Toxicity of five forest insecticides to cutthroat trout and two species of aquatic invertebrates
D. F. Woodward, W.L. Mauck
1980, Bulletin of Environmental Contamination and Toxicology (25) 846-854
The Northern Rocky Mountain region has had scattered infestation of the western spruce budworm Christoneura occidentalis since the early 1900's (U.S. DEPARTMENT OF AGRICULTURE (USDA) 1976b). On the basis of aerial surveys in 1975, TUNNOCK et al. (1976), estimated that budworm defoliation occurred on 2,278,804 acres of six National Forests...

Accuracy of an estuarine hydrodynamic model using smooth elements
Roy A. Walters, Ralph T. Cheng
1980, Water Resources Research (16) 187-195
A finite element model which uses triangular, isoparametric elements with quadratic basis functions for the two velocity components and linear basis functions for water surface elevation is used in the computation of shallow water wave motions. Specifically addressed are two common uncertainties in this class of two-dimensional hydrodynamic models: the...
Epizootic of coccidiosis in free-flying lesser scaup (Aythya affinis)
R. M. Windingstad, M.E. McDonald, Louis N. Locke, S.M. Kerr, J.A. Sinn
1980, Avian Diseases (24) 1044-1049
A coccidiosis epizootic has occurred in lesser scaup (Aythya affinis) at Bluestem Reservoir in eastern Nebraska during the spring in each of three recent years: 1976-1978. Losses peaked during the period from mid-March through April. As much as 29% of the peak population of scaup using the reservoir died. Necropsies...
Upper Wisconsinan till recovered on the continental shelf southeast of New England
Michael H. Bothner, Elliott C. Spiker
1980, Science (210) 423-425
Basal till was identified in two sediment cores collected about 69 kilometers southeast of Nantucket Island on the east and west sides of Great South Channel. These are the first samples of till collected on the outer continental shelf off the northeastern United States. The carbon-14 age of the total...

Calculation of gravity and magnetic anomalies of finite-length right polygonal prisms.
J. W. Cady
1980, Geophysics (45) 1507-1512
An equation is derived for the vertical gravity field due to a homogeneous body with polygonal cross‐section and finite strike‐length. The equation can be separated into the two‐dimensional (2-D) terms of Talwani et al. (1959) and exact terms for the contributions of the ends of the prism. Equations for the...
Geochemical exploration for uranium in playas
D. L. Leach, K.P. Puchlik, R.K. Glanzman
1980, Journal of Geochemical Exploration (13) 251-283
Playas and closed-basin lakes represent unique geochemical environments for the entrapment and concentration of mobile chemical elements. For this reason, playas may be considered as potentially favorable areas for the accumulation of uranium. We investigated playa sediments to determine their value as possible sample media for determining the presence...
Evaluation of organic matter, subsurface temperature and pressure with regard to gas generation in low-permeability Upper Cretaceous and Lower Tertiary sandstones in Pacific Creek area, Sublette and Sweetwater Counties, Wyoming.
B. E. Law, C. W. Spencer, N. H. Bostick
1980, Mountain Geologist (17) 23-35
The onset of overpressuring occurs at c.3,500 m, near the base of the U. Cretaceous Lance Formation. The development of overpressuring may involve several processes; however, interpretation of the available information indicates that active generation of large amounts of wet gas is one of the more important processes. The present...
Role of physical barriers in the control of sea lamprey (Petromyzon marinus)
J. B. Hunn, W.D. Youngs
1980, Canadian Journal of Fisheries and Aquatic Sciences (37) 2118-2122
Mechanical and electromechanical barriers played a significant role in the initial attempts to control sea lamprey (Petromyzon marinus) populations in the upper Great Lakes. More recently electromechanical weirs have been used to assess the relative abundance of spawning-run sea lampreys in Lake Superior. Development of an integrated control approach to...
Comparison of bed form variance spectra within a meander bend during flood and average discharge
R.A. Levey, B. Kjerfve, R.T. Getzen
1980, Journal of Sedimentary Petrology (50) 149-155
Time series analysis of streambed elevation in a meander bend along the Congaree River was used to determine the changes in bed form population succeeding a 16-year flood event. Bed forms observed during the flood event had a significantly greater total height variance...

Geochemistry, strontium isotope data, and potassium-argon ages of the andesite-rhyolite association in the Padang area, West Sumatra
G. W. Leo, C. E. Hedge, R. F. Marvin
1980, Journal of Volcanology and Geothermal Research (7) 139-156
Quaternary volcanoes in the Padang area on the west coast of Sumatra have produced two-pyroxene, calc-alkaline andesite and volumetrically subordinate rhyolitic and andesitic ash-flow tuffs. A sequence of andesite (pre-caldera), rhyolitic tuff and andesitic tuff, in decreasing order of age, is related to Maninjau caldera. Andesite compositions range from 55.0...
Flood risks and the willingness to purchase flood insurance
M.R. Karlinger, E. D. Attanasi
1980, Water Resources Research (16) 617-622
Computer simulation experiments were conducted to determine the effects of alternative sources of uncertainty on the willingness to pay for flood insurance. Two alternative insurance protection schemes were investigated: coinsurance and fixed coverage. The question investigated here is to what extent does the insurance scheme influence how purchasers respond to...
Distribution of modern benthic foraminifers on the New Jersey Outer Continental Shelf
C. Wylie Poag, H.J. Knebel, R. Todd
1980, Marine Micropaleontology (5) 43-69
We used samples from 21 stations within a 600 km2 area of the New Jersey Outer Continental Shelf to assess the effects of a hydrodynamic environment on the distribution and redistribution of benthic foraminifers. These samples show that, although the predominant genera (Elphidium, Cibicides, and Saccammina) are the same as...

Comment on 'A reinterpretation of the linear heat flow and heat production relationship for the exponential model of the heat production in the crust' by R.N. Singh & J.G. Negi.
A.H. Lachenbruch
1980, Geophysical Journal of the Royal Astronomical Society (63) 791-795
In their recent paper, Singh & Negi, (This journal, 57, 741-744) contend that if thd slope of the empirical linear relation between heat flow and heat production is interpreted as the decay-length of an exponential depth-distribution of sources, a discrepancy rises, whereas if it is interpreted as the depth of...
Morphology of Lonar Crater, India: Comparisons and implications
R.F. Fudali, D.J. Milton, K. Fredriksson, A. Dube
1980, The Moon and the Planets (23) 493-515
Lonar Crater is a young meteorite impact crater emplaced in Deccan basalt. Data from 5 drillholes, a gravity network, and field mapping are used to reconstruct its original dimensions, delineate the nature of the pre-impact target rocks, and interpret the emplacement mode of the ejecta. Our estimates of the pre-erosion...
