Loss of lampricides by adsorption on bottom sediments
V. K. Dawson, D.A. Johnson, J. L. Allen
1986, Canadian Journal of Fisheries and Aquatic Sciences (43) 1515-1520
Problems have been encountered in maintaining effective concentrations of the lampricides 3-trifluoromethyl-4-nitrophenol (TFM) and 5,2a??-dichloro-4a??-nitrosalicylanilide (Bayer 73) during treatments of certain Great Lakes tributaries. Concentrations of Bayer 73 decreased by more than 80% in a portion of the Ford River, Michigan, during treatment in 1980. Adsorption of Bayer 73 on...
DEBRIS FLOWS AND HYPERCONCENTRATED STREAMFLOWS.
Gerald F. Wieczorek
1986, Conference Paper
Examination of recent debris-flow and hyperconcentrated-streamflow events in the western United States reveals (1) the topographic, geologic, hydrologic, and vegetative conditions that affect initiation of debris flows and (2) the wide ranging climatic conditions that can trigger debris flows. Recognition of these physiographic and climatic conditions has aided development of...
A paleomagnetic and stable isotope study of the pluton at Rio Hondo near Questa, New Mexico: Implications for CRM related to hydrothermal alteration
J.T. Hagstrum, C.M. Johnson
1986, Earth and Planetary Science Letters (78) 296-314
Paleomagnetic and rock magnetic data combined with stable isotope data from the middle Tertiary pluton along the Rio Hondo in northern New Mexico suggest that its magnetic remanence has both thermal (TRM) and high-temperature chemical (CRM) components. Oxygen isotope temperatures indicate...
SULFUR CONTENT OF THE COAL RESOURCES OF THE UNITED STATES: CURRENT STATUS.
C. B. Cecil, F.T. Dulong
1986, Conference Paper, Preprint - Society of Mining Engineers of AIME
The sulfur content of United States coal can be assessed using a variety of approaches. The sulfur content may be expressed in terms of total sulfur in the coal, pounds of sulfur per million Btu, or sulfur remaining after reduction by coal preparation. In addition, sulfur content may be applied...
Mineralogical studies of the nitrate deposits of Chile. V. Iquiqueite, Na4K3Mg(CrO4)B24O39(OH).12H2O, a new saline mineral.
G. E. Ericksen, M.E. Mrose, J.W. Marinenko, J. J. McGee
1986, American Mineralogist (71) 830-836
Iquiqueite (Na4K3Mg(CrO4)B24O39(OH).12H2O, a 11.6369(14), c 30.158(7) A, P31c, Z = 3) occurs as a widespread minor constituent in the nitrate fields of northern Chile. It is particularly abundant in the vicinity of Zapiga, Tarapaca province. Associated minerals include nitratite, halite, nitre, darapskite, blodite, glauberite, dietzeite, bruggenite, ulexite and gypsum. Iquiqueite...
Geostatistical analysis of gas potential in Devonian shales of West Virginia
M.E. Hohn, D. W. Neal
1986, Computers & Geosciences (12) 611-617
The geologic processes that control the occurrence of gas in the Devonian shales of West Virginia are understood poorly. Locating a new Devonian shale well may depend upon proximity to known producing wells. Maps of initial potentials and probability of success can play an important role in exploration and development....
Development of labd cover and terrain databases for the Innoko National Wildlife Refuge, Alaska, using LANDSAT and digital terrain data
Carl J. Markon, Stephen S. Talbot
1986, Conference Paper, Technical Papers of the American Society of Photogrammetry, Fall Technical Meeting
Landsat-derived land cover maps and associated elevation, slope, and aspect class maps were produced for the Innoko National Wildlife Refuge (3,850,000 acres; 1,555,095 hectares) in northwestern Alaska. These maps and associated digital data products are being used by the U. S. Fish and Wildlife Service for wildlife management, research, and...
Planning for optical disk technology with digital cartography.
D.L. Light
1986, Photogrammetric Engineering and Remote Sensing (52) 551-557
A major shortfall that still exists in digital systems is the need for very large mass storage capacity. The decade of the 1980s has introduced laser optical disk storage technology, which may be the breakthrough needed for mass storage. This paper addresses system concepts for digital cartography during the transition...
Isolation and detection of Giardia cysts from water using direct immunofluorescence
Stephen K. Sorenson, John L. Riggs, Peter D. Dileanis, Thomas J. Suk
1986, Water Resources Bulletin (22) 843-845
A water‐sampling apparatus used for the isolation and detection of Giardiacysts in water has been designed and tested. The sampling apparatus uses one of a variety of pumps or waterline pressure to move water through a filter. Two of the optional pumps are lightweight enough to make the apparatus portable and...
Digital merging of Landsat TM and digitized NHAP data for 1:24 000-scale image mapping.
P.S. Chavez Jr.
1986, Photogrammetric Engineering and Remote Sensing (52) 1637-1646
Merging image data collected by different remote sensors is becoming an increasingly important component of digital processing. In this study, two data sets with very different characteristics were digitally merged, and a single data set, which contains information from both sets, was generated. Landsat Thematic Mapper (TM) data were selected...
Brine and gas recovery from geopressured systems
S.K. Garg, T.D. Riney, R. H. Wallace Jr.
1986, Geothermics (15) 23-48
A series of parametric calculations was run with the geopressured—geothermal simulator MUSHRM to assess the effects of important formation, fluid and well parameters on brine and gas recovery from geopressured reservoir systems. The specific parameters considered are formation permeability, pore-fluid salinity, temperature and gas content, well radius and location with...
Pb, Sr, Nd, and Hf isotopic constraints on the origin of Hawaiian basalts and evidence for a unique mantle source
P. Stille, D.M. Unruh, M. Tatsumoto
1986, Geochimica et Cosmochimica Acta (50) 2303-2319
Pb, Sr, Nd, and Hf isotopic relationships among basalts from the Hawaiian Islands suggest that these basalts were derived from three sources; the oceanic lithosphere (Kea end member), the depleted asthenosphere (posterosional end member) and a deep-mantle plume (Koolau end member).Hawaiian tholeiites are derived within the lithosphere and the isotopic...
