Similarities between the thick-skinned Blue Ridge anticlinorium and the thin-skinned Powell Valley anticline
L. D. Harris (compiler)
1979, Geological Society of America Bulletin (90) 525-539
The Blue Ridge anticlinorium in northern Virginia is a part of an integrated deformational system spanning the area from the Piedmont to the Appalachian Plateaus. Deformation intensity within the system decreases from east to west. Differences of opinion have emerged concerning the central Appalachians as to whether the basement rocks...

Middle Miocene marine diatoms from the Hawthorn Formation within the Ridgeland Trough, South Carolina and Georgia
William H. Abbott, George W. Andrews
1979, Micropaleontology (25) 225-271
Diatomaceous sediments in outcrops of the Miocene Hawthorn Formation at Dawsons Landing in South Carolina and at Berrys Landing in Georgia, have yielded a total of 111 marine diatom taxa. Varving of the diatomaceous clay suggests that the diatoms were deposited in a restricted basin or lagoonal area that had...
Depth occurrences of foraminifera along the southeastern United States
R. Todd
1979, Journal of Foraminiferal Research (9) 277-301
The shelf samples are rich with their diversity increasing seaward to the edge of the shelf or the upper part of the continental slope. Miliolids and elphidiids predominate on the inner part of the shelf. Their dominance gives way to textulariids and bolivinids as the shelf edge is approached. Cassidulinids...

Geodolite measurements of deformation near Hollister, California, 1971-1978
James C. Savage, W.H. Prescott, Michael Lisowski, N. King
1979, Journal of Geophysical Research B: Solid Earth (84) 7599-7615
A 24‐station trilateration network spanning the San Andreas and Calaveras faults near Hollister, California, has been surveyed each year between 1971 and 1978, inclusive. Two moderate (ML = 5) earthquakes have occurred within the network during the interval. No convincing preseismic or coseismic anomalies associated with those earthquakes have been identified....
Deformation across the Salton Trough, California, 1973-1977
James C. Savage, W.H. Prescott, Michael Lisowski, N. King
1979, Journal of Geophysical Research B: Solid Earth (84) 3069-3079
A trilateration network extending across the San Andreas, San Jacinto, and Elsinore faults in the vicinity of the Salton Sea, California, has been surveyed to very high precision several times in the 5‐year interval 1973–1977. The average strain across the entire network is essentially a uniaxial north‐south contraction at the...
Strain accumulation rates in the western United States between 1970 and 1978
W.H. Prescott, James C. Savage, W. T. Kinoshita
1979, Journal of Geophysical Research B: Solid Earth (84) 5423-5435
The rate of dilatation and the rate and direction of shear have been determined from trilateration data for 23 Geodolite networks in the western United States. Sixteen nets are located along the San Andreas fault system between Point Reyes, California, and the United States‐Mexico border. Other locations are across the...
Geodimeter measurements of strain during the Southern California Uplift
James C. Savage, W.H. Prescott
1979, Journal of Geophysical Research B: Solid Earth (84) 171-177
A review of geodimeter measurements made along the ‘big‐bend’ section of the San Andreas fault in southern California indicates no significant increment in strain during the period of major uplift (late 1959 to mid‐1963). Specifically, no evidence of an increment in compressional strain normal to the San Andreas fault at...
Recent crustal uplift in Yellowstone National Park
J.R. Pelton, R. B. Smith
1979, Science (206) 1179-1182
Comparison of precise leveling measurements made in 1923 with those made in 1975, 1976, and 1977 reveals that the 600,000-year-old Yellowstone caldera is being uplifted relative to its surroundings. Maximum relative uplift since 1923 is in excess of 700 millimeters - about 14 millimeters vertically per year. The most likely...

Managing the rippling stream: decisionmaking in natural resource administration
Harvey R. Doerksen, Berton L. Lamb
1979, Journal of the American Water Resources Association (15) 1707-1715
This article addresses the conflict which exists within the water resources decisionmaking arena over the allocation of water for instream uses. The discussion reviews the literature on public administration regarding decisionmaking, and is based on research performed by the authors which synthesizes a model of decisionmaking. This model can be...
Tolerance of developing salmonid eggs and fry to nitrate exposure
John W. Kincheloe, Gary A. Wedemeyer, David L. Koch
1979, Bulletin of Environmental Contamination and Toxicology (23) 575-578
This paper reports on tests which show significant effects on early salmonid life stages of nitrates at levels commonly found in groundwaters in geographical areas that are influenced by fertilizer application. It has long been known, from fish cultural experience, that in certain site specific locations, chronic problems can be...

1979, Science (206) 927-950
Voyager 2, during its encounter with the Jupiter system, provided images that both complement and supplement in important ways the Voyager 1 images. While many changes have been observed in Jupiter's visual appearance, few, yet significant, changes have been detected in the principal atmospheric currents. Jupiter's ring system...
Chemical changes in an industrial waste liquid during post-injection movement in a limestone aquifer, Pensacola, Florida
G. G. Ehrlich, E.M. Godsy, C.A. Pascale, John Vecchioli
1979, Groundwater (17) 562-573
An industrial waste liquid containing organonitrile compounds and nitrate ion has been injected into the lower limestone of the Floridan aquifer near Pensacola, Florida since June 1975. Chemical analyses of water from monitor wells and backflow from the injection well indicate that organic carbon compounds are converted to CO2 and...
Magnitude of shear stress on the San Andreas fault: Implications of a stress measurement profile at shallow depth
Mark D. Zoback, J.C. Roller
1979, Science (206) 445-447
A profile of measurements of shear stress perpendicular to the San Andreas fault near Palmdale, California, shows a marked increase in stress with distance from the fault. The pattern suggests that shear stress on the fault increases slowly with depth and reaches a value on the order of the average...
Robust estimation of population size when capture probabilities vary among animals
K.P. Burnham, W.S. Overton
1979, Ecology (60) 927-936
A model is given for multiple recapture studies on closed populations which allows capture probabilities to vary among individuals. The capture probability of each individual is assumed to be constant over time. Based on this model we give a nonparametric estimation procedure for population size. The estimator...
Measurement of fluid velocity using temperature profiles: Experimental verification
K. Cartwright
1979, Journal of Hydrology (43) 185-194
Temperature profiling has been used to predict the rate and direction of groundwater movement. A controlled field experiment was conducted to ascertain the validity of the rate calculations made using this method. The vertical velocity, or leakage, of groundwater between two aquifers was calculated utilizing both hydrologic and temperature measurements...
Contribution of groundwater modeling to planning
J.E. Moore
1979, Journal of Hydrology (43) 121-128
The consideration of groundwater in water-resource planning frequently has been neglected because many planners believed that groundwater could not be adequately evaluated in terms of availability, quality, cost of development, or effect of development on the surface-water supply. The development of predictive groundwater models now provides the water planner with...
Hydraulic potential in Lake Michigan bottom sediments
K. Cartwright, C.S. Hunt, G.M. Hughes, R.D. Brower
1979, Journal of Hydrology (43) 67-78
The magnitude and direction of groundwater flux in the bottom sediments of Lake Michigan were deduced from measurements made during three shipboard cruises between 1973 and 1975. These factors affect the geochemical environment of the sediments and therefore the distribution of trace elements reported to be present. The near-shore, sandy-bottom...
