for 300 years a culture centred around community life based on flood-water farming and on hunting. A large number of pueblos had developed on sites earlier...
Simple measurements of morphological changes in river channels and hillslopes
J.P. Miller, Luna Bergere Leopold
1963, Conference Paper
One of the principal types of observational evidence on climatic changes in the recent geologic past is in river position and elevation. It is well known that river channels, particularly those flowing through alluvium or on relatively soft bedrock, tend to develop flood plains by lateral migration of the channel....
Association and determinacy in geomorphology
Luna Bergere Leopold, Walter Basil Langbein
Claude C. Albritton Jr., editor(s)
1963, Book chapter, The fabric of geology
You find a rock. It looks like an ordinary piece of flint, broken and rough. On a part of it is a patina whose soft grey color contrasts with the shiny brownish surfaces of conchoidal fracture. You could have found this rock in nearly any kind of an environment almost...
Conversations on ecology IV
Luna Bergere Leopold
1963, The Garden Journal: Journal of the New York Botanical Garden (13) 141-142
The conversations on ecology have mentioned the pesticide problem, and in such discussion it is easy to lose sight of the basic philosophic view which is an undercurrent in Miss Carson's book. I should like to expand on that philosophic premise and examine some of its implications for planning vegetation...
A primer on ground water
Helene L. Baldwin, C. L. McGuinness
1963, Report
Most of us don't have to look for water. We grew up either in big cities where there was a public water supply, or in small towns or on farms where the water came from wells. But there are some people to whom finding a new supply of water is...
Late Pleistocene glacial drainage in the Devils Lake Region, North Dakota
Saul Aronow
1963, GSA Bulletin (74) 859-874
The Devils Lake region of northeastern North Dakota is covered with glacial drift deposited by the Leeds lobe of the Mankato Substage of the Wisconsin Stage of the Pleistocene and is underlain by Pierre Shale of Cretaceous age. Associated with the Sheyenne River, which flows through the southern part of...
Water resources investigations: A section in Thirty-third biennial report of the State Engineer to the governor of Utah: 1960-1962
U.S. Geological Survey
1962, Utah State Engineer Biennial Report 33
The Geological Survey is authorized by Congress to cooperate with the States and other local governmental units in water-resources investigations on a 50-50 financial basis. Principal cooperation for Utah is through the office of the Utah State Engineer. Other State offices, such as the State Road Commission, Water and Power...
Water production from oil wells of the Uinta Basin, Uintah and Duchesne Counties, Utah
Harry D. Goode, Richard D. Feltis
1962, Utah Geological and Mineralogical Survey Water-Resources Bulletin 1
Water production from individual oil wells in the Uinta Basin ranges from 0 to 2,920,000 barrels (about 380 acre-feet) per year. The total dissolved solids in the water ranges from 500 to 26,000 ppm (parts per million); thus some of the water is classified as fresh and can be used,...
An interim report on Sacramento River Chinook disease: A virus-like disease of Chinook salmon
T. J. Parisot, J. Pelnar
1962, Progressive Fish-Culturist (24) 51-55
An annually recurring disease among chinook salmмом (Oncorhynchus tahawytscha) FINGERLINGs at the National Fish Hatchery at Coleman, California, was reported by Ross, Pelnar, and Rucker (1960). They presented results of experimental investigation of the disease which established that the etiologic agent was filterable, highly virulent, and resistant to antibiotics and some of the...
Molar volumes and densities of minerals
Richard A. Robie, Philip M. Bethke
1962, Trace Elements Investigations 822
These tables present critically chosen "best values" for the density and molar volume of selected mineral compounds. No attempt was made to be all-inclusive; rather we have tried to present data for chemically and physically well-defined phases for which the molar volume and/or density was knovvn to the order of...
