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...

Food of alewives, yellow perch, spottail shiners, trout-perch, and slimy and fourhorn sculpins in southeastern Lake Michigan
LaRue Wells
1980, Report
Stomachs of 1, 064 alewives (Alosa pseudoharengus), 1, 103 yellow perch (Perca flavescens), 246 spottail shiners (Notropis hudsonius), 288 trout-perch (Percopsis omiscomaycus), 454 slimy sculpins (Cottus cognatus), and 562 fourhorn sculpins (Myoxocephalus quadricornis) from Lake Michigan were examined for food contents. Fish were sampled primarily from March to November and...
The behavior of 14C and 13C in estuarine water: Effects of In situ CO2 production and atmospheric exchange
Elliott C. Spiker
1980, Radiocarbon (22) 647-654
The effects of nonconservative sources (inputs) and sinks (outputs) of carbon are indicated by the behavior of Δ14C and δ13C of the total dissolved inorganic carbon (ΣCO2) in San Francisco Bay and Chesapeake Bay. Isotopic distributions and model calculations indicate that in North San Francisco Bay the net CO2 flux to...
The composition, structure, and stability of guinier-preston zones in lunar and terrestrial orthopyroxene
Gordon L. Nord Jr.
1980, Physics and Chemistry of Minerals (6) 109-128
Lunar and terrestrial orthopyroxenes (Mg,Fe,Ca)2Si2O6 contain varying abundances of coherent, Ca-enriched Guinier-Preston (G.P.) zones. G.P. zones 5-6 unit cells thick have been found in one lunar sample whereas all other examples (lunar and terrestrial) are only one unit-cell-thick. Electron diffraction maxima from the larger lunar G.P. zones indicate that d100=18.52...
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...
Metamorphic infrastructure in the northern Ruby Mountains, Nevada
Keith A. Howard
1980, Book chapter, Cordilleran metamorphic core complexes
The metamorphic complex of the northern Ruby Mountains in northeastern Nevada exposes Paleozoic strata that are metamorphosed to sillimanite grade, migmatized, and recumbently folded. Nappes are variously overturned to the east, north, south, and west. The deeper part of this metamorphic infrastructure is a migmatitic zone pervaded by pegmatitic two-mica...
Geoscientists for international development
David A. Hastings

Geohydrology of southwestern Kansas
Edwin D. Gutentag, David H. Lobmeyer, Steven E. Slagle
1980, Open-File Report 80-218
Southwestern Kansas is one of the principal areas of ground-water development for irrigation in the State, and many reports are available concerning ground-water conditions in the area. The purposes of this investigation were to consolidate and update data, to determine the extent and effects of irrigation development on the ground-water...
Hydrogeologic data for Eureka Springs landfill and adjacent area, north-central Hillsborough County, Florida, 1969-73

1980, Open-File Report 80-70
Well location and construction data are summarized for 218 wells in the Eureka Springs landfill and adjacent areas in north-central Hillsborough County, FL. Most of the data are for 88 wells within the immediate vicinity of the landfill. Water-quality data are presented for 93 of the wells and 13 surface-water...

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...
