Earthquake fluctuations in wells in New Jersey
Charles R. Austin
1960, New Jersey Division of Water Policy and Supply Water Resources Circular 5
New Jersey is fortunate to be situated in a region that is relatively stable, geologically. For this reason scientists believe, on the basis of the best scientific evidence available, that the chances of New Jersey experiencing a major earthquake are very small. The last major earthquake on the east coast...
Factual data for public-supply wells and selected irrigation wells in Monmouth County, New Jersey
Leo A. Jablonski
1960, New Jersey Division of Water Policy and Supply Water Resources Circular 4
The investigation of the ground-water resources of Monmouth County is part of a Statewide water-resources program. This study was made by the U.S. Geological Survey in cooperation with the new Jersey Department of Conservation and Economic Development, Division of Water Policy and Supply. It was under the general direction of...
A geologic-profile plotter
O.T. Marsh
1960, Economic Geology (55) 201-204
Design and uses are described of an easy-to-construct instrument that facilitates construction of profiles of land surfaces, geologic formations, or other features such as profiles of geophysical or geochemical anomalies. Response to data from users of the instrument indicates that it is both faster and more convenient than previous methods. ...
Collection and preservation of fish and other materials exposed to pesticides
Oliver B. Cope
1960, Progressive Fish-Culturist (22) 103-108
The effects of pesticides on fish have become improtant to fish conservation since World War II, when DDT first came into common use. With the development of other potent insecticides and the increasing use of massive dosages in more recent years, the threat to fish and fish foods has increased....
A primer on water
Luna Bergere Leopold, Walter Basil Langbein
1960, Report
When you open the faucet you expect water to flow. And you expect it to flow night or day, summer or winter, whether you want to fill a glass or water the lawn. It should be clean and pure, without any odor.You have seen or read about places where the...
First-year growth of the walleye, Stizostedion vitreum vitreum (Mitchill), and associated factors in the Red Lakes, Minnesota
Lloyd L. Smith Jr., Richard L. Pycha
1960, Limnology and Oceanography (5) 281-290
First-year growth of the walleye, Stizostedion vitreum vitreum (Mitchill), was studied from 4,544 fish collected during the first summer of life in the Red Lakes in six seasons and from back calculations on 4,474 fish one year or more in age representing 17 year classes. Sexes did not differ in growth rate....
Lake Erie walleyes--again on the upswing?
Charles P. Seldon, Harry D. Van Meter
1960, Ohio Conservation Bulletin (24) 5-7
SUMMARY The effect of DDT dust on wildlife was studied at Camp Bullis, Bexar County, Texas, in the summer of 1947. Studies were made on a 206.6 acre plot that was treated with DDT for experimental control of the Lone Star tick (Amblyomrna americanum). A dust consisting...
The vertical migration of Mysis relicta in Lakes Huron and Michigan
Alfred M. Beeton
1960, Journal of the Fisheries Research Board of Canada (17) 517-539
During the day Mysis relicta could be taken only near the bottom of Lakes Huron and Michigan. In the evening they migrated into the overlying strata as the surface light intensity decreased from 15 to 1 foot-candles. Frequently the mysids migrated through the metalimnion when first ascending, but later in the night...
The American Fisheries Society
James W. Moffett
1960, U.S. Trout News (5) 20-22
In the course of studies designed to determine the calcium and phosphorus requirements of breeding bobwhite quail, it was found that best results were obtained when the Ca/P ratio in the diet was approximately 2.3:1. Variations in the Ca/P ratio produced significant differences in results when the level of...
Age and growth of the whitefish Coregonus clupeaformis, of Munising Bay, Lake Superior
Thomas A. Edsall
1960, Transactions of the American Fisheries Society (89) 323-332
This study is based on a sample of 415 whitefish collected in 1953 from an unexploited population in Munising Bay, Lake Superior. Gill-net and trawl catches had different length-frequency distributions and age compositions, but estimates of growth from the two catches were very similar. The body-scale relation is...
The stoneroller, Campostoma anomalum (Rafinesque), in Great Smoky Mountains National Park
R. E. Lennon, P. S. Parker
1960, Transactions of the American Fisheries Society (89) 263-270
The stoneroller (Campostoma anomalum) is one of the more important fish in Great Smoky Mountains National Park because of its abundance and habits. Although esteemed locally as a food and a bait fish, the stoneroller is exploited but little since the fishing regulations which govern the utilization of game fishes...
How volcanoes grow
J. P. Eaton, K. J. Murata
1960, Science (132) 925-938
Geology, geochemistry, and geophysics disclose the constitution and eruption mechanism of Hawaiian volcanoes....
The crystal structure of cesium biuranyl trisulphate, Cs2(UO2)2(SO4)3
M. Ross, H. T. Evans Jr.
1960, Journal of Inorganic and Nuclear Chemistry (15) 338-351
The crystal structure of the new compound Cs(UO2)2(SO4)3 has been determined by X-ray diffraction methods. The compound is tetragonal, space group P421m">P421m (D2d3), with a = 9·62 ± 0·02, c = 8·13 ± 0·01Å">c = 8·13 ± 0·01Å, and Z = 2; s.g. (calc.)...
Determination of niobium in the parts per million range in rocks
F. S. Grimaldi
1960, Analytical Chemistry (32) 119-121
A modified niobium thiocyanate spectrophotometric procedure relatively insensitive to titanium interference is presented. Elements such as tungsten, molybdenum, vanadium, and rhenium, which seriously interfere in the spectrophotometric determination of niobium, are separated by simple sodium hydroxide fusion and leach; iron and magnesium are used as carriers for the niobium. Tolerance...
Diagenesis of metabolites and a discussion of the origin of petroleum hydrocarbons
Irving A. Breger
1960, Geochimica et Cosmochimica Acta (19) 297-308
Proteins and carbohydrates are rapidly degraded to compounds of no direct interest in the problem of the origin of petroleum. Lignin, if carried into marine basins in the form of humic substances, is probably the major progenitor of kerogen rather than the precursor of petroleum. Pigments are but minor contributors...
Potentiometric titration and equivalent weight of humic acid
A. M. Pommer, Irving A. Breger
1960, Geochimica et Cosmochimica Acta (20) 30-44
The “acid nature” of humic acid has been controversial for many years. Some investigators claim that humic acid is a true weak acid, while others feel that its behaviour during potentiometric titration can be accounted for by colloidal adsorption of hydrogen ions. The acid character of humic acid has been...
Automatic measurements and computations for radiochemical analyses
J. N. Rosholt, J. R. Dooley Jr.
1960, Analytical Chemistry (32) 1093-1098
In natural radioactive sources the most important radioactive daughter products useful for geochemical studies are protactinium-231, the alpha-emitting thorium isotopes, and the radium isotopes. To resolve the abundances of these thorium and radium isotopes by their characteristic decay and growth patterns, a large number of repeated alpha activity measurements on...
Characteristic constants of 2,2',4'-trihydroxyazobenzene-5-sulfonic acid, a reagent for spectrophotometric analysis
Mary H. Fletcher
1960, Analytical Chemistry (32) 1822-1827
The dye 2,2',4'-trihydroxyazobenzene-5-sulfonic acid, has shown promise as a reagent for the determination of zirconium. As the literature contains very little information about this dye, basic data pertinent to its use as a reagent were determined. The sulfonic acid group and all three of the hydroxy groups show acidic characteristics....
