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...
Quantitation of microorganic compounds in waters of the Great Lakes by adsorption on activated carbon
Stacy L. Daniels, Lloyd L. Kempe, E. S. Graham, Alfred M. Beeton
1963, Conference Paper, Proceedings of the 6th Conference on Great Lakes Research
Microorganic compounds in waters of Lakes Michigan and Huron have been sampled by adsorption on activated carbon in filters installed aboard the M/V Cisco and at the Hammond Bay Laboratory of the U.S. Bureau of Commercial Fisheries. The organic compounds were eluted from the carbon according to techniques developed at the U.S....
A plane-type soil sampler
Paul J. Frey
1963, Progressive Fish-Culturist (25) 46-49
While studying the effects of pesticides on fish and their environment for the Bureau of Sport Fisheries and Wildlife, I have developed a soil sampler that will collect a thin uniform layer of sediment from pond and stream bottoms. As it is becoming increasingly important to analyze the residual deposits...
Diffusion of herbicides through plastic film
W.R. Bridges, Herman O. Sanders
1963, Progressive Fish-Culturist (25) 213-214
Plastic film have been used by fishery workers as barriers to subdivide experimental ponds in order to assess the value of some chemical treatment, and as test vessels to contain dilute solutions or suspensions of toxic chemicals in experiments conducted to establish tolerance levels of these chemicals for fish....

Aromatic fluorine compounds. XI. Replacement of chlorine by fluorine in halopyridines
G. C. Finger, L. D. Starr, D. R. Dickerson, H. S. Gutowsky, J. Hamer
1963, Journal of Organic Chemistry (28) 1666-1668
The α-halogenated pyridines react with potassium fluoride in various solvents to give replacement of the α-halogen by fluorine. A 50% yield of 2-fluoropyridine was obtained from 2-chloropyridine by heating with potassium fluoride in dimethyl sulfone or tetramethylene sulfone for twenty-one days; 2-bromopyridine gave a similar yield with a heating period...
Deuterium in Iceland waters
I. Friedman, T. Sigurgeirsson, O. Gardarsson
1963, Geochimica et Cosmochimica Acta (27) 553-561
From the deuterium analysis of 159 samples of water collected in Iceland from hot-water boreholes, cold and hot springs, rivers and rain, the geographical distribution of deuterium in surface waters is plotted. On the basis of the deuterium analysis, the water from boreholes near Reykjavik does not originate from local...
The precipitation of aluminum, iron and manganese at the junction of Deer Creek with the Snake River in Summit County, Colorado
P. K. Theobald Jr., H. W. Lakin, D. B. Hawkins
1963, Geochimica et Cosmochimica Acta (27) 121-132
The oxidation of disseminated pyrite in relatively acid schists and gneisses of the Snake River drainage basin provides abundant iron sulfate and sulfuric acid to ground and surface water. This acid water dissolves large quantities of many elements, particularly aluminum and surprisingly large quantities of elements, such as magnesium and...
Implications of the minor element content of some major streams of the world
W. H. Durum, J. Haffty
1963, Geochimica et Cosmochimica Acta (27) 1-11
Of 15 or more minor elements in the world's principal river waters only aluminum, iron, manganese, barium and strontium range much over 100 μgl">100 μgl. (parts per billion). Most minor elements range at or below 100 μg1">100 μg1. and have...
Study of multicomponent mixtures in solution with a vertical-axis transmission-type filter-fluorometer
M. H. Fletcher
1963, Analytical Chemistry (35) 278-288
Fluorescence intensity, sensitivity, and the effect of diverse ions are discussed in relation to chemical equilibrium and the general equation for fluorescence. High sensitivity is the common denominator in eliminating or reducing all types of interference and the general equation is the key for quickly selecting conditions that give maximum...
Antiferromagnetism of UO2⋅2H2O
T. Pankey, F. E. Senftle, F. Cuttitta
1963, Journal of Chemical Physics (39) 1702-1706
Magnetic susceptibility measurements have been made on UO2·xH2O for x=1.78 to x=2.13, and from 77° to 375°K. As the value of x decreased the susceptibility increased. Both these data and structural arguments imply that the formula of this compound is U(OH)4 rather than the dihydrate form. Based on this concept the data have been corrected...
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...
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,...
Spectrophotometric determination of micro quantities of zinc in rocks
C. Huffman Jr., H. H. Lipp, L. F. Rader
1963, Geochimica et Cosmochimica Acta (27) 209-215
A chemical method is presented for the determination of microgram amounts of zinc in rocks. Zinc is absorbed on anion-exchange resin from 1.2 M hydrochloric acid and eluted with 0.01 M hydrochloric acid. A diethyldithiocarbamate separation removes traces of interfering elements from the eluate. The zinc-diethyldithiocarbamate complex is extracted into...
Releasing-addition method for the flame-photometric determination of calcium in thermal waters
J.J. Rowe
1963, Geochimica et Cosmochimica Acta (27) 915-923
Study of the interferences of silica and sulfate in the flame-photometric determination of calcium in thermal waters has led to the development of a method requiring no prior chemical separations. The interference effects of silica, sulfate, potassium, sodium, aluminum, and phosphate are overcome by an addition technique coupled with the...
The use of alkalinity and conductivity measurements to estimate concentrations of 3-trifluormethyl-4-nitrophenol required for treating lamprey streams
Richard K. Kanayama
1963, Technical Report 7
A method has been devised to estimate the minimum concentration of TFM that will kill sea lampreys and the maximum that will not kill fish. It is based on the relation of these concentrations to the alkalinity and the conductivity of various waters. Pretreatment bioassays will continue to...
Population analyses, variation and behavior of Anguispira alternata alternata
Charles L. Douglas
1963, Transactions of the Kansas Academy of Science (66) 186-194
Anguispira alternata alternata is one of the more common terrestrial snails in the United States. Gregarious by nature, these snails can be collected in large numbers from wooded flood-plains and moist upland wooded areas. "The range is eastern Canada and the United States, from Nova Scotia to Lake of...
Limnological survey of Lake Erie 1959 and 1960
Alfred M. Beeton
1963, Technical Report 6
Federal, provincial, state, and university organizations participated in cooperative limnological surveys of Lake Erie in September 1959 and August 1960 to determine the extent and severity of the low dissolved-oxygen content of the hypolimnetic waters. Observations were restricted to the central basin in 1959, but were lake-wide in 1960....

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...
