Catalytic determination of vanadium in water
M. J. Fishman, M. W. Skougstad
1964, Analytical Chemistry (36) 1643-1646
A kinetic determination of V(V) as a catalyst was spectrophotometrically performed by using the indicator reaction of Gallamine blue (GB+) and bromate at pH 2.0. The reaction was followed by measuring absorbance change for a fixed-time of 3 min at 537 nm. The variables such as reagent...
Fused rock from Köfels, Tyrol
Daniel J. Milton
1964, Tschermaks Mineralogische und Petrographische Mitteilungen (9) 86-94
The vesicular glass from Köfels, Tyrol, contains grains of quartz that have been partially melted but not dissolved in the matrix glass. This phenomenon has been observed in similar glasses formed by friction along a thrust fault and by meteorite impact, but not in volcanic glasses. The explosion of a...
Spectrophotometric determination of fluorine in silicate rocks
L. C. Peck, V. C. Smith
1964, Talanta (11) 1343-1347
The rock powder is sintered with a sodium carbonate flux containing zinc oxide and magnesium carbonate, the sinter-cake leached with water and the resulting solution filtered. Fluorine is separated from the acidified filtrate by steam distillation and determined spectrophotometrically by means of a zirconium-SPADNS reagent. If...
Minor-element composition and organic carbon content of marine and nonmarine shales of Late Cretaceous age in the western interior of the United States
H. A. Tourtelot
1964, Geochimica et Cosmochimica Acta (28) 1579-1604
The composition of nonmarine shales of Cretaceous age that contain less than 1 per cent organic carbon is assumed to represent the inherited minor-element composition of clayey sediments delivered to the Cretaceous sea that occupied the western interior region of North America. Differences in minor-element content between these samples and...
The spottail shiner in Lower Red Lake, Minnesota
Lloyd L. Smith Jr., Robert H. Kramer
1964, Transactions of the American Fisheries Society (93) 35-45
On the basis of 14,564 spottail shiners (Notropis hudsonius) from Red Lakes, Minnesota, growth rates, strength of year classes, and food utilization were studied. Males and females had different body-scale relationships, and females grew faster than males. There was high correlation between water temperature and growth rate. Strength of year...
Life history of lake herring in Lake Superior
William R. Dryer, Joseph Beil
1964, Fishery Bulletin (63) 493-530
The average annual commercial catch of lake herring (Coregonus artedi) in U.S. waters of Lake Superior was nearly 12 million pounds in 1929-61. This production contributed 62.4 percent of the total U.S. take of lake herring for the Great Lakes. About 90 percent of the annual catch is...
Status of the deepwater cisco population of Lake Michigan
Stanford H. Smith
1964, Transactions of the American Fisheries Society (93) 155-163
The species and size composition and the abundance of the cisco (Leucichthys spp.) population of Lake Michigan have undergone drastic changes since the sea lamprey became established in the 1940's. The changes were measured by the catches of gill nets of identical specifications fished at the same seasons, depths, and...
Age, growth, sex ratio, and maturity of the whitefish in central Green Bay and adjacent waters of Lake Michigan
Donald Mraz
1964, Fishery Bulletin of the U.S. Fish and Wildlife Service (63) 619-634
This study is based on 1,023 whitefish, Coregonus clupeaformis (Mitchill)--819 in seven samples from five localitites in central Green Bay in 1948-49 and 1851-52 and 204 in a single 1948 collection from northwestern Lake Michigan proper. Records of age indicated unusual strength for only one year class--1943 which strongly dominated...
A horizontal sampler for collection of water samples near the bottom
Leonard S. Joeris
1964, Limnology and Oceanography (9) 595-598
The need to obtain adequate water samples immediately above a lake bottom or at a precisely defined depth is not new. The problem is of particular concern in a large section of central Lake Erie, where dissolved oxygen concentration may be reduced to 1 ppm...
Ground water in North America
Harold E. Thomas, Luna Bergere Leopold
1964, Science (143) 1001-1006
The fast-growing demands on this natural resource expose a need to resolve many hydrologic unknowns....

U.S. Geological Survey
1964, Report
This data release is a compilation that presents water-quality data for the period October 1962 to September 1963 for the sites listed on page 2. These preliminary data are subject to revision before final publication in the annual series of U.S. Geological Survey Water-supply papers entitled Quality of surface waters...
Selected hydrologic data, upper Sevier River basin, Utah
Carl H. Carpenter, Gerald B. Robinson Jr., Louis Jay Bjorklund
1964, Utah Basic-Data Report 8
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 1961-63 by the U.S. Geological Survey in cooperation...

Geology and ground-water conditions of Clark County, Washington, with a description of a major alluvial aquifer along the Columbia River
Maurice John Mundorff
1964, Water Supply Paper 1600
This report presents the results of an investigation of the ground-water resources of the populated parts of Clark County. Yields adequate for irrigation can be obtained from wells inmost farmed areas in Clark County, Wash. The total available supply is sufficient for all foreseeable irrigation developments. In a few local...
