G. L. Bullock, R. L. Herman, C. Waggy
1991, Journal of Aquatic Animal Health (3) 48-50
Three hatchery trials were carried out to determine the efficacy of chloramine-T for the control of bacterial gill disease in rainbow trout Oncorhynchus mykiss, ranging in weight from 2.5 to 54 g. In each trial, we used a single flow-through treatment of 8.5 mg chloramine-T/L. The single...

Calibration of a texture-based model of a ground-water flow system, western San Joaquin Valley, California
Steven P. Phillips, Kenneth Belitz
1991, Ground Water (29) 702-715
The occurrence of selenium in agricultural drain water from the western San Joaquin Valley, California, has focused concern on the semiconfined ground-water flow system, which is underlain by the Corcoran Clay Member of the Tulare Formation. A two-step procedure is used to calibrate a preliminary model of the system for...
Visible and near-infrared (0.4-2.5 μm) reflectance spectra of playa evaporite minerals
James K. Crowley
1991, Journal of Geophysical Research (96) 16231-16240
Visible and near-infrared (VNIR; 0.4–2.4 μm) reflectance spectra were recorded for 35 saline minerals that represent the wide range of mineral and brine chemical compositions found in playa evaporite settings. The spectra show that many of the saline minerals exhibit diagnostic near-infrared absorption bands, chiefly attributable to vibrations of hydrogen-bonded...
Institutional issues affecting the integration and use of remotely sensed data and geographic information systems
D. T. Lauer, J. E. Estes, J.R. Jensen, D. D. Greenlee
1991, Photogrammetric Engineering and Remote Sensing (57) 647-654
The developers as well as the users of remotely sensed data and geographic information system (GIS) techniques are associated with nearly all types of institutions in government, industry, and academia. Individuals in these various institutions often find the barriers to accepting remote sensing and GIS are not necessarily technical in...
Implications of low-temperature cooling history on a transect across the Colorado Plateau-Basin and Range boundary, west central Arizona
B. Bryant, C. W. Naeser, J.E. Fryxell
1991, Journal of Geophysical Research (96) 12375-12388
Fission track ages of apatite and zircon from metamorphic, plutonic, and sedimentary rocks along a 80-km transect across the Colorado Plateau-Basin and Range boundary in west central Arizona show differences in the low-temperature cooling histories between the provinces. The transect extends from Cypress Mountain in...
Isotopic and chemical constraints on the petrogenesis of Blackburn Hills volcanic field, western Alaska
E. J. Moll-Stalcup, Joseph G. Arth
1991, Geochimica et Cosmochimica Acta (55) 3753-3776
The Blackburn Hills volcanic field is one of several Late Cretaceous and early Tertiary (75–50 Ma) volcanic fields in western Alaska that comprise a vast magmatic province extending from the Arctic Circle to Bristol Bay. It consists of andesite flows, rhyolite domes, a central granodiorite to quartz monzonite pluton, and...

1991, Nature (354) 223-227
The Kenya rift is one of the classic examples of a continental rift zone: models for its evolution range from extension of the lithosphere by pure shear1, through extension by simple shear2, to diapiric upwelling of an asthenolith3. Following a pilot study in 19854, the present work involved the shooting...
Thermodynamic assessment of hydrothermal alkali feldspar-mica-aluminosilicate equilibria
D.A. Sverjensky, J.J. Hemley, W. M. d’Angelo
1991, Geochimica et Cosmochimica Acta (55) 989-1004
The thermodynamic properties of minerals retrieved from consideration of solid-solid and dehydration equilibria with calorimetric reference values, and those of aqueous species derived from studies of electrolytes, are not consistent with experimentally measured high-temperature solubilities in the systems K2O- and Na2O-Al2O3-SiO2-H2O-HCl (e.g., K-fs — Ms — Qtz — K+ — H+)....
Geochemistry of dissolved inorganic carbon in a Coastal Plain aquifer. 2. Modeling carbon sources, sinks, and δ13C evolution
Peter B. McMahon, Francis H. Chapelle
1991, Journal of Hydrology (127) 109-135
Stable isotope data for dissolved inorganic carbon (DIC), carbonate shell material and cements, and microbial CO2 were combined with organic and inorganic chemical data from aquifer and confining-bed pore waters to construct geochemical reaction models along a flowpath in the Black Creek aquifer of South Carolina. Carbon-isotope fractionation between DIC and...
Geochemistry of a Tertiary sedimentary phosphate deposit: Baja California Sur, Mexico
D.Z. Piper
1991, Chemical Geology (92) 283-316
The San Gregorio Formation in Baja California Sur, a phosphate-enriched sedimentary unit of late Oligocene to early Miocene age, has been analyzed in two areas (La Purisima and San Hilario) for its chemical composition (major oxides, Cu, Cd, Cr, Co, V, and rare-earth elements - REE) and isotopic composition (??18O...

1991, Radiocarbon (33) 151-164
We report 63 new radiocarbon analyses of samples from São Miguel, the largest (ca 62 × 13km) and most populous (ca 150,000 inhabitants) island in the Azores archipelago (Fig 1). The samples are mainly carbonized tree roots and other plant material collected from beneath 20 mafic lava flows and spatter...

Convergent radial dispersion: A note on evaluation of the Laplace transform solution
Allen F. Moench
1991, Water Resources Research (27) 3261-3264
A numerical inversion algorithm for Laplace transforms that is capable of handling rapid changes in the computed function is applied to the Laplace transform solution to the problem of convergent radial dispersion in a homogeneous aquifer. Prior attempts by the author to invert this solution were unsuccessful for highly advective...

A line transect model for aerial surveys
Pham Xuan Quang, Richard B. Lanctot
1991, Biometrics (47) 1089-1102
We employ a line transect method to estimate the density of the common and Pacific loon in the Yukon Flats National Wildlife Refuge from aerial survey data. Line transect methods have the advantage of automatically taking into account “visibility bias” due to detectability difference of animals at different distances from...

Comparison of three different methods to merge multiresolution and multispectral data: Landsat TM and SPOT panchromatic
P.S. Chavez Jr., S.C. Sides, J.A. Anderson
1991, Photogrammetric Engineering and Remote Sensing (57) 295-303
The merging of multisensor image data is becoming a widely used procedure because of the complementary nature of various data sets. Ideally, the method used to merge data sets with high-spatial and high-spectral resolution should not distort the spectral characteristics of the high-spectral resolution data. This paper compares the results...
Source of atrazine and desethylatrazine in a river, during base flow
Paul J. Squillace, E. Michael Thurman, Edward E. Fischer, Phil J. Soenksen
1991, Conference Paper
A budget of atrazine and desethylatrazine loads was computed for a 116-kilometer reach of the Cedar River in Iowa to determine where these compounds enter the river during base-flow conditions. Loads were determined by measuring discharge and concentrations of the compounds for four main-stem sites along the Cedar River and...

Publication aspects of ethics in photogrammetry
Morris M. Thompson
1991, Photogrammetric Engineering and Remote Sensing (57) 161-162
According to the Code of Ethics of the American Society for Photogrammetry and Remote Sensing (ASPRS), the principles on which ethics are founded consist of honesty, justice, and courtesy, forming a moral philosophy associated with mutual interest among men. We will cover in particular the ethical problems of publication of...
