Hydrogeochemistry of Big Soda Lake, Nevada: An alkaline meromictic desert lake
Y.K. Kharaka, S.W. Robinson, LeRoy M. Law, W.W. Carothers
1984, Geochimica et Cosmochimica Acta (48) 823-835
Big Soda Lake, located near Fallon, Nevada, occupies an explosion crater rimmed by basaltic debris; volcanic activity apparently ceased within the last 10,000 years. This lake has been selected for a detailed multidisciplinary study that will ultimately cover the organic and inorganic hydrogeochemistry of water and sediments because the time...
THERMAL-INERTIA MAPPING IN VEGETATED TERRAIN FROM HEAT CAPACITY MAPPING MISSION SATELLITE DATA.
Ken Watson, Susanne Hummer-Miller
1984, Conference Paper
Thermal-inertia data, derived from the Heat Capacity Mapping Mission (HCMM) satellite, were analyzed in areas of varying amounts of vegetation cover. Thermal differences which appear to correlate with lithologic differences have been observed previously in areas of substantial vegetation cover. However, the energy exchange occurring within the canopy is much...
Floods of April 18, 1983 on St. Thomas and St. John, U.S. Virgin Islands
R. E. Curtis Jr.
1984, Water-Resources Investigations Report 84-4184
The U.S. Virgin Islands of St. Thomas and St. John experienced the most intense rainfall event in recorded history on April 18, 1983. Rainfall intensities of 2.5 inches per hour, and more than 16 inches in 18 hours were recorded. Almost instantaneous runoff caused widespread flooding near the coastlines of...
Upwarp of anomalous asthenosphere beneath the Rio Grande rift
E.C. Parker, P.M. Davis, J.R. Evans, H. M. Iyer, K.H. Olsen
1984, Nature (312) 354-356
Continental rifts are possible analogues of mid-ocean ridges, although major plate tectonic features are less clearly observed1. Current thermal models of mid-ocean ridges2-4 consist of solid lithospheric plates overlying the hotter, less viscous asthenosphere, with plate thickness increasing away from the ridge axis. The lithospheric lower boundary lies at or...

Modification of wave-cut and faulting-controlled landforms
Thomas C. Hanks, R.C. Bucknam, K. R. Lajoie, R. E. Wallace
1984, Journal of Geophysical Research Solid Earth (89) 5771-5790
From a casual observation that the form of degraded fault scarps resembles the error function, this investigation proceeds through an elementary diffusion equation representation of landform evolution to the application of the resulting equations to the modern topography of scarplike landforms. The morphologic observations can be analyzed either in the...

Current impact of DDE on black-crowned night-herons in the intermountain west
Charles J. Henny, Lawrence J. Blus, Alexander J. Krynitsky, Christine M. Bunck
1984, Journal of Wildlife Management (48) 1-13
Organochlorine contamination was studied in eight black-crowned night-heron (Nycticorax nycticorax) populations nesting in Washington, Oregon, and Nevada in 1978-80. DDE was detected in 220 eggs sampled; eggshell thickness was negatively correlated with residues of DDE and polychlorinated biphenyls (PCB's). Other contaminants were detected in 35% or fewer of the eggs....
Response of avian communities to herbicide-induced vegetation changes
Michael L. Morrison, E. Charles Meslow
1984, Journal of Wildlife Management (48) 14-22
The relationships between avian communities and herbicide modification of vegetation were analyzed on early-growth clear-cuts in western Oregon that had received phenoxy herbicide treatment 1 or 4 years previously. For both 1 and 4 years post-spray, vegetation development was greater in the third height interval (> 3.0 m) on untreated...

Deformation of clinopyroxenite: Evidence for a transition in flow mechanisms and semibrittle behavior
S. H. Kirby, A. K. Kronenberg
1984, Journal of Geophysical Research Solid Earth (89) 3177-3192
A systematic suite of constant strain rate experiments was performed on a vacuum-dried, high-purity, fine-grained clinopyroxenite using NaCl and NaF as confining media in a Griggs-type piston-cylinder apparatus. The experiments were carried out over a range of temperatures from 400° to 1100°C, strain rates from 10−3 to 10−7 s−1, and confining pressures...
Applied cartographic communication: map symbolization for atlases.
J. L. Morrison
1984, Cartographica: The International Journal for Geographic Information and Geovisualization (21) 44-84
A detailed investigation of the symbolization used on general-purpose atlas reference maps. It indicates how theories of cartographic communication can be put into practice. Two major points emerge. First, that a logical scheme can be constructed from existing cartographic research and applied to an analysis of the choice of symbolization...
Computation of free oscillations of the earth
Raymond P. Buland, F. Gilbert
1984, Journal of Computational Physics (54) 95-114
Although free oscillations of the Earth may be computed by many different methods, numerous practical considerations have led us to use a Rayleigh-Ritz formulation with piecewise cubic Hermite spline basis functions. By treating the resulting banded matrix equation as a generalized algebraic eigenvalue problem, we are able to achieve great...
Inter-pulse high-resolution gamma-ray spectra using a 14 MeV pulsed neutron generator

1984, Nuclear Instruments and Methods In Physics Research (219) 233-242
A neutron generator pulsed at 100 s-1 was suspended in an artificial borehole containing a 7.7 metric ton mixture of sand, aragonite, magnetite, sulfur, and salt. Two Ge(HP) gamma-ray detectors were used: one in a borehole sonde, and one at the outside wall of the sample tank opposite the neutron...
