Geochemical interpretations of groundwater flow systems
William Back, Bruce B. Hanshaw
1971, Journal of the American Water Resources Association (7) 1008-1016
Interest in the geochemistry of groundwater is increasing owing to the great number of current projects involving underground liquid waste storage, artificial recharge of potable water, accidental contamination of groundwater bodies, sanitary landfills, and pollution monitoring. Geochemical techniques used to facilitate the understanding of a groundwater...
A device for monitoring radio-marked animals
D.S. Gilmer, V.B. Kuechle, I.J. Ball Jr.
1971, Journal of Wildlife Management (35) 829-832
A simple, portable, and economical recording system consisting of a receiver, signal conditioner, recorder, and power source is described. The system was designed to monitor the signal strength from a radio-marked animal at a particular location. Information is stored on recorder chart paper. Radio-marked ducks have been successfully monitored at...
Waterfowl nesting on interstate highway right-of-way in North Dakota
R.B. Oetting, J.F. Cassel
1971, Journal of Wildlife Management (35) 774-781
We studied 630 acres of roadside along 23 miles of Interstate 94 in Stutsman County, North Dakota, to assess wildlife values of highway rights-of-way. We found 422 duck nests that had an overall success of 57 percent in 1968, 1969, and 1970. Mammalian predators were responsible for 85 percent of...
Effects of introducing foxes and raccoons on herring gull colonies
J.A. Kadlec
1971, Journal of Wildlife Management (35) 625-636
Red foxes (Vulpes fulva) and raccoons (Procyon lotor) released at colonies of herring gulls (Larus argentatus) on islands off the Massachusetts coast effectively eliminated the production of young gulls. Annual predator introductions for 2-4 years caused major reductions in colony size and occasionally total abandonment of the island as a...
Channel catfish virus: A new herpesvirus of ictalurid fish
K. Wolf, R. W. Darlington
1971, Journal of Virology (8) 525-533
Channel catfish virus was studied in ictalurid fish cell culture, the only system of fish, amphibian, avian, and mammalian cells found to be susceptible. Channel catfish virus infection resulted in intranuclear inclusions and extensive syncytium formation. Replication occurred from 10 to 33 C, but not higher. Best growth was from...
A starling-deterrent wood duck nest box
Frank B. McGilvrey, Francis M. Uhler
1971, Journal of Wildlife Management (35) 793-797
In many parts of the United States, the starling (Sturnus vulgaris) has I become a serious competitor for nest boxes erected for wood ducks (Aix sponsa). Research at the Patuxent Wildlife Research Center and at Eastern Neck National Wildlife Refuge near Rock Hall, Maryland, demonstrated that horizontal nest structures with...
Ground water in the Aden sector of Southern Arabia
D.J. Cedarstrom
1971, Ground Water (9) 29-34
A reconnaissance of parts of the former West Aden Protectorate enables a characterization of the dominant hydrologic elements to be made. In this desert environment intermittent streams from the east‐west range of mountains provide considerable water for flood irrigation and groundwater recharge of alluvial fans along the Gulf of Aden....
Geological aspects of the May 31, 1970, Perú earthquake
George Plafker, G. E. Ericksen, Jamie Fernandez Concha
1971, Bulletin of the Seismological Society of America (61) 543-578
Geological effects of the destructive May 31, 1970, Perú earthquake (Ms = 7.7) extended over roughly 65,000 km2 of west-central Perú. Earthquake-triggered slope failures of all types that occurred throughout the mountainous parts of the region extensively damaged transportation routes and irrigation canals and temporarily dammed some rivers and lakes....
Plate tectonics and magmatic evolution
James Gilluly
1971, Bulletin of the Geological Society of America (82) 2383-2396
The validity of the general idea of plate tectonics is accepted; the magmas evolved along the spreading ridges are thought to be largely tholeiitic basalt, although alkalic olivine basalt and...
Protective pumping to reduce aquifer pollution, Glynn County, Georgia
Dean O. Gregg
1971, Groundwater (9) 21-29
Water-level declines in the principal artesian aquifer have created a head imbalance between the aquifer and an underlying brackish-water zone containing up to 4,550 mg/1 chloride. The brackish-water zone leaks brackish water into the aquifer through several breaks in a confining unit.A relief well tapping the brackish-water zone was drilled...
Distribution and age of high-grade blueschists, associated eclogites, and amphibolites from Oregon and California
R. G. Coleman, Marvin A. Lanphere
1971, Bulletin of the Geological Society of America (82) 2397-2412
Isolated blocks of high-grade blueschist and amphibolite facies metamorphic rocks occur within the Jurassic and Cretaceous eugeosynclinal deposits of the Coast Ranges of southwestern Oregon and California. The blocks range in size from individual rock masses commonly 5 to 1,000 ft in diameter to a...
Continuous magnetic profiles near ground level as a means of discriminating and correlating rock units
M. F. Kane, D. S. Harwood, N. L. Hatch Jr.
1971, Bulletin of the Geological Society of America (82) 2449-2456
Continuous magnetic profiles were recorded by a truck-mounted magnetometer along road traverses over stratified metamorphic rocks and plutonic igneous rocks of the New England Appalachians. The records show a series of distinctive, highly detailed magnetic anomalies which closely reflect the nature and distribution of near-surface...
Lunar Apennine-Hadley region: Geological implications of earth-based radar and infrared measurements
S.H. Zisk, M. H. Carr, H. Masursky, R.W. Shorthill, T.W. Thompson
1971, Science (173) 808-812
Recently completed high-resolution radar maps of the moon contain information on the decimeter-scale structure of the surface. When this information is combined with eclipse thermal-enhancement data and with high-resolution Lunar Orbiter photography, the surface morphology is revealed in some detail. A geological history for certain features and...
Geologic setting of the Apollo 14 samples
G.A. Swann, N.J. Trask, M. H. Hait, R. L. Sutton
1971, Science (173) 716-719
The Apollo 14 lunar module landed in a region of the lunar highlands that is part of a widespread blanket of ejecta surrounding the Mare Imbrium basin. Samples were collected from the regolith developed on a nearly level plain, a ridge 100 meters high, and a blocky ejecta deposit around...
A lower paleozoic paleoaquifer; the Kingsport Formation and Mascot dolomite of Tennessee and southwest Virginia
Leonard D. Harris
1971, Economic Geology (66) 735-743
The Kingsport Formation (Lower Ordovician) in one section may be composed of two dominant rock types--limestone and medium to coarsely crystalline dolomite--whereas in an adjacent section, most of the formation may be largely composed of breccia. The breccia bodies, which are interpreted to be solution-collapse features, range in width from...
Banquet speech "Man's conquest of energy, its ecological and human consequences"
M. King Hubbert
1971, IEEE Transactions on Nuclear Science (18) 18-35
The world's energy resources suitable for power production are of two classes: (1) various channels of the continuous energy flux from extraterrestrial sources, and from the earth's interior, and (2) chemical, thermal, and nuclear energy stored in the outer part of the lithosphere and in the...
Relations of folded dikes and Precambrian polyphase deformation, Gardner Lake area, Beartooth Mountains, Wyoming
Lawrence C. Rowan, Paul A. Mueller
1971, Bulletin of the Geological Society of America (82) 2177-2185
Two cross-cutting mafic dikes in the headwall of Gardner Lake in the eastern Beartooth Mountains, Wyoming, have structural relations with Archean migmatite and gneiss that suggest intrusion between deformational phases recognized in the eastern part of the range. Fabric data show that the older dike,...
