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...
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...
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...
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...
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,...
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...
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...
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...
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...

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...

Age, growth, and maturity of round whitefish of the Apostle Islands and Isle Royale Regions, Lake Superior
Merryll M. Bailey
1963, Fishery Bulletin (63) 63-75
The round whitefish has been of some commercial importance in the upper Great Lakes but production in Lake Superior has generally been small; the United States average was 26,600 pounds for 1929-59. This study is based on 1,173 fish collected in the Apostle Islands in 1958-60 and 103 collected at...

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...
Age and growth of the whitefish in Lake Superior
William R. Dryer
1963, Fishery Bulletin (63) 77-95
The average annual commercial production of whitefish in the U.S. waters of Lake Superior dropped from 2,194,000 pounds in 1879-1908 to 504,000 pounds in 1911-59. The modern production, though far below the earlier, has accounted for more than 10 percent of the total value of the fishery in all...
Some phases of the life history of the trout-perch
John L. Magnuson, Lloyd L. Smith
1963, Ecology (44) 83-95
The trout-perch, Percopsis omiscomaycus (Walbaum), is one of the more abundant forage fishes in the larger lakes of midwestern United States and central Canada where walleye, Stizostedion v. vitreum (Mitchill), yellow perch, Perca flavescens (Mitchill), and coregonids predominate. It has been suggested that it may have considerable effect on...
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...
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....
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...

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 1935-62 by the U.S. Geological Survey...
