1987, Oceanus (30) 42-52
The Venezuelan and Colombian basins are located on the Caribbean Plate whilst the Yucatan basin is on the North American Plate. The processes occurring at the boundaries between the Caribbean Plate and the adjacent North American, South American and Cocos Plates, and the resulting surface features and patterns of volcanic...
Diffusivity of a glacial-outwash aquifer by the floodwave- response technique
R.J. Reynolds
1987, Groundwater (25) 290-299
Aquifer diffusivity (transmissivity divided by storage coefficient) was calculated for three sites in a glacial-autwash valley aquifer near Cortland, New York from water-level fluctuations induced by rises in stream stage. The observed response data were analyzed through use of a one-dimensional floodwave-response model to calculate the theoretical head response in...
Residence of silver in mineral deposits of the Thunder Mountain caldera complex, Central Idaho, U.S.A.
B. F. Leonard, R.P. Christian
1987, Mineralogy and Petrology (36) 151-168
Silver is an accessory element in gold, antimony, and tungsten deposits of the caldera complex. Most of the deposits are economically of low grade and genetically of xenothermal or epithermal character. Their gold- and silver-bearing minerals are usually disseminated, fine grained, and difficult to study. Sparsely disseminated pyrite and arsenoprite...
Volcanic processes in the Solar System
M. H. Carr
1987, Earthquakes & Volcanoes (USGS) (19) 128-137
This article stresses that terrestrial volcanism represents only part of the range of volcanism in the solar system. Earth processes of volcanicity are dominated by plate tectonics, which does not seem to operate on other planets, except possibly on Venus. Lunar volcanicity is dominated by lava effusion at enormous rates....

Immunostimulation of antibody-producing cells and humoral antibody to fish bacterins by a biological response modifier
T. Kitao, T. Yoshida, D. P. Anderson, O. W. Dixon, A. Blanch
1987, Journal of Fish Biology (31) 87-91
Numbers of splenic antibody-producing cells and humoral antibody titres were elevated during immunization regimes in rainbow trout when the bacterins Yersinia ruckeri or Aeromonas salmonicida O-antigen preparations were mixed with the immunostimulator FK-565. Fish sampled 14 days after injection showed a marked increase in the immune response when doses of 5, 10 or 100...
Oxidized Nitrogen in Precipitation, Throughfall, and Streamfall from a Forested Watershed in Oklahoma
Stephen J. Lawrence, Parker J. Wigington Jr.
1987, Water Resources Bulletin (23) 1069-1076
Oxidized nitrogen (nitrite plus nitrate N) concentrations were measured from bulk precipitation, bulk throughfall, and screamflow in a 7. 86 hectare forested watershed in southeastern Oklahoma during the wet season from March through June 1983. Oxidized nitrogen inputs comparable to results of other studies were recorded during the 19 rainstorms...

Reassessment of the volkonskoite-chromian smectite nomenclature problem.
Eugene E. Foord, Harry C. Starkey, Joseph E. Taggart Jr., Daniel R. Shawe
1987, Clays and Clay Minerals (35) 139-149
The name volkonskoite was first used in 1830 to describe a bright blue-green, chromium-bearing clay material from the Okhansk region, west of the Ural Mountains, U.S.S.R. Since that time, the name has been applied to numerous members of the smectite group of clay minerals, although the reported chromium content has...
Isotopic composition of pyrite: Relationship to organic matter type and iron availability in some North American cretaceous shales
D. L. Gautier
1987, Chemical Geology: Isotope Geoscience Section (65) 293-303
The S isotope composition of pyrite in Cretaceous shales from the Western Interior of North America is related to organic C abundance, kerogen type and Fe availability. Both calcareous and noncalcareous rocks show a correlation between S and C, but noncalcareous...
ESTIMATING LOW-FLOW FREQUENCIES OF UNGAGED STREAMS IN NEW ENGLAND.
S. William Wandle Jr.
1987, Conference Paper
Equations to estimate low flows were developed using multiple-regression analysis with a sample of 48 river basins, which were selected from the U. S. Geological Survey's network of gaged river basins in Massachusetts, New Hampshire, Rhode Island, Vermont, and southwestern Maine. Low-flow characteristics are represented by the 7Q2 and 7Q10...
Immunization of salmonids against Yersinia ruckeri: Significance of humoral immunity and cross protection between serotypes
R. C. Cipriano, T. Ruppenthal
1987, Journal of Wildlife Diseases (23) 545-550
Brook trout (Salvelinus fontinalis) were immunized with bacterins containing either Serotype 1 or 2 isolates of Yersinia ruckeri to determine the relative degree of cross-protection afforded when the fish were challenged with the homologous or heterologous serotype. While fish immunized with pH-lysed bacterins produced highly...
Ecological aspects of microorganisms inhabiting uranium mill tailings
C.L. Miller, E. R. Landa, D.M. Updegraff
1987, Microbial Ecology (14) 141-155
Numbers and types of microorganisms in uranium mill tailings were determined using culturing techniques. Arthrobacter were found to be the predominant microorganism inhabiting the sandy tailings, whereas Bacillus and fungi predominated in the slime tailings. Sulfate-reducing bacteria, capable of leaching radium, were isolated in low numbers from tailings samples but...
Interactions among dietary minerals, arginine and lysine in rainbow trout (Salmo gairdneri)
Y. N. Chiu, R. E. Austic, G. L. Rumsey
1987, Fish Physiology and Biochemistry (4) 45-55
Studies were conducted to determine whether interactions occur among dietary lysine, arginine and monovalent minerals in rainbow trout. In one experiment, rainbow trout fingerlings were fed diets containing three levels of lysine (2.4, 3.1 and 3.8 g per 100 g diet), two levels of arginine (1.7 and 2.5 g per...

Slab pull and the seismotectonics of subducting lithosphere
William Spence
1987, Reviews of Geophysics (25) 55-69
This synthesis links many seismic and tectonic processes at subduction zones, including great subduction earthquakes, to the sinking of subducted plate. Earthquake data and tectonic modeling for subduction zones indicate that the slab pull force is much larger than the ridge push force. Interactions between the forces that drive and...
Growth and survival of fingerling lake trout reared at four densities
R. W. Soderberg, D.S. Baxter, W. F. Krise
1987, Progressive Fish-Culturist (49) 284-285
Fingerling lake trout (Salvelinus namaycush) were reared at density indexes (fish density, in pounds per cubic foot, divided by fish length in inches) of 0.25, 0.50, 1.0, and 2.0. Final lengths, weights, condition factors, and mortality rates did not differ among the treatments. We conclude that fingerling lake trout may...
Transmission of infectious pancreatic necrosis virus in striped bass, Morone saxatilis (Walbaum)
S.J. Wechsler, L.C. Woods, J.N. Kraeuter, F. M. Hetrick, P. E. McAllister
1987, Journal of Fish Diseases (10) 29-34
Infectious pancreatic necrosis virus (IPNV) did not cause increased mortality in experimentally challenged striped bass, Morone saxatilis (Walbaum). Fry became transiently infected after waterborne challenge but fingerlings were resistant to that route. However, striped bass fingerlings readily became chronic virus carriers following ingestion of IPNV-contaminated food. Vertical...
Diagenesis and fluid flow in the San Juan Basin, New Mexico - regional zonation in the mineralogy and stable isotope composition of clay minerals in sandstone.
C. Gene Whitney, H. R. Northrop
1987, American Journal of Science (287) 353-382
The Westwater Canyon Member of the Upper Jurassic Morrison Formation is a relatively homogeneous, hydrologically continuous 100-m-thick sequence of massive fluvial sandstone, bounded above and below by relatively heterogeneous, hydrologically discontinuous units and has served as a primary conduit for fluids within this stratigraphic interval. Patterns of mineral-fluid reactions suggest...
Methods of controlling growth of steelhead
R. R. Smith
1987, Progressive Fish-Culturist (49) 248-252
Steelhead (Salmo gairdneri) held at 15°C and fully fed from demand feeders grow larger than desired by the time of their normal release into streams. The effect of limited feed intake on growth, body composition, and potential for migration to the sea was investigated. Dilution of feed by 10‐40% with...
