Tectonic stresses in the lithosphere: constraints provided by the experimental deformation of rocks.
S. H. Kirby
1980, Journal of Geophysical Research Solid Earth (85) 6353-6363
The strengths of rocks clearly place an upper limit on the stress that can be sustained by the upper half of the lithosphere. Laboratory data on rock rheology are generally lacking at intermediate temperatures and pressures on the important rock types expected in the lithosphere, so a definitive accounting of...

Wildlife hazards from Furadan 3G applications to rice in Texas
Edward L. Flickinger, Kirke A. King, W.F. Stout, M.M. Mohn
1980, Journal of Wildlife Management (44) 190-197
Mortality of birds, fish, frogs, crayfish, earthworms, and nontarget insects occurred in rice fields after treatments of Furadan 3G granules in 3 Texas counties in 1970 and 1973-75. Three western sandpipers (Ereunetes mauri), 1 pectoral sandpiper (Erolia melanotos), and 2 red-winged blackbirds (Agelaius phoeniceus) were found dead or moribund between...

Early concentrations of Brown Pelicans along southern Oregon coast
Charles J. Henny, J.A. Collins
1980, Murrelet (61) 99-100
The California Brown Pelican (Pelecanus occidentalis californicus), which nests in southern California and Mexico, wanders north along the coast after the breeding season, sometimes as far as southern British Columbia (A.O.U. 1957). Anderson and Anderson (1976) and Ainley (1972) report that Mexico-originating pelicans disperse north in late summer and fall,...

Enumeration of prairie wetlands with Landsat and aircraft data
D.S. Gilmer, E.A. Work Jr., J.E. Colwell, D.L. Rebel
1980, Photogrammetric Engineering and Remote Sensing (46) 631-634
A method is described for making an estimate of wetland numbers in the glaciated prairie region. A double-phase sampling approach is used which consists of first making a total census of wetlands using Landsat data, and then adjusting the Landsat results on the basis of samples derived from high resolution...
Classification of sea lamprey (Petromyzon marinus) attack marks on Great Lakes lake trout (Salvelinus namaycush)
Everett Louis King Jr.
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 1989-2006
Criteria for the classification of marks inflicted by sea lamprey (Petromyzon marinus) into nine categories were developed from laboratory studies in an attempt to refine the classification system used in field assessment work. These criteria were based on characteristics of the attachment site that could be identified under field conditions...
Sterility method of pest control and its potential role in an integrated sea lamprey (Petromyzon marinus) control program
Lee H. Hanson, Patrick J. Manion
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 2108-2117
The sterility method of pest control could be an effective tool in the sea lamprey (Petromyzon marinus) control program in the Great Lakes. Some of the requirements for its successful application have been met. A field study demonstrated that the release of male sea lampreys, sterilized by the injection of...
Nest site and colony characteristics of wading birds in selected Atlantic Coast colonies
Donald L. Beaver, Ronald G. Osborn, Thomas W. Custer
1980, The Wilson Bulletin (92) 200-220
Nests of 5 species of wading birds were identified and marked during the breeding season at 6 locations from Massachusetts to North Carolina. At the end of the breeding season 12 characteristics of nest-site location were measured. Nest locations were mapped to examine dispersion and nearest neighbor relationships. Multivariate analyses...
Reproductive success and nest attentiveness of mallard ducks fed Aroclor 1254
T. W. Custer, G. H. Heinz
1980, Environmental Pollution Series A: Ecological and Biological (21) 313-318
A dietary dosage of 25 ppm Aroclor 1254 fed to nine-month-old mallards Anas platyrhynchos for at least a month before egg-laying had no detrimental effect on reproductive success or nest attentiveness when hens were allowed to incubate their own eggs. The treatment caused no effect on number of hens laying, date of...
Changes in mortality of lake trout (Salvelinus namaycush) in Michigan waters of Lake Superior in relation to sea lamprey (Petromyzon marinus) predation, 1968-78
Richard L. Pycha
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 2063-2073
Total mortality rates of lake trout (Salvelinus namaycush) of age VII and older from eastern Lake Superior were estimated from catch curves of age distributions each year in 1968–78. The instantaneous rate of total mortality Z varied from 0.62 to 2.31 in close synchrony with sea lamprey (Petromyzon marinus) wounding rates on lake...
Minerals, lands, and geology for the common defence and general welfare, Volume 2, 1879-1904 : A history of geology in relation to the development of public-land, federal-science, and mapping policies and the development of mineral resources in the United States during the first 25 years of the U.S. Geological Survey
Mary C. Rabbitt
1980, Book
In the traditional view of the Survey's first 25 years, which are the subject of much of this volume, John Wesley Powell, with his broad view of science and advanced ideas of land and water in the West, is the heroic figure. Clarence King is dismissed as brilliant but with...
The comparison of usage and availability measurements for evaluating resource preference
Douglas H. Johnson
1980, Ecology (61) 65-71
Modern ecological research often involves the comparison of the usage of habitat types or food items to the availability of those resources to the animal. Widely used methods of determining preference from measurements of usage and availability depend critically on the array of components that the researcher, often with a...
Age and growth of rock bass in eastern Lake Ontario
David R. Wolfert
1980, New York Fish and Game Journal (27) 88-90
To test the reliability of current techniques, five biologists appraised the ages of 200 quail from a random sample of wings collected during the 1952-53 hunting season in Alabama. Attempt was made to distinguish adults from juveniles, to ascertain the stage of post-nuptial and post-juvenile molts, and to estimate the...

In 1977, the United States launched two unmanned Voyager spacecraft that were to take part in an extensive reconnaissance of the outer planets over a 12-year period visiting the environs of Jupiter, Saturn, Uranus, and Neptune. Their first encounter was with the complex Jupiter planetary system 400 million miles away....
Rate of mercury loss from contaminated estuarine sediments
Michael H. Bothner, R.A. Jahnke, M. L. Peterson, R. Carpenter
1980, Geochimica et Cosmochimica Acta (44) 273-285
The concentration of mercury in contaminated estuarine sediments of Bellingham Bay, Washington was found to decrease with a half-time of about 1.3 yr after the primary anthropogenic source of mercury was removed. In situ measurements of the mercury flux from sediments, in both dissolved and volatile forms, could not account...
High-sensitivity aeromagnetic survey of the U.S. Atlantic continental margin
John C. Behrendt, Kim D. Klitgord
1980, Geophysics (45) 1813-1846
The U.S. Geological Survey contracted a high-sensitivity, digital aeromagnetic survey that was flown over the U.S. Atlantic continental margin over a period of 15 months between 1974 and 1976. The 185,000 km of profile data have a relative accuracy approaching a few tenths of a nanotesla, which allowed compilation into...
Late Wisconsin and Holocene tectonic stability of the United States mid-Atlantic coastal region
B. W. Blackwelder
1980, Geology (8) 534-537
Deposits that formed in the intertidal zone during sea-level rise 12,000 to 9,000 yr ago have undergone very little differential vertical deformation in the area between New York City and South Carolina. The lack of north-south vertical deformation contrasts with tide-gauge and with...
