William S. Platts, C.L. Armour, G.D. Booth, M. Bryant, J.L. Bufford, P. Cuplin, S. Jensen, G.W. Lienkaemper, G.W. Minshall, S.T. Monsen, R.L. Nelson, J.R. Sedell, J.S. Tuhy
1987, Report
Riparian area planning and management is a major national issues today--something that should have been the case a century ago. A century of additive effects of land use has resulted in major impacts on many riparian stream habitats and their fisheries, wildlife, and domestic livestock use. Before scientists can evaluate...
The Husting dilemma: A methodological note
James D. Nichols, Gary R. Hepp, Kenneth H. Pollock, James E. Hines
1987, Ecology (68) 213-217
Recently, Gill (1985) discussed the interpretation of capture history data resulting from his own studies on the red-spotted newt, Notophthalmus viridescens , and work by Husting (1965) on spotted salamanders, Ambystoma maculatum. Gill (1985) noted that gaps in capture histories (years in which individuals were not captured, preceded and...

Recording and processing procedures for multi-channel seismic-reflection data collected in the western Ross Sea, Antarctica
Shawn V. Dadisman, Holly F. Ryan, Dennis M. Mann
1987, Book chapter, The Anarctic continental margin geology and geophysics of the Western Ross Sea
During 1984, over 2300 km of multichannel seismic-reflection data were recorded by the U.S. Geological Survey in the western Ross Sea and Iselin Bank regions. A temporary loss and sinking of the streamer led to increasing the streamer tow depth to 20 m, which resulted in some attenuation of frequencies...
The stable isotopic composition of a phosphorite deposit: δ13C, δ34S, and δ18O
David Z. Piper, Y. Kolodny
1987, Deep Sea Research Part A, Oceanographic Research Papers (34) 897-911
The stable isotopes of carbon and sulfur in a major marine sedimentary phosphate deposit from the northwestern United States (the Phosphoria Formation of Permian age) characterize the chemical properties of the depositional environment. The δ34S and δ13C analyses suggest deposition under conditions of variable redox from a solution the acidity...
Rocky Mountains

1987, Book chapter, Geomorphic Systems of North America
The Rocky Mountain region is one of the most topographically distinct and impressive parts of North America. The Rocky Mountains rise abruptly above the bordering regions, particularly on the east and northeast where they are flanked by plains, less so on the west and southwest where they are bounded by...
Ionic conductivity of quartz: DC time dependence and transition in charge carriers
A. K. Kronenberg, Stephen H. Kirby
1987, American Mineralogist (72) 739-747
The time dependence of DC electrical conductivity in the c-axis direction of quartz can be accounted for by a transition in charge carriers from interstitial alkali impurities to interstitial H. The diffusive transport rates of Li, Na, and K are rapid parallel to c and have been shown to be...
Inorganic and organic geochemistry of Eocene to Cretaceous strata recovered from the lower continental rise, North American Basin, Site 603, Deep Sea Drilling Project Leg 93
Walter E. Dean, M.A. Arthur
1987, Initial Reports of the D.S.D.P. (93) 1093-1137
About one hundred samples of sediments and rocks recovered in Hole 603B were analyzed for type, abundance, and isotopic composition of organic matter, using a combination of Rock-Eval pyrolysis, C-H-N-S elemental analysis, and isotope-ratio mass spectrometry. Concentrations of major, minor, and trace inorganic elements were determined with a combination of...
I. Thermal evolution of Ganymede and implications for surface features. II. Magnetohydrodynamic constraints on deep zonal flow in the giant planets. III. A fast finite-element algorithm for two-dimensional photoclinometry
Randolph L. Kirk
1987, Thesis
The work is divided into three independent papers:PAPER I:Thermal evolution models are presented for Ganymede, assuming a mostly differentiated initial state of a water ocean overlying a rock layer. The only heat sources are assumed to be primordial heat (provided by accretion) and the long-lived radiogenic heat sources in the...
Disruption of the Mauna Loa magma system by the 1868 Hawaiian earthquake: Geochemical evidence.
Robert I. Tilling, J. Michael Rhodes, J. W. Sparks, John P. Lockwood, P. W. Lipman
1987, Science (235) 196-199
To test whether a catastrophic earthquake could affect an active magma system, mean abundances (adjusted for "olivine control") of titanium, potassium, phosphorus, strontium, zirconium, and niobium of historic lavas erupted from Mauna Loa Volcano, Hawaii, after 1868 were analyzed and were found to decrease sharply relative to lavas erupted before...
Analysis of trends in water-quality data for water conservation area 3A, the Everglades, Florida
Harold C. Mattraw Jr., Daniel J. Scheidt, Anthony C. Federico
1987, Water-Resources Investigations Report 87-4142
Rainfall and water-quality data bases from the South Florida Water Management District were used to evaluate water quality trends at 10 locations near or in Water Conservation Area 3A in The Everglades. The Seasonal Kendall test was applied to specific conductance, orthophosphate-phosphorus, nitrate-nitrogen, total Kjeldahl nitrogen, and total nitrogen regression...
Simulation of tidal flow and circulation patterns in the Loxahatchee River Estuary, southeastern Florida
Gary M. Russell, Carl R. Goodwin
1987, Water-Resources Investigations Report 87-4201
Results of a two-dimensional, vertically averaged, computer simulation model of the Loxahatchee River estuary show that under typical low freshwater inflow and vertically well mixed conditions, water circulation is dominated by freshwater inflow rather than by tidal influence. The model can simulate tidal flow and circulation in the Loxahatchee River...
Synopsis of wetland functions and values: bottomland hardwoods with special emphasis on eastern Texas and Oklahoma
D.L. Wilkinson, K. Schneller-McDonald, R.W. Olson, G.T. Auble
1987, Report, Biological Report
Bottomland hardwood wetlands are the natural cover type of many floodplain ecosystems in the southeastern United States. They are dynamic, productive systems that depend on intermittent flooding and moving water for maintenance of structure and function. Many of the diverse functions performed by bottomland hardwoods (e.g., flood control, sediment trapping,...
The physics of debris flows — A conceptual assessment

R. L. Beschta, T. Blinn, G. E. Grant, G. G. Ice, F. J. Swanson, editor(s)
1987, Conference Paper, Erosion and sedimentation in the Pacific Rim
Debris flows exhibit conspicuous dynamic interactions among their solid and fluid constituents. Key features of the interactions are neglected in traditional theories that treat debris flows as viscoplastic continua or as uniformly dispersed grain flows, but improved understanding of grain-grain and fluid-grain interactions has emerged from recent experimental and theoretical...

A nationwide State-Federal cooperative study was initiated in 1978 to examine effects of September hunting on nesting mourning doves (Zenaida macroura). This study was designed to (1) determine the proportion of the annual total of dove nesting activity and production that occurs in September and October, and (2) determine if...

Thermal evolution models are presented for Ganymede, assuming a mostly differentiated initial state of a water ocean overlying a rock layer. The only heat sources are assumed to be primordial heat (provided by accretion) and the long-lived radiogenic heat sources in the rock component. As Ganymede cools, the ocean thins,...
