Microearthquake--array studies of the seismicity in Southeast Missouri
W. Stauder
1977, Earthquake Information Bulletin (USGS) (9) 8-13
In 1811-12, a series of disastrous earthquakes struck the southeast Missouri region (see "The Mississippi Valley earthquakes of 1811 and 1812" by Otto W. Nuttli in the Earthquake Information Bulletin, March-April 1974). Earthquake activity continues in the area at present, showing that the seismic hazard is still there. We know little about the...
Earthquake history of Vermont
C. A. von Hake
1977, Earthquake Information Bulletin (USGS) (9) 27-28
Seven earthquakes of intensity V or greater on the Modified Mercalli Scale (MM) are known to have originated within Vermont. Many additional shocks centered in other New England States and Canada have been strongly felt in Vermont. ...
Measuring the size of an earthquake
W. Spence
1977, Earthquake Information Bulletin (USGS) (9) 21-23
Earthquakes occur in a broad range of sizes. A rock burst in an Idaho silver mine may involve the fracture of 1 meter of rock; the 1965 Rat island earthquake in the Aleutian arc involved a 650-kilometer lenght of Earth's crust. Earthquakes can be even smaller and even larger. if...
Studying the Earth from space
Water Resources Division, U.S. Geological Survey
1977, Report
Pictures of the Earth's surface obtained from satellites are providing scientists with new tools to investigate the Earth and its environment. At the same time, a growing population and an ever-expanding technology place unprecedented demands on natural resources. Man can no longer treat his resources strictly according to immediate economic...
Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD
Chandler S. Robbins
1977, North American Bird Bander (2) 83-83
Robbins Nest is located on the fall line one-half mile below Rocky Gorge Reservoir. During the fall migration, about 8 nets are run on the upper part of the 3 acres (edge of the lawn, the garden, under the Virginia Pines, and the upper edge of the mature oak woods...
Can we control earthquakes?
B. Raleigh
1977, Earthquake Information Bulletin (USGS) (9) 4-7
In 1966, it was discovered that high pressure injection of industrial waste fluids into the subsurface near Denver, Colo., was triggering earthquakes. While this was disturbing at the time, it was also exciting because there was immediate speculation that here at last was a mechanism to control earthquakes.  ...
The chronic toxicity of 3-chloro-4-methyl benzamine HCl to birds
Edward W. Schafer Jr., Ronald B. Brunton, Donald J. Cunningham, Norman F. Lockyer
1977, Archives of Environmental Contamination and Toxicology (6) 241-248
3-Chloro-4-methyl benzamine HCl (DRC-1339), an avian toxicant, was fed to five species of birds for periods up to 120 days. The 30-day LC50 of uniformly treated feed for starlings was 4.7 ppm and the 90-day LC50 was 1.0 ppm. The 28-day LC50 for coturnix was 18 ppm. The 30-day LC50 for pigeons was...

Rising ground-water level in downtown Louisville, Kentucky, 1972-1977
J. M. Kernodle, D. V. Whitesides
1977, Water-Resources Investigations Report 77-92
Ground-water levels in the alluvial aquifer in Louisville, Jefferson County, Kentucky, are rising at a rate which could cause wet basements and possible structural damage tc buildings in the downtown area by 1982. The predicted water level for 1982 is based on the nearly linear increase which has been observed...
Modeling chloride movement in the alluvial aquifer at the Rocky Mountain Arsenal, Colorado
Leonard F. Konikow
1977, Water Supply Paper 2044
A solute-transport model that can be used to predict the movement of dissolved chemicals in flowing ground water was applied to a problem of ground-water contamination at the Rocky Mountain Arsenal, near Denver, Colo. The model couples a finite-difference solution to the ground-water flow equation with the method-of-characteristics solution to...
Reassociation and hybridization properties of DNAs from several species of fish
A.J. Gharrett, R.C. Simon, J.D. McIntyre
1977, Comparative Biochemistry and Physiology, Part B: Comparative Biochemistry (56) 81-85
Reassociation and hybridization properties from spectrophotometric studies of DNAs from 10 species of fish indicate:1. Great diversity in the amounts of repeated sequences in the genomes of different species - more specialized fish had less redundancy.2. Large differences in the complexities of the DNAs - more specialized fish had less...
Classification of the hydrologic settings of lakes in the north central United States
Thomas C. Winter
1977, Water Resources Research (13) 753-767
The hydrologic settings of 150 lakes in the north central United States were investigated by principal component analysis as a first attempt to develop a general classification of the hydrologic settings of lakes. Precipitation-evaporation balance and the water quality variables have high loadings on the first principal component. Highest loadings...

Geochemical and hydrologic data for wells and springs in thermal-spring areas of the Appalachians
W.A. Hobba Jr., J.C. Chemerys, D.W. Fisher, F. J. Pearson Jr.
1977, Water-Resources Investigations Report 77-25
Current interest in geothermal potential of thermal-spring areas in the Appalachians enhances the value of data on thermal springs and wells in these areas. This report presents maps showing locations of selected springs and wells and tables of physical and chemical data pertaining to these wells and springs. The chemical...
