Cholinesterase (ChE) response and related mortality among birds fed ChE inhibitors
J. Larry Ludke, Elwood F. Hill, Michael P. Dieter
1975, Archives of Environmental Contamination and Toxicology (3) 1-21
Patterns of mortality and inhibition of brain and plasma ChE in birds treated with ChE inhibitors were studied in an attempt to determine the validity of using ChE activity as a monitoring and diagnostic technique. Analysis of brain ChE activity proved to be reliable for diagnosing and monitoring effects of...
Geologic setting and chemical characteristics of hot springs in west-central Alaska
Thomas Miller, Ivan Barnes, William Wallace Patton Jr.
1975, Journal of Research of the U.S. Geological Survey (3) 149-162
Numerous hot springs occur in a variety of geologic provinces in west-central Alaska. Granitic plutons are common to all the provinces, and the hot springs are spatially associated with the contacts of these plutons. Of 23 hot springs whose bedrock geology is known, all are within 4.8 km (3 mi)...
Pyrrolidone - a new solvent for the methylation of humic acid
R.L. Wershaw, D.J. Pinckney, S.E. Booker
1975, Journal of Research of the U.S. Geological Survey (3) 123-126
In the past, humic acid has been methylated by suspending it in a solution of diazomethane in diethyl ether, and degrading the partly methylated humic acid to release those parts of the molecule that were methylated. Only small fragments of the molecule have been identified by this technique. In the...
Weights, growth, and survival of timber wolf pups in Minnesota
V. Van Ballenberghe, L.D. Mech
1975, Journal of Mammalogy (56) 44-63
Weights, growth rates, canine tooth lengths, and survival data were obtained from 73 wild wolf (Canis lupus) pups that were 8 to 28 weeks old when live-trapped in three areas of northern Minnesota from 1969 to 1972. Relative weights of wild pups are expressed as percentages of a standard weight...
Blood analyses of wolf pups and their ecological and metabolic interpretation
U.S. Seal, L.D. Mech, V. Van Ballenberghe
1975, Journal of Mammalogy (56) 64-75
Blood samples were obtained from 32 wolf (Canis lupus) pups live-trapped over a three-year period in northern Minnesota. The results of 21 laboratory analyses of hematology and blood chemistry are tabulated and analyzed in terms of study area, age, sex, and year of collection. Mean values are compared to those...
Mount St. Helens volcano: Recent and future behavior
D. R. Crandell, D. R. Mullineaux, M. Rubin
1975, Science (187) 438-441
Mount St. Helens volcano in southern Washington has erupted many times during the last 4000 years, usually after brief dormant periods. This behavior pattern suggests that the volcano, last active in 1857, will erupt again - perhaps within the next few decades. Potential volcanic hazards of several kinds should be...
The distribution of seepage within lakebeds
M.S. McBride, H.O. Pfannkuch
1975, Journal of Research of the U.S. Geological Survey (3) 505-512
The mutual exchange of water between lakes and contiguous permeable ground-water bodies, which are thin relative to the diameter of the lakes, was modeled digitally. A significant rate of seepage was found to extend only a relatively short distance from shore, thus forming a narrow band around the lake's perimeter....
Regional impact of water resource investments in an developing area
Emil Attanasi
1975, Journal of the American Water Resources Association (11) 69-76
Regional development and industrialization patterns are investigated and related via regression analysis to water resource investments for the island of Puerto Rico. Although results of this study indicate such investments have little immediate or short‐term impact, significant relationships and variations in regional responses appear over longer time periods. This is...
Geology of Bulgaria: A review
Richard M. Foose, Frank T. Manheim
1975, AAPG Bulletin (59) 303-335
Bulgaria is in southeastern Europe between reasonably well-described areas of predominantly Alpine crustal deformation on the north and northwest (Carpathians in Romania, Hungary, and Czechoslovakia; Alps in Austria), on the east (Pontides and Taurides in Turkey), and on the west and south (Dinaric Alps in Yugoslavia; Pindos Mountains...
Earthquakes, active faults, and geothermal areas in the Imperial Valley, California
D.P. Hill, P. Mowinckel, L.G. Peake
1975, Science (188) 1306-1308
A dense seismograph network in the Imperial Valley recorded a series of earthquake swarms along the Imperial and Brawley faults and a diffuse pattern of earthquakes along the San Jacinto fault. Two known geothermal areas are closely associated with these earthquake swarms. This seismicity pattern demonstrates that seismic slip is...
Mechanism of Formation of Pillow Lava
James G. Moore
1975, American Scientist (63) 269-277
Much of the ocean floor is covered by lava of a distinctive character. The lava appears to be made up of closely packed ellipsoidal masses about the size and shape of pillows - hence the term pillow lava. Only within the last few years has the abundance of pillow lava...
A brief history of the U.S. Geological Survey
Water Resources Division, U.S. Geological Survey, Mary C. Rabbitt
1975, Report
Established by an Act of Congress in 1879 and charged with responsibility for "classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain," the U. S. Department of the Interior's Geological Survey has been the Nation's principal source of information about...
Geohydrology and water quality of the Mississippi River alluvial aquifer, northeastern Louisiana
Merrick S. Whitfield Jr.
1975, Water Resources Technical Report 10
The Mississippi River alluvial aquifer in northeastern Louisiana is in the alluvium of the Mississippi, Arkansas, and Ouachita Rivers and underlies approximately 5,000 square miles (13,000 square kilometers) in the Mississippi River valley. The aquifer, of Pleistocene age, is a southeastward-thickening wedge of sand and gravel that ranges in thickness...
Lakes of Oregon, Volume 3: Hood River, Multnomah, Washington and Yamhill Counties
M.V. Shulters
1975, Report
An inventory of lakes and reservoirs of Oregon is essential for a complete evaluation of the total surface-water supply of the State and to provide a basis for answering questions about Oregon's lakes. Much of the information on lakes and reservoirs previously collected by Federal and State agencies has never...
The EROS Data Center
Water Resources Division, U.S. Geological Survey
1975, Report
The EROS Data Center, 16 miles (25 km) northeast of Sioux Falls, South Dakota, is operated by the EROS Program to provide access to NASA's LANDSAT [formerly Earth Resources Technology Satellite (ERTS)] imagery, aerial photography acquired by the U.S. Department of the Interior, and photography and imagery acquired by the...

Building stones of our Nation's Capital
Charles F. Withington
1975, Report
The buildings of our Nation's Capital serve as an unusual geologic display, for the city has been constructed with rocks from quarries throughout the United States and many distant lands. Each building is a unique museum that not only displays the important features of various stones and the geologic environment...
Water-resources investigations of the U.S. Geological Survey in the northern Great Plains coal region of Wyoming, Montana, and North Dakota, 1975
Water Resources Division, U.S. Geological Survey
1975, Report
The Geological Survey's Water Resources Division has for many years maintained a program of water-resources investigations that includes the coal regions of Wyoming, Montana, and North Dakota. These programs have been supported by State and local agencies and by other agencies of the Federal government, largely to provide data for...
